XS 400 Question

[Two Wheel Mafia]

Is the head on the 400 the same as the 650 just a smaller bore? Will a 650 head bolt on to the 400 block? I know the pistons and all that would have to chance too but can it be done. Like Mikes sells a 750 kit for the 650 would any of that work on the 400 or do you know of anyone that makes a big bore kit for the 400?

Inquiring minds wanna know

I've read somewhere along the line about someone doing an overbore with Yoshimura pistons. No head swap or kit though.

Short but interesting read here, maybe you could get more info: http://forums.sohc4.net/index.php?topic=9766.0

Looks like you would end up with an overbore to 468cc? That could be fun!

Anything is possible. Don't give up on the dream!

My brother mated a 650 head to his CL350 when we were kids. He also drove it off a cliff and it was hell getting it out of the ravine he ended up in...
