well I did a deeper look into that giobikes site and they don't seam to have much performance parts for the gy6, or if they do they don't mention that it works with gy6 :P and they don't seam to have any jets. :P
I was thinking I'd also try the higher rpm spring, rollers, and no rev limit performance cdi along with the jet, and being able to get all these from one place would be a bonus.
Do you know of any other canadian retailers that would sell this stuff? Too bad there wasn't a canadian version of that syc powersports thats in the banner on the top of the page. They seam to have everything I would need and more.
As far as checking our local motorcycle shop, sometime soon I have to get around to taking my motorcycle in for servicing, so I guess I could ask them if they have jets while I'm there. I still got another week or 2 to wait before my filter comes in so I'm in no rush, maybe I'll find something by then, if not I might just try drilling out the jet to a good size. :P
Thanks for all the replies guys. =-)
