Will a 94 rm 125 engine fit on a 2000 rm frame?
no
no
They should be close enough to use, might have to trim a little to get an exact fit.
No, the 1990 RM cylinder doesn't fit the 1988 cylinder. The 1988 cylinder is the only year that'll fit on a 1988 motor. This was the first year Suzuki did that. It actually sucks because I have a 1988 RM 125 I've been trying to get a cylinder for. And the 1988 cylinder is the only match. Nothing else would fit.
it should
any 250 2 stroke motor
No, because the rm has different size plastics than the drz
160 psi of nitrogen in the rear shock.
No. You might actually get it to bolt on (doubtful) but 2 stroke pipes are tuned for each bike. A 250 pipe would change your low, mid range and top end power from what you have with a 125 pipe. For optimum power, you might check a Pro Circuit or FMF pipe for an RM 125.
Yes, a 1995 RM 125 motor can fit into a 1990 RM 125 frame, but there may be compatibility issues that need to be addressed, such as mounting points, wiring harness connections, and exhaust alignment. It's essential to check specific measurements and components, as well as potential modifications required for a proper fit. Overall, while it's feasible, careful consideration and adjustments may be necessary for a successful swap.
