    Spark plug soaked in fuel, stuck slider?

    I have a 2000 Max with 73,000 miles on it, stock carbs, jets, and exhaust. For the last 4 months, it has been running as if one or two cylinders are not firing. At a red light, the idle will switch from perfect to a stutter (like a Harley), then back to perfect, within the same red light...

    Puncture in tire.. Replace? Or Plug?

    Hey again, sorry if it seems like I'm hogging the forum. I'll try not to have any further concerns with my max, lol. So low and behold I spotted this on my rear tire. New tire? Or a plug will work ok? I'm kind of paranoid about the idea of a rear tire disintegrating from under me...

    Would this cause a black plug? Dannymax and others

    Well my son was/is having issues with one cylinder breaking up. IE really fat/black sooty plug? Could this be the issue? I would think so but what do I know. That's why I'm asking people who do! What's different/missing from one of the carbs?

    COPS (Coli on Plug) in Australia

    Hi all, Just wondering if anyone in Australia offers the COPS setup for Gen1 Vmax? My 88 max has been playing up lately... the usual kicking, bucking, surging etc.. Did the shotgun and rode it 2 weeks ago, it was running the best it ever has - so much so that at approx. 125km/h decided to...

    Magnetic oil plug

    Anyone using one? If so, what is the total length? Better still - is anyone using an OEM final drive magnetic plug, as their oil sump plug? I have an extra, because of the venture Pumpkin that I purchased a few years ago. Looks to be the same thread diameter and pitch as the oil plug, I...

Now I have cleaned mine thoroughly twice.. every orifice and jet has been cleaned, the float valves were leveled off. I synced my carbs once I put them back on. Now the reason why i...
