    Observations on my carb main needles

    I am still fighting an overall low vacuum problem on my 1986 Venture. However I have it running what seems to be good. Synced the carbs using a few pieces of 24 gauge wire in the throttle plates. Then of course curiosity reared its head. Could my main needles be affecting the idle circuits...

    dead short on main wire

    So I fired up the bike at lunch and it died after a minute sitting in the driveway. Saw a little puff of smoke from I don't know where. Needless to say it blew the 30 amp fuse just above the positive terminal on the battery. Pulled sest, tank lid and airbox and can't seem to find anything...

    Yamaha special main jets

    Yamaha special size main jets Don't know if anyone knows or cares but Yamaha makes I guess what would be called half size jets. E.g. between 150 and 152.5. They are used in carbureted snowmobiles. Could be used for fine tuning a Vmax. Here are sizes in the Vmax main jet range and part #'s...

    I recently shotgunned the carbs, pulled and cleaned pilot air jet 1 and pilot air jet 2 on all four carbs, and replaced the idle mixture screw assembly (screw, spring, washer, o-ring) on all four carbs (a couple of the originals had a little corrosion on the outside, so I replaced all four)...

    170 main jet with UFO StreetPro 4-2 and otherwise stock bike?

    I bought an '03 Vmax with the UFO StreetPro 4-2 on it. I've got the carbs apart to clean them because the bike felt and sounded like it was running on three cylinders at 5000+ rpm. (It's fine at light/moderate throttle below 5000.) I noticed the main jets are 170s. I'm concerned those may be...

    Hi, So i just put on UFO exhaust with morley jetkit. I have the air corrector, modified airbox and PCV connected and read on http://www.vmaxoutlaw.com/tech/cv_carb_tuning.htm that you begin with tuning the top end with main jet sizes. The problem is that I can't even get to the top end...
