Sounds like either the timing has jumped, the stator plate is loose,or the reed valves are bad.More likely the reed valves.

Please take time to rate this fixya

    If it is back firing out the carb,It is the carb that needs repair.

    You can also check the following,

    1. Check that the timing is set correctly

    2. Check that the carb jets and vent are clean (This is the most likely cause)

    3. Check the reed/power valve

    4. Check for proper power and ground on the coil and cdi.

My 1990 Yamaha blaster 200 starts and idles fine

Could be several things, but lately half the problems I run into these days is bad gas. Be sure to use ONLY alcohol free premium gas NO ethanol. Gasoline these days is only good for a couple months at best, so drain out every drop you can, there's even a drain screw on the bottom of the carb. Fill it with good fresh gas, an ounce ot two of "sea foam" or a quality fuel conditioner. With luck it may clear out the problem, if not then I'm afraid your carb will have to come apart and be cleaned, but it's worth a try first.

I changed the plug cleaned out old gas put fresh gas through it. It doesn't backfire under choke, but when you take the choke off it backfires

Sounds like you need to service the carbs as it sounds like your bike is starved of fuel with the choke off and some of your jets may be blocked.

2007 yamaha grizzly 660 backfires when you let off the gas what causes it

Backfiring is usually a result of the timing being incorrect, this can also be a result of a bad valve.

I have a 1988 dodge ram it wont start it will start on primer then shuts off i replaced the fuel pump and filter but still wont start could it be air locked can you help me please thank-you william

Sounds like it's fuel starved. It will be TBI, there's another fuel filter bolted to the chassis, about mid way, drivers side (looks like a small metal can, with to hose fittings). Any fuel leaks anywhere, rusted out fuel or fuel return lines? Air starved? Replace your air filter. A bad coil will cause this too.
