No codes? If you are getting fire then fuel has to be the problem. Maybe a clogged or bad injector. Check the temp on your headers. That will tell uou if one cylinder is dead. If you temp probe a bottle of water will tell you.

i can agree with blue on this...


a great way to test if all 4 cylinders are firing correctly, would be to let the engine be dead cold (no heat in the header at all)

turn the bike on and feel ever header heat up (they should heat evenly)

if one stays cold to the touch your not getting fuel (from what you said everything else is good) to that cylinder.

It may still be firing SOME and producing some heat. You want to check the difference between the 4

common problem is to have the coils go bad.

When the bike runs like , then you should do a full tune up.

Plugs, Air Filter cleaning or replace air filter, change the oil and oil filter, put a fresh tank of mid grade gas in and burn through it and then put in some regular gas the next time.

No point in swapping grades. That's silly
