It might be a case of "some" are loose and "some" are tight. This was the case of the earlier Quickdrive gears ont the Polaris driveshafts. The loose gears were breaking retainer bolts as they wobbled under the head of the bolts until the stress was too much. You don't hear about that problem much these days. I have a buddy with a G5 and he did not get the grinding sound like some have reported. Hopefully that means his is good as I am not excited about the thought of towing that big sled off the mountain.
And there you have it, ride it like you stole it. Maxwell said it is good, so it is good.
There is a thread on Snowest forum about upgrading the drivers. I am not sure if it is needed or if the tracks are stretching more with the extra power. 6 tooth drivers have much less grip on the track than 7 tooth.
Ya im def running the track a little tighter then the g4, it has happened with and without the iceage big wheel kit was hoping i could run the track a little looser with the big wheels but nope
Possible that the longer suspension arms are collapsing in on a big hit and because they are longer they let the track get looser when they fully compress?
Redline includes 7 tooth drivers with their turbo kit. Says the 6 ratchet too easily under increased power.
Dont even want to say what Max said about ya but we rode today and gears held together
Lots of chatter on snowest about chains wobbling and slapping
