2010 CFMoto Jetmax 250 Scooter

[bikerdoc]

Dear Bikerdok,
Have you reached 30000 km on odometer?

Have completed approx. 28700km and about to fit my third rear tyre with the last rear tyre being a Kenda (from Taiwan) performing quite well but only lasting 6000km - around half that of the standard low profile radial tyre supplied by CFMoto. My front wheel is on it's second tyre. Have been having some issues of late with starting from cold, but not sure if its the high humidity or high temperatures causing some issues with EFI/ECU, the air box/filter, or it could be just the higher moisture content in the humid air allowing for my condensation and therefore water to collect in the fuel tank/system although I think it's related to an after market muffler I've fitted bought via taobao for cny100 which also backfires through the exhaust a lot on deceleration (indicating that fuel/air mix is running to lean - which given fuel injection and ECU management I'm not worried about playing around with). The muffler is louder and thus provides less back pressure, and since I doubt that there's any decent motorcycles mechanics with a dyno-jet or the like to calibrate the new muffler to air/fuel mixture and the EFI wizardry -it's a no brainer.
Am looking to have a better after market exhaust fitted, perhaps a Lazer muffler for a Tmax, though if the gains are not worth it, I might just go back to the standard muffler.

I'm still fairly happy with the scoot.
