Just got in off of the firtst ride on my WR and the exhaust was RED hot near the head. Anybody ever come in when its near dark out and see the same thing? This is my first Thumper and any heads up about em would be appreciated. I took the restrictor out of the canister and ground the throttle stop before I ever rode it. Hope that doesn't mean trouble. Also, I ordered a 45 tooth sprocket since I am planning on streeting this bike. Anybody ever run a 45?
