does anyone have very good starting points on jetting a 2004 eiger..my father-in law got a eiger with 26 in mudlights and he wants to re jet and put a airfilter in it. a little help here would be good..

They make a stage 1 kit for the Eiger! I did it, and it really helps!

Vroom!

I have a stock one to for my wife, so if i get a chance I'll do a 0-40 run with both machines and record the difference.

 

Before I 'upgraded' to the Vinson carb, I went with the Keihin 134 jet in my Eiger. Seemed to make a noticeable difference. Especially in the low end and at start-up.
From the factory, it was fairly cold blooded, and seemed to lack poop off the throttle.

 

The quadworks kit comes with all the jets, plus a modded needle. Everything you'll need from stock exaust to modifed from 0 to over 6000 feet.

The needle is adjustable with special washers so you can set it to the right elevation as well. The jets are Dynojets and I think I got like 9 or 12 of them all for different altitudes. One point I will make is even though you get a lot more power it also makes you machine more elevation sensitive than stock. So you should alway carry the spare jets around for different heights.

It also comes with a high flow air filter. All I can say is my Eiger really gets up and moves now. It felt a lot like my dads Artic Cat 650 at least till about 30.

I was truly shocked at how much it helped. I will also suggest you have some mechanical know-how, not that it's hard, but you are pulling the top and the bottom off the carb to change the needle and jets.

I was able to do all the work without taking the carb out. I was able to rotate the carb so the top was on the right side, and the bowl was on the left. I would also recoomend you have someone help as it makes it easier.
