brian r Posted May 7, 2004 Report Share Posted May 7, 2004 The TL seems to be getting too hot. What do you all think? Timing too far retarded? Mix too lean? BTW, it's old and wore out. It gets so hot that it pings and touching the points cover will burn you. Quote Link to comment Share on other sites More sharing options...
kevin j Posted May 7, 2004 Report Share Posted May 7, 2004 How old and worn out? If piston clearances are too great, the pistons don't cool properly. This leads to hot piston top and preignition/detonation,. More important in two strokes. Doesn't usually mean hotter running oil in the sump though. If there is excessive blowby, minimal compression, it will run hot, but seizure is not far behind then. My bet is restricted exhaust, lean mixture, or timing off. either R or Adv will do it. Do you have enough oil in the crankcase? Mud in the fins, dragging brakes, the obvious stuff? k Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted May 8, 2004 Report Share Posted May 8, 2004 Check for air leaks at intake. What color is the plug? Quote Link to comment Share on other sites More sharing options...
sherpa Posted May 9, 2004 Report Share Posted May 9, 2004 (edited) Brian R, Check the top end for oil, some of the early TL's had faulty oil pumps. The little gears in the pump would crack and the pump would fail. Oil would not get to the top end and eventually it would sieze. The first symptom would be over heating. Ive seen two bikes that this happened to. Granted, this was when they first came out whith the bikes and it is unlikely that yours could suffer from this problem. but I thought I would mention it anyway. Good luck!!

brian r Posted May 11, 2004 Author Report Share Posted May 11, 2004 Kevin, I bet your right. The exhaust is original. Hopefully I can get a Sammy Miller one soon. Quote Link to comment Share on other sites More sharing options...
kevin j Posted May 12, 2004 Report Share Posted May 12, 2004 If it sat for a while it might have lots of rust in the insides. The only benefit to two stoke mung slime is that it keeps the inners from rusting. 4 strokes often get rust in when sotred a long time.
