bansheecowboy Posted January 28, 2007 Report Posted January 28, 2007 hey guys, i am new to your site, but got a ? for all of your banshee riders. i have a 02 banshee, and just move acrossed my state and whent up 1500 ft in evl. i whent from a 230 main jet to a 220 as the yamaha dealer told me to. it ran great for the first part of my ride then after lunch it soulded like it was flooding and just ran like complet sh!t. i got the shee home and pulled the plugs thinking i foulded them and just for the fun of it i kicked it over a few time and found out the one clyider had good compresion but the other had almost nothing. i have maybe 100 hours on it and not very many are really hard riding but what do you guys think could be the problem????

Animalman294 Posted January 28, 2007 Report Posted January 28, 2007 Well first off welcome to the HQ. Did you do a plug chop before you changed the jets? Then after the stealer told you to change the jets did you check them then too? Quote
itsaripper Posted January 29, 2007 Report Posted January 29, 2007 Check the reeds, one may have broken clear off Quote
trex banshee Posted January 29, 2007 Report Posted January 29, 2007 i take it you have stock pipes?? I hope you do cause if you have pipes and a 230 main, your problem is probably a hole in the piston, running too lean. you need to list everything that has been done to your bike, so we can help you more.

bansheecowboy Posted January 29, 2007 Author Report Posted January 29, 2007 i have wiseco piston but they are the stock size, i have reeds but cant remember what kind, dmc exhaust, twin air filter. and that is it for motor mods. i took the top end apart today and the right piston has a small gouge on the side and bunch of dents and crap on the top of the dome. also the cylinder is a little scratched. so i think i found my problem. are any of you guys from the rapid city area to tell me were i can get my banshee machined so i can get the scratches out.

trex banshee Posted January 29, 2007 Report Posted January 29, 2007 well that sucks but atleast you found your problem, before you put it back together you need to put bigger jets in it to prevent this from happening again. Quote
bansheecowboy Posted January 29, 2007 Author Report Posted January 29, 2007 can any of your guys give me any idea what size jet i would need at 3200Ft. the 230 jet is what the guy who own the shee befor me had in it and he raced it so i thought that would be right?? Quote
gregbowler Posted January 29, 2007 Report Posted January 29, 2007 I'd say minimum 300 main for pipes and pods at that alt. Whats the temp there? Quote
