I Cleaned The Filter and it STILL SPUTTERS!

Recommended Posts

As per a TTR-90( sputtering at high RPM) post I cleaned my filter and the bike still sputters. Anyone have any suggestions. The bike has a FMF pipe and that's it. Could that be causing my problems? I haven't re-jetted yet but have 15 pilot and 95 main just haven't gotten to it yet.

If you haven't opened the air box, then just adding the pipe shouldn't affect your jetting much at all.

Does it rev all the way and THEN sputter? Or does it sputter at a certain throttle position?

Are you sure you're not just hitting the rev limiter? It's supposed to sputter once you max out on the RPMs.

Try cleaning your jets, they could have junk in them, mainly the main jet if its high rev, but also if that doesn't work try running the stock jetting again it may run fine with stock jetting and might not have needed to be jetted.
