valve clearances

I found the plunger on the tensioner was right at 15/16 to one inch out when my cam chain is tight (from the housing not the gasket)........ if its one inch and 5/16 or a hair more out you've pretty much reached its limit........ If your readings are thousands on the cam clearances your ok for a while.

Not sure which number is mm?

Are these ok clearances for my 78 kz650?
I'm stumped.

.008 inch = .203mm

Ok ok. Well in my manual it says the valves need to be at 0.15mm

Based on the measurements above and on the info at the link, #3 intake and #1 exhaust are out of spec. The rest seem to be ok.

Yeah I agree. I don't look forward to taking out the cams

Once done you're good to go for 3-4000 miles. Did you get your cam timing issue worked out? When you said it had jumped, I thought bent valves. :ohmy:

Well I checked the markings on the cam shafts with the timing Mark T on the timing adjuster the T is a little off from the cam shafts. The cam chain pin count of 36 seems to be correct I might just have to realign it all again. Wtf. When I saw it skipping, I tightened the cam adjuster and it stopped but I don't get how it came loose.

You'd better find the problem or all hell can break loose.

Before I took it apart yesterday it ran fine no noises or anything. Just when I rotated it with the wrench it was skipping in the middle sprocket

You mean on the crank sprocket? Frightening.
