When you adjust the valves, you're really just adjusting the play in the rocker arm. You can usually just bend the feeler gauge and it should slide in place. Check your manual and try to use the smallest recommended size. Make sure that the valve springs are not being pushed down, there should...

You're a brave man takin that old bike out on 94. I'm in Indiana right over the Michigan line, and I'd rather not go 80 mph on a bike that's older than me... Hope you feel better man.

You're a brave man takin that old bike out on 94. I'm in Indiana right over the Michigan line, I've never taken a ride on 94, screw that. Hope you feel better man.

Had a look through the spark plug hole and could see that I had the intake valve hitting a piston =/ fixed it and now its perfect. Gonna throw some yamabond on there and bolt her back up. Just took apart the carbs and cleaned em, should have it running by tomorrow =D

Well, when i was adjusting the timing it bunched up and locked up but I reversed the bolt by the stator and got it to free up. When I put the tensioner back on it was looking good. Having a mechanic friend come to look at it today again so I'll let you all know what the problem is. The only...

Hmm.. Bike is in neutral, even turning the 17mm bolt though it wouldn't spin. Laid the cam in the right way, found timing marks, got everything lined up, and blades are in correctly, there's no play in the chain.. so I really don't know what it could be. I'm gonna check it out tomorrow in the...

Part 1 from this thread http://www.xs400.com/forum/showthread.php?t=4503 Engine, clutch and transmission.

I did not set the timing correctly at first, but I had a mechanic help me line it up. When I tightened up the bolts I did it evenly in a diagonal pattern.. umm.. I tried turning it over by pushing the kick start with my hand, and by the bolt. And the oil seal is on the left side that sits in...

Well, my cousin had one of his mechanic buddies stop over, and it turns out I had cam guide and chain tensioner blades in backwards :banghead: But still when I put the cam cover back on she won't turn over. Valves are moving, and bike ran good before head gasket went loose, so don't know if it...

When I bolted it down it would get stuck at a certain point. So I took off the bolts and just laid the cover on there and rotated it until it popped up. Does it look like I did anything wrong? Is there anything I should be doing? Thanks.

Thanks, I got it. Now it just seems like the cam cover won't fit on top. The cam cant move, it's like i did something wrong. If I can I'll take a picture.

I found it. No worries.. Only thing now is I don't I put the cam back in right or something.. I tried putting the cam cover back on and I can't manually crank it once it's tightened down.. My dumbass also snapped one of the bolts on the timing chain tensioner.. doh

Hello there, first post. I just picked up a 79 Yamaha XS 400. It had a blown head gasket, so I've spent the past few days tearing everything down. I changed the gasket and started to put her back together, and realized i was missing a washer for one of the acorn nuts. If it's fallen into where...
