1983 GS750ES Carb Help

I finally picked up a winter project. Needs the normal stuff from sitting to long. The big problem is it needs the carb Diaphragms replaced or repaired. One or more are ripped from age. The bikes running 1986 GSXR1100 34mm carbs. Prices are $130 each at the low end and up. Anyone have a good used set of 34 carbs.

Second question is tires. Anybody using Avon AM26 and do you like them ? 120/80/16 and 130/80/18 limit choices.

Thanks

Those Avons are really popular on older bikes. That's what I put on the FJ and I like them a lot.

I'd look on eBay for a set of used diaphragms. Check out ebay.com - a lot of scrap yards don't ship outside the US. I have my FJ parts shipped to Crossborderpickups in Niagara Falls, NY then I pick them up in Mississauga.

I ran AM26s and was very happy with them... it's been a while since then, but bias-ply tire development hasn't gone anywhere in the meantime
 
Going to try the ContiClassicAttack radials next, reviews are extraordinarily good. I don't think they're available in the OP's sizes though.
 
just throw another $600 at it and slap on a set of FCR's, be done with wimpy diaphragms and such lady parts.:director:

Ya it has all the period stuff. Astralite mages and rotors, Lockheed calipers. Fox shock, Progressive springs up front. Last owner had it 25 + years. Came with a load of extra bits including full bodywork. Best of all the bike and I are eligible for classic insurance.

I'm thinking of trying this stuff "Loctite ULTRA Gel Control Super Glue" It says it leaves it flexible. Maybe cut up one of my old CB carb diaphragm and glue it on. I have the carbs off and apart. Show some pics tomorrow.

Good to know. He couldn't remember where he got them from.

Pics of one diaphragm. You can see the glue he used is peeling off after a season or two. Thinking of trying to fit my 89 Kat 750 BTS36SS carbs.

Did that GSX-R motor drop right in or did you have to make custom brackets or weld on additional tabs?

The motor, more or less, bolts in. If I remember you have to enlarge a hole or two on the brackets, and fab a rad mount.

Now my question; Anyone know if that early Gixxer transmission will fit in a GS?
 
if thats a gsxr motor, buddy in ottawa has a set fcr's that would fit, probably mint cv carbs too, used fcr are about 5-600.

This was a fail ! My version of flexible must be different. It does state no hot liquids so it might come off.
