Hi Lads

I am wondering if any of you could identify a cylinder that I have hanging around in my shed. I was given this cylinder when I bought my 1994 RM250. The information I can give you from looking at the cylinder, on the one side it has 29eo and on the back it has 4pa5 and on the cylinder head it has a thermostat housing. I was told it would fit my rm. THANKS

i'm pretty sure that is a Japanese import RMX, due to the brass oil injection nipple on the exhaust port bridge.What size is the exhaust manifold?

thanks for taking the time to look at it. i'll have a look at the size tomorrow

the exhaust manifold is 50mm and the cylinder 67mm hope that helps
