Tight Clearances

[Azazel]

Hey everyone - could do with a bit of advise please....

I have just check the clearances on me L1 due to a 'tapping' sound - I found that most of the clearances are tight.
The worst is #2 inlet (0.08) which should be between .12 - .17. Could this be causing the tapping? All of the Shims are between 2.75 and 2.90.

It only taps after about 4.5K revs.

I notices my cam chain tensioner rod is fully out so tensioner will need replacing - could this be something to do with it?

Many thanks in advance

sounds more like cam chain or guides to me, fully extended tensioner says to me that the chain is worn, but yes u do need to adjust the clearances into spec but tight clearances wont be noisey.

Needing a complete overhaul there , sounds like you caught it in time though !

Tight is bad But good for HP So most never notice as your bike goes like fook to self destruction !

Camchain , guides , tensioner and shims - get them replaced and set up again.

Do a check again in 3,000 miles time and see if your clearances are tightening up again - take acurate measurements not just within clearance.

If your motor has a tendency to tighten the gap you need to monitor more - loose is good as power goes down and you notice.

If your setting up a race engine you want as tight as possible - these are stripped regular so cause no issue.

MM!
