KZ750 front end swap

I recently bought a KZ750 from 1981. I'm on my way to do a front end swap on it. I'm looking for the easiest fit on as possible. I have the opportunity to buy a 06 zx10r complete front end ( forks, triple tree, wheel, brakes, masters etc.). I was wondering if this is a good idea? Should I be worried about the forks being to wide and knocking on the frame while turning? What's y'all opinions and idea?
Thank you, Ethan

Like I said with mine,I was lucky and got away with it. Don't know what I would have done otherwise. I never even considered that it might be a problem. I know that some old cafe racers used to hammer dimples into the front of the tank to accommodate clip ons. It might work but a bit drastic though.
If you have access to the ZX10, you could measure the top yoke and make a copy out of wood. Offer it up to your bike and see how much of a turn radius you get. Lifting the tank might work but it would probably ruin the lines of the bike and look crap. Don't know. Maybe others here have a suggestion.
More things to think about are matching the wheels. If you use the ZX front wheel what are you going to do on the back? Will the ZX rear wheel fit? What swingarm to use? How to deal with the chain offset?
Also, ground clearance. Expect the new forks to severely lower the front end. Whats that going to do to your exhaust downpipes. I used the ZX9r forks which were meant to be the longest of the Jap USD at the time. I still had clearance problems and had to fit extensions to the fork tops to bring everything up a bit. (So, if you get a chance to measure the top yoke,you should also measure the fork length with the wheel to see what your,e in for.)
There are many more of these issues to think about, the ones above are just what comes to mind right now. Best thing to do is read as many build threads as you can. A lot of people here have gone through the same thing and there's a lot of info on what can happen and how to get over it.
Good luck.

If you find a front end that is close in length, and has the offset and rake & trail you are looking for, you may be able to get away with putting the KZ steering stem in the new lower clamp, thus retaining the stock size steering bearings.
There are a lot of variables involved.
