Hey, well this is my first post but whatevaa.
I live in montreal, i have one of those chinese copy MT-A2 or cag bikes thats pretty modified to the max, performance exaust, delrotto carb, high tension clutch, reed assembaly, big bore kit... and i havent dynoed it but its pretty fast
For races in montreal, there are some friendly races at indoor tracks such as Circuit500 which is the biggest indoor track in north america. But there are also more championships and such around montreal. Check out
www.circuit500.com for the track and stuff.
Also for championships check out
http://www.cmmq.org/. And
http://www.quebecminimoto.com/ which is a well known pocket biking organisation in quebec.
Anyways, i hope i helped out a bit, and if your planning on getting a gp3 get it in italty caz if you plan one getting one here, you're gunna pay about the actual price of a real life size bike..
ciaociao,
underoath
P.S. FORZA ITALIA!!
