Ok guys, I have some paint and panel questions and I'm hoping the knowledge in this group can sort me out..

This is what I have,

Australian delivered 53G prefix,

Yamaha 47X markings on the undersides of all panels,

I can see,

solid white base, solid red speed ladders over the top with definite stencil line.

Blue line decal incorporating white line up to the red ladders. (Except on belly pan, only blue line)

No clear coat on anything except the fuel tank.

Any advise most appreciated.

To me this appears to be original paintwork but I'm no expert

Gents — Yamaha RZ500 Australia

Gents,

As you might know my hobby is restoring back to factory standard, the one thing that really annoys me is the lack of electro platters that understand how passionate (or anal) we get bringing our project up to factory specification. At last I have found an electro platter that shares our passion, I took the time to go and see him yesterday and was really impressed by his premises and his attitude, he showed me some of his work and I was blown away, perfect finish to show standard. After talking to him for a while he confirmed that he could electro plate drab olive green and black, these are the two colour I can’t get refinished here and had actually looked at sending some parts to the UK to obtain the required finish. I feel it only right to support this fella as he is a one man shop, I will post some before and after picture when I collect my parts but please feel free to call him, mention that you have read this post. His name is Rick and his number is 0413826092 or rickferguson74@gmail.com

    Fans.

    Sorry I have been a bit quiet about this as I can't believe it really yet!

    Picked up my RZV a week ago.

    I raced one when I was a nipper so to have one now again is amazing. Should say I had a RZ only but never the less.

    Extremely honest bike. Could do with some plastic repairs and paint etc but mechanically very sound. I think it may be still restricted so any advice would be appreciated. In time I will be looking for a set of after market race pipes. But for now up to Mt Glorious!

    Cheers. DL.

    Is thanks to Craig Bullen for phone support!

      Just been for a proper ride in the hills on the RZV and all the new parts , brake lines, pads, fork springs, tyres made a massive difference. It's like a new bike. I'm totally blown away how good they are to ride and you can ride them real fast without worrying that it's gonna get away from you.

      Just love it and definitely a forever keeper and that's saying something for me !!

      She's a thirsty old girl tho haha!!

        What'll it do mister? More than 180kph son! Just spent an inordinate amount of time converting a FZ750 240kph speedo into a RZV500 speedo (which just meant adjusting the kms to match and swapping the needles over - sounds easy, takes ages!). Also swapped the rev counter for a RZ250 unit which doesn't have the speed warning and replaced the cracked temp/gauge glass. Job done.

          So Richard Morrison I'd put that 14 tooth front onto your as fast as poss mate as it's a bloody hoot with it on. Makes loads of difference. Much easier to keep in the powerband especially for road riding. If I was on a track then 15 would be fine. Also definitely getting rid of these hideous (ATV like) Pirelli Demon tyres. Just took in on a twisty run and lost the back end twice which was enough to turn round get home and order two new Avon Roadriders... it's stinking hot out here as well so u'd expect em to be nice n sticky but they feel soapy. Probly just old although they look brand new.

            Hi all — Yamaha RZ500 Australia

            Hi all,

            I have a huge problem with my RZV500. On Sunday, I hit an oil slick, and dropped it on the right side. There is some fairing damage, two blinkers are damaged, the side panel, and lower fairing is damaged, the rear faring is c, the exhaust pipe is scratched and damaged ,and the right case is cracked.

            The bike is insured, and a claim has been lodged, however I now need a repair quote.

            Does anyone have reccomendations for this? I am in Wagga Wagga NSW, transport to a repairer is not an issue, that is covered on the policy.

            All advice gratefully recieved.

              Just been for a proper 120k blat in the hinterland to give the old girl a proper clean out. Sht loads of fun but also pointed out a few things that need sorting.

              Suffered brake fade so will totall overhaul all calipers and pads (any suggestions for pads, I don't really care about price as I never scrimp on them !)

              Also forks bottomed out on hard(ish) braking and dodgy road surface. I'm guessing a fork service will help but I'd like to hear from people that have swapped springs or upgraded originals to make them more efficient.

              Apart from getting roasted arse cheeks it was an awesome machine to ride.

                Rego today!! ( yea yea I know the plate is the wrong year but it's a spare until the new one's here)

                First ride and it's pretty hair raising but shit loads of fun.

                Rear end flicked out as it hit the PB going round a bend.. woohoo. Feisty one :-)

                I read the first gear is a little long and high which I agree with. And not needing it's top end living in "watch ur speed or u will go to jail" Australia has anyone got different ratio to standard that they are using that works nicely. I'll change chain and sprockets anyway as always with a new bike !

                  OK so the RZV turned up today but the needle valves are buggered as it started to piss out fuel which of course i'm not happy about but fairly standard with a 2T thats not been used much recently. Also i read the emulsion tubes need changing from 10 holes to 14 holes (RD500) to totally unrestrict it (apart from pipes which have already been changed).

                  Anyone have the Mikuni part numbers for the needle valves (and emulsifying tubes) or are they the same valves as on other LCs?

One is now completely restored to mint stock condition, the other one is displayed here. I can now say that I have breathed new life into two almost dead RZ/RD 500s!

                          Following are details of my project RZ500. I always dreamed about the Yamaha GP-replica two-strokes in the '80s while riding the Angeles Crest Hwy outside L.A. and never thought you could come so close. Today, at age 45, I'm taken back to the good old days. Long live the two-stroke GP-replica for its amazing power and unquestionable beauty. I currently have a second one in the works that I'm collecting parts for. I'm also thinking about running this at Bonneville with different gearing just for the fun of it!

                          Special thanks go to Wyn Belorusky, whose bike I first saw on the RZ/RD 500 Owners Group web site and freaked out over it. I must have bugged the crap out of him, calling so much for information. Also, thanks to my in-house machinist, Kevin Goddard, who was fast to help with the steering stem conversion.

                            1985 RZ500 - NAKED!

                            Owner: George Nolan, Indianapolis, IN USA

                            I acquired this RZ500 in 1991. It is a very early model, serial number 128 (101 was the first production model). Unfortunately, it was in poor condition when I got it. The bodywork was in tatters, the tires were bald, and it was filthy. It even had bondo covering dents in the lower exhaust pipes! During the next few months I did a clean-up and overhaul, including new pistons & rings (the cylinder bores were still within spec), Nikon exhaust pipes and Airtech seat and fairing. After this rebuild, I rode the bike for a couple of years. However, I wasn't happy with the looks of the bike. I've always liked looking at the mechanical bits on motorcycles, but the full fairing covered up all of the neat parts.

                            I disassembled the bike again, and made plans for the next iteration. I've always admired the style of the Ducati Monster, which blends road racer performance with a naked bike look. I decided that was what I wanted the RZ to look like. Merely removing the fairing didn't cut it, there were too many things bolted to the frame and buried beneath the fairing that needed attention.

                            I started by relocating the electrical parts (power valve control, CDI box, ignition coils and rectifier/regulator) onto a plate mounted under the tank, in the area where the airbox originally was. I used Wyn Belarusky's air filter kit to eliminate the stock airbox components (I designed and CNC machined new outer covers, since they were so visible). On the bottom side of the plate are the ignition switch, choke lever, fuel petcock and the horn. Brackets were welded onto the frame for the oil tank, electrical panel, and rear bodywork. All of the unused brackets were removed, and unused mounting holes were welded shut. An aluminium oil tank was fabricated to fit under the seat, between the top pipes (it holds 1.5 quarts of Motul 600 2T oil). I also made a small battery box for the 12v 1.3A battery.

                            he stock RZ swingarm has an aluminium brace welded to it, along with a bracket for the rear caliper. The brace provides a convenient mount for a carbon fiber Suzuki GSXR750 hugger fender (Carbon Works). The rear wheel is from a Suzuki GSXR 1000, tire is a Michelin Pilot Sport, 180-55 ZR 17. The wheel and sprocket carrier were machined to correct the sprocket alignment. I converted to a 520 chain, to save a little weight. The rear sprocket is 42 teeth, the front is 16. With the change in wheel circumference, this combination is very close to stock gearing. (Sprocket Specialities).

                              Race-Ready RD500LC

                              Owner: Giuseppe Natalini, Rome, Italy

                              I started to update my '85 RD500 many years ago, and at the time I didn't have an end target in mind. The sportbikes available in the market at that time were big, heavy, ugly and "four-stroke." I was looking for something "special," a 500GP replica two-stroke!

                              After tons of early modifications, two years ago I finally understood (better late than never) the best way to build up my RD500 was to have a clear target in mind. And that target was: just enough engine power to not compromise reliability but still have plenty of bottom and middle rpm thrust. Ultimate handling, and lightness as much as possible, too.

                              I use my RD on racetracks only. Everyone who has tried their street motorcycle on a racetrack knows that's a hard test for a bike. Everything must work at 100% - engine, carburetion, gears and suspension. Well, after finishing my project, I can say only one thing about my bike - this machine is absolutely wonderful!

                              Engine

                              500cc, V-4, 2-stroke

                              Pistons are shorter than standard, and reshaped to have the same weight on each cylinder. Using TZR125 pistons

                              Exhaust ports measure 37mm in diameter, worked at the limit of the YPVS valve, instead of std 32mm

                              Reed valves reshaped and measure 37 x 37mm, worked inside for 16+3 mm, instead of std 30 x 37.5 mm. Fiberglass reeds are by Aktive

                                '91 Rainey Replica RZ500

                                Owner: Mike Cichetti, Huntingdon Valley, PA USA

                                This bike is dedicated to all of us who think that valves are for toilets, and love the sight of blue smoke.

                                I'd like to give special thanks on this project to BJ MacDonald, who is responsible for this machine. He created a true street-going replica of the 1991 World Championship bike. The attention to detail is phenomenal, and I couldn't be more pleased. Without his genius and hard work none of this would have been possible.

                                Other who helped make this project a reality include Wyn Belorusky, who made all the brackets, silencers, created the kick stand and supplied the body work and a ton of encouragement and sage advice. Lee Buzelek, who supplied the donor machine, all the guys at the BikeWorks in Glenside, and of course to my lovely wife Lynne, who puts up with my lunacy and can scare BJ.

                                We don't need no stinking valves...!

                                  Spondon F1 Yamaha RD500 — Yamaha RZ500 Australia

                                  Spondon F1 Yamaha RD500

                                  Ex Brian Reid Yamaha 500 V4 F1 Spondon Racer.

                                  This machine was built especially for the F1 world championship in 1985, it had taken months of preparation & some £25,000 in funds to get this machine ready in time for the IOM TT races, but going to the TT races in a fishing boat ended in disaster as the boat the Tornamona Lass skippered by Archie Lappin and with Joey & Robert Dunlop as passengers, foundered on rocks and this machine along with some others sank to the bottom of the sea, the machine was brand new and had not even raced yet.

                                  The machine was eventually recovered rebuilt and prepared for the TT races, Brian lapped the circuit at 107.05mph on the first lap of the F1 race but later retired at Hanley’s when the carburetor blew off. The frame is a Spondon beam, the engine was built by Arnie Fletcher and Robin Church from Len Manchester Motorcycles, the engine in 1985 was giving out 150Bhp on the test bench, timing 1mm BTDC, short reach plugs fitted, 280 main jets, 35º squish, piston clearance 2.6 thou. Brian Reid was able to pass a TZ750 Yamaha easy at the UGP. The wheels are special 16" Dymag items, and the exhausts are Len Manchester made,the ignition is Hitachi TZ500, the forks were changed some time during 85 from Spondon to RG500.

                                    Twenty years ago the legendary Giacomo Agostini and his then unconventional... — Yamaha RZ500 Australia

                                    Twenty years ago, the legendary Giacomo Agostini and his then-unconventional "gill-valved," water-cooled Yamaha YZR500 two-stroke dethroned the mighty MV-Agusta Gran Prix juggernaut, ending MV's unprecedented 17-year win streak. Several years later Kenny Roberts gave the marque three consecutive GP titles, and fans around the world dreamt of what riding a 500cc Yamaha racebike would be like.

                                    Skip forward to 1984, and Yamaha brought the dream one step closer to reality when they introduced the 500cc V-Four RZ500.

                                    Inspired by the YZR500 factory racer ridden by Roberts during the 1983 GP season, the twin-crank V4 was the closest thing to a Gran Prix bike (with lights) that you could get your hands on. From it's GP-style full fairing to the water-cooled, four-cylinder two-stroke engine nestled in a perimeter-style box section frame, the RZ500 was a dream-come-true for race enthusiasts world wide, and naturally, it became a highly lusted-after machine.

                                    Problem was, due to Environmental Protection Agency anti-pollution mandates, the RZ500 was never sold in the United States (at least not legally), but you can bet a few regulations didn't stop enterprising two-stroke lovers from jumping on the contraband express and importing an RZ or four.

                                    Three different versions of the red and white bike were available worldwide. The RZ500, which came equipped with Yokohama OEM tires, was sold in Australia, New Zealand and Canada. Its European counterpart, the RD500LC , while mechanically identical, sported Michelin tires and a different paint scheme (photo at right). Japan received a limited-edition RZV500R, replete with a lighter aluminum frame (the others used steel) and other trick goodies, but a lso suffered from a de-tuned engine.

                                    Kenny Roberts' 1983 OW-70 GP bike used a very unique 50-degree, twin crank V-four motor equipped with Yamaha's YPVS exhaust power valves, and this same basic design configuration was shared by the RZ: With it's twin cranks, the engine actually functions as a pair of 180-degree parallel twins geared together. Both Roberts' YZR and the RZ500/RD500LCs had removable cassette-style six-speed gearboxes. But this is where the similarities end.

                                      One of the RZV's I considered when looking for one earlier in the year. Looked ok in the pics (bike was still in Japan at the time) but had a bit of fairing damage & crazed paint up close and a few other things that put me off. Didn't stop it selling for $15k once it got to Oz.
