FZR400 YZF750 conversion

[bat333]

I heard someone put a YZF750 motor into a FZR400 chassis. Can it be done ? I happen to have a 400 chassis and a wrecked YZF750. Any thoughts. Anybody done this ?

Its been just over a week............done yet??? I'd love to have a 750 engine to see what it would take to get it mounted into a 400. Although probably not worth the headache.....it would be more about the fun of getting it done.

I saw it done to a 2TK here in the UK. I think the YZF engine is a bit too long, wide, and tall. You'd need new mounts, then the radiator would be a bit big and the pipes will probably foul the front wheel under braking, the rear tyre would be a bit small so new rear end ... and then you might as well put a front end on it ....

contrast that with throwing a 600 in there which could be done in a weekend if you had all the parts and worked hard enough.
