2007 Tomos Sprint A55
Previously stock and recently installed a K&N air filter and upjetted from 55 to 58
Lately I've been having problems getting it started after it's been sitting for a couple of hours or overnight (garaged). Sometimes it takes a few hard kicks and sometimes I need to open the choke.
Today after less than a minute of riding I heard a pop and a stutter in power. It was quick and only happened once but everything seemed fine after.
I am sure returning to the stock air box & jetting will fix my problems, but if possible I would like to make this work as I am enjoying my increased top speed and hill climb speeds.
I also have a techno hunter exhaust waiting to go on once I can mod the pipe to fit.
Appreciate any help and advice.
