Hey guys, I'm having a little trouble and I was wondering if anyone could help. I have a 99 wr400. It has the yz throttle stop, stealth fuel screw, gytr exhaust insert and an 03 yz cam. The cam was recently installed. The thing starts so easily now and runs great. I think it may be a tad rich with the gytr on there, but otherwise it seems fine except for one small issue. It tends to stall when I decellerate quickly. It always starts right back up, and seems to idle fine. It just stalls on me when I come off the throttle suddenly and drop speed and revs quickly. I'm not sure where to start looking. I was thinking that maybe it's just because it's a tad rich. I was going to try re-installing the stock exhaust tip and see what happens. Any suggestions (outside of "do a search") would be greatly appreciated. Thanks. -Jerry

That was my thought too Rich. I plan on fooling with it Sunday to see if that helps. Thanks so much for your reply.
