GS1000G It grumbles at 3000 rpm
Greetings to everyone on the forum.
After having fixed a GS 550 and with only 9000 km (beautiful motorbike)
it was sold to buy its father, the gs 1000 g with only 20,000 km,
the bike is perfect in every way, clearly before putting it back on the road
I carried out some small maintenance, brakes, all seals, engine oil and cardan change,
candles.
At the first start the bike ran at three, the fourth muffler cold, I dismantled the carburettor unit
to check and the fourth carburettor was dirty and no fuel was coming in, fixed!
The first carburettor leaks fuel and I think it's the float which gets blocked when the bike is tilted, as well as the fuel tap
it seems that in the OFF (PR) position it does not close.
Ok, reassembled everything after wasting a lot of time with the air manifolds of the filter box, they are a bit ruined
but in the end I put it back, these will be the next purchase along with a complete overhaul of the carburettors.
The bike keeps idling and during acceleration it seems crazy with how much it moves, sometimes I feel some gaps during acceleration, the clutch slips a bit, this too needs to be fixed, but
the problem that I can't understand and which seems to go in threes and mumble, from 3000 to 4000 rpm, below and above is fine, I also see the first muffler shinier than the others.
I thought about carburetion, but playing with the screws, first two and a half turns, then two, then one, the bike improved
under acceleration and at low revs, it starts with a little difficulty compared to before, but the problem is still the same,
from 3000 to 4000 rpm the bike grumbles, so even if the carburettors need cleaning and overhaul, I think it's not them,
otherwise by acting on the fuel screws something would have had to change.
I understand that there are many variables, but I wouldn't want to go to the exclusion of changing everything!
I rely on someone with good experience for advice on what may have happened,
thank you for your patience and for the not exactly perfect English
