Re: Still getting really bad gas mileage.
Do a plug chop!
When does it 4 stroke? Partial throttle or full throttle?
Did you change the spark plug to the NGK yet?
Also, are you shutting the fuel off when you aren't riding it? I didn't do that on one bike. I also parked it over grass. The tank would drip dry in a day or 2 and leave me wondering why I got such bad mileage. I parked it on pavement once and saw the drips... suddenly 2+2 equaled 4 and I felt like an idiot.
