Contact Noleens. I looked a couple months ago and hey sell various parts for the 360 kit, and I bet they'd have a lot of answers

The piston is from the '79 400, so you can get replacements on eBay cheaper than Noleen. Can't remember what the rod is from, but it not the stock 250 IIRC. It uses the archaic reed valve, I would either get the stock ported or see if you can locate an older Rad Valve or one of the reed blocks FMF used to make.

I have had two of these kits. Sold a complete one, motor and all, and have another for a project. Don't expect a bit power boost, you get mostly torque. They also need more flywheel than the stock 250, a good balance job, and a proper pipe.

Noleen made pipes specifically for this conversion, these are even more rare than the kits. I plan on putting my kit on a WR bottom end to take advantage of the greater torque for the wide-ratio gear set and the extra weight of the flywheel on the WR. I have a Noleen pipe also, but again, I recommend you approach this as a cool rare item rather than as a fire breathing, Mugen-type deal.

Would be cool when you get it done. There are a couple of super-sharp '88-92 YZ360 projects around.

Mossbarger makes a replacement reed block. The 360 kit uses the same reed block as the '85?-'89? YZ250. It's about the same as the Noleen stock YZ250 replacement in terms of cost and it flows better. I'd use a PWK carb with all this, too.
