I still have a 03 pro x 700, one thing that I would do, if it hasn’t been done for a couple of years is have all of you’re shocks serviced, most people don’t take care of there shocks, fresh oil and a fresh charge is a good way to start the year! Also make sure all of you’re suspension fasteners are tight, not just the tunnel fastener but all of the rail one too! These sleds are tough but need maintenance! Enjoy!

Checked all bolts on rear skid yesterday all are tight , the edge fts spring didn’t show up yet , took 14 turns out of front ski springs and about the same on the fts to get about 1/4 inch preload ( they were really cranked up ) I did do the roller mod to the rear springs and adjuster on high ( now I only pull it up about 1/2 inch after getting off sled , still needs rear springs replaced ,

Ordered a progressive ( edge ) front shock spring To replace the 160# or 190# one
Doubt very much going from a straight rate 160# spring to a 150/175# rate you'll notice much of anything. Its too bad the prox front torque arm doesn't have a 2nd top shock mounting bracket like the edge front torque arm where the shock can be mounted to lay more forward giving the sled a softer ride, and better handling for lighter riders. you combine that with a dual spring setup of the right rate springs, and re-valve the shock to comply, you'll have a nice riding sled plus it'll handle even better on the trails. Not everyone wants a suspension for snocross unless thats the plan.

thought I read somewhere. Think it was ( alsled ) said the edge 150/175 progressive spring don’t get scared by the #s. It actually works out to about 80 something up to 175 , Will try it once I get it , hope it works out , but worse case will try to find think it was a 120# straight everyone was going to

Our guy ran a straight 140# in his 03 700 prox back in the day...said it was better than the oem spring when we did a multi-day bag ride with him, and this guy had to be pushing 250 lbs..

Trying to decide if I should put in the 1 tooth lower gear , and leave stock helix , or get that helix also , or leave stock gear , and get that helix
I'd put in the 24 top gear, those sleds were geared tall like mentioned before. Also agree that the pro-x will struggle on the lake as the rear skid robs some top end. But get the suspension dialed and it will be a delight in the rough

trying To put together a perc setup fo it , read a bunch here about it. , found some of the parts just not 100% if they are correct, prox700 build date 10/9/02 , noticed when I changed the tach bulbs that it has the wire for where the perc/reverse light would be ,tach just doesn’t say reverse , thinking hood wiring doesn’t need changing ?????, can I just change the short harness from cdi ????
is list below correct ???

4010874. Perc button
4010872. Edge/rmk cdi perc harness
or
4010811 Edge/rmk cdi perc harness
or
4010661. 2003 edge classic 500/700 cdi perc harness
4010987. Cdi Was told it’s a 2003 700 Xc/prox cdi with perc nos

or would it be easier to get all the stuff for a 04 with det and if so could I connect the det and just wrap it up not connected to motor , or just find a spot and bolt it to motor ????

thank you for any help

I put in perc on my gf's 2003 xc800. Found a kit on ebay, cdi / harness / roller sec.clutch and left handlebar switch assy,

edit: confused this with another thread. You sled should have a roller clutch already.

also, if I'm not mistaken , the rmk's got a slightly different timing curve than the xc/pro-x...?

If you can hold off a day or so I can get you probably all the part numbers you need, I keep all the paperwork for my sleds, I installed the kit so I should have all the part numbers to hunt for!

You will run into some snags with PERC because some of the parts aren't all that available anymore. The '03 sleds didn't come with PERC, it was available as an accessory kit. The '04+ sleds came with it, but had DET. The only parts you REALLY need are a PERC CDI and harness for it, plus a reverse button. A reverse compatible oil pump would be good as well. The original pump will pump oil "backward" if run backward. If I recall right, the hood wiring is OK, but the harness under the engine is short a wire to operate the "reverse" lamp in the guages. I've strung the "extra" wire through the corrugated loom and patched into the connector at the base of the hood. For the reverse button, you can use the one from the kit if it is available. Another option is to dig in the race forums and see if anyone has a "dragon" button available from an IQR. Same style button, just have to patch wires into the right places on the chassis harness.

Regarding what parts you could use, I think your numbers above are OK. For CDI, another option is the 700 SKS/RMK - 4010989.

Just an FYI, he would need CDI 4010987 according to Polaris, that’s what I show on my installation sheet that came with my PERC kit.

Info for the future.

Yes, the 4010987 is the CDI used in the Pro-X and XC kits. I was mentioning the RMK/SKS CDI as another option. Some of these components aren't going to be available from Polaris. The only option may be the used market, ebay or similar. He may have to take what he can get...

FYI for everyone: I did make an error in my previous post. The 700/800 engines in '03 already had the PERC compatible oil pumps. The 500/600 were the engines that didn't. My bad....

thank you for your help , from what I can find it looks like I could do it without the main harness , looks like the harness in the kit has 1 or 2 extra plugs , I would have to run 1 or 2 wires from new mini harness too hood wiring for light , and to switch
