That should tell you where to go on the tune. If the jetting is off that hould tell you. Is the gas new gas, or has it been sitting mixed for a few weeks? Did you get the carbs new or second hand? Take the carbs apart and clean them up nice. What jets are in the bike now? If you have come so far it makes no sense to quit now. Quote Link to comment Share on other sites More sharing options...

endofitall9 Posted September 26, 2006 Report Share Posted September 26, 2006 A 300 main seems rich to me I'm basically at sea level and I ran a 310 in the stock carbs with the motor in my sig gas mixed 40;1 klotz before that i had fatties and almost exact same mods as you and was at 280 main stock pilots needle 1 down from middle airscrew 2 turns out. What size pilot do you have in there? it jus sounds like your carbs are out of whack nothing big time. I'd say maybe run a 290 needle in middle clip with stock pilot or 27.5 airscrew 2 turns out try that and let us know. Josh Quote Link to comment Share on other sites More sharing options...

addicted Posted September 26, 2006 Report Share Posted September 26, 2006 thanks guys i will try new jetting tommorro , will let you guys know how it works out Could also be electrical. Resistance builds with heat. That could explain why it runs good until it gets hot, Then runs better when it cools.I have had that experience with both stator and coil.It sounds like your jetting it not quite either but that might not be the only thing wrong. You can test the stator and coil using an ohm meter. the specs are in Clymers. Check it while the bike is cold, and then again when it starts to act up.

fastbanshee8 Posted September 26, 2006 Report Share Posted September 26, 2006 Most of the time, hard starting when cold is a sign of a lean pilot circuit. Either the pilot jet is too small, or the air mixture screws are turned out too far. Make sure the tube between the carbs is in place, and isn't split or cracked.

woodro77 Posted September 29, 2006 Author Report Share Posted September 29, 2006 never going to believe this , cleaned carbs and took it for a ride again , 15 minutes and it died again let it cool down ran then died , while sitting there and thinking about just setting it on fire right where it sits , saw that the gas cap vent hose had a kink in it , took it off and it runs like a raped ape, starts on first kick , i cant believe something that stupid drove almost crazy , thanks for all your help guys , has this happened to anyone else ?

blueshee03 Posted September 29, 2006 Report Share Posted September 29, 2006 has this happened to anyone else ? i've seen a clogged tank vent cause it. i took my cap apart and removed the stuff like the little steel ball and such and put it back together.seems to allow for a better gas flow.however you must make sure you have a hose attached to the cap and that its long enough so water don't get in through the vent.
