Hi, Im new on here so go easy. I just bought a YZF400 exup 3en1 and i would like to know o few things.
Here we go, What HP has the engine got & what top speed, what parts are interchangeable, can i get a workshop manual for it, if i opt for a 600 engine what one would go straight in or with little modification. Any info would be great. Thanks Dave.

youwont find a haynes manual for one but there are some sticky posts in this section that you can download from!
hp is prob high fifties but it depends on the engine!
there are lots of parts that are interchangeable but there are also a lot that arent! best to see what you need then ask!
Have a look at the other posts for info on the 600 engine, they dont just drop in though!

cheers taggy
