Hi all — Yamaha V-Max

netboard

Hi all,

Have some issues I'd love some help with. The bike runs perfect for the first 5 mins of the day... then when it's warmed up it starts backfiring/misfiring. The exhaust note also changes - sounds like it's dropping a cylinder.

Carbs were overhauled a couple of months ago.

I've pulled the plugs and the number 2 cylinder was wet with fuel... I'm guessing it isn't getting good enough spark.

I've tested the pickup coil, HT coil for 2nd cylinder, HT lead, Stator and regulator/rectifier. Pickup coil, HT coil and HT lead were within specs.

Stator had slightly high resistance - about 0.6ohms on all readings - workshop manual says 0.48 max. Pretty close but a little high. No short to earth though which is good.

R/R seems to be faulty - getting infinite resistance across all diodes?

Bike also is charging at the battery at only 12.9v at all rev ranges. Obviously this is too low.

So..... my questions.... if the R/R is faulty as it seems, could this cause low charge at the battery? I've never had any problem with overcharging, blown fuses/globes etc.

Also... if the R/R does indeed cause my low charge problem, could this be the cause of my problems with backfire/misfiring/dropping a cylinder?

I'm confused because I don't see how this would only happen when hot, and only seem to affect no. 2 cylinder?

Maybe I am missing something.

Expert advice appreciated!

Sorry for the long post :)

              Photos from Isaiah Gibbs's post — Yamaha V-Max

              I bought a 91 VMAX that had been worked on by Cycle Dynamics in New Orleans. The shop owner said this bike dipped into the 9's in the quarter. It had all sorts of work done to it, and was informed of it when I was on the phone. I called to get a quote on the clutch to be fixed. Fluid was on the bike and the lever as floppy as can be.

              Bike is now a flood victim in Louisiana from back in August.

              Anyways, anyone here run these carbs?
