I just ordered the proflow foam filter and I'm wondering what jets to get I live in MN I would say about 800-1000 ft of elevation do mostly trail riding and gravel pit climbing so any info would be useful the machine is stock right now with the ideas of a slip-on at a later date. Thanks again RY

 

If you leave the lid on I'd say stay at what you have or go up just one size. Stock is 140 left 145 right. 145 left and 150 right would be the next step up. JMO

 

get a few differant sets each bike is differant you will have to mess with it to get dialed in

 

Thanks for the info

 

I would not stop at just getting the pro flow foam filter. I have the same filter but I A. removed the snorkel B. cut a huge hole in the lid and then epoxyed a water resistent outerwears over the hole. C. Installed a stage two dyno jet kit placing the dynojet brand mains 148/150 respectively and set the new needles at the #4 slot. Turn the fuel screw out three and one half turns out from all the way in.
From my experience I would say I got about four extra horse power across the board. Or let me put it this way(with stock pipe on before and after) before the mods I could yank a third gear wheelie on the sand flats. Now I can yank a fifth gear wheelie on the sand flats. No doubt about it, more power.
P.S. My set up is for below 2000 feet above sea level.

 

yeah I'm holding out on the filter thinking of getting the pro flow kit with a slip on the conditions I ride are always dusty not sure if I want to cut holes in lid and just wondering which slip on should I get that is not to loud I heard a 400ex with the lrd full system and it was way to loud I plan on going to the dunes (silver lake) maybe this summer and they have been checking db all the time plus I always ride in and out of a resort and I don't think they will like the noise so right now my hands are tied not sure which one to get and wherer can I get a good deal on line atv shops in my area order every thing and have extremly high prices just looking for a deal Thanks in advance RY
