Hi all,
working on a friends 1985 TRX 250 Fourtrax. From the story I was told it just got back from a service and when they were riding it, it backfired and started smoking excessively (black smoke). It then stopped and wouldn't start again.
I assume it started again after it had cooled, as I was able to start and ride it today. Didn't notice any excessive smoke. I was told it needed a new piston and rings, but I'm not too sure. The compression seems to be okay at 170psi...
Any ideas on what I should be looking at?
I thought the oil may be over full, or the air cleaner cage missing, but it's not either of those issues.
