Thanks man, this video was really helpful. I just got a 1985 CBX 250, which has the same engine. I've only ever worked on car engines before, so I would not have guessed that the timing mark was under that top cover!
Being a 4-stroke engine, it is not enough to align the TDC mark as shown, you have to make sure that all the valves are closed. You would know if it's the true TDC by slowly turning the crank back and forth with the T mark aligned. The valves should not move, if they do then turn the crank one full revolution.
I'm glad you added this comment. The piston has to be at the top of the compression stroke NOT the exhaust stroke or the valves will be under load and not loose.
Thanks for the helful video!! I finished my valve adjustment with the help of your video and the bike's manual and now my bike's exhasut valves click when I turn it on. Like rapid clicking when it opens and closes. I did loosen the decompressor cable but I put it back on and followed the manual for free play in it. Would anybody have any ideas on why my exhaust valves still click?
On my '97 xr I had oil pour out of the lower cover (where you turn the engine over). When I worked on my 1993 xr no oil came out of this cover. Which one should have had oil in it or is should the '97 have oil and not the '93?

Nice, Just picked up a 96 xr250l with some noisy valves. This made things a lot easier than digging through the clymer manual.
good tip on bending the feeler gauge / shim stock. thanks for uploading
This video is adequate for people with average mechanical abilities. 👍

A+ comment
That's wht I was gonna say this guy is fucking alot of people
My valves had 1/8 " of slop on all 4 valves. I tightened them to the specs 004 005 and no change in performance or sound? Any suggestions

How long did it take for you to complete adjustment start to finish?

My 2001 also had oil on the covers
Id say it was over filled
Great info
