I Need to know how to get to my Carburetor properly and clean it as my bike won't start properly, it tries and back fires but wont run. which is the correct procedure to get to the carburetor and the best way to clean it?
You actually have 4 carburetors on that bike. Remove the bodywork, the seat, and I think the fuel tank has to come off, then you should see the four carbs. Best bet, take it to a dealer and have them do a tune up, they will clean and adjust the carbs as part of the service.

yes sounds like carbs need to be stripped and cleaned once that's done and bike ok you better off putting an inline fuel filter on bike stop any debris going in carb again , filters are good for about 1000 miles so worth putting one in
Hey Cody,
>>> DO NOT "BOIL" a carburetor... that is NOT HOW YOU CLEAN A MOTORCYCLE CARBURETOR!!!!!!!! That is an old school, RED - NECK, backyard, UNQUALIFIED way to ATTEMPT to clean a carburetor!!!!
Take the carburetor to a QUALIFIED PROFESSIONAL motorcycle mechanic and have him clean and set your carburetor!!!!
Yes, it is a carb problem. The carbs need to be thoroughly cleaned. It won't idle because the slow speed circuit is gummed up. The back fire is a situation where one carb is driving another. The best carb is driving the engine and the worst carb is running rich. This imbalance causes the backfire.
It sounds like the jets in your carb are stopped up. It could be any one of several things but the problem is in the carb. Cleaning the outside of the carb makes no difference, you must remove and clean out the main jet and the slow speed jet. Also you need to check the operation of the accelerator pump. Even spraying carb cleaner inside the venturi of the carb does no good, the carb needs to be completely disassembled and cleaned. To be more specific, I'd need to know exactly which carb is on the bike, keihen butterfly, keihen CV, or aftermarket.
Does the bike have a good spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Is the handlebar kill switch on? Check the fuses. How good is the battery? Try a jump start from your car battery. Check the operation of the ignition switch and all kill switches with a volt ohmmeter.
If it does have a good spark then look at the carburetor. ALWAYS have a fire extinguisher on hand when working on carburetors. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). 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. Install a new stock NGK spark plug and try to start the engine. 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. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well. < < READ CLOSELY > > Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Post a comment to get back to me.

Put the rest of 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.

needle and seat are worn out in carb, to much fuel is flooding cylinder. remove carb, clean, get new needle and seat, set float. problem goes away. pull your plug after kicking. its probably wet.
When you push, or pull start you evacuate excessive fuel, when engine is warm, easier to start extra fuel burns easier.
