[lb9591]

ok so i think i screwed something up bad. my friend had me cut the silencers off the stock pipes which opened it up alot then i bought a toomy intake and dynojet jet kit, the bike ran fine before i put the jets in there now its a pain in the ass to start usaly bump start it and it runs ok but not great and i can not get it to idle at all any chance this is just tuning error i put 280 main jets in there and the air box is completly removed im allso at about 2000 ft elevation and in california so it gets pretty hot thanks for any help

First of all do a plug chop, if you dont know what that is, AIM is lildeezul, after your plug chop, check your spark plug, if its black, your running to rich, if it is white, your running to lean, you to buy a new sparkplug, for the test to work correctly

OK, lemme get this straight, your running a bike with no silencers?

yeah it was stupid im going to buy some toomy t5's next week. but some guys at a local atv place said it wouldent hurt it i couldent stand the stock pipes, it ran fine before i put an intake on and tryed to rejet it now i cant get it to run right seems like one cylender is hitting harder then the other but i can get it to idle and kick over pretty easy we were messing with the adjustments on the top of the carb and i got 340jets in there now with the washer on the very bottom of the needle some guy that works at yahmaha told me to do that. i am in way over my head on this one if anyone can help im on AIM as lb9591 thanks alot

Put the Toomeys on first, then I assume you have the Toomey 2 into 1 air cleaner system. Put your needle in the middle, 320 mains, 1and a 1/2 turns out on your air screw. Look at your carb slides from the rear of the bike and use the thumb screws on the top of your carbs and get both slides the same height from the bottom. Put new plugs in and start tuning from there.
