you might be able to, the air filter wouldnt do much but if you did the ehaust right you could gain about 40 percent hp. If you just modifi the muffler it came with (visit www.thatsdax.com to see how to modifie the muffler) you can gain about 1-2 hp.
Hi to all , I did that to my muffler and it did indeed pick up some power and its only a little louder. I think maybe 1 or 1 1/2 hp gain but not much more. Mike at Simpsons motorbikes has a more tuned exaust you can buy that should make a bigger difference if you have the cash. He also sells carbs and some carb parts and soon will have the elusive 36 tooth sprocket that will allow for speeds in the 40 mph range.I plan on getting the sprocket when they come out . That should be a blast to cruze at 35 - 40. Right now mine will do 35 but its crusing speed is more like 25 - 30. Well good luck whatever you do .......Tom in VW
you can pull that lie on the facebook groups all day (and I know you do, I've seen you do it a hundred times), but people here know better. not a one of your crew is breaking 70. not many are even breaking 50.
The hp carby on eBay for a 66cc comes on a pocket bike the muffler on the pocket bikes are thin metal and small diameter I tried some stuff then just put the hp pocket bike motor on my push bike hits 50 kmh likes to lift the front wheel if I lean back no peddling. like a drag bike but only to 50.
