Cylinder barrel seating

<< < (2/2)

Johnny4428:
This is probably ridiculous to suggest but did you remove the old o rings from cylinder sleeves before fitting new ones?

Trigger:
Jets in upside down ?

PennoK3:
Thanks for the responses.

The restrictors are the right way up and all old seals have been removed.

The new O rings on the bottom of the cylinder liners are a good tight fit but slightly proud of the casting as are the oil seals on the restrictors.

The cylinder block doesn't hit a hard stop but sits about a millimetre or so above the crankcase.   I put the head on and softly tightened (if that makes sense) the first four nuts which closed the gap with no resistance.

Therefore I can only assume its the new O ring seals that are holding the barrel off.

I did this to my K1 a few months ago, and this sounds exactly right to me, and my bike has run just fine with no oil leaks ever since.

Good luck with the rest of the job!

Brian.

Thanks Brian 👍
