I noticed that there seems to be a little slack in my throttle cable at the throttle block that wasn't there before. We always check full throttle in the race cars, no sense in paying for the HP is you never use it. So the easy way to do this is have someone push down on the pedal until it stops then turn the shaft that the butterflies connect to and see if it moves. So on the Pro, I see the round bell crank that sits right behind the brake disc that appears to be connected to the butterflies in the throttle bodies. When the flipper is against the bar I can turn that crank a little bit,maybe 1/4". It feels like you are pushing against another spring that last little bit. I don't want to be stressing the throttle cable for nothing. Running the cable too tight can wear out the bushings in the throttle bodies and break the cable over time. Any advice? BTW, the sled runs strong. I pull 8150-8250 at the elevation my clutch is set up for.
Am I getting full throttle on my Pro?

I know that on my 2012 pro 800, my throttle cable stretched like crazy. I mean, almost .250" slack from new to 150 miles. So all I did was adjust it until my throttle just came into contact with the block. No slack and no pre-load, just neutral. My machine just feels more snappy in the lower end after adjusting and getting that slack out. Might be factual, might just be me, but it sure feels better.
Did you adjust it at the "wheel" I was talking about? Looks like mine has stretched about the same as yours.

I adjusted right below the throttle block, in front of the bars. Under that rubber cover is the adjustment for throttle cable freeplay. I've heard it calls for .010" freeplay on the tight end, but I just carefully set it at zero, neutral. I'm sure it will stretch a little bit more.
Thanks. Do you measure the free play at the flipper? Right now I have a little more than a 1/4" between the flipper and the throttle block at rest.

I don't have a service manual to go by, so run this by someone else also. But I had about the same static freeplay as you do. So I adjusted the cable to bring the throttle lever to "just" touching the block. I didn't want freeplay and I didn't want preload.
I adjusted slowly and watched the throttle lever. When it touched, I stopped and locked it down.

Exactly what I did. The cables do stretch and 1/4" is way too much slack! Make SURE you check the idle of the sled with the skis up, turning all the way to each side, to be certain the motor doesn't come off idle after you've made the adjustment. The service manual states 0.010-0.030" for the spec.
Have FUN!

I usually adjust the freeplay so that you can just fit the skinny part of a zip tie in there. Normal for the cable to stretch alot the first while.

Check your cable!
Looked at mine tonight and guess what...like a quarter inch of play, Been driving all year like this! Wasn't experiencing any abnormal problems. So even if it's running good check that cable stretch because it could be better... Will have to wait for a couple weeks when in cooke to run it again
