the keys in the drawer - what's the metalfor?

You know the mixed emotion you get when you have searched for the keys for 2 hours only to find them in your pocket? Extreme relief at having found them, with a fair bit of grief for the lost time as well as a hint of shame at the stupidity.
Read on friends, and find out how I fixed my vibration issues.




I think I can beat Paul's "total rebuild to fix a cracked exhaust" story.
After changing the crank, bearings, exhaust mounts 3 times, new
flywheel and engine mounts I am pretty sure the engine cowling is
rubbing on the engine side panel.
Just after fiddling with the exhaust mounts one more time, I noticed
the wear marks and rode up and down with the panel off... all was well.
So why did the vibes go away when the exhaust stub was loose you ask?
I'll tell ya.
Because the throttle cable I used to stop the header falling off was
pressing the cooling shroud in and away from the panel.

I'll never be completely sure 'cos I bashed the shit outa the panel to
clear the shroud before testing. Perhaps the bit of inner tube behind
the case to exhaust mount did the trick.

Hmm. Glad it is over anyhow.

Anyway, I now have a perfectly good spare race crank and flywheel to sell.

While we're at it, the SIP performance expansion chamber is back on (see jetting page in links)
A quick blat on the freeway saw an easy cruise at 110 (genuine) with plenty to go. I backed off when the temp soared to 400. I'll change the main jet and see.
