Jets alter the amount of fuel into the carb. After studying the large horsepower claims of other kits it is usually determined that some or all of the following had been done: 1 airboxes where cut or modified and 2 engines had been modified with cams etc and were not stock and 3 exhaust added, etc.
Why do other kits sell jets that are smaller than the stock jets? Smaller numbered jets are "lean" jets made for high elevation mountain riding. Many kits are mass marketed to appeal to everyone. The Jetsrus kits sold here are made specifically for high performance aftermarket parts. If smaller jets for high altitude riding are needed we can provide them. Some kits don't list the jet sizes in their kit, how do I know if those kits will work for my engine?
If the kit doesn't list the size of the jets it contains there is no way to determine if those jets will work for the application. Always determine the size of the jets in the kit you buy. Other kits indicate they are for different stages, what stage are these kits? The designation of stages can be misleading as the stages overlap each other. How is a "stage" defined? It is marketing hype. The overlap of the stages makes defining whether a kit meets a certain stage ambiguous.
There is a description on each Jetsrus jet kit page that indicates what each kit is for. Do you offer needles? If you want to adjust your needle and it is the non adjustable type the most economical approach is to place small washers under the c-clip to raise the needle. How can I effectively rejet if I don't know where to start? Lets use an example: A slip on pipe and an aftermarket filter are put on. The stock main jet is and the stock slow or pilot is a The engine runs poorly at wide open throttle and backfires when backing off throttle.
The backfiring can be fixed by going to a larger slow or pilot jet, in this example the next size up is Both sizes could be purchased to get the low end of the carb adjusted.
If the low end is still performing poorly the next bigger sizes could be purchased later. The main jet affects wide open throttle but it is hard to know what sizes to guesstimate, a , , , , would be good sizes to try. If the is too small and the is too big an in between size may be purchased at a later date to get it dialed in perfectly.
Remember the extra jets that have been purchased are not a waste of money, when the temperature changes or if there is a trip where elevation changes those jets will be used. Does needle jet affect idle? How do I know if I need to Rejet my carb? Can you drill out carb jets? What does Rejetting mean?

My stage 1 worked pretty well on my pre , not perfect but pretty well. Hemi your avatar is killing me.
I love how the most ignorant people I have met are the ones that fling the word "ignorant" around like it's an insult, or poo. Maybe they think it means poo. I was gonna go with the stage 1, figured i'd ask first. Awesome replies, cleared everything up for me, thanks guys. The needles are the same no matter what. It's even tougher when you're stupid!
The jet variances is a given. As of now, i know i have something other than what the bike originally came with- but i have no idea WHAT. If i buy a kit, i know what it will BE.
