You would definitely reduce available fork travel, without adding any extra stiffness. I think you could bottom out your suspension quite often.

The front suspension on my 500 is real soft. I haven't gotten around to upgrading it, and I can assure you that it sucks when your front bottoms out.
 
I like the idea of just raising the fork up a bit. You could always use thicker oil or add more pressure to the air shocks to counteract it, and might even end up with better handling in the process.
 
I will see how much preload travel I currently have on the front suspension and then see how much difference there is between preload and bottoming out. I just havent had any issues with it bottoming out - if anything it is too soft and has way to much travel.

If there is enough travel remaining between the two, I do not see how there could be a problem cutting the distance in half and removing that much of the spring. Cutting the spring should not effect the original spring weight - should it?

What you mean apart from de-tempering the spring??
Call progressive and buy a new shorter spring instead!!! best of both worlds better suspension control and lower ride height.

Spring constants are spring constants regardless of length. But the amount of spring compression is directly related to how long your spring is.

If you want to cut your springs, go for it. I don't think that is the greatest solution to your problem, but I suspect the worst that could happen is you ruin your ride for a while till you track down new/correct springs.
 
springrate is the tortional module for steel (11,250,000) times the wire diameter in inches cubed all divided by 8 times the number of coils times the mean coil diameter in inches.

so with that said, if you decrease the number of coils total it will increase the springrate of the entire spring.

not enough to compensate for the travel lost.
 
I agree, but the spring rate greatly increases when the coils are touching :D

Very nice work!!!

I like the final look that you got!

I can't wait to cafe out another zuki....right now I just started building a Yamaha XS650.... too bad this is a only "GS" forum.....lol...cause just from looking at the xs and the way it sits...it should turn out to be an awsome Cafe Racer!! and I'm sure I'd get flamed and maybe even booted for even talking about a Yamaha....LOL :-D

Good luck and keep up the good work!!

I was doing some tinkering and decided to take a short video walkaround of the bike. And it is an excuse to play with youtube.

I should be picking up a fairing from a friend this week to test it out and see if I like it. If not then those gauges gotta go.
 
Those sure are some crazy bars. How's that feel after half an hour?
 
My love of things two wheeled also includes bicycles. I have been riding road bikes for quite a few years. The riding position on my pedal bikes is very similar to the position on the motorbikes. The result is that my back/wrists/arms are in pretty good shape. Not trying to brag, just saying that my body is pretty conditioned to riding for extended periods of time in that position. I also find that the angle of the grips on the clubmans is the same angle that my fists naturally fall into when I extend my arms, so they are very comfortable.

The only issue with that position is the foot pegs. Moving my feet back would make the ride a little more comfortable. I am thinking about a couple of solutions. The main problem is that I really like having the kicker, and a lot of my thoughts so far get in the way of that. So know I am faced with the added task of modifying the kicker.

As for now, when I ride and I am in a good gear, I just move my feet to the passenger pegs and it feels great.
 
You could install some rearsets which would both move your feet back.


Cut some steel plate into the correct triangular shape, then drill and tap the plate for the mounting bolts. Weld the plate to the frame. Then install GSXR rearsets. See the photo below for an example. Would let you retain the kickstand as well.

If you don't want to go the fabrication route, Raask makes rearsets for the GS750: http://www.raask.se/e-fotpin.htm

Okay,...I gotta hi-jack here for a second.

What are the clamps for the headlight there? I absolutely NEED to have/make those.

Thanks,
Mike
 
I should have been more clear. Not kickstand, kickstart. Those rearsets would get in the way of the kickstart. I am thinking about trying a shorter kickstart lever, I don't think it would increase effort that much.

Where exactly is the kickstarter? Don't think I've seen a pic of a GS with one.

Alright, I am a little hungover today and not on my A game. Are you messing with me? There is a kickstand in the picture in your sig.

Me either, apparently. :lol: Kickstarter, meant to say.
