Sprocket Source?

[Elimax]

Hi all:

I've got an '84 GS1150ES (I'm in the USA) and the chain and sprockets are size 630.  Do any of you know of a source for size 530 chain and sprockets for the GS1150ES?  I've looked on websites like Dennis Kirk, but all they sell for my Suzuki are for size 630.

Thanks for any help.

ive seen conversion kits here in the UK for the oil cooled GSX's.  have a look on the bay on E

Take a look on jtsprockets.com

They show drawings with dimensions for their sprockets.  Looks like plenty of 80's Suzuki's had same dimension rear sprocket with 530 chain.  Many other models show same size splined output shaft for the front sprocket,  but different location for the retainer plate screw.  Example: comparing GS1150 to GS550, the sprocket dimensions are the same except the location of that small hole in the front sprocket (and of course the GS550 uses a 530 chain).  Maybe try finding a cheap used set of GS550 sprockets and retainer plate, to do a mock-up before ordering any "performance" parts.  On one engine I have, sitting nearby, I don't even see a retaining plate; just a flat washer between the sprocket and the big nut, with one edge of the washer folded up against a flat of the nut.  A rusty GS550 front sprocket I found on the floor doesn't have the hole in it either; must have used the washer method too.

Can you remove your front sprocket cover and take a photo for us?  Meanwhile, go take a look at those drawings at JT Sprockets.

I've just reached my threshold of how may times I can type "sprockets" in one day.

I've used Z1E many times with great success

And when I have, or need, something more specialized, I look to Sprocket Specialists for help.

Sprocket specialists is a small, maybe one man operation and can be slow or difficult to connect with, but their stuff is top notch.

Elimax, did you find a solution?  We need closure.

...and don't be a one-post wonder.

Sorry about the delay everyone...I've decided to temporarily wait to replace the chain and sprockets until I decide if I like the current sprocket ratios and THEN purchase replacements.

Thanks.

I just got my crusty basket case GS1150E running, and did a 530 conversion. I'm mostly commuting and highway riding, I'm not drag racing. I went way up to a 17/42 ratio. Runs 100 kph at just a hair over 3k RPM. So much torque, and 1st gear is so short that it doesn't even feel close to over-geared. I actually bought an 18t front as well to try. I got the parts info from Z1 but ordered from Fortnine as I'm in Canada so shipping from the US kills me and I avoid it when possible. 

Z1's website gives part numbers and shows OEM fitment and also shows what else a part will fit. For example my front 17t sprocket is OEM fitment for a Hayabusa which I thought was cool.

Looking at jt sprockets site i found front ones for Hayabusa and Bandit1250 fit, the rear ones from the oil boilers; havent installed yet, so not 100% sure.
