GS1000 streetfighter idea w/ picture

[80GS1000]

Do you know if the pc310 has enough oomph for a big GS? I got a 535 but it would be nice to go smaller...

Should be, we'll see. The stock battery for the GS is rated at 12 amp hours, the PC310 is rated at 8. It doesn't have the reserve of a bigger battery, but it is much lighter and can be mounted in any direction except inverted which is a huge plus in this application. The cranking amp output on the PC310 is pretty incredible for its size, which is the most crucial aspect as starting the engine is the battery's most important job. The GS1000 racebikes didn't even have a battery to save weight - bump start only.

Yeah, my 535 is an odyssey as well, so it'll mount on its side too. bigger than the 310, but I should still (hopefully) be able to hide it up under the seat somewhere.

As a contingency plan, just ordered a 5/8" offset 520 pitch 17 tooth front sprocket in case spacing out the GSXR 1000 520 front sprocket won't work when it arrives. Putting spacers behind the stock 630 front sprocket to offset it 13.5 mm had me concerned about the amount of leftover threading for the front sprocket nut. Only about 3 threads were left and the 520 front sprocket will only gain us about 2 mm of extra threading. The sprocket was hanging pretty far off the spline so that was another concern. Wouldn't want it to come loose under load.

Price for the new custom sprocket was reasonable at $50, should take about 2 to 3 weeks to arrive. I'll post the number for the shop that's doing it if anyone's interested.

Turns out the Odyssey battery fits the stock battery box like a glove, except it's about 1.5" shorter than the stock battery. Much lighter too at only 5.9 pounds. Now just gotta figure out where to place it and the electrical board.

Curious where you got the front sprocket, as i've only seen 530 sprockets. I'd rather go with the 520, just for the width/weight advantages.

Round #1 of parts for mounting the GSXR swingarm to the GS frame are back from the machine shop. Very nice CNC machining of 440 stainless to make these parts from specs I provided. 10 bonus points if you can guess what they are for. (hint: the larger parts are identical)

ummm... to fit a very nice swingarm?

The more i watch you sort that out, and especially fit that swingarm, the more i'd like to do the same to my bike.

Bushings so that you can use your stock swing arm pivot bolt??? Smaller piece...have no idea....

[Chris Bohane]

A very , very nice machine.
I too would leave the bike as it is....full of character.
Modifying it , I think, would turn it into a collection of assorted "spare" parts.
BUT...what do I know? I turned a GS850 into a trike.
Pics on request.
Regards to all.

Right on the money about the two larger bushings are so that we can use the stock swingarm pivot bolt. They are replacements for part 1 below. The smaller one is a replacement for the spacer inside the lower shock linkage pivot shown below next to the number 2. That stock spacer has a inner diameter of 12 mm; I needed a copy of it made with an ID of 10 mm to help mount the lower shock pivot.

I'd love to see a pic of a GS850 trike. :-D

Hehe, and you even have me to guinea pig these mods for you before you even begin.

You might wanna be careful with the spacing. I had to offset the center hole in the spacer so that the swingarm would clear the rear of the motor. Mine is offset and it is still pretty tight. Hope it works out for ya tho.

Which swingarm were you trying to fit to which bike? I eyeballed swingarm to engine clearance at about 5-10 mm, so that part should be OK.

I remember your photo here:

04 gsxr750 arm on a 79 gs1000. Like i said, i hope it works but i had to offset the hole on mine. Perhaps your arm has different dimensions @ the pivot point
