@dtStevie98 Good luck with that, the WR200 Airbox is completely different, not sure it even fits in the frame.

@dtStevie98

Lost but not forgotten, back on a standard Top end, bent Shifter fork and Clutch issues, bent caliper hanger, seized caliper piston, slightly bent yokes as it turns out from long ago, and the Dep Expansion pipe that is only 65% left in existence.

I also dented the tank very badly and cannot pull it out, it's trashed,

And the Power-valve which was 'fully sent'. It blew the remaining pin out the exhaust,, I think as the bottom end didn't grenade itself.

It was doing 80mph in 5th gear and still pulling, so it was mission accomplished.

Full Yeet.

@dtStevie98 Thanks man, might seem older, I do remember having Windows 95..., I've only just finished University,

I do it my way I guess, not the first or the last guy to try this stuff, it's good to see more 2stroke heads out there, the old 125 2 stroke scene is dying out with our generation,

I upload with Flickr on the PC, so cant say,

Welcome aboard G,

Any questions just ask, like you maybe, I modified my DTR just out of interest in engineering and design.

It's like a test mule for just getting in the shed (with beers) and doing something cool.

Mines a tired and wonkey ol example that's had 1000 previous owners, but with so many great memories of it from buying it at 16, and using it in every possible condition and nearly every day for 3 more years. I'll never sell it on,

I've had many ideas and zero time of late to realise them, hopefully we can at-least tell you what not to do from experience.

Enjoy the journey, and don't spend to much money on it!

Why not just buy a 1989 YZ tidler and then build it that way round, Weight the flywheel, lower the compression, Generator, lights, Gear it up?

250 Hours on a top end? Good for a summer,

@Calum It's very inferior to the 3XP-4BF WR200. No Aux boost ports and very tame port timing.

@mhbikesnbits I'm liking the project man, should be sweet! The 3ET lump with some breathing mods will make a nice road going 2stroke. It's a very unstressed engine, plenty of torque down low. Kind of want one as well,

I didn't like the damage to the crankcase and the price of that one, but a good project base, keep us posted.

@Minia Approved.

@Calum Pint sized Unicorns ay,

would have to be a lunatic to spend that much on an old Yamaha... *Cough *Cough
