As the title says:

Engine build ...

So I took me donkey to Snozz at C&M Motorcycles @ Ingleburn a few weeks before the 5 hr in @ EC
Thought I’d put that airbox on it I got from Jason Wiblin on it an get it dyno’d before the race meet.
Told Snozz I want it dyno’d with that airbox on it an see what number it’d get.
As it was dyno’d there before in 2016 before we went to PI an he found an extra 5 ponies, from 113hp.
So he chucked it on dyno to see what she’s pullin now.
As it turns out it’s lost just over 9hp (I was wondering why I wasn’t pulling away from other 600s on the straight).
Anyway, he said it may have lost compression, or valves aren’t seating properly anymore.

Ok so let’s do a leak down an compression test.

Turns out it has lost over 1/3 (under 90 psi) of its compression in all cyclinders.

Time for a complete rebuild.

Engine is at Wetty’s place (been a few weeks now) ... stripped to her socks an undies.

Parts ordered ... lots of parts!

That is all ...
