XR250/400 Conversion

Does anyone know if the dimensions (as in physical size) of an XR400 engine are similar to that of an XR250? I'm thinking about putting a 400 engine in my XR250 supermoto commuter and I'm down with making new engine mounts, just not large scale re-working. Ie, if it's too big a job it may be easier just to get an unregistered 400 and restamp it with the engine and frame no's of my 250.

Cheers.

when you have binned the bike and someone gets critically injured and the bike gets inspected for cause of accident etc

Anyone who looks at the restamped frame number would know! It'll never look right.

To be honest, I don't think you'll get much benefit by swapping motors. Neither of them are very swift. A mate of mine has the 250 with a 280 kit in it and it was pretty much on a par with the 400's. Get a WR or something if you want decent power. :pb2:
