That's the problem that's not the jets mine has it just a knock off I guess this sucks I paid for jets that didn't fit already I don't want to do it again
 
Did you pull the jet out of your carb and measure it? Too many new guys buy off market carbs and just expect them to work. Run your standard NT carb until after break in, then you'll know what to upgrade.

Most jet sizes for NA run from 62-82, anything outside that is a waste of money.
Check with this guy, he's been trying to close down shop and might have the jets you need, cheap.
 
if you got steady hands you can get micro bit sets for a cheap price and do it yourself

Take your jet to your local M/C shop (dirt bike shop) they have a whole box full of assorted jets that they have collected over the years from tuning up bikes. They'll probably have what ya need or be able to get it for ya.
One jet they'll probably just give it to ya if they got it,
But be :cool: and offer to buy the guy a soda or lunch, and toss him a $10
It's always good to have friends in the right places
