Were the cylinders bored out already?
There looks to be a fair bit of crosshatch visible on the walls.
I would look to make sure the edges of the ports are chamfered properly, specifically in line with those score marks.

Thanks Farmer.

The pistons measure 50mm so I think they are stock. The bores do look like they've been honed and the rings are grooved as well. I'll be paying attention to the ports and cleaning everything. Happily, my biker neighbour has years of twostroke experience :D

Anyhoo...the engine wedged in place quite nicely I reckon.



The front mounts look like they'll line up with the brackets (or make new), either way, close enough :)



The rear engine mount should align with the Honda spigot.



Liking how it sits and fills the space without crowding it.



Thanx for checking in.

A few parts are winging their way to me :D

Including the rear axle spindle complete with adjusters, T pieces and caliper mount
for a bargain 15 ($20), hope it fits?



'Hope it fits' is a default on this project haha! So far so good.

Shopping list:

Clutch plates
Front axle spindle - Honda NSR to suit the wheel and I think the forks?
Piston/gudgeon pin circlips

Hope to pop the barrel and head into the machine shop for a hone and skim.

Just got off the 'phone to JT's in Swansea they have most of what I will need for the engine rebuild, great prices as well....mostly better than Ebay too. IE: 20 for a stk piston and rings inc VAT.

The exhaust looks like it will be running quite close to the front frame downtube, I hope it doesn't damage the frame paint.

I did wonder how they would clear, but the image is deceptive as it makes the tube to be much fatter than it is. There's clearance, the same as the 200 frame had a single downtube before cradling under the engine. If heat is a problem, I can always fab a heatshield or wrap the downpipe in white wrap.

Interestingly, I may make my own zorst and use VW type1 exhaust J tubes as the down/up pipe before an expansion chamber system.

Rear axle spindle, adjusters and caliper mount arrived...all good, just needs a good clean up.



Q: Can I use racing wet tyres on the road? It appears some are and some aren't, is that correct, does it vary by make/model?

I would assume you would get really shit mileage out of them.

Why does it need racing tires for a 200 a/c ? You want better grip with a narrower tire?

Can't wait to see this wee beasty finished btw
