Ok so I bought a blaster and the guy I bought it from said to mix 50:1 ratio because he has tune it for winter and 50:1. But almost everyone prefer 32:1 will it be bad to try 32:1 for the jet size? .. pictures for attention thanks everyone

  • You would definitely go up a few jet sizes before going to 32:1 because it would be running lean due to the oil displacing the fuel

  • The higher the number is more oil?

  • And running 32:1 would probably be better for piston lubrication

  • No 50:1 is 50 parts gas 1 part oil and 32:1 is 32 parts gas and 1 part oil, so really there is more oil in 32:1

  • Basically the way it would work 50 to 1 is a lien mix I'm willing to bet he has a jetted out at 2:30 somewhere around there so to run 32 to 1 you would probably want to go up to 300 if that makes any sense the lien or the mix the smaller the jet the thicker the mix the bigger the jet to allow better fuel flow

  • Lower the number the richer it is. Higher the number the more lean

  • And yes definitely better to run 32:1 on blasters

  • 50:1 is like weed eater ratio. Far to lean imo

  • Terry Preston can answer this question and any other

  • Might run a tad bit better being lean until it seizes up and your done riding haha

  • If the carb is jetted to the oil ratio, one can use any ratio between 20:1 and 50:1.

    The recommended ratio for a Blaster is 32:1 for recreational riding and 25:1 for racing.

    One can use a 50:1 ratio if you only granny ride, but open the throttle wide for a long period , you can say goodbye to the rod end crank bearing.

  • What is the best way to widen the front end on a blaster Terry Preston

  • So I bought a blaster n the guy said he thinks his son used 50:1 you think I should go 32:1 so it's better off think it would run better?

  • The best way is with aftermarket a arms.

    The cheapest is with a widening kit.

  • If his Son used 50:1 and was jetted for that ratio, and you changed to 32:1 , you would run lean and possibly fry the top end.

    Any changes to jetting and oil ratios should be confirmed with a plug chop.

  • Thanks Terry Preston

  • I use a kit with no problems.

  • Idk if it was jetted for 50:1 n the guy said it got done by the guy before him n it was just to fast for his son n they sold it so idk if 50:1 is right

  • Mix at 32:1 and then confirm that the jetting is correct by doing a plug chop.

  • Plug chop like set the plug to a certain gap? N how would I know it's right

  • No, plug chop to see if the jetting is correct..

    Before you make the plug chop run it is important that the float level is correct, the idle is set correctly and there are no air leaks in the system, otherwise the smoke ring may lie about the



    Warm up motor to operating temp.

    Fit new Maker specified plug, ride WOT through the gears and hold WOT in 5th or 6th gear for 10 seconds, or as long as you can safely.

    Switch off the motor and pull in the clutch, apply brakes to come to a stop quickly.

    Take the plug out and replace the old one for the ride home.

    Carefully cut the threaded end off the plug to expose the insulator.

    There should be a smoke ring of a cardboard or biscuit colour around the insulator.

    If it is non existant or a very light colour, you are lean and require a larger main jet.

    If it is a lot darker you are rich and may go down a size in main.

    I prefer to run a little on the darker side, I may loose a little power but it is worth it for the peace of mind that I won't need a rebuild somsoon.You have to get up a reasonable speed so that you can get the motor to pull strongly.

    Then hold it Wide Open Throttle (WOT) for 10 secs or as long as you can.

    The idea is not to get speed but to make it pull strong at full throttle to get onto the main jet circuit. I find I can safely do it on a short run by applying the brakes some.

  • OK I finally got ahold of him the kid that talked to the guy that built it n he said 32:1

  • So now it would pay to do a plug chop to confirm the AFR..
