looking for upgrade parts (toronto area)

hey,
I have a F2 that I am looking to fool around with.. i still havent been able to use it yet because of the snow, but i assume that knowing myself it will not be fast enough. I think the stock exhaust is ugly as hell first of all.. i guess im really just looking for a place that sells aftermarket performance products. Such as:

different sprockets
Performance exhaust
bigger or better air filter
tires
throttle amblys
brakes
engine replacements upgrades
really anything that can improve this bike

looking for a store that i can go to physically not one over the internet.. or if anyone has parts that they are willing to sell.. thanks

Darryl
