Factory Jet Kit:
The usual carb jet kit from factory as config .10. I opted to not get the kit with the Ti needles since this wouldn't be a race bike and the added cost of those unnecessary.

K&N Air Filter:
Anything thje get the wheezing Fizzer to breathe better.

Vance & Hines SS2R Exhaust
A nice looking full system, and one of the few full systems I was still able to get for the Fizzer. Pipe shines up great with a bit of Mothers polish and is a nice oval shape to allow better ground clearance. Th sound isn't too bad either.

Ignition Advancer:
A +5 degree ignition advancer, aids in throttle response. Usually gives a small bit of hp.
