I have a 2000 sxr 700, ~6300 miles. Here's problem #1: the sled idles great and takes off slowly good. It's when I let off the throttle. If I let off the throttle and get back on it, the sled wants to hesitate and backfire, when I know it is going to backfire I let the sled go back to idle and it wants to die unless I play with the throttle or choke. If it stays running, it will idle like nothing happened. Any ideas?
I think it is a fuel issue, because it started to do this late in the season two years ago (I didn't ride this one last year). I cleaned the carbs once and it didn't make a difference. Pulled the carbs again tonight to adjust and clean the fuel/air screws, and I can't get one of them out!! The screw won't turn in or out. I don't want to strip the screw. I need some ideas on how to loosen the screw up to get it out and clean it. Any tips? All help appreciated!!

drip some oil on needle ,let soak in. buy a can or 5 of carb cleaner. take carb all apart and start spraying in all passages. use air too. seem that may break it loose. get the perfect size screwdriver before ya get mid evil on it. o ya unhook tors and test.

X2 on the above especially the tors. Most common trigger for tors is throttle cable is to tight. Bypass to check then figure out whats triggering. Leaving it bypassed sled may run away with out you!

The throttle cable has been loosened, I initially did that when the symptoms started. Once I finish cleaning the carbs I will disconnect the TORS and see what happens. I am hoping the fix is this easy! I will report back with what I find.

Update: took the carbs to a local shop to see about the air screw, the threads are all junked up! So the screw is not coming out! Plan is to finish cleaning carbs a second time and try again.

Update: cleaned the carbs again, adjusted two if the three fuel/air screws, checked and adjusted floats, fresh premium gas with a splash of SeaFoam, bypassed the TORS. I ran it on the stand and it seems to be running much better! Hopefully I can find time tomorrow to run it on the snow, for the first time in nearly two seasons. Hope all goes well!
