77 kz650 motor swap (Direct Bolt)

I am wondering if anyone knows which motors 750 and up are direct bolt on's for my 1977 kz650 b1.

I am interested is as few modifications as possible.

I tried doing a search but didn't come up with anything specific and geared to my layz direct bolt on prefference.

thanks a ton.

KZ750 motor is easy, 83-85 GPz750 is a little harder, anything larger is a lot harder.

Do a search for "650 750" and you'll find posts where I went into detail.

83 GPz750 powered 79 KZ650SR in the garage.

I have an 81 750 motor in a 1978 650 frame. Just as easy as bolting up the 650 motor.

... because the KZ750-4 engine is basically a bored out 650.

... it just seemed worth mentioning. JMK.

OH REALLY!!!:blink: I stated this because the question he wanted to know was "which motors 750 and up are direct bolt on's for my 1977 kz650 b1." It is pretty fair to say that I answered what he was asking for, its not like I stated a random fact he already knew or he wouldnt have asked in the first place.

:whistle:

Come on guys, everyone is just trying to add a little info just to be helpful, I'm sure there was nothing personal meant.

On the original subject

Take a stroll through the Gallery, and take a look at some of the older threads (search), there are guys here doing some interesting swaps. I just discovered that one guy is putting a 99 Suzuki Katana motor in a 550, I have to look around and see if he's posted more on the subject as that sounds "really" interesting (like I don't have enough projects going on now).

no problem, nothing personal, sorry for jacking your thread
