1000 engine in a 750 frame?

ok so i'm still looking for an engine and i was just browsing when i saw a nice kz1000 engine. just what kinda mods would i have to do to my 750 frame? i wanna know if it's worth the hassle, because i can't find any 750 engines cheap enough and this has a pretty good price on it

You'll have to gusset the frame to handle the extra power and will have to make you own motor mounts, but with skill it can be done. Below is a 1000 in a 650 frame!

that is just beautiful! i was thinkin i'd have to cut up the frame and re-weld some stuff, but that doesn't look too bad, now i just need to find someone with some tools to use since i lost most of my stuff in the divorce

Make new motor mounts to set the motor as low in the frame as possible, that way you won't have to modify the fuel tank for clearance.

Is that an oil cooler just beneath the triple tree?

Looks like one.

A GPz750 Oil pan and cooler will bolt right onto a 650.

and make sure you use bolts on the three lowest clutch cover holes, otherwise you'll have to unbolt/lift the engine to get at the allen heads.

You know, you will have to do a search, I hope the pics are still hosted there, but in the archives, there was a guy that put a GPZ 1100 motor in a 750 frame, and had it so that he could still remove the valve covers.

Also had USD forks and kick ass rims. It was about 90% finished in the last pic he posted, and I didn't hear about him again, even though I think I posted a couple of posts on the thread.

that is a 1000\900 frame in that pic just look at the rear foot peg mounts but a 1000 motor can be put into a 650 frame just needs some modificationsB)

That was messenger1, one of the sweetest builds ever - pics are still there though I haven´t seen him around in a good while:

Pretty sure its a 650 frame. There are no stud holes by the swingarm pivot bolt for the standard foot peg mounts like the 900/1000 and the rear foot peg mounts are closer and higher to the frame than a Z1 or 900LTD.

It´s a 650 frame alright, the bike used to belong to KZR member Zman, if I remember correctly he put it up for sale a while ago. Here are a couple of links where he mentions modifying the rear peg mounts ao - unfortunately his pics are no longer there.
