Installing PERC Kit on 01 700 xcsp

[ramairtransam]

Guys, I'm a newbie here and just finished a perc kit on my 01 700 xcsp. I have some questions though. I used my original flywheel with the 3 degree advance key, I got a newer oil pump, the newer style temp sensor, and newer ignition switch (for premium option) off of eBay. I had to lengthen/re route the harness and added a wire for my reverse light. I bought the kit from eBay and it included the new harness, tach, clutch, etc. My sled appears sluggish under 6500 rpm and my top speed is around 80mph. Before it would run 115 over a frozen lake. The new harness has connectors for TPS and a Knock sensor. Is it possible the computer is screwed up because I don't have a knock sensor or TPS on my carbs? I've only ridden it once and I don't think the secondary is working right with my primary clutch either. Also, it's noticeably much louder when running in reverse than when running normal. I'm not sure if that means anything though. Any suggestions would be greatly appreciated

kit

I did not do anything with flywheel on mine. I did use the ecm the gave me along with sec. clutch. and I installed a starter pawl#5246108 off of a 2003. I did not change the oil pump . I have a 2002 and there is tps on mine.I did not see a knock sensor on block. I can not tell you how it runs out yet . I did break in only in drive way. It sounded bad a$$. I may take out today .

If you don't have a TPS wouldn't that retard your timing at high RPM?

TPS

That's what I'm not sure of. If nobody knows this answer I might just have to start looking for newer carbs that have TPS. Since it's not FI I don't know what else the TPS would do other than help control timing. Thanks all for your help.

harness/ running rpms

The harness you have is for a 2003 up? I was told that this was an option on newer sleds and this could be why there are extra plugs that seem to mean nothing. I took my 700 out to break in engine and it pulls fine past 8000 rpms. I did not have the room or the conditions to get it past 70mph. No dead spots at any rpm I ran.

DET sensor

not having a DET sensor on your motor when the cdi is set up for that will not effect the running conditions of the motor. the only adverse effect is the high temp light will flash slowly.

What CDI are you using? I assume you put the reverse CDI on it? If so the timing curve is dramatically different with it compared to your '01... that may be your performance issues right there.

If the CDI has a TPS plug on it and you don't have one installed then it switches the CDI over to the full timing curve. This is how you check the timing, unplug the TPS and then check the timing.

So what is likely happening is that you have the full throttle timing curve being used for a VES motor on a non-ves motor. What was the kit for? What sled? Was it for a 700 or an 800? Those both have different timing curves too. And if it was the actual accessory kit that Polaris made it shouldn't have a DET (knock) sensor plug on it because only the '03 Escape had a DET sensor, the other '03s didn't have the DET sensor and the '03 came with reverse.

PERC

Thanks again for your help. I bought the kit with harness off of ebay. It was listed for an 03 700 xcsp. After searching around on the net I determined that I would just need to add an advance key and I could keep my original flywheel. I had to modify the harness a little to make everything work. I got a new CDI box with the kit as well as secondary clutch, tach, handlebar switch, helix, and spring. While apart I threw in some Weisco pistons and rings. It starts, idles, and reverse works fine. Now the only other item I haven't mentioned is I put on a Snow Stuff rumble pack can on it. I'm starting to think the can could be causing my poor performance at low rpm. Especially since my engine doesn't have EVs. From idle up to around 6500 the engine burbles terrible and I'm only getting around 9mpg riding nice and easy to break it in. Next weekend I may put the original can back on and try it again. The rumble pack is louder than hell and appears to leak badly between the original pipe and can flange, basically a POS compared to the SLP I have on my Fusion 900.
