I have a noise in the top end - now I have built & stripped engines so not a novice. Its a tapping noise. I checked tappets, cam chain & valves - all sound
All bottom end bearings are new. I had the head changed & this noise has evolved.
No piston slap or rod knock. It's ohc.

Anyone got ideas - could I have missed something ?

Piston has been put in right way, dot facing ex outlet so no valve press. Valves checked at tdc. Compression, cam chain tensionor good - its spring loaded please

HELP could it be pre igniting?


Added some spacing, punctuation and the right name of the bike for you. No charge. Wink

Thought I was being helpful, making it easier for folk to read. I didn't have to waste my time on it. Go fuck yourself.

Oh dear, and some people wonder why newbies can get a rough ride.

I've rebuilt a similar engine, and had exactly the same problem! It was quite hard to find the solution, but thank goodness I did because continuing to run it would have been very expensive.

Long shot, but are you sure it's not blowing at the exhaust manifold?

I know this may sound silly but what about if new gaskets on head are thicker so more room when it tdc could that make a sound I would say no just lower compression correct? But compression test spot on
