XR250 Tornado valve clearance check... help
Hello, I'm hoping to find advice/help for checking the valve clearances on my Tornado 250. I've got the feeler gauges ready to go, and I think it's an easy procedure. But I've never done it, and I can't find any information... except I think the clearances should be:
intake .12mm
exhaust .14mm (or .16mm?)
The "certified Honda mechanic" (at a brand new dealership where I live in SE mexico) says he'll just "listen to the engine". I talked to him about using feeler gauges to check the valve clearances and he looked at me like I'm nuts. I think he doesn't want to, or maybe doesn't know how to check the valve clearances properly.
I'd do it myself if I could find any information on how to do it. Any help is appreciated, thanks!
Steven
ps- my tornado has 18.000 km and runs pretty good. The valves have never been checked.
