I just rebuilt my carbs and rejetted them, and now the bike will not start. the floats are set right and the bike is getting gas, but it will not start, i brought the bike to a mechanic and he is having the same problems I had. all i did was take the carbs off, rebuild and jet them and put them back on, what could have gone wrong and how can I get it to run again.
Did you use a DynoJet kit or DIY?
So the carb bowls are filling with gas right?
Did you drill and adjust the pilot jets?
Did you mess with the idle scew?
Have you tried starting with 50% to 100% throttle?
the jet kit was a dynojet kit, the bowls are filling with gas and i did every possible adjustment on the idle screw and mixture screw. turning the throttle didn't help any, all i got was a backfire. I didn't mess with the pilot jets but the mechanic i took the bike to did, and still nothing.
With the airbox off, take a peice of cardboard or such and place it over the carb venturis so you are blocking the intakes. Crank the bike a few times like that and then try a regular start.
Sometimes after cleaning you can get vapor locks or gunk can get blown into carb passages. The hard vacumm the engine pulls on blocked carbs can blow them clear.
Worth a try before you have to strip them down again or pay someone else to unfudge them.
I always jut stick my hand over the carburetors but yeah...every rebuild has required me to do the vacuum trick.
My guess is the fuel and vacuum lines got hooked up wrong. It happened to me. :oops:
the mechanic i took it to said that there is an air leak somewhere in the carbs, my guess is that it is from the top of the carbs, the small o-ring under the cap could be too large and not allowing the cap to seal the carbs completely. thanks for your post, I'll let you know if everything works out.
