<![CDATA[200cc crankcase conversion]]>Is there anyone here who could or knows someone that’d one day bore it may cases to accept WR200 3xp top end and crank? And what they’d charge for it?

It’s been something I’ve been curious about ever since seeing @Louis-DT-WR build his engine

@Stevie-Wonder Pretty sure he documented it all on this website...

Ye I know @Calum I’ve re-reading it but all the photos are now gone 😞

@Challenger I’ve got a v force blaster 200 Reed cage that should help right ?

And thanks @scrimsmustang! If I’d been known it was simple earlier I think I’d have already done it 😂

Excusing the powervalve blade itself do you need the WR’s Servo motor, pulleys and housing etc

And I presume you need either a 200cdi or a Zeely/Ignitech programmable ignition too

No you can use a 125 servo and a 125 CDI with no problems at all

He changed his YouTube channel name when he built the cb750 but here's the link to his video which is a montage of all the photos of the conversion.

What county/ town you at? It’d be nice to know a good engineer. They’ve all but disappeared down my way...

It's nothing cases just need a couple of mm taking off to accept the 200 crankshaft. Any small local engineering shop will do it for around 30 quid. Top end just drops straight on
