82 GS1100E Mr Turbo Rebuild

[oldGSfan]

Got the Avon on the back, the fit of the 140 is fine, plenty of room even all the way forward, so a 150 would have fit. But I'm happy with it. I'll mount the front tomorrow.

[oldGSfan]

A little update. Tires arrived, and I am hopeful the 110/90-18 will be OK. I can't see how it will foul the fender bolts, there is plenty of clearance. Unmounted and obviously not pumped up, its the same height as the 3.5 stock 19" tire, and about .4" wider but I suppose that it'll grow a bit.

I am mounting myself, never did that before but slipped the one bead on the rear with no problem. I am going to try out tire balance beads, been reading up on them. Worth a shot for $10. I don't want weights stuck to the pretty gold EPMs.

I mounted fuel pump, pressure regulator, and filter, and wired the pump to the kill switch. It came out very tidy.

The inside of the gas tank looked clean, I could see no rust, but since I can't see way down I went ahead and filled with cleaning vinegar, and it was a good move because the fuel sending unit leaked, and on further inspection the unit was not in great shape. I recalled there was a spare and it is really clean and works fine. It had no float so I had to transfer from the other, with a makeshift fastener. The rubber gasket on it is much more pliable and should be fine, we shall see.

I talked to a local tuning shop and the owner said he worked on and tuned many Mr. Turbo GS's and Z's way back when, and will set up the jetting on dyno for $500. Seems fair but I really don't know. I was encouraged by his knowledge during our brief chat.

Finish the tank, mount the tires and bleed the brakes are all that's left, all electrics are sorted. Won't be long now.

[oldGSfan]

Yeah I hear you on that. I will check the fit and if any doubts will return, it's free to do that. More isn't always better on the front especially. The stock tire is 3.50" which is 89 mm so this is a big jump, but the tape measure says it should clear. Might have gone overboard.

A 100 on the front is actually near-perfect.

Several have tried to go to a 110 and found that there are clearance issues with the fender mounting bolts. Those that found enough clearance did report that it felt like the power steering got turned off. Most went back to a 100 tire.

The front is probably wider than ideal (100) but measuring the circumference it is the best match for hugging the fender curve, and the rim width as well. It might make the steering a bit heavier.

Since the carburetor has an accelerator pump you can just pump the throttle to start it. No need to choke.

[oldGSfan]

Yeah best to have on left but cable's too short for now at least. I will move to other side, have longer cable and shroud in the pile somewhere.

Right side choke. Interesting.

[salty_monk]

Kick it in with your foot maybe...

It's warm enough here all year round that you don't need much choke for long anyhow...

[Rob S.]

[oldGSfan]

Got a choke cable, which didn't come with the Mikuni HSR42 kit, so I made an aluminum bracket at the engine mount, a quick job but I think that it'll stay. I don't want another cable to route up to the bars.

[oldGSfan]

I ordered Avon AM26 in 140/70-18 rear and 110/90-18 front. The 140 will fit for sure, and it probably won't last very long . The front is probably wider than ideal (100) but measuring the circumference it is the best match for hugging the fender curve, and the rim width as well. It might make the steering a bit heavier.

I have to make up cables for the Mikuni, the standard ones I have are too short. I got a Venhill kit that arrives today, looks to have all the bits I need and more.

[Spyder]

A 140 is the widest I could fit under my '83 750T. Anything bigger would drag on the chain, and likely the swing arm while cornering.

[bull958]

Dont quote me on it, but with a 630 chain I think your limited to a 140.

[oldGSfan]

I'd like a 150, may fit with wheel backed out pretty far. i don't want to chance it, will measure as best I can. There aren't many choices either way. Looking at the Avon AM26.

I know it depends on the wheel and tire but i have a 3.5" spoked rear wheel and a 150 BT45 fits fine.

[oldGSfan]

Yes, will do. Getting back at it after a week in Sedona. I think I'll get a carb main jet extension kit and the needle and seat that Mikuni recommends for fuel pump. Then take to a shop to get tuned. Working on the wheels and need to figure out tires, will mount rear rim and do some measuring but I think a 140/70-18 on the 3.5" wide EPM should do. I also need good quality vacuum and fuel lines, and a few little things like a rivet link for the new 630 D.I.D. O-ring that came with the bike.

Hope you are planning to video the first start! Can't wait to hear this bad boy in action!
