AMC forgive me for I have sinned. I am into the second rebuild of my ‘82, in my first rebuild I swapped out used exhaust valves for other used exhaust valves from a spare engine. I lapped them in etc, but I now see from some of your other threads that this was not my smartest move. I got a solid...

Deleted entry, answered my own silly question

Hi First time engine rebuild- I am learning a lot 😝 Full disclosure; I thought I had completed the engine rebuild on my ‘81, until the fact I had zero compression led me to realize I mistimed both cams on installation. I do understand I may have damaged valves, we will see. ( If you can think of...

I've been pussy footing around this job long enough! Engine is out of the frame, head comes off today; finally I can replace the exhaust valve seal that has always leaked. ��

I need to replace shims (probably all of them) on my '82 DOHC. Does anybody know of a place I can order them from? Thanks😎

Thanks (again) amc Much to think about; I have a spare engine which seems to have much better valve clearances- I think I'll get braves and prep the spare head for a swap. I appreciate all your advice, now I have to get my hands dirty :) Oliver Boy

Yes, just did it again. All too tight.

I have a question .....there may not be a good answer .... How can all the valves end up so uniformly tight? I'm currently on the lookout for a set of feeler gauges that measures thinner than .038 mm- otherwise I cant even measure what thickness shims I need to set things straight . I'm...

Thanks amc49 Wish I knew half what you do :)

Strange you should mention that about the #2 exhaust clearance. As we already discussed, all my valve clearances would appear to be 'too tight as well (less than .034mm), except for that one cam which is at .06mm. I'm now really curious to see if my compression test matches yours....

Thanks Jimbonaut. I guess a new set of feeler gauges is first on my list. I'll do a compression check on all the cylinders too; if they are all OK I may leave well alone.... I'm concerned that if my manual is inaccurate regarding the cam lobe orientation, the clearance figures may be unreliable...

All I want to do is check my valve clearances, should be simple- right? Bike was running fine most of last season, but poor starting made me decide to take a look at the valves before timing and carbs... Issue one; when the end of my camshaft is at the position stipulated in my Clymer manual...

Thanks Dave, the compressed air sounds a way better idea than string. Is there any hack you know of, to fabricate a tool for removing the keepers with the head on? amc advocates removing the head -which is undoubtedly the most professional approach-but removing the engine is a whole new world of...

Thanks amc49 :) This job is getting bigger rather than smaller but I am learning a ton and I appreciate your time. Carbstix eh? Right. I'm on it... I have a few hours off today; valves first I am thinking. I used the bike quite a lot this summer, apart from the reluctant starting it runs like a...

Thanks for the quick reply, my post was a bit ambiguous :) What I meant to say was that I intend to access and adjust the idle mixture screws, I read that I would do that by drilling the covering off - just as you suggest- I'm certainly not about to attack my delicate little places with a drill...
