my dealer gave me the deer in the headlight look when i asked about rejetting for better performance. can anyone help? 00' 500 sportsman. thanks.

 

Why do you need to re-jet? Be specific.. Is it stock or have you done mods to it?

 

no mods, just want to know if there are noticable gains in perf. by rejetting.

 

Hello, I put a K&N Jet kit, filter, and HPD clutch kit in my 00 sportsman. Gained 5 mph, much better accleration, and more power in mid range. Cost about $150. Did it my self in about 4 hours. Let me know how it goes. (Just to let me know, with this set up, I was able to out perform a Remington Sportsman 01 HO.

what size would I need for mine? '01 sportman 500 H.O. K&N filter hotseat performance clutch kit and their full exhust system. No airbox mods. oh ya I'm at sealevel

 

When you purchase the K&N Jet kit, it comes with multiple jets. The climate and feet above sea level, determines the jet you will need. There is an easy table to determine the size.

carver,
you can pick up a little by rejetting..is it worth it, I say not really...

BUT if you modify the intake & remove restrictions, do a mod on the pipe, or aftermarket pipe, well then, yes, it is needed, and is worth it..

I have 2 street bikes, both of them have had airbox mods, K&N filters, (less restrictive) amd muffler mods, both have had jetting changes to them.. on the small one, I went from a 95 main to a 120...

on the large one I went from a 90 main to a 117.5 main..

both of them went up 1 size in pilots..

the prarie has had airbox mods, & free flowing filter, I went up 1 size on the mains without a muffler mod..

so jetting by itself really is not the cure all some think it is.. look at it this way..an engine is a air pump.. it takes air in through the airbox, mixes it with fuel, & it goes out through the exhaust.. if you change the airbox, you need to rejet to get it back in balance, same thing for the exhaust..

I did jetting changes with stock jets..I did'nt like the needle in the kits, it was cut on a strange taper, & with stock I knew what I had & how to modify it to go where I needed to get..

but what you pay for in a jet kit is the time it takes for someone to put it on a dyno & test it to get you close.. the parts are minimal..
be advised that dyno jets are rated by the diameter of the hole, a 120 is 1.2mm, mikuni, kehin is based on flow rates, and are not going to be the same size.. a 120 mikuni flows more than a 120 dynojet.. will they both work? yes..

hope this helps..
