Jets for a good price
I had the wrong size of jets which made my banshee run very bad until I bought some from here. They work good and affordable.

Good jet / good price
Nice to have, spent a lot of time adjusting the carb and now the bike runs and starts easily. Definitely worth the cost and effort to adjust the jetting.

Great Deal
Same quality as OEM, perfect fit, gets the job done without braking the bank. Another thing they offer more options in sizing than others.

installing on a bike with x2 carbs, do I need to order x2 of these main jets?
A shopper on Sep 26, 2019
BEST ANSWER: Yeah, if you have 2 carbs you'll need 2 jets. Do you know if your jetting is on the rich side or lean? You might want to order at least 1 additional step in case 1 isn't enough. For example, if you currently have a 280 main and you're running rich you'd order a 280 and a 270. If you did that you'd be ordering a total of 4. If you're running lean you'd go in the other direction. Hope this helps.
Are these jets brass?
Braden T on Sep 27, 2018
BEST ANSWER: Yes, these jets are brass.
