Bent intake valve #4 WHY ideas !

[CaptonZap]

Gonna look for mid spec, shim if it is on the tight side. I dont have extra shims to shufffle around. Have a 79 SF with 26k on the clock and have not touched it (adjusted) in 2500 miles. Still sounds quiet.

Thats when you want to check them. The gap closes up (gets quieter) as time goes by.
So If I were you, I'd check the clearances.

P.S. Have a couple airhead BMWs', have to check them every oil change. Simple as pie to do them, not like the cover on my XSsssss' . I love all my 2 wheeled children.

Set them to the widest spec. Properly adjusted it sounds like the engine is gonna fly apart but that's where it'll run best.

In case you didn't know, BMW shims are the exact same size as our XS11 shims, so you'll have more options when looking for shims.

Bent Exhaust Valve

I had the exact same experince with one of my XS750s I purchased with 18k miles on it.

Hadn't been run in years.....#2 Exhaust Valve bent slightly...no evidence of collision with piston or intake valve....cam timing correct.....

Eventually I noticed some chewed up links in the cam chain, thankfully as I was still assembling it. I think in my case the cam chain might have worn loose from not being adjusted, then it slipped, and someone put it back. It's all I could guess after looking at the parts.

In your case, we all don't imagine a loose chain at 2200 miles.

We're all looking forward to hearing that it's running again. It's way too beautful to sit in the garage unused.

Colder than normal for this time of year in Michigan

[vedgar]

Running great now

carbs dialed in .Took pics of timing marks as not to second guess myself if something did not seem right. I can look at the pics and at least verify the timing is spot on .
