Clutch help 1997 XLT

[Sask Sledder]

I have brought back to life an XLT that was sitting forxa long time. Carbs are clean. New pickup line. New needles and seats. Chokes adjusted. It runs like a top.

But im missing 1000 rpm. It only sustains 7100 rpm. I cleaned the clutches and everything is smooth and free, but i replaced the springs based on the recommendation from some kid at the local sled parts store who called his dad and asked him what springs i should use.

Its gotta be wrong.

Heres my setup:

White 125-280lb EPI primary spring.
10M/5 weights.
Silver/Blue Polaris secondary spring in slot #3

Ive adjusted belt height from 1 to 5 with little effect.

Where did i go wrong?

Maybe she's just bagged, what's your compression at?

 

[Sask Sledder]

110 110 95

Lets assume the engine is fine. Is this a messed up clutch setup?

 

[Sask Sledder]

K i returned it to stock clutching. Still only 7000. Maybe its just bagged.

Update. I checked compression instead of relying on my memory from spring.

Its Clutch 115-125-125 PTO

When I had my xlt I had similar problems. Any flat spots on the primary rollers or weights? I also changed the transfer buttons on the seconday.

 

[Sask Sledder]

New buttons. Rollers spin fine when i checked them. My next step when i get back home is to look for mouse nests in the pipes

stick a little magnet to the roller, there shouldn't be any movement, if there is the rollers are toast

 

[Sask Sledder]

Oh ok. They spin but there is play. Ill replace

Update: pipes are clear. I changed plugs but no difference.

On a track stand i get 8400. It goes straight to 7000, then seems to pause then goes to 8400. In the field it gets to 7000 right away at 3/4 throttle. If i hold it there it will creep to 7300. If i got to WOT it bogs down to 6900.

Primary is coming off again tomorrow now that i know what to look for.
