soz should of said iam a fabricator / welder so it shoudnt be no prob to get it in.
like i said, you any good with a welder?
Thats alright then as a good spaceframe/cage will be needed to be made if your putting the engine at the back as half the floor will be needed to be chopped out
With access to (and the ability to use) MIG and TIG, tube bender, tubing notcher, casting equipment, pattern making, lathe and mill, gear cutting equipment and about 2 years free time, it'd be a peice of ****!
Otherwise, I'm inclined to think that a CBR engine belongs in a bike!
