1994 gsx1100f highspeed engine probs

I have a 1994 1100f it starts and runs fine a bit lumpy on tickover,after 4500 reves it starts to missfire and will not go past 8000revs.also if i am cruising at 4500revs for 5mins then open the throttle i get a complete engine miss then it tries to go but not as it should.if i am standing still i can rev the bike all the way to the max with no probs,it only plays up when ridden.
i have fitted new plugs ,balanced the carbs and fitted new oil and filter and cleaned the airfilter,i have even cleaned all the electrical connections all over the bike but the problem still exists.Has anyone got any ideas please

Your main jets sound like they too small or partially blocked with dirt/varnish. If steady cruising at 4500 is smooth, and you open the throttle somewhat quickly, it stumbles a bit, and breaks up it is too lean or the jet is too small. If it bogs, and smokes it's too rich. You could pull one of the spark plugs and check it's color. It sounds to me that it is too lean, perhaps aftermarket exhaust was fitted, and the carbs weren't re-jetted to compensate? I hope this helps.

You may be starving the carbs. I have seen this on other bikes, try running the bike with the petcock set to prime ( do not forget to set to run after your test drive ) It the problem goes away when you are riding it this way, you have a problem with and may need to replace the petcock. Hope this helps...

I'd say sounds kinda like a missfire although with the absence of an engine code I would lean more towards a vacuum leak somewhere. Chk all your lines while cars running to see if you might have a vacuum leak.

Sometimes not always - puff of smoke when starting ( light colour) followed by lumpy tickover and noisey clacky sound from engine - all becomes ok when warm


I suspect smoke is just condensation in exhaust from suiting overnight. The other descriptions sound like it needs an oil change (noisy clacky) and lumpy starting sounds like dirty battery cables - clean them top and bottom. ??- When was last "healthy" tune up? Plugs, wires, all fluids & filters? I'd start there.

Problems accelerating


the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

1998 range rover p38 2.5 dse auto engine stalls


Sounds like something is overheating then and possibly a sensor. Not familiar with Rovers but might be a problem with the CAS and/or CPS which tells the ECU the motor is running and when to fire. Also maybe the IAC is bad and when you go from throttle to idle it can't control it and allows it to die.

I have a mitsubishi l200 which runs very 'lumpy' on tickover but is fine when driving along. Any idea what this could be?


Look for a vacuum leak on the motor intake system, such as perished hose, loose inlet manifold or air intake fitting.
Check operation of the PCV valve and associated hoses.

VTEC 1.8 135K. Starts OK but feels lumpy from cold - almost like its not firing on all four. Once it warms up a bit the tickover when stationary drops to virtually zero (sometimes stalls), once fully warm...


1. My suspicion is your electronic ignition
2. If your car is a bit old, there might be a leak through your valves
3. Distributor timing gear is damaged (replace)
