2013 back shifting issues

snobyrd · Feb 28, 2013

I was just on another fourm and saw a post about poor back shifting , I'm havin the same problem, I have even installed a team tied secondary and I'm still having problems, to me now it's pointing at the primary, has anybody had roller or bushing problems that caused this problem?

mileage?

how many miles does the machine have?

snobyrd · Feb 28, 2013

just under a 1000, I've been fighting this for 400 miles, I just talked to a dealer and they said it could be a tps out of adjustment or moisture in it, I was thinkin primary clutch

My 13 with Carl's Clutching kit (springs, belly busters and helix) backshifts better than any sled that I have ever owned. You might call them about your issue.

I've had , tried thier settup on my stock clutch , no work, now I've got a tied in there and no work. I'm a lightweight guy and I should be able to pull rs all day.
I'm gonna get my tps looked at as well.

How do your motor mounts and clutch alignment look? My mounts were shot at 650 miles and had problems with holding consistent Rs. Also, if you haven't, try a new belt.

I'm sure you tried a new belt.
Mine looked good but I was loosing r's....New belt and I'm holding 8100.

snobyrd · Feb 28, 2013

I blew a belt at roughly 600 mile mark, when I installed carls kit, so there's a new belt in it now, btw it's a pol belt not aftermarket.

My 13 will hold 8300 to 8400 RPM in deep snow on a hard pull. It doesn't drop off. It clutches more cleanly than any seld I have ever had. It backshifts on descents just as you would like. It is ideal. Maybe I am just lucky. Who knows?

What elevation you riding at and what is your clutching set up

I just pm u tinker

Just got back from dealer, these were his notes
217 over temp fault
1477 exaust valve selenoid circuit open
1336 max det correction limit reached mag
1336 max det correction limit reached pto
2336 cyl mag knock level critical
Adjusted tps
Adjusted etc
Replaced spark plugs

Would any of this hav a effect on my back shifting issues

My 13 has dropped rpm at random from day one, its not bad but enough to notice, it will pull 8350 at the start then end up at like 81on a long fresh powder pull, maybe one out of 5 pulls it will be down to 78-79, but I can go right back up and it's back to 81. Couple real long pulls it was noticeable and I had to turn out, only notice this on a long wide open fresh powder pull, Was thinking of trying a team tied with teams helix and spring, called them and he thought that would definitely help and hold rpm better, he is trying to sell a clutch too tho. Idk anyone tried this and what were the results? Mine is stock with MDS weights and primary spring.

I need more information than that.
how many grams of weight with your MDS weights?
elevation?
track speed?

fastlane · Mar 4, 2013

65.3 grams 95-10000 ft didnt look at the track speed.

How are you defining "a backshift issue"? Not regaining RPM at all?? slowly?? When on/off the throttle or under steady throttle?? How much fluctuation? How are you determining it's clutching?

Winter, as I climb in untracked pow, the rs will hit 8400 than drop of to 79-8000, if I let of the throttle and stab it again it will recover somewat.
In a way I'm not totally convinced it's clutching, there were some codes that came up on the computer, and the tps and electronic throttle circuit were adjusted, so I'll have more info after next ride.

Fastlane, where is the weight at in your MDS weights? tip or base? assuming your running the drilled, allen head but where is it in the weight?

fastlane · Mar 5, 2013

One washer and the drilled Allen bolt in the tip. Correct me if I'm wrong but a perfect back shift would be hitting the bottom of the hill at 84 and at the top of the pull you are still at 8400. The clutch is constantly back shifting to maintain rpm just like downshifting a truck going up a hill etc.... Most pulls I don't back out of the gas and pin it again unless its a long chute and she needs a breather...
