Alright I have a buddy that has what he thinks/thought was an 1996 RM250.
He bought some Boyesen Rad valves but they don't have the same bolt pattern and won't fit. He then bought some v force reeds and they have the same bolt pattern as the boyesen ones but neither fit.
Now I have a 99 RM 250 and the valves have the same bolt pattern as mine but his bike is not a 1999 since they look very different.
So we found out that 96-97 have the same reed valve bolt pattern and the 98 is like the 99-00 RMs.
He has the old school forks that compress from the top so we know it is a 96-98.
We also know the power valve on the 96, 98-00 is aluminum and the 97 was steel. His is aluminum so it isn't a 97.
Well the 98 had a flat top piston but his is domed so it can't be a 98.
So what the heck is it?
The only thing I can think of is that the original owner installed a later cylinder like a 99.
Any ideas?
