82 GS1100E Mr Turbo Rebuild

[oldGSfan]

Took a longish ride today and it was great, now doing 'post mortem' I have a little bit of dye in the oil to do some leak detection. I looked all along the base, head and valve cover gaskets and they seem fine. I do have a pretty bad leak at the turbo's oil return fitting at the oil filler (see pic below), and it's spewing all over. There is an O-ring that looks fine but the tightening ring/threaded part doesn't squish it down visibly before it tightens up. It's hard enough to turn and I don't want to strip anything, but I carefully tightened it and it's as good as it'll get. But possibly there is a secondary seal inside.

It's an easy thing to sort out I'm sure, and then once sealed I can pinpoint anything else. The cam chain tensioner and oil supply running off the pressure switch have some oil but I bet it's from the return line.

It also leaks just a little bit from a couple of the rubber half moon 'cylinder head plugs'. I recall there are two O-ring gaskets that are inside the head (I see them on Partzilla) that, if leaking, can make a mess of the top end. There are also 6 gaskets that look like they are copper, not sure if they can be an issue.

Other than that, I definitely need to upgrade the forks and address some little things - like a proper air cleaner. I just ran it today with the velocity stack and mesh screen that keeps bees out.

Bike really wakes up at 7K!

Seriously, Rob, you need new brothers.

I'll have to mention it to Mom and Dad next time I'm at the graveyard.

Unfortunately some don't recognize the mental health benefits of riding.

Exactly! The nicer the bike, and the more of them you own, the happier you are. It's science.

... my two brothers today told me they would make sure I never ride a motorcycle or drive a car again. They don't even want me to attempt to get back on my ten speed English racer.

Seriously, Rob, you need new brothers.

EPM - by Arturo Magni of Italy - MV Agusta fame. Pretty rare. Front is magnesium 18x2.5 and very light. Rear is aluminum, 18x3.5. The original owner really did like his top shelf gear.

Bike looks awesome and sounds great. What wheels are those?

I've had the Napoleons on mine for ages. The fairing mounted mirrors on the 1150 are mostly useless.
No need to cut the throttle tube on mine as the 1150 came with factory bar end weights.

[oldGSfan]

I have a 2nd Napoleon bar-end for the throttle side, plus the originals. Napoleons do the job just fine but I'd have to cut through the grip and throttle's plastic sleeve, and I just got a genuine Suzuki one so I'm hesitant to cut it. I have to decide, been waffling. As it is now, having just one bar end mirror, it's not good enough, so sorting this out is the next fix in the line.

These old bike look so much cleaner without mirrors. Not practical / safe, but it definitely makes photos nicer.

That sounds absolutely awesome, love it!

More smiles per mile...looks like a fun bike!

Dammit. I am just green with envy. I have been looking for a GS11 turbo for ages. Congratz oldGSfan. Very well done.

Nice video....the grin says it all.
You hooligan! I'm callin' the Fuzz!

[Rob S.]

Sounded great! Thanks.

[oldGSfan]

Well, my son took a couple short videos of me riding to the end of the cul-de-sac and back. In shorts and flip flops, no helmet. Don't report me to the fuzz! I am setting a bad example, will do better soon. I want to use his 360 cam that has a chest mount this weekend perhaps. I also may take it to Cars & Coffee. It's got a head gasket leak and puffs a bit of smoke but is fine to ride and I'd rather just enjoy it until I finish my CB750, then will get it sorted.

Sorry to hear that you are not going to ride Rob.
