Bike studdering when cruising?

3 posts in this topic

Hi i recently jetted my bike, did the AIS, adjustable fuel screw and put YZ exhaust on. Couldn't be happier with the performance gains so i must have done something right since that was my first time jetting a carb. The bike is responsive throughout the throttle range but when i am cruising at a consistant speed around mid-high rpm range the bike starts to stutter. I am guessing this has something to do with the jetting. If anyone has had the same problem and could help me out it would be greatly appreciated.

Throttle Position Sensor (TPS). Search how to adjust the TPS and the studder should go away. Not many (if any) notice the TPS being poorly adjusted from the factory while on the trail, but it is VERY common when the bikes are on the road at constant speed.

Simply unplug the tps and see if problem is still there. I have a very noticeable difference in mine when unplugged. Nice and smooth, but seems to lose some of the punch. :cry:

I have yet to re-calibrate mine. This is something I plan on doing very soon.
