Where do I start?

Here's the sled.
It's a 90ish exciter with a piped engine. I long tracked this baby to 144 (only one I know of) and raised the back end. swaped in 7 tooth drivers to clear the cleats and lightened it up a little. I'm about a 170 lb rider.

Anyway, now that the seven tooth drivers have lowered the gearing I'm not getting any backshift out of the secondary. Engagement is around 3200-3500 (shouldn't it be higher?), from there it pulls pretty good till about 25 mph and tops out of RPM's (I let off so it won't blow up on me). When attempting to climb hills, I actually get farther up the hill on about 1/3 throttle than floored. Also, when I climb hills my track hardly slips at all, I can't get the track speed up enough to spit any snow.

I'm not sure what the weights or spring are in this clutch. I'll have to check and get that on here.

So where do I sart? Should it be the primary to the secondary? Should I look at heavier weights? Maybe a stiffer spring? I know I could adjust the tension on the secondary to get better backshift but I've read that the primary should be the first adjustment you make.

Any advice would be greatly appreciated.

Sorry; exciters are out of my leauge. Never ever messed with em & don,t have a clue....sorry!
 
gearing still too high?,going to 7 tooth sprokets plus having to turn that longer track might be too much for your gearing?

Pat i think it would bog if that was the case 7 tooth are pretty small and bottom gear should be changed to compenstate.I have gears for this sled if you have any problems finding any.I would go this route trying to load the moter with gearing, than fine tune clutches for proper revs.Exciters need a good moter link to hold them down with high engagment or the front moter mounts will crack around the washers.
 
Good deal. I think a gear might be in order for it.

Here are some pics of the sled in question.

Here's what I think, and lend me your oppinions.

The engine is definitley not having a hard time turning the track. It's hardly loading the engine at all. I don't know what was done to the clutch before I got the sled. I know something's been done since the clutch on it is an arctic cat commet clutches.
I've read that for every tooth you go down on drivers you lose roughly 15 mph, that should net me a top end of around 66ish mph. I'm not getting anywhere near that. This leads me to beleive that since the engine isn't under as much load as it was the clutches aren't shifting properly and (actually now that I think about it the sled didn't shift out like it should have back before I did the track swap on it so something's wacked in the primary). The secondary clutch hasn't been touched.
Since it's a mountain sled I don't want it to have any more than a 60ish mph top end so I would like to avoid regearing it. I will if I have to though.

lend me your oppinions and info.

bluewho your right got my stuff backwards, smaller drivers= lower gearing. sorry about the mix up.

What would give me a higher engagement? A stiffer spring?

I have an exciter with a almost brand new commet clutch on it. I'm going to transfer the weights and spring over to see what kind of change it makes in this sled but if I remember right the engagement on that one was low too...like around 3500 or so.
 
What altitude are you at?
We ride at 4000 to 6000.
Gearing in the 2.20 area with 8 tooth.
Yamaha Comet or Comet clutch = square yellow spring and A-1 mod weights.

Exciter SX is 136X11/2 track.
Can't hardly stop it.
 
Snomoguy, I'm ride roughly around 8000, I have an arctic cat comet clutch on there now with a-1 weights and a yellow/green primary in it right now. I have another thread that's going over this a little and goes over my latest changes. I'll have to find it and post the link.
