Hey I am new to all this 4-stroke stuff,so bear with me if you can,I just picked up a dealer demo xr100 for my son,he's 11 and is loving every minute of it! The questions are as follows,what's causing the plug to carbon to fowl?it's new with about 8-10 hours on it? And what is a good aftermarket pipe for this bike? THX!
