Its an cast iron sleeve. The grinding of the sleeve is only in one direction. I have to give the cylinder away to get a clear 45° cross cut.

I payed 600 Euro for the Engine and 140 Euro for the shipping. I think its okay. To buy a new piston because of the new cross cut is sad...what an idiot who runned the engine the first one or thwo miles without...

Ah right. Normally the cylinder on the WR200 is plated though isnt it?

£460 roughly including postage. Seems like a good deal for a fully rebuilt engine! Well done!

610 Pound Its 600 Euro + 140 Euro Postage ;)

I Messured the timings of the cylinder

Transferports : 145°
Boostports : 192°
Exhaustport : 218°

They are very long, aren't they?

Ah yeah i forgot to add the postage lol. Sounds about fair now id say.

There is mid-late 90's 2 stroke wr250. Essentially a YZ250 with a wide ratio gearbox ( which is what WR stands for). A similar story as the wr200. not hugely produced or popular at the time.

Is that all? I would have thought you'd get more than that from a WR200 engine, I don't think I'll be too far behind you when I get my Hybrid on a dyno.

Nev I hear the true monster is those 230 lanzas. Much more power than those wr200's

Like i write in my blog over 40 PS were possible but i like to ride the engine like a "all day ride" on the street too. It should not crash after a few miles.
Original power on paper of wr 200 is 35 ps at crank... but this is on paper... normal will be 32 to 33 PS. I got 5 PS more than stock with wide power band. Im happy!

The next engine i build up will be a higher Power version, keep eyes up!

I reckon I'll see how I go on with the DEP at the minute, but my lad is after the DEP off the Black bike, so then Black bike will have the new DEP off the Red hybrid, then I'll get one of these misters
http://www.tmukonline.net/menu/27/Scalvini%20Exhausts/28/Scalvini%20TM/

On the Red hybrid

I still have this trump card to play,

once I set the choke cable to the handlebars, it runs lean otherwise

 Nice results. Sounds like it will be  very nice, smooth bike to ride! 280bhp per tonne sounds nice too :) Look forward to getting my WR on the road :)

Bring on the summer!

The irony is that I didnt understand what you were saying so googled it to find out. When nothing came up I guessed you meant to say that you didnt understand.

yeah, front wheel slides away i don't know why it was really stupid!

Was not the only crash happened. At the end of the Second day i wanted to clamp up a hill and .... yeah it goes wrong. My friend filmed it with his go pro, i will get the video soon!

Now the FMF Pipe has a little dent. But im glad thats not too bad. Only on the left side and not in the resonance zone
