Am stuck in Germany with my bike.

Was motoring comfortably at 50mph when I lost power and almost stalled.

I obviously pulled over and it kept running BUT with quite a loud rattle/knock coming in at a faster engine revs. I first thought it was a big end, but later presuumed was a sticking valve.

It's quiet at 20 then it kicks in.

Got the rear head off so far as I believed it to be from there.

Question should both timing marks on each cylinder be at top at the same time or should they be opposite for each cylinder.

I am sure I can work it out in time, but am still wotking on it outside a friends flat.

So far no obvious damage to rear cylinder cam shaft or valves and about to remove the front head to check

I also thought it might be the drive wheel of the timing chain.

Anyone had similar experience?

forget the above have found the big ends are gone.

Did you manage to repair it? Ive got the same noise on my XVS 125, can you offer any advice?
