K1100LTIC losing power

[Darith_ranger]

About nearly two years ago my '94'k1100 got power issues. I eventually found out that the intake tubes were not in the best shape. Just replaced these. Now in fairness the bike has not been that active for the last two years although i regularly turned on the engine. I replaced the spark plugs. It isn't running smoothly though. At idle the engine seems fine. But when i take it on the roads it loses power at about 2000 rpm and as i apply more throttle the rpm or speed will not increase then suddenly it will get a boost of power and accelerate in rpm and speed. At idle after one or two miles of this behaviour the idle might experience the same behaviour.

Change the air and fuel filter first.
Did you empty the tank and replace the fuel.
Fuel will turn to gel over time.

I topped up the fuel tank as needed. I used to run itat least 15-20 mins per week even when it was not on the road.

Could be that the butterfly valves are sticking. Try opening them by hand. Under load, the engine will need more fuel to reach the same revs as when the bike is standing still. Hence the difference when you rev it on the stand.

Sudden power on/off usually due to dodgy high tension electrics, in my experience.

In order to test if the hall unit or sensor is at fault. I remove the t cover, turn the bike on at
say about 2000 rpm. Appy the heat gun and notice if the power goes awol?

Took my k1100 to a mechanic. He identified firstly the idle was wrong.
Corrected that. Only two to three cylinders running due to two faulty injectors.
Also the butterfly assembly will have to be factory reset as they were previously adjusted.
They adjusted as best they could. I got two secondhand injectors which left the engine running
more smooth but still sometimes losing power 2-3000 rpm. MPG is about 40. It fine on the motorway except
pulling out of a roundabout. So how does one reset the assembly, whom does it and what is usually
the cost ?
