2002 trx 250 valves

[scorpion 25]

I have a 2002 trx 250 with a possible stuck valve due to bad gas and being sitting without draining the gas. How can I check the valve condition? Is there access to the valve? (like valve cover) How can I unstick the valve?

Thanx for your help

Do a compression or leakdown test.
Should be valve caps or covers on top of the engine to adjust the valves.

You could try to spray some Seafoam on the valve stem and let it drain down between the valve and the stem. It's a good solvent.
Other than that, your going to have to take the head off and clean things up.

Good idea. IMO I would take it off to clean it up. You can check every thing else in there also.
