i have 3 questions.
1. im getting a rse reed valve for a grubee 48cc. i know that i should drill holes in the piston skirt on the intake side to extend intake duration for any kind of power increase with a reed valve. but instead, can i raise the piston skirt and lower the intake port to achieve the same affect? source: http://www.dragonfly75.com/motorbike/reedvalve.html
2. according to the link i provided, i can take 5mm off of the skirt and lower the intake port 5mm for a total of 10mm. is 10mm total too much or too little or just right?
3. after all is said and done, i know i will have more power, but what will all this do in terms of fuel economy?
