I have an 86' RM250 and I need a new semi-complete cylinder. I have the power valve and everything I just need the cylinder. My sleeve has a crack in it and I would rather out a new cylinder on then get it resleeved. Anyone know of any sites that sell this item?

 

you might try calling neanderthal cycle salvage.

I have a cylinder from an 88-92 quadracer 250, the 87 is exactly the same as the 86 RM250 with exception of port mapping isn't as agressive on the LT250. The RM cylinder has more top end, than any of the quadracer cylinders, but you can still get a Boysen rad valve for the 88-92 LT250R. My cylinder is .040 over now and it is great shape, maybe needs a hone but it still has the cross hatch marks from the prior bore.
