That's because I have ordered the big-bore upgrade kit this week. I'm anxiously awaiting for the arrival of the big brown truck leaving goodies on my front step. The kit comes from Power Sports Factory. It includes everything I need to make my scooter into the real 150cc that it should have been from the factory. There is a new cylinder, piston with rings and pin, a new cam, a bigger carburetor, air filter and inlet tube. There's also a new variator which is the portion of the transmission that adjusts for the gear ratio change.
The only thing I didn't buy from PSF was their exhaust pipe and muffler system. Instead, I'm doing my own high performance system. As mentioned in the previous post, CPI Racing is going to build for me a new exhaust pipe to fit this megaphone muffler from JC Whitney. The original exhaust pipe seems to be terribly restrictive and not conducive to making power so the new system should be much less restrictive. I'm lucky that CPI is just a few miles from my house as it will be neccesary to haul the scooterdown to them for proper fitting once all the parts arrive.
Needless to say, I'm might excited about the new parts and expectant of lots more power for my scoot. And the way the weather's been going, riding season won't be too many more weeks away.
