Hello I am new to this sight and have been pleased with all the information. My question is, do any of you know if a chain drive trans is a straight swap into a gs650g shaft drive frame. I am wanting to hardtail it and want to change to chain so I can change the gearing on it. Thanks for all of your help.
 
You can not simply change the transmission, you have to change the entire crankcase.

If you have your heart set on a chain-driven GS650, they do exist, as the GS650E. Your shaft-driven bike is either a GS650G or a GS650GL.

There are some that have sucessfully hard-tailed a shaft-driven bike, but you have to be careful how you attach the rear frame to the final drive unit. The existing shock mounting point is not engineered for the high shock loads of no suspension. The shock mount on the right side should be no problem.

Why are you wanting to change the ratio? It is geared nearly-perfect for that engine as-is.

Ok thanks for the info. I was wanting to change the gearing for a little lower rpm around 70 mph and highway speed. Seems like it revs high like around 6000 I'm just concerned that this high of rpm will damage the motor

It's a small, short-stroke engine that LOVES to spin. :D

Too bad you plan on hard-tailing it, you will miss out on all the FUN that engine has to offer. :-\\\

I'm not gonna hardtail it if I can get some shorter springs. It is tall for me. I love the bike. It's a blast to ride and I love the old four cylinders. So running that high of rpm is ok as long as valves and all are good. If I keep the springs I would like to get some hard saddle bags and make it look sort of like a dresser

Click the link in my sig for my son's 650L for a preview. :D

Shorter shocks are available from Progressive Suspension.

That's a beautiful bike. Does it still run decent at highway speeds with the extra weight for saddle bags and all
 
Didn't weigh them when we put them on, but I don't think that the bags and the brackets weigh more than 30 pounds or so.

Yes, even when he slows down to "highway speeds", it still handles well. :eek:

These particular bags are not water-tight, so he has to pack carefully. Other than that, we are extremely happy with them.

There are still a few more details that need to be added, then we will post an updated picture.

Seems to me the better route may be to find a 650L and swap. The seat is a bit lower and may be a better fit for you in terms of style too. I'm only guessing there though.
