Need some feedback on the feasibility of replacing the entire motor in my '05 DE200 with an '05 or '06 300 motor. My understanding is that the bottom end on both engines are identical, as are the radiators and hoses.
Will the mounting points in the frame be the same on both bikes?
Obviously, I'm aware the the pipe / silencer would be different and likely the CDI box as well. How about the secondary ignition coil? Will the pipe brackets be the same? Have I overlooked anything?

Why do I want to do this? The bike I've got is set-up with Ohlins at both ends (custom valved by LTR for the current rider). It also has the shoulderless Dirt Star rims. I doubt I could get my hands on a comparable 300 - and would probably still be looking at a full set-up routine before
the bike was as completely personalized as the chassis I've already got.

This is an idea I'm just playing with at this point, so all feedback, both pro and con , will be welcome.
