Silber turbo no bottom end

[bk720]

Hey guys anyone have a cure for silber turbo with bully dog bottom end lack of jam and turbo lag? Mine is tough to ride in the trees from a dead stop or quik throttle application. Power is slow to come on. I also wonder if I'm pulling
7800 Rpm at wot, how much weight do I need to remove to get were I need to be.

Cheers

At least a couple grams. You can make it more revy with a different primary set up. Mine is very responsive, I have the pink just what Justin sent with the kit. I know a few guys who installed a lowe engaging spring and lost the throttle response.

bottom end

you might want to look into the mds turbo weights, I am running them with a pink spring, my engagement is a little higher than I would like but bottom end response is good

Thanks guys. I do have the pink spring just not happy with dead spot. Maybe less boost so I can run lighter weights in my primary?? Maybe that would help. Rite now I'm running 8 psi at around 3000 to 6000 feet in elevation

Take your primary clutch apart and inspect all the bushings and rollers. Also put a new 115 Polaris belt on it.

What will the belt do ? And rollers and all are good. Had it apart not long ago . Has a big at first but soon as rpms are increased and sleds moving it rips ??

New belts make a huge change if the belt is worn.

Yea I agree but I got only a few hundred miles on a new belt. Doubtful that is the issue.

i agree. sounds like clutching from the first post was it running different 3 rides ago

If the belt sits to far down in the secondary clutch it will do the same as having higher gearing. Check your belt deflection and adjust as neccessay. Also make sure the primary spring isn't broken.

And at the very least take some scotch brite to the sides of your belt.
