Oh yeah Its almost hitting 50k. Plan on getting the mother of all services done in february.

How many KM on yours?

Itll be good to know how many K's realistically I can get out of this bike If I maintain it reasonably well. I dont think I could bring myself to flick it.

Just under 30000.

It's probably time to do the valve shims on yours. Fun-time-bank-balance-destruction.

Fix the leak first though.

Mine was only going poppity-bang while changing down a gear or two into a corner and doing a lot of revs with a shut throttle. Had the standard can on it at the time.

If you would like some ass-istance I own a honda too.

There is nothing wrong with your bike.
If you think you need to get it looked at take it to amps, they're great.
Just book it in before you turn up this time.

You own two honda's.........

Hurry up and try the iridiums and tell me how they go

Thats if i can be bothered spending another 2 hours changing the buggers...

David Silver's got them for £9 each. His shipping is usually pretty reasonable, too.

This is a technical forum only so no drivel will be tolerated.

Do not complain if you find your posts deleted unless you believe it had technical value.

BTW thanks for reposting my post. Otherwise it would never have made it

Have been told that popping on overrun can be from the mix hitting a hotter than normal exhaust valve (because of leaner mix and more flow) and igniting. Normally on the valve overlap so it burns out into the pipes. I'm no mechanic tho.

Hows that popping going?
