thanks for the info. I have the carbs clean, and i richened up the idle mixture according to other threads on here. have not done an external fuel filter though. valves, points and timing are good. i'm just worried they will never run 100% correct becuase i had to drill out the idle mixture...

i have my carbs running decent, but still finicky. it took forever to get it running good, i finally ended up with a bigger main on my right carb than my left and it runs good. right side was running leaner for some reason. the air screw tips broke off and wedged in carbs (common problem for...

hello all, i have a 77' and was wondering how easy it was to convert to the vm34 slide carbs? I've read some threads on here how it's possible to get the jetting to work, but i was curious if the newer carbs bolt right on or if there is some fabrication involved? my carbs are pretty...

thanks psuedomonkey, the banshee swap thread was very informative. i might look into trying that out later this summer. have to get these crappy carbs running good first.

thanks guys

hello all, I wanted to get some opinions on the process of not running a battery and doing kickstart only. my battery is no longer charging while riding, and my electric start has never worked since i bought the bike. I was curious on what the process is like, or if...

So I put in the 45 pilots, and it runs maybe slightly better. But still a little lean unfortunately. Also, one cylinder is def running hotter than the other. What could cause this if there is no air leaks? Point timing, carb syncing? Leaky exhaust? I'd appreciate any feedback Also, some help...

i found some pilots on mike's xs. stock is 42.5, and i ordered a 45. will these pilots work?

really? shit, i always thought the exhaust was stock. one cylinder is lean, the other is rich?? how can you tell? does this mean the carbs need to be balanced? any recommendations on pilot jet sizes and best place to get them?

pretty sure those are stock exhaust (as you can see in the pics) and use the original stock air filter. i even sprayed the layer of foam with super tacky motocross air filter oil ( doesn't drip off the filter over time). is there something with the stock exhaust (baffles?) that could be making...

it idles high, almost like there is an air leak. i tightened all the clamps good, and even packed grease in any areas where an air leak could be possible, so i dont know why it would be idleing high still. i put the picture of the pipe on there also because it looked a little too blue to me and...

hello all. i've been tinkering with my carbs for some time now, as i've had problems with my bike running lean. i did that bonehead move that a bunch of ppl on here have done and broke the tip of my needle air screw off in the hole. i found the smallest drill-bit i could find from a...

hello all, i put a 17 tooth front on with the stock rear and i like it much better. i can now cruise at 65 without straining the motor much. if i'm cruising down back roads or highway, i don't like the motor to feel like it is being strained. and i also like how the motor feels betweetn...

sadly i'm in the same boat. the bike still runs decent, but it's lean and will probably cause damage eventually. i was thinking about finding a custom machine shop to see if they would have some tool to get it out. but i'm also in the market for a new set of carbs so i'd appreciate some...

thanks guys, i'll try out your suggestions. keep your fingers crossed

i posted a thread on here a couple weeks ago about how i over-tightened my air mixture screw and the tip broke off and got wedged down into the carb. i think drewpy or houghmade told me a filed-down nail worked. i finally took everything apart to investigate. i'm assuming the filed down nail...

after how many miles does the engine need to be rebuilt? (piston and rings and whatnot) is it just weather or not the compression is good and it's not burning oil?? mine has almost 14,000 miles on it and was wondering if it's a good idea to do a rebuild over the winter or just leave it.

i just did a ride around the lake i live on. did 112 miles on 1.8 gallons of fuel. thats about 62 miles to the gallon. mine also crackles and pops on one cylinder, so guess i am running lean cause no one else seems to be getting that good of gas milage. i weigh about 180 and i have the really...

What type of gas does everyone use in there bikes? I use the standard stuff at the pump (87 octane) and put a little bit of fuel treatment in the gas to get rid of the 10% ethanol. should i be using the 93 octane? could this be part of my problem? I have to use 93 octane on my motocross bike...

will the air mixture screws being blunt cause the bike to run lean? because the bike runs really good minus the crackling and popping when i let off the gas. either way i'm getting new air mixture screws, but i was just curious and trying to limit other factors that could be causing the...
