    Miss when cold runs well when hot?

    Ok, So I have a 1989 full power bike with 20k kms. It starts right up no issues, but runs very rough, pooping etc And the left rear cylinder is def not firing as the exhaust header is cold. After I take off and run for maybe 5 mins, the bike comes good and runs great, pulls like a train...

    Runs bad once hot

    Alright guys I'm out of ideas. I'm putting my friends 99 back into service after a long storage, and I've been through pretty much the whole bike. I overhauled the carbs, put in a new fuel pump and filter, cleaned all chassis grounds, eliminated the stator plug, have the regulator-rectifier...

    '90 Vmax. Runs good but needs love. $2000obo

    I have a '90 with about 42k on it. Stock except for a Corbin seat. I have the stock pipes (great condition) but right now it's wearing a pair of empty cans. Sounds great but it's LOUD! Comes with these parts (not on bike): pair of gold dot front caliper and front disks to go with them. Adapter...

    Runs like crap and dies---1998 VMAX

    Hey guys, Please post up if you have some answers. As I am still on a steep learning curve, I am wanting to know what could have happened internally to the fuel delivery system. Happens that the bike was leaned pretty far down on the right side. After this, it ran ok for a few miles then...

    Bikes runs but front left cylinder is not firing

    I got my bike up and running finally but it ran rather rough and I felt the exhaust and the front left is dead cold. Did a compression test and it started at 90 psi and finished at 150 psi so I assume the issue is not mechanical. The plug was not wet and looked clean. I swapped over the plug...

    Dear Fellow Rider, My name is Gee. Ive recently joined to learn more about my new toy from fellow members. I got the bike a month ago, and it would bog down after 5000 or so rpm. Up tp about 4000 it had the power to burn rubber.... Things Ive done in order. 1. Checked battery off...

    runs like crap

    I sure hope someone can point me in the right direction. I have shotgunned twice, broke down carb completly and did through cleaning on all jets and jet block, 1/4 can seafoam and new fuel filter and still getting the same outcome. The bike sputters at low speed, some backfiring, very low idle...

    runs on 2 cyls @ low revs/idle; tach goes dead.

    just started running on 2 cylinders when at idle, and tach goes dead. I twist the throttle ever so slightly, and I can feel when all 4 cylinders start firing at about 1150 rpm, and the tach simultaneously jumps to life. very hard to start now, if it'll start at all. when I do get it to start, I...

    Stage 7 with OEM Exhaust - Runs a Bit Off...

    I finally got Mr Max for the very first time since getting him 4 months ago. The bike came with a Stage 7 kit installed and full UFO exhaust. I sold the UFO exhaust because we have strict noise laws here. So the current setup is Stage 7 and OEM exhaust. The bike starts and idles fine, but...

    Stock Vmax runs TX 337

    This video is a little long, so plan about 8 minutes. Charlie took off first, it took me a little while to catch him. I had to pass 3 bikes, and there weren't any good places to pass. He waited for someone which turned out to be me and we started flying!!!! ENJOY...

    Old Style Fuel Pump Runs Too Much, Too Often

    I've been fighting this on my 89 for some time. When I turn the key on, sometimes the fuel pump runs for the given 5 seconds as the older model Max's will. Sometimes it will go click, click and be done. Once the engine is at operating temp, I can turn the key on and off a dozen times and it...
