I am a prize spanker, tappet clearances.
« on: 03.02. 2010 11:23 »
Guess the subject says it all.

Have just re-torqued the head after 200 miles ( first re-torque at 30 miles ), reset the tappet clearances, .009 each, yeh yeh I know, I split the difference.

Ran the bike, loss of power and lots of tappet noise.

Was going to post earlier today seeking advice.

Pulled it down, again, to find I have set the LH inlet incorrectly, guessing the push rod must have been sitting on the lip of the rocker when I set it before.

Will be a little more carefull next time.

Yes Orabanda, I'm an idiot  *smile*.

Josh mate - confession is good for the sole, I have to tell you the first time I adjusted tappets (half a century ago) I didn't know the bit about the other side being on compression stroke.  *red*

I know  B44 rider that rode some 400 miles with the pushrod sitting on the shoulder next to the ball ( that it should have been sitting on.
It ran quite well although a bit on the noisy side which is how we found it.
