82 GS1100E Mr Turbo Rebuild

[oldGSfan]

I bought my son 14 y/o, now 15 (only kid so he's spoiled) the YT carbon frame enduro when it was 20% off. He had a Fuji that I got from Performance Bike when they closed, and he rode the wheels off it. In one year he went from a 5'3" 150 lb slightly pudgy kid to a complete fitness stud, putting in well over 100 miles a week. He grew to 5'10" in about 14 months, and still weighs 150, but is solid muscle. He logs his rides on Strava and has a blast. Altitude gains of 2 to 6K' on a typical 20 to 40 mile ride Best investment ever - he hits all the marks, nature, fitness, friends, and mechanical interest. I ride with him but he's so far beyond me it's pathetic. I can manage about 15 miles and I'm gassed, but happy to be with him and getting some exercise.

Been MANY years since i was on the trails and the YT bikes would have been out of ability and price range but their site was cool to look through.
Carry on.

That thing hanging off the headers below the engine, can I assume that's some sort of waste gate, in case too much pressure builds up? Question: if that opens, don't the decibels rise?

Man this thing looks great!

Yeah losing that front derailleur is great, it's a SRAM Eagle, 12 speeds. Front is 32, son has even smaller on his YT Capra, but for me the lowest gear (biggest sprocket in back) is so low that it's more work for me balancing the bike at crawl speed than it is to pedal.

One ring in front is possible because the rear derailures these days can shift a crazy wide rear spread in back.

Just being nosy but what's the story on the sprockets on the mountain bike in the background?
The front look so small. A 26? Is that for climbing uphill?

Looks fantastic, bet you can't wait to get those wheels back!

[oldGSfan]

I got the wiring and oil cooler done, headlight always fun, ship in a bottle on the GS1100E. I must have latent memory because it all worked out fine on first try. Still waiting on the wheels, hence no brakes.

[oldGSfan]

Yeah that makes sense, they are Progressive shocks, I think a tad longer than stock. No worries for now I'm happy to have it on the side stand only.

I've seen that caused by differing front or rear springs. Just saying, before you go cutting and welding the stand...

[Rob S.]

The stand seems short, it doesn't raise the bike in the rear at all. Need to investigate, might be modified...

Got the powder coated parts so I installed and couldn't resist chucking the bodywork on there.

Mounted the center stand but the spring I have is wrong, so I took it off. The stand seems short, it doesn't raise the bike in the rear at all. Need to investigate, might be modified for some reason like so many other little things I've discovered.

The front of the seat needs to sit against the tank, right now there's a 1.25" gap that looks bad. I am thinking of a couple straps made from a spare tie-down may help, by attaching with tension under the front area.

[oldGSfan]

Thanks, getting last needed parts tonight so I can get off the chain hoist - stands plus various bits that were a bit rusted from the salts. Got a few things to mount and figure out but I'm on the home stretch.

That is looking so awesome.

[Spyder]

That is looking so awesome.

I got sick of trying to find out what gasket would fit the various Mr. Turbo flanges and just made them myself with Mr. Gasket 77 stuff. Put in the new exhaust gaskets at the head, and mounted up the manifold with some leftover new Gates 1.5" hose from the parts stash. It's a bit of a tricky fit, I still have to jimmy the thing into the best position to ensure a good seal on the single large intake hose. Tomorrow.

It is very gratifying to see it with the pipe and turbo stuff on it. What a beautiful engine.
