GS1100E Money Pit Thread

Ok, back to the rear end. I have it pretty close, maybe a mm or two off still, but getting there. This is the stock top hat on the left side.




It looks like the left top hat needs to go down about 1 maybe 2 mm, but that introduces this issue.




Where it looks like the bolt that holds the sprocket to the carrier will nick the swingarm. This is the stock 630 sprocket, which will be replaced with a 530, maybe a 520. Just grind down the carrier bolt to get that mm or two?

Since U are using a stock GS swing arm (it is symmetrical and centered in the bike frame) , it would be best to make sure that the distance from the inside of the fork to the tire or rim is the same distance on both sides. That reference to the center of the tire is not gonna work very well.

Good thinking. I will measure that up. I thought the stock swingarm (not being offset at all) should simplify things. I'd add, this was not intended as a final method to have it perfectly centered, just a quick and dirty way to get it pretty close to see what interference issues where there, and indeed I found one. The sprocket carrier bolts.

I saw in one of the 1100 530 conversion threads that 17/48 was pretty close to the stock gearing. So, if I wanted to do a 530 conversion with the the RF900 rear wheel, I'd get the 48 tooth rear sprocket for an RF900, and a 17 tooth front sprocket for a GS1100E (with the appropriate offset) correct?

Edit: And I'd use the 1100 length 96 link chain. So, 48 tooth RF900 Rear Sprocket, 17 tooth 1100 front sprocket of the appropriate offset, and the 1100 length chain (because using stock swingarm, and stock diamteter wheel).

96 links doesn't sound right for a 530 chain. I use 116 on my bandit arm, others use 114 on stock arms. Takes more 530 links to = 630 links. Best bet is order 120 links and cut to proper length after test fit. I use 17/47 combo. I think that results in a little more bottom end.

My 1100 use to make a barely discernible top end whine when I had reached my typical cruising speed and the revs were around 3000 rpms in 5th gear. With the tad lower gearing it puts my revs closer to 3300 and eliminates that old noise. Puts the engine in a better place to accelerate from. I have Stage I Yosh Cams and 1134 Yosh pistons so that may have something to do with it but I seem to remember always hearing that whine even when it was close to new and before the engine work. Your results may differ.

Ok, that makes sense. The 96 link "stock" for the 1100 is a 630 chain, and the smaller link size of the 530 would make it more links. I haven't owned a chain bike in 15 years. Gotten used to the shaft drive, so all this sprocket and chain stuff is having to sink in.

Little searching on OSS. One option is to reverse the sprocket. Probably gonna go ahead and order the rear sprocket so I can get the rear centered. can't do it with the stock sprocket. Hit's the swingarm before wheel is centered.

Are you using the GS hub in a RF900 or Bandit wheel . If no you should try it. I have my sprocket reversed. Not very pretty but modders can't always have their way.

Have the RF900 hub on there/sprocket carrier on there. Of course! I should see if the GS one will work, and made not be as wide. Thanks sir!

I'm really working a lot out as I go along, first time to do there kind of mods. I have read a lot of threads, but really have to get into your specific situation with the components you are using and work it out. Maybe I'll start referring to it as an "EFE" in honor of you Brits.

Right mate, here's some additional reading and pics on the subject http://www.thegsresources.com/_forum...d.php?t=152597.

I believe the Bandit and RF900 share the same part number for the rear wheel. Your moving fast but you need to start planning on how your going to handle your rear master cylinder.

PS ISLEOMAN is just a screen name I was born in Union City,TN and live in New England. Seeing the Isle o Man race is on the bucket list. Maybe next year.

Here's another build with some details on pages 2 & 3 about brake mod.

[doctorgonzo]

Haha!
Funny about Union City.

On the rear master. I have the RF900 rearsets with the integrated one, but not sure how well they will bolt up, but that's the route I'll go, maybe a GSXR set.

Nice read. Thanks for the link.

It is a good read. The only reason for me to relocate my rear master is to use rear sets. I am using the stock swingarm, so I don't have the clearance issues he does.

[Bad Kaw]

Ah, so you are using stock pegs then. Makes sense, then.
'Pegs' was the one area that I thought that guy might have addressed (in the link), but didn't. Seemes like a relatively simple modification that would have gone very nicely with his particular bike...would have complemented his other mods.
But if you're keeping your suspension stock and most other stuff I can see staying with whatchya got...stock is pretty comfy.
Oh, I have seen Katana guys put GS1150E/ES footpeg assemblys on their bikes with little or no hastle and they look good. Just a thought.
