Hi all. I'm brand new to this site and hobby,and based in Toronto. I'm looking for some advise:

1. Would like to change my gear ratio, go 420 12t in the front and anything above 38 for the back. Question: For the front, am i going with the 17mm or the 20mm, and also what are my specs for the rear. ?
Also, what is the best place to buy with quickest shipping ?

2. Also, gonna place an order on these, any suggestions on better option on Wheel Spacers ? ->
3. Would like a better carb to tune for air:fuel, and just better jets. Any suggestions ?

Thank you folks !

 

Any Canadian here ? looking for advise on where to buy Chinese ATV parts in the GTA.

Thx
