I would like to get more power without replacing the carb or rejet. I tried removing the 4 hole air cleaner plate and bogs. Too much air i guess. What about adding one more hole?
And the muffler....can I drill a hole or two to get better power and live with stock carb?

ANY changes to airfilter or exhaust require rejetting . I took off the airbox lid for laughs and it bogged so bad I did not leave my drive way . Jets are a few bucks , a carb can be as little as 26 dollars but it better one more and roller weights are cheap . It is not starving for air like it looks like . 2 3/8 holes can yield more flow but you will need a larger main jet . Lighter weights can bring the RPMs up and yield more speed or at least on take off and uphill . Too light it over revs and looses power . Some a heavier weight can yield more top end . It depends on your gearing and how many RPMs it can top at before testing other weights . Many use 5 grams in the 4T 50s

 Changing airflow in any way will reguire rejetting. If you know your way around a scooter motor it shouldn't take longer then 10 to rejett from start to finish.

Simply clap the fuel line , unscrew the drain plug in order to drain out the bowl . Then unscrew the bowl and jets are like a hollow screw easy to install . Main jet , lighter rollers is the cheapest and safest mod . To truly get more power you will need a BBK Now you can checkfgor restrictions like the variator washer here www.provoscooter.com/variator-deregulation more tips www.provoscooter.com/tuning |

All good advise but was trying to get around trashing my new stock carb that anti tamper proof.

Lowes $4  Be careful, you go to much and you will be soldering up the hole and starting over. You only have to go alittle with this thing. |

Feeler gauges?
Also, there isn't one restriction on this bike..checked everything.
