Question about Motorcycles
Crashed dented tank problem started then cleaned fuel tank carb no more crapp in gas problem still back fires
This could indicate a number of issues especially with a unit of this age. You stated that the problem started after the crash. Have you done a proper job of carb cleaning and reassembly( check for blockage in the main jet circuit as you state that it idles properly as well as proper fuel level in carb bowl). back firing is a symptom of a lean condition- lack of enough fuel. Also check for air leaks around the carb manifold and the vacuum hose circuit to the fuel petcock. This can be done by spraying wd40 or a carb cleaner around these areas while idling. A change in engine rpm when spraying indicates a leak. Another possibility relate to the crash may be ignition wiring that got chaffed, shorted, or otherwise disturbed such as a rotated switch housing during the crash which is now causing a short. Inspect the wiring GOOD in a dark enviornment while the backfire is presenting itself and look for arching. I hope this helps!

Clean the air filter and, if you have one, remove the water trap bowl on the fuel petcock and clean it. How good is the battery? Install new STOCK plugs. Bear in mind it may be time for carb kits. Other than your cleaning the carbs, the carb kits and balancing and synchronizing of the carbs are best left for the shop to do.
Check the exhaust pipes. If there is a restriction in the burned gases exiting the tailpipe then the bike will not run right, will loose power and even die if too much back pressure builds up. Disconnect the exhaust system and tick off the neighbors with a quick ride around the block without a muffler. If the engine still dies then exhaust is not likely to be the problem.
Check the compression on all cylinders. Depending on the compression, the bike may be ready for a valve job. If you pull the head for the valve job then you might as well consider re-boring the cylinders and install new pistons and rings. Bear in mind, doing a valve job and / or pistons is not recommended for the novice. The good part is that when the work is finished you will effectively have a new engine.

SOURCE: kawasaki 300 bayou won't rev up.
No guarantees but try this. Pull the slide from the throat of the carb. Now move the clip on the jet needle down one notch. This will richen the low end mix. Two notches may be needed but do one notch at the start.

it is possible that th eplugs might be fouled but it seems unlikely after only two weeks running-my fzr would foul plugs but it usually takes months not weeks-also the engine would start but run on2 or 3 cyls. I found using one heat range hotter than standard plugs helped,esp. around town you seem to have been fairly methodical on your troubleshooting-if you have fuel and spark the next thing to check is comp. -if the plugs are wet it is likely fuel not oil-when I first bought mine it had sat over winter and would not start -it turned out that the valve clearances had closed up enough that it was low on comp. when ridden frequently it was ok but as soon as the oil had drained off the cyl walls it would not start-squirting oil in the cyls. would get it started but I pulled the cams and set valves to solve problem-starts ok now but I don't use the choke-you could lift the cover and check your valve clearances -it would be a good idea on a bike that you just bought-don't give up -be methodical and check one thing at a time-when you get it going it will be worht it

SOURCE: 2002 YAMAHA BANSHEE WILL NOT REV
I have a 2004 banshee at the yamaha dealer being worked on.It would not run when i took it up there they cleaned the carbs and put it back together it will start but when you rev it, it holds itself wide open and wont shut down unless you pull the plug wires.they also checked the floats in the carbs said they where ok. they think it is a vent issue with the gas tank or the fuel shut off valve.IS THAT POSSIBLE
