Start the strip down...

Remove the flywheel/magneto. The worst part of the job, it pops off like a . The Spanner is used as a brace to lock the flywheel so less hands are needed......

Just got to send the crank and cylinder off now. Big up to Mito Mondo for shipping in parts SOO fast.

The pictures show why i love stroker engines soo much. They're so simple, yet powerful. I think deep-down i love it when it goes bang.....

If you're thinking about doing this to your own engine, it took me 7 hours to strip the bike and get as far as starting to split the crank cases, then another hour or so getting the crank out.

I wish I knew how to do all that. It just looks scary as fook when you have no idea.

My old wmx 250 didnt take too long to strip down which was handy after the ten or so attempts at getting the gearbox right after buying bearings and seals for all of the bottom end (needed them) and when i took the selectors out etc forgot where they went the rest of the engine wasnt too complicated

hope everything goes well

your lucky the crankcases split Vertically and not horizontally like on a KR1S, pain in the ass getting the gear box back together.


if you can,t get hold of any yamabond for the crankcases, blue hycomer or three bond is as good.
