Pro motor mods, whats everyone running?

[pj8556]

Hey I just bought a '13 Pro 800 LE, looks great excited to ride it, thinking of doing some mods. Leaning toward RKtek piston/head, HPS can, Carls clutch kit (or whatever RKteck recommends) possibly Team tied secondary too. Gonna balance and shim (if needed) the primary. Was gonna swap the track for a CE but now I think I'll give the 5.1 a try and trim it if it ends up being too soft for my prefernce.

Anyways, I'm interested in what everybody else is running or gonna run and why?

I have 2 '11 Pros and a '12, I will leave 2 bone stock (both have a 4 year warranty), and the other one I totaled and bought back, but messed up and let warranty slip. For that sled, I put a 155 Camo Extreme track on, Team Tied secondary, Raptor front shocks and rear springs, and just pulled motor for a Fuiji crank and RK Tek 858 kit.
The Camo track trenches like a mother, but is super fun in the spring/Hardpack! Last year we got some DEEEP powder storms, and the Camo track made the sled worthless (my girlfriend chicked me baaad on a stock '12). That being said, I put 800 more miles on the sled with mods over my stock '11...
With the Camo track on, the secondary was a great mod, but I would probably recommend suspension over motor work if you have warranty. I lost a motor on my '12 last year, and warranty was soo nice to have!
There is also a flap valve for the intake that will draw air over the motor if your filters plug. Works like a charm, but might void warranty...

Carls cycle porting, head, pipe, fuel mapping, clutching, clutch balancing and resurface, carls redo valving of all shocks, carls recomended venting, cat track.
Because what those guys say works, day in day out, gas and oil, pull the rope and put a huge smile on.
I use carls because they make the best motor combo's, clutching combo's, handling combo's for a Polaris IMO hands down. You know when you get it from them its gonna work and be reliable. They test there stuff alot before ever releasing it to the public.
Call them for your pro you wont go wrong!
