Question for the brain trust....my '81 XT 250 runs very weakly. We've taken the engine completely apart and put in new piston rings and clean and tuned the carb as well as adjusted the timing and still very low power.
Only thing left is to look at the exhaust.
What do you think? Before I do this what do you think the likely hood is that this is the culprit?
When I remove the exhaust....just look for something that's plugging it? There is no spark arrestor at the end and it feels like the exhaust is coming out pretty good right now but that probably doesn't mean anything empirically.
Thanks in advance for your opinions!
