Thanks Rick for the PM. I talked to one of our group
gurus and was told that your 300 cylinder will not
fit my 1998 EC250 bottom end with out some
machine work. Oh well.
Good luck on the sale.

Oh really. I wonder whats up with that? Mine was converted to a 250 from 300 and my friend Gary's started life as a 250 and ended up a 300. He had the conversion done by gofasters when he bought the bike new in 06 from them, I can't see why it would'nt work on yours. would you care to share some insight? B.T.W. both bikes run great.
 
98 EC250 to 300 swap

I saw your post stating that the 300 cylinder will not fit on the 98 cases .I just checked it out on a 98 bottom end I bought so I could build myself a counter-balanced 300 .The 2001 300 cylinder slides right down onto & into the 98 cases with no apparent clearance problem .I wonder what they think the problem is ?
 
hmmm. I better keep an eye on this thread.
I was just reporting what I was told by a good
friend and long time GasGas dealer that the
300 cylinder would not fit a 1998 EC250 bottom.
BTW, WideBear. What year is the 300 cylinder from?
& Sierra Gaser: What year cylinder did you use?
