My 02 R6 has been sitting for the past year. I put new gas in the tank and have a new battery. It will start but when I twist the trottle it shuts down (if as it's flooded). Any ideas on what the problem(s) could be?

Flushing out fuel system , do you know what happens to gas from sitting ? Turns to varnish .

Run basic tests. Spark at plugs? Correct fuel pressure key on? Compression test?

how old was the gas in it before you added fuel. the gas that was in the tank may have gone bad.

Hi,
Is it getting gas and fire?
If so and you don't have fresh gas in the tank, I would suspect some bad gas after sitting for 7 years.
Hope this helps. Good luck!

Sea foam isn't always the answer there is far better things to use, berryman B12 chemtool is the best i have found for thing that haven't been sitting for a awhile but just need a good clean or water problems.
On to the problem at hand, has your bike sat for any amount of time? if so you need to clean your carbs. the gas will varnish and block the jet. will the bike run without the choke? Check your coilby seeing if you have spark test each hole if you have good spark them you know that coils and pickup are working.
Let me know what you find, Good luck

Try changing your fuel filter. After setting for over a year your filter may of have picked up some trash that settled in your tank. Also check your fuses you may of have blown your fuel pump fuse. Also you may try putting some new fuel.

you need to flush carb's/tank out of old fuel

if still no starts after flushing clean carbs main jets with copper wire strand

sounds like the carbs are all gummed up from sitting so long. they will need to taken apart and cleaned..

After sitting 2 years, there must have been some fuel in tank that has probably gone real bad (like shellac) and contaminated the fuel system, plugged up filter etc. Usually rust will form in tank, mixed with stale fuel, it will turn just like mud.
