    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Hi guys, my question is about my '78 GS550E. From your experience, if intake cam is one pin off since there are 19 pins between the 2 and 3 marks, would that affect the engine a lot and warrant the tensioner/cam chain/cam shaft procedure? Thanks!
 
Thanks Suzuki mad! That bad? Bought it in April part basket case for 300. Never started or rode it yet. Since then, I cleaned and rebuilt the carbs and clutch, checked valve clearance and replaced some shims,replaced petcock with new manual one, and new air filter. PO, who got it to make a racer out of it, said he could not even make it idle right and there is cam chain noise.Bike sat in a shed for years. Now I can suspect that the cam chain timing might be the culprit for the rough running and noise.

All I can say is my cam timing is off on both exhaust and intake. Somehow, the bike did run like this. I don't know if it was some bizarre synergy of the degrees that each cam was off or what.

I also can't say for sure it didn't do some kind of damage. I'm in the process of correcting it so we'll see what kind of difference it makes.

Enough with the negative vibes! If a valve have been hitting a piston, you would have noticed it long ago. Play with cam chain tensioner before you reinstall it, so you fully understand how it works when correctly installed- note that sliding shaft (once unlocked) can ONLY move out and not in.

Ha - wasn't trying to be negative. Just not confident enough to say everything was running great with the mis-timed cams. As it's my first bike, I get excited just when it moves forward! :)
