As there is no perfromance airfilter on the (after-)market available, I decided to test if driving without the airfilter would change anything in the performance of the engine. Reason is that with WOT (wide open throttle) the scooter seems to be holding back. So I uninstalled the airfilter and put a nylon stocking of my wife there to prevent damaging the engine. I warmed up the engine and I rode for about 5 km with WOT.
The results are positive:
- no more gap, WOT is WOT;
- acceleration response is better (more hp???);
- heavier sounding (of course).
The results of the test would suggest that an high performance airfilter will definately improve performance. The diameter of the airintake-side of the carb is 55 mm. As there is not much room to install an airfilter I checked
http://www.knfilters.com/search/univcone.aspx to see if there is an K&N airfilter that would fit. Maybe the RC-2340...
What spark is needed after installing a K&N filter and which jets does one need to change (and where on the carb)?
Finally, would installing an airfilter so close to the tire where all the dirt comes from, be a problem?
I would appreciate some thoughts and suggestions on the matter.
