Rejet and air filter.
Hi I work on my vtr's carb jetting right now (factory jet stage 1) and might as well i also want to replace oem air filter, but searching about K N air filter seems like that are alot of isues w/it. So what you recommend? Stick w/oem install new jet kit or should i go w/K N a/f? And what is base line? I believe someone member of this forum talk to VTR guru and not recommend to replace it w/aftermarket air filter
Thanks Gents for helps and advices.

I think you could go for the K&N and be successful.
Go for 2.25 turns on the mixture screws
needles with the clip in the middle (3rd) notch
182r/180f mains (185r/182f if you're feeling frisky
)

im running K&N with D&D slipons at about 3000ft elevation
jetting is 48 pilots 3 turns out (2.75 woulda been perfect but im to lazy to pull the carbs again for that.) with 190r/185f (i only had steps in 5) also if u r going to stay with the stock size 45 pilots you should get some non 'S" varients. they hav larger air holes and make the air and fuel mix better.

I don't have jetting advise other than saying it's advantages might not be worth the trouble. have you researched what the hp gain would be? anyway I am curious about your location. I'm in Aurora. how far from bloomington is that? I don't see many other superhawks out this way.

I don't think they sell them anymore, mainly due to the hazardous material concerns of mercury. You can try Googling Twinmax. That's a very good unit I've used in the past, though I do not own one. Only works for twins though. They may have another one for IL4s, or you could just switch out tubes.

i am running a DJ kit with 48 slow jets. had to order them seperate.
for the choke piecies i aquired some brass ones out some mikuni carbs that fit in place of the plastic one. polaris uses them on the 400 scrambler cars. posibly others but no garuntees. if u hav a polaris dealer getting them should be easy. you will hav to drill a small part of the brass out.. very easy mod to get choke inserts that dont break anymore.

Guys...good evening,
I just purchased a set of Akrapovics.....full system, racing line. Would anyone happen to know what jets I need to purchase for this setup? I plan on purchasing a K&N air filter, unless I'm told I should go another route. Any ideas? Thanks.

A few weeks ago I dropped in Two Bros. Slip On's and a stage one jet kit. I justed dumped a K & N in her this week, and it did wake her up a little more. Just put a few hundred miles on her tonight going to the Americade, and there was a little more there after the K&N. I'd recommend it....
