Try dumping your gas tank and refilling with fresh gas.
yeah i might do that, well i bought new spark plugs already anyways... i needa take the tank off in order to get to the plugs, so i guess ill just do both since tank is off anyways?
oh any good recommendation for injector cleaner?
and Weebel, no, i have been riding it for short trips (15mins ish rides) around my neighborhood running errands at least 2-3 times a week, so the bike gets its regular runs. i got new engine oil and oil filter today, and still sounds same, i've asked the guys at the shop too, he says i can try changing the plugs and see how things go, got 4 ngk iridium X just now.
yes sometimes, but when yeah its more and more obvious that its misfiring today when i was riding, didnt get to ride it much the past few weeks
Have you checked the exhaust? I had a similar problem a few years back and checked sparks and carb all fine... it was only when I putting the carb back together that a friend of mine suggested running some petrol through the exhaust can I realised that it was severely clogged and that was causing the problem.
Also check for rust and/or any holes particularly around the head where the exhaust connects to the motor.
