A 530 conversion question

Thanks for all of the information. I should have posted prior to making my purchase of the front and rear sprockets in the 15 and 42 stock sizes. I hadn't even thought of the issue of swingarm clearance. I'll give it a close look on reassembly to see how close the chain comes to the swingarm. If too close for me, I guess I'll be removing the rear wheel and engine sprocket again for larger sprockets. Live and learn. Keith
 
thanks for all the info guys! Looks like I'll be doing a 16 48T. It's more important to me to get a boost in the lower range. I think cafekid mentioned going a 17 so that you can go up or down on the back without changing your chain. I might do that actually.
 
all things being equal, a larger front sprocket is easier on the chain and on the sprocket. More teeth engaged and less of an angle movement at each link.

Most bikes were sold with gearing for impressive acceleration numbers in tests, and can be geared taller for more relaxed highway use without any real loss in useful function.
 
I just ordered the 17 tooth countershaft and 48 rear sprocket in the 530 size. My dealer has been really good about dealing with my mistakes. Off with the 15 and 42 then. Thanks again.
 
I went with an 18 on the front for the chain wear issue already mentioned when I did the 530 conversion on both my 750s

That ebay seller that has been posted a few times, jawzys, is where I purchased two 530 conversions. They were good about fixing their mistake when they sent too short a chain(I guess they'd never had people order the 18/50 size sprockets?), but the extra down time sucked.

Edit: Hmm, I can't remember for sure, but I think the listing for 18/50 combo for a 750 also said 106 link chain when I bought from them. It was 2 links too short. If that's the case they never updated the listing and if you're gonna buy from them email first to check the length.

You can. Also I tried fitting a 16 530 front on a gs750 with an 1100E swinger and it was too small and the chain wouldn't clear the pivot cleanly. I would assume you'd probably have the same issue with the 1100E but can not say for sure as I've always used either a 17 or 18 tooth on the front. Also, with the 18t that Z1 used to sell (I say used to because I do believe Jeff switched vendors for these) there was an issue with the sprocket being an odd width. The spacer they included was too wide and didn't leave enough thread to tighten with the fold over washer, and with a 4mm spacer there was obvious slop in the sprocket on the spline. The 17t fit perfectly, nice and tight etc. I'd guess a 5mm spacer would have probably done the trick but I didn't have anything of that size. I just went ahead and put the 17t on instead.
Like I said however I think I remember Jeff saying he switched vendors on those. At the time the 18t was a different brand than the other sprockets z1 carried.
 
What is the importance of the 6mm spacer? The z1 website says it goes on the outside of the sprocket, not between the sprocket and the case. I know it makes up for the rubber dampeners on the stock sprockets.

Can't tighten the countershaft nut down without it.

Got all my drive stuff locally.Only shipping I paid for was the 17t front with spacer built in I got from Katman.Went to the only bike shop in Sooke and got good stuff for not much more than getting it from the US would have been.Pretty cool in my books.

No it's not gold like on the cover,I can live with that;)
 
I did a 18t-Front/49t-Rear, straight conversion to 530 gearing.
It fit perfectly on my 78 750.

I bought a 530-116 Link sportbike chain from ebay.($64)
It's listed for the gsxr/cbr/zx/z1 1000cc+ modern sport bikes.
Fit like a glove, didn't have to remove any links.

Not trying to hijack, just wondered how it turned out?

Boy this stuff is confusing. What did you end up putting on your 78 gs1000?

I am looking up the parts for mine and just called Z1. They suggested that a 17/49 with 114 or 116 link chain would get me to just a smidge more torquey than stock.

I hope all that is correct??

.... also, they did not have the gold or any colored chains to go with the upgrade.
 
Me?Check post 30.A 530EK X ring chain,plain.17T front with spacer built in from Katman and a 45T JT rear as that was as close as I could get to 47 in Canada when I ordered it.
