Possibly but from you description I would be looking at a condenser failure ( not allowing full charge for the coil)

SOURCE: '03 gsxr 600, rusty fuel tank n rough revving

carbs need a good cleaning. had this same problem with an 82 GS1100. cleaned the tank as best i could, you can never get all the rust tho. finally had an idea to place a couple of old car speaker magnets on the outside bottom of the tank to catch any residual rust. been 4 years now with no more problem.

Sounds like water in the gas. ALWAYS have a fire extinguisher on hand when working on carburetors.
For each carb > Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb.
Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Please rate this solution. Thanks!

big spring is for the dighram! the only other wouls be for the pointy mixture screw
Cheers Rob
wind the screw in till it just stops [not hard]
then wind out about 1 & 3/4 turns that should be a close air fuel mix then adjust idle & mix till you get it right
Cheers Rob

I have a 1997 lumina with 3.1L. the problem started with loss of power under load and p0300 code. check coils and vacuum leaks both OK.change spark plugs and wires.[same problem] check compression OK.


Since you changed the sensor we will assume it is working. When you disconnect it you put the computer in limp mode which stops it from using sensor values. If code 300 is the only code we will assume the coolant temp sensor and others are ok.
I would check fuel pressure with a gauge next.

Engine starts fine idles ok has very poor throttle response and valve train noise. i suspect timing belt(s) but am unwilling to go to the expense if it is an interference motor. Is it? Suggestions?


If it hasnt broke yet then no damage is done. If you wait for it to break you could destroy the engine. As far as your complaint, if nothing has been actually tested then there is no way to know what your problem is.

I recently purchased a 2002 lowrider with only319 miles on it obviously it has sat awhile. It has a hard time idling on initial warm up and when warmed up giving it a little throttle (not under load) it...


The bike may suffer from a combo of the gas going stale in the carb, and may have slightly clogged the small passageways, but if it starts and runs you are halfway there. Use some carb or fuel injection cleaner in the gas tank to help out there. As far as cold start, it may be from a lean condition form the factory, and the coughing and popping are symptomatic of that. If you have a good HD shop nearby, they should be able to change the slow speed up just a bit, to pretty much take care of the issue of coughing, popping and cold start issues. My bike was the same, I bumped the low speed jet up , but still have a cold blooded bike, it takes a while to run properly form cold start, and will pop if driven too soon or if it is cold out until she warms up good. Some advice for cold start, use the choke know as usual, then push in the choke as soon as you can, and use the throttle to keep RPMs up about 1000 using throttle lock to RPMs there. As the motor warms up RPMs will increase on their own and you can adjust the RPMs lower as motor warms using throttle and throttle lock. Use your hand to touch the heads, as the motor warms up you'll feel heat, when she's too hot too touch, she is ready to ride. See you in the wind.

Poor idle


It sounds like you have to take your carb apart and clean it or you will possibly need to rebuild it.
Make sure your air cleaner is clean.

My 125 maurauder starts and runs idle great as soon as i turn the throttle (not even in gear so it isn't the sidstand cut out switch)) the engine cuts


If your bike has ever been sitting for more than six months to a year, then the carburetor is likely clogged with fuel varnish and needs to be disassembled and cleaned. If the throttle response is improved when the choke is applied, then the carb is plugged for sure.
Sometimes, if you're lucky, you can simply drain the stale fuel from the float bowl and see an improvement. I would try this first, because it is possible that some moisture has collected in the carburetor float bowl and is causing the poor throttle response.

Engine shuts off when rolling the throttle


They could be related - but what you need to do is first clean out the oil that has collected in the air filter housing - and replace the air filter. Then, clean the oil from the engine - Simple Green and an old tooth brush works great for this. Wash the engine and surrounding areas with soap and water.
Now, with things cleaned off, you'll be able to tell where the oil is coming from after a short test ride. It could be that the oil you saw near the head gasket was actually running from the air box. Hopefully, a new air filter will cure the problems you had with low power and poor throttle response.
