Thanks for realy, Maz. Luckily I have a donor carb assembly on the way. Hoping floats there are untouched...😊

Here's the link to the relevant page on Randakks site.http://www.randakksblog.com/floats-101/
As it states, this is for the GL1000 but essentially, the GL1100 only differs by having a 15.5mm float height, instead of 21mm for the GL1000. If you scroll down the page, you'll see floats in a MUCH worse state than yours!

Finished the 1 and 3 assembly. But one o-ring leftover. I have gone thru every possibility but cant find a place for it. There was one ekstra in the float bowl. One in air shuttoff valve. Am i missing one? Anybody?

The mystery o ring are hopefully a spare. Finished putting the pairs back together. Nr. 4 was pretty quick assembled after practicing on the other 3. Good feeling! Next is joining the halves and hook everything up.

Can it be for the accelerator pump this o ring?. It fits below the diaphragm. And there is a ring in the picture from the manual. What to do?

Cosmobiker,
See my previous reply listing all of the 'O'rings and sizes. This will help you identify it.

Yes, I got that in mind. But whats been bothering me is that I dont remember where it came from. Did I empty the bag with o ring from Randakk in my container or did it come from the carb. I got my donor carbs today and will check out nr.3 on that one.
From what ive read Im thinking better check my fuel pump before it sends contamination into the clean carbs. :)

Ok. After a severe case of manflu, Im now back on my feet.😊
Thinking everything is in right place on carbs.
Got my donor carbs and the floats were fine. So my original set is now almost read for testing.
Of course 30cm of snow overnight.
Got a new used seat also that seemes to give me more space.

Carbs are now completely reasembled. When I got the bike I noticed that it started to drip from the gas pump. Between the head and the pump. Mix of oil and gas it seemed. Took the pump off now. Looks like gas inside the lowest housing. Is this possible? Can gas leak thru the pump and into the engine? The diaphragm looked cracked and very stiff when I streched it.

Yes, you can get a pinhole or crack in the pump diaphragm and it will pump fuel into the carburetors and also the crankcase.

Took of belt covers, pulled plugg and took of rocker covers. There are gas in the engine at last around the gas pump. Should I Just drain the rest of the oil so its not sitting long in engine? The timing marks were corect. Next is checking walve clearanse. I can see that my waterpump ha red plastic impeller. Think I read that this was not something to hold on to. I ned to rebuild this to sine it started to drip from the weep hole. And then I might as well change the whole pump to. At lest I will get a reliable bike with rebuild carbs, New fuelpump, New waterpump and new belts


. I have also new plugs, wire and caps.

Gas in the oil won't hurt anything while you are still working on the bike, it might even dissolve some gunk out of the crankcase while it is in there.

But before you are ready to put the wing on the road for a drive I would drain and replace the oil with some really cheap oil, drive a short distance, maybe 30 mi (50KMs) or so and drain/refill the oil again, this time with good quality oil.

Reason for this is there's about a litre of oil in the back of the engine that doesn't drain out when you remove the oil drain plug. I found this out the hard way after removing the engine to replace a burnt-out stator. When I removed the rear clutch/stator cover from the engine I was rewarded with a very nice flood of oil on the garage floor......
