#22:   Author: johnny,  Posted: Wed Aug 18, 2010 3:37 pm cleaned all the contacts didnt make a bit of difference. then i went for a ride and by chance met a mechanic who heard what was going on and checked my vacum lines with a propane tank, they were good. he suggested i get the carbs cleaned and stuff inthem replaced since it set so long.the yamaha dealership told me they would do it for $200, sounds better than fair since i work 70 hours a week and dont have time now to learn how to do it. i am still confused on why it only does it (backfires) when it gets hot. so although this isnt solved yet i will probably have it solved in a few weeks. thanks

#23:   Author: totallyredvirago,  Posted: Wed Aug 18, 2010 3:54 pm if you took out the air filter and it ran better (no backfire) and when it was cold it did not backfire... i would say you are running too rich.. have you pulled out the plugs to see how they are burning??....dan

#24:   Author: johnny,  Posted: Thu Aug 19, 2010 6:17 am yeah they were burning right, but it did backfire without airfilter just not as quickly

#25:   Author: johnny,  Posted: Mon Aug 23, 2010 12:59 pm ok got the backfiring to stop! i took the two vacum lines off the mci and put bolts in them. runs great now. thanks for all your help guys.
