This bike is an American import into Australia. I purchased it 4 months ago, sight unseen, from a guy who imports and sells bikes in AU. So after a while i've been tinkering away trying to figure out what was causing the oil to burn / drop / disappear. Eventually I decided that I would take the engine out during our tropical wet season.
After running hotter plugs it wasn't too bad, I had tightened up the tappet clearance to stop the occasional rattle but was still fouling plugs.
Farted around with mixture trying to lean it out but was still fouling plugs and not running as sweet as I would have thought.
So, first picture....
This was after a polish and before any major work....
The start of it all, re did the tappets again and this made nil difference, so I have a friend who has a motor cycle workshop that let me use a space for a few days.....wet season had started (it rained for a few days so it was on)
Engine out, keep a close eye on the color of the left side piston and head coming up....
Cylinder head
Pistons....
More.....
Virgin engine, all gaskets are from new, you can tell if someone has been in before, and this engine hasn't been out or had the head or barrels off before!
Clean up, media blasted the pistons to get the crap off.....
Thought I would blast the intake air boxes as well, made new caskets for them and gave them a few coats of flat black....
One thing that irritated me was cleaning the casket cement off the sump, it takes bloody hours of scraping, only morons use gasket cement on sumps!
So, that's where I am up to, have new cam chain, seals, cam chain tensioner and guide (old one was collecting in the sump in little pieces) rings, head has been shaved, valves re seated and re faced.....keep an eye out as I will be chucking this lot back together soon.....
