the CDI on the 08 650 is way retarted for any hi altatude use 5000 ft or more . you can here the valves trying to breath just like those old low compression chevy in the early 80's , at least that's the way my 08 runs here in colorado . ???? has anyone elese had problems with there frount shocks , mine are weak and one leaked at 250 miles of use and of course it was out of warranty not that I would replace it with the stock junk . I have never seen a cheaper shock on a unit form the ????USA!!!!. CDI's, well I sure would like to know if anyone has been happy with an after market up grade for the money and from what mfg.
CDI Box
I purchased a CDI box last year and noticed the biggest improvement when starting out, seems to have more grunt to it. I own 78 acres and one trail that starts in the creek and goes right up the mountain side. Thought I would really see what improvements I would get. So first round was without the cdi box from dynatek. Seem to take a little bit for it to wind up, definitely needed that extra grunt when starting up the side where I have one creek branched over into my trail, muddy as hell, but fun going up. I made it to the top seemed to bog down in a few spots on the rpm's.
Second round threw back in the cdi box, and felt the extra grunt again, laid into it all the way up, no issues. got to the top and actually built up enough speed to where it jumped the hump at the top. All in all I would say that it was worth it. But what i do need is a aftermarket filter system. The one on sidebysidesports.com is 404 bucks. Kinda stout I think especially when I only paid 176 bucks for my teryx system.
Anyone know where I can get a good deal on a K&N Filter system or UNI, or whatever? Still shopping for an exhaust system, the prowler is the wifes toy and she doesn't want it insanely loud like my LTZ400 with a alba full racing exhaust. She and they neighbors can hear me on the other side of the mountain..

Thanks for the reply.
Is that the dynatec FS cdi box?
I recently picked up a UNI filter for a yamaha wolverine from the dealership then I bought the stock cage that goes inside to keep it expanded. "I think it was for a wolverine?"
I'll have to check but nice it is 4 1/2" od by 8" long with a opening that will accept a 2"pvc pipe.
I cost me 60.00 for filter cage and pvc!!!
I took my stock airbox off and used 3" pvc and it fits nicely into the stock intake boot then a 3" to 2" pvc adapter and a short 2"pvc to the uni filter.
I tested this set up on flat ground where I do my testing it is not a very long straight stretch but worked good for tuning in my carb after I put the Big bore kit in.
With the stock intake I was 42.6 to 42.9mph in all my runs.
When I put on the Uni filter first run was 46.4mph and ranged 46.2 to 46.6mph.
I would start from the same point and let off at, or close as I could every time.
Then machine started popping on decel. So I will wait to permanently install until I get a few pilot jets.
I am also looking for a nice exhaust but like how it sounds now.
I will probably straighten out the stock header pipe a little bit to flow better. A 90 to a 180 can't be good for flow!
Performance Mods are: 700 big bore, 1 7/8" exhaust tip, 27" mudlite xtr's, airdam fixedplate and sheve, walker evan's shocks
