Am new to bike building and i,ve hit a problem?

i have a cb 750kz i also have usd forks of a hyosung gt 250 but the yokes dont fit the headstock in the 750 how do i rectify this i no the bearings need changed but what elseAm new to bike building and i,ve hit a problem?
I don't know the dimensions of the Hyosung front end, but I'm willing to bet they are not a direct swap. The easiest way to swap would be cut the neck off the Hyosung and weld it on the CB frame.



Of course, now the VIN numbers don't match the engine numbers, which presents more problems. Such is the case in bike building, when making decisions, realize that it's going to create another problem, the choice should be the less difficult subsequent problem rather than the more difficult one.



Modifying a Hyosung front end to match a CB neck would be difficult and could end up being dangerous to ride. Of course, if you don't have the frame to the Hyosung, then you should not try to mount the front end on the CB frame.



The steering assembly is the most important part of a bike in terms of safety. A broken steering stem will result in a long series of cartwheels as the front forks and wheel fall away.



Depending on where you live, you'll either have to register it as a Hyosung (if you use the neck), or a CB if you custom build a steering stem.



Another benefit of cutting the neck cylinder off the Hyosung is that you can weld it to the CB frame at any angle or rake that you want. Email me if you want more details.



EDIT - Jancie, or Janice, or whatever you're calling yourself, the Hyosung 250R shares the same framework as it's 650cc big brother. Remember, we're talking about a custom bike, sort of like putting a Buell front end on a Sportster. The performance of the Hyosung front end is going to be sufficient for the CB drive train assuming that it is assembled correctly. Not everybody likes riding something off the showroom floor. I would think that you, of all people, would appreciate someone who is trying to stand out a little bit. Or at the very least, have a bike that doesn't get lost in the parking lot full of generic wannabees. Putting a sportier, race-looking front end on a CB, I think Soichiro would be proud. A dream? The first American Honda was called the Dream. In fact, it's the symbol on the front of the Honda museum. I can't believe I'm saying this to you, but try to be a little more open-minded.Am new to bike building and i,ve hit a problem?
The issue that I have with it, is that the forks from a 250 are suppose to support and dampen the ride on the much heavier 750? In what dream? The overall fork size needs to be larger and the fork springs beefed up to handle the stresses that a 750 inline 4's engine will put on this assembly. Never mind the hack job required to weld the head pipe onto the Hondas frame.
