Meant to post this as a new post no edit my last..not sur how I dis that..on my phone.
Just curious what are you seeing for engagement and shiftout out of the box
Highoctane what is you factory rpms?? Stall and then shiftout??
Heres the thing..new it would engage at about 1550-1600...now it engages at at about 1450 (if you ease into the throttle you feel it start grabbing), right off idle it starts grabbing.. The primary spring has weakened. Real nicey nice engagment..but not good for performance...and not only does the weakened spring affect engagement it affects shift rate..Shiftout RPM is good..it is about 8100-8200..problem is it doesn't hit shiftout RPM until about 50 mph now..I wish I would have paid more attention when it hit shiftout new..it think it got to 8000 faster..I know there is a min. ratio..but I cant imagine it is so tall that it can't hit 8100 until 50 mph?
I can tell performance has fell off a good bit recently and the lower engagement RPM tells me the primary spring going away is responsible...
Anyone out there with a low mile XP 900 can tell me it you nail it from a stop how fast you are going before you get to say 8000 RPM?
Lazypitbull what about with the DD set up? speed before it hits 8000?

I will let you know, going to a race this weekend in Georgia so I will get a lot of time in it, I think it is around 55 when it hits 8 grand, but the speedo is so slow, ill check with gps

I'm basing mine off the speedo..that sounds even slower to hit shiftout. I should have mine tomorrow and I'll compare on the same machine.

I got my DDP clutch kit today. Very nice little package. Love the adjustable weights, should be a little easier to work with than some others I've used when it comes time to make adjustments..no tiny screws to drop and loose, no o-rings.




I got the kit installed but couldn't really do much for testing today..just some easing and some pulls to maybe 40 mph...maybe 5 minutes worth.
Engagement is about 1850-1900, I like it, hopefully it won't fall much as the springs break in. The higher engagement just helps the engine be in a postion to make more power before it is loaded..at 1400-1500 stock engagment..the engine isn't making squat for power / torque. With an 1800-1900 engagement in low you are over 3000 by the time you get to moving good and this thing feels like I would creep up a wall without straining.
I'm thinking it's going to hit shift out quicker than it did stock..I was hitting 7800 RPMs by about 40 on the speedo..but I'll need to take it out for a full run to know far sure.
The high speed engine braking is MUCH better, doesn't feel like you are riding the brakes with your left foot every time you let out like it does stock..low speed there is still engine braking,but it isn't harsh... i need riding time on the trail to fully explore the engine braking.

I'll give more feed back once I am able to ride for more than 5 minutes lol..so far I like what I'm liking what I am seeing.

any updates ?
Overall I'm happy with it..I did lose a few MPH on the top speed but I never run that fast anyway unless I am testing 75 is plenty fast for me..
After adjusting the weights I've got it coming out of the hole much better than it did stock....0-60 in about 7.3 average..stock it takes 8+.. the helix makes the engine braking much more user friendly.

I did quite a bit of experimenting adding and subtracting weight in different places( heel mid and tip) just to see the effect I ended up going back to the set up Dale sent except I dropped a little weight at the heel to eliminate a little bog that I was getting out of the hole.. It wasn't a bad bog, it came out of the hole better than stock but I knew it could come out even harder..
With that said every thing is a trade off..by dropping that weight I probably get a little more low speed slip when loaded but if I do it hasnt been noticeable or caused any issues so far. I wanted the quick take off..and I went from barely getting any spin on pavement when it had stock clutching to consistently leaving 15ft black marks now..it launches a lot better. I have the exact change written down at home but I dropped about 1 gram from each heel iirc.

Have you noticed a change with rpm engagement like with the stock clutching?
Yes, a little..and more so how fast it hit shift out..engagement dropped a tad after fully compressing the springs several times..that's normal IMO..the springs settled in pretty quickly and I think Dale compensated for that.. and hasnt changed again so far. Another reason I am a big fan of adjustable weights. I put several long wot runs on the springs before ever messing with anything.

HIGHOCTANE, Do you still like your Dirty Dog Dale clutch on your XP? Just wondering how it has settled in for you.
I'm still 100% satisfied. I recently changed wheels and went to heavier aftermarket axles..very nice to be able to make adjustments for changes like that.

I finally got around to installing my DDP clutch today. I put it all back together and went for a spin. I was a little surprised when I went to stop the clutch would not disengage. I was glad I had plenty of room to stop as the brake needed to be pressed pretty hard to stop the buggy and stall the engine.

After taking it all back apart I found the culprit. My flyweights came from DDP already weighted. So, I put everything in like I got them. In doing so I did not notice the amount of weight the heel had installed actually made it too wide to fit up into the flyweight cam/spider correctly. Because of this, the moveable sheave could not release all the way back to it's neutral position when the clutch disengaged and the belt tension remained. I only realized this because the weight retainer bolt had gouged the cam/spider area pretty good when the clutch was trying to get back to neutral. The flyweights came with 3 large weights installed on the heel. This put the retainer bolt sticking out 6-7 mm, obviously to wide to fit into the cam/spider area correctly, and not allowing things to go back to neutral position.

So I took one of the washer weights off the heel, this brought the retainer bolt in 2-3 mm. This was enough to allow everything to come back to it's neutral position. Put everything back together and took it for a spin. Everything worked great.

My question is for those who have installed this clutch, what weights came installed on your heel? Mine had 3 of the wide washers and a bolt that has a much thicker head than the other weight retainer bolts in the middle and tip. If Dale is sending all these out with weights like mine, how am I the only one to have issues?
