Haha, I had been thinking it might be because I don't like to keep my bike tacked out. My bike has Boyesen reeds, Wiseco pistons, and it's piped so i get great low end. So I am just not fully burning all the oil just because i'm not being excessively hard on the bike? Too bad the stuff is so hard to clean off =P Also, I do NOT want to lean it out.. I ride and focus more on snowmobiles, and from that experience, being kinda rich is 10x better than being a TAD lean.
ill just clean the darn oil off.
