Clutching

[87gtNOS]

With in 1/10 gal on fill up.

I don't think he meant fuel mileage!!

Did a little testing . Put my stock clutching back on my attaks.. Milage about same. One pull 500 more rpm than the other. Switch clutches same sled 500 higher rpm.. Can one motor be that much stronger than the other?

Yes, most defintly one could be stronger the other? How many miles on both.

22 different Sorry. DUH old age taking over.

Also, if you look at all of the dyno's so far on this motor, I'm not sure how spinning a clutch kit @11000RPM is good for the motor for trail riding and, also, you are out of the powerband by atleast 5hp. How can that be good for getting all the motor hp to the ground? Yes, I know about the torque or these 4 strokes, but it just does not seem right. I could maybe see 10,600-10700, but not 11000.

Sled Dog,
Looks like you have a mountain sled, and I believe they came with the bigger rollers in the stock clutch (please let us know...). If you run a smaller roller, it will lower your engagement (It will also squeeze your belt better…). But, it will also raise your top end RPM a little maybe 100/200rpm). In order to fix that you either have to run more tip weight (I suggest this), or pull back on the helix angle (51/43 to 51/47 for example) with no changes to the primary weights...

I think your out of the ball park. Just my opinion,but first he has to tell us what it does in the trail that he doesn't like so that can be changed without changing what he likes when he's hill climbing.

Sled Dog, I have a problem similiar to yours. On reengagement of clutch after backing off throttle. It seems rather abrupt. Not sure I'm describing it correctly but, reengagement seems abrupt. Maybe it's the great performing engine. I didn't notice it on my warrior but do on Attak. Any ideas? Also, once you hit rpm on backoff where clutch is no longer engaged your free wheeling.

Byoffcr,

Have you tried switching belts between the sleds.

Maybe one is a little more glazed or perhaps greased.

Allen posted about the excess grease on the secondary shaft with a number of the sleds he worked on. Checked mine, it was over greased.

When climbing with my stock 04 Rx-1 moutain I was revving 10200 to 10400 with a track speed of 80 something kph it didnt climb that bad actually and it runs good enough for what I do in the steep and deep. When going really slow trail riding I find the clutch engagement to high. What I mean by this is where I ride in the Ducks there are some real tight turns and the trail narrows where you have to go really slow. I find I have to kick it in then back off kick it in & then back off but only when I have to go really slow. As for top end on the trails and lakes I have enough top end for me there already. I am 250 lbs so basically I would like to lower the engagement to make it more trail riding freindly and hopefully keep its hill climbing abiltiy that it has now. Hope that explains it well enough

no but they are both washed and clean.

I don't have alot of experence with the rx-1 but it sounds like the same problem with the apex. The engine goes to an idel very quickly, the clutch disengages and the thing wants to stop then you give it the gas and the thing leaps. (very annoying) Take it for what it's worth, if you raise your idel up to at least 1800-1900 rpms it doesn't kick out as fast and rolls through thoes little corners easier.

I don't think a clutch kit will solve that problem. If it does it will probably suck every wear else

I will definitly try that sounds reasonable enough to me that it should work and I can put up with a higher idiling engine. How does it shut off with the idle so high though does it backfire and stuff?
