The top end was cleaned up by a shop, valves cleaned and lapped (one replaced). The cylinder walls were bored only to rid it of the hourglass...
The valves were lapped and springs adjusted by a qualified shop, and correctly shimmed by myself.
Hoping it's not the issue - not...
I'll take a look this week at it.
From what I remember it was spotless, looked like it came right out of the factory.
I haven't really revved it...
Not that I can see.
I'll talk to my bike guy and see if he has a jet kit in stock - I'll see if it makes a difference!
Thanks again for you help.
Trying to get around the spam filter to post this, doesn't seem to like my jpg or imgur links.
Wondering if you can help with my problem.
I have a '82 which I built into a cafe-racer, I attached a photo for anyone interested.
I've been on the lookout for a headlight fairing cafe racer style for my 82' XJ550R Seca, to complete my cafe racer build.
