37mm forks on my gs750

[Erki]

So I was wanting to put straight forks on my 750 instead of leading axle forks. found some 750 forks and went to put them on thinking I had 35mm forks on it. But turns out the previous owner has swapped on 37mm forks from a gs1100. Is there a model with straight axle I can look for 37mm forks that I can still use the calipers I have on now with the leading axle? Or I might try to swap the 35mm ones back on but I think I might need to get a larger bearing for the bottom of the stem if the PO had anything machined to do the swap.

How do you know they're from an 1100? 83 on 750/700 had 37mm forks as well. Got a pic of em?

I'll take a pic tomorrow in the daylight. As well as a pic of the 35mm forks I have. And see if both sets can be identified for me. This is the best I have on file of the forks.



Thanks.

Yeah those are later (third gen) 750 forks. Good forks. As good as they got on GSes anyway.
But you're gonna want to be careful using a different geometry with your current bikes set up. Those struts with longer/higher forks are gonna make the bike feel incredibly screwy....

The bike is getting a different stance which is why im trying to figure things out. This winter I am going to do a mono shock and lift the back end up. More sporty and fun. I have a swingarm that I got thanks to jetta90 for an 83 750E. If these forks will work for something like that then I will just rebuild them new seals and progressive springs. So these forks on the bike are from like an 83/84 750? just good to know for ordering parts for them.

Also geometry wise...what is ideal for handling. I dont want to put the back up too high im sure there is a limit. The bike was already chopped up when I got it, but I do have an 1100 frame uncut I could use maybe for geometry measurements with the factory swingarm?

Thanks for the info

The reason I was thinking of changing from leading axle forks to straight is for a touch shorter wheel base. Is that a good idea or will it make much difference?

edit, Ive been doing a lot of reading on rake and trail. I think I may just stick with the forks that are on it and see how it does with the back end up with suspension again.

Ok the pictures are in for fork Identification.

37mm forks Currently on the bike which is an 81 gs750.




And the other set I purchased assuming my current ones were 35mm which these are.






A sketch of my intentions for the bike this winter...Which forks would be better?
