WANTED Cr250r crankcase

[Bigmac]

There are lots of options!! Lol
I do miss my banshee days. Was one of the first In the Coos Bay Area with a set of the cheetah cub cylinders. Bought them for a 4 mil, and had Dan Hull at A&S racing port the cylinders. 6” swing arm was definitely not long enough. Had it dynotuned at 96 hp back then. Probably about 15 years ago.

Yep! Been there! I got my cubs 15+ years ago too, 7mm and had a 6 over too with 10 paddle ultralights, it was into a wheelie before the power hit, was kinda stupid that way, and kinda slow! Lol, +14 now and still an issue! Dan is a good builder!

Would you be willing to sell that motor or know a place I should keep my eyes on for a bottom end?

I have to look, I have another cr350 cylinder, it was a 330, then was sleeved to 350, I bought it that way, it is an 80mm bore and has a built trx head. Also might have a damaged set of cr cases 92-01, have to look for those.

Also have a ported 01 cylinder head and piston

I have too dig through some boxes on the cases. But the jugs were in my garage

There are some stupid cheep cases on eBay, 92-01, slightly damaged for 150

Did a little research for you, look like 84-91 cases will fit the trx cylinder, with 84 having an odd case and powervalve that makes the case messy, but the cylinder will fit, the 85-86 is ideal, 87-89 will fit but has a boost port into the intake that is not ideal, but it fits, and the 90-91 looks good too, the k+s base gasket fits 85-91, just an FYI
