Hello,
I have a XR100 in a YSR50 chassis that I use for road-racing on a local kart track. At the last race, we noticed that the bike smokes quite a bit when I'm off-throttle, but nothing noticeable under power. The bike seems to have the same power that it's always had. As far as setup, the motor is a stock 2000 with a FMF pipe, UNI clamp-on foam filter, 38 or 35 pilot, 102 main and the needle is at the 2nd notch from the bottom(1 lower than stock). Also, I'm in central Ohio.
I'm assuming something needs replaced, but what: rings, valve seals,....
I hope someone has experienced this before and can show me the right direction to go.
Forgive me if this has been covered before. I searched some and didn't find anything that I thought matched this.

High intake vacuum on decel is often the intake guide/seal.
