I am so fricken irritated. I bought this sled two weeks ago (2,900 Miles). I went through the carbs and checked the compression. Two pilot jets were a little gunked up, but everything else was in great shape. The compression read 135psi +/- 1-2psi. I took it out in a short field and it was hooking up well, but not getting nearly the RPMs (around 7,000). I then proceeded to go through the power valves. They were dirty, and a cable had pulled through one. The other two were in great shape, so I cleaned them up, put them back in and replaced the bad one with a new one. I adjusted the PVs with the idle below 900 and 2.5mm allens for spacers method. I took the sled out on the lake (3 in' of two day old snow) lastnight to test it out. I was not hooking up that well, but I had a nice little straight track. From a slow crawl...if I pegged the throttle...the sled would nail 8,000 RMPs real quick and drop down to 7,500 almost imediatly. Anything over 85 mph took some time. I took the sled to some snow covered turf and hooked up real well...the skis pull off the ground, and it pulls really hard for a few seconds, then it is kinda flat and (7,500 RPMS) again. The sled has a bender can and a bender clutch kit...helix/overide. The rest is bone stock. It was dialed int for the former owner (190lbs) and I am 240 lbs. Does this sound like a clutch issue? What next?

The plugs were new this year (two weeks) and looked good before I took it out. I just pulled them and they still look good. I will put a new set in and make sure the PV's are all still hooked up. Be back in 45min-an hour.

Well, none of the power valves had pulled through. I ran new plugs (BR9ES's). I didn't run the sled that long...may be 5 mins to get to the feild 15 mins in the field 5 mins back. When I was in the field I was opening it up for 6-10 secs at a time before I had to let off. The base of the electrode just above the last threads looked a little light in color...the other two looked fine. The sled hit 8,000 right away and settles around 7,500 2-3 secs latter!!!! RRRRRRRR must right this weekend!!!
It would probably be a good idea to check all your clutching just so make sure on what you have. Post on here what you have for primary weights and spring. Whats your engagement? Is your gearing correct also? Once you have this info people can start helping you rule things out. It sure sounds like a clutch issue. Turk or Mr.Viper are very knowledgable and helpful when it comes to clutching issues.
Aren't you supose to be using BR9ECS plugs ????? Just an observation.jsutton83 said:Well, none of the power valves had pulled through. I ran new plugs (BR9ES's).

your back shifting....what we need is your clutch set up, primary and seconday and let us know. there's a tryed and true set up for the srx you can try we just need to know your set up,make sure P/V are good and adjusted.
always premium fuel and BR9ECS plugs..

Check your pv adjustment again they have to be exact! There is a harness I bought that works great it works on SRX'S and vipers.

I'm with the others, sounds like a clutch issue(as long as your sure you adjusted PV's correctly). Like they said, see what's in the clutches and report back. Primary spring, what arms, what weight rivets in arm holes, secodary spring, helix angle, what wrap it was set at. Since you have Bender stuff in there, the springs and helix probably won't say what they are...someone on here can probably help you there though. Also might need to weigh the arms to help identify what weight rivets are in them...
If he put a clutch kit in it, there's no telling what's actually in it. Most important at this point is 1) What flyweight is it. Yamaha #'s are on the weight, a picture would help. 2) Primary spring and engagement shims if any. 3) Roller diameter if you want to check it now while you're in there. 4) Secondary spring and setting(which holes is each end in) 5) Helix number, picture would help here.(Yamaha helix numbers can be dechipered in the tech pages)

Too much tip weight will pull your top rpm down.Is it shifting out to quick,maybe tighten your secondary and see if that helps.Check all your clutch springs,bushings,rollers,drive belt.You have to take the clutches apart to check the inner bushings.It does sounds like a clutching problem.I pull mine apart every year and blow everything out with the compressor and check the items i listed above.I also replace my primary spring every other year because they get sacked out over time.You'll figure it out.

k i have never been into clutches before and i know the previous owner had some clutching done how can i identify what i have
