Wobbly 2 moto sprocket

[teal_210]

After a long ride I noticed that the sprocket behind the brake rotor (the one driven by the bike) on my 2 moto kit has some side to side play in it. Is that normal? I don't recall if it was tight when I first put the chain on.

If anyone has some input, I'd appreciate it. Hopefully this is a normal thing, I'm not looking forward to taking that hub apart.

Thanks

I'll look

Hey man, I'll take a look at mine tomorrow and let you know.

went riding today... good snow and tons of tight trees. little lawn dart action for good measure. hahaha my partner had to take pix before he helped me dig for the front end! probably show up here sooner or later.

Perfectly normal!! I never really asked why but makes sense to me that a little side movement will allow the sprocket to line up with the other if the dimensions are a little off. Every kit I have installed has the same amount of movement in the hub sprocket, so should not be anything to worry about.

Thanks Crawfish, I was hoping that was the case.

Dropped into a big bowl last time out that the sleds couldn't get to and ran out of gas. Got me thinking just how bad a mechanical failure on one of these could be. We would have had to carry it out with man power or leave it there.

I don't see why you could'nt tow from the forks as we do the Hawk's, for us once you remove the drive belt it's quite easy.

lots of torque

so guess i didn't have to check after all. good to go.

as for towing on the fork... not my favorite idea. if you do it down low that would be a lot of torque on the fork and the triple clamps. maybe up higher but (depending on the angle) may cause difficult steering or too much down pressure. I talked to a guys that suggested using a strap with hoops at each end (like a motox tow strap) and putting them over the foot pegs. the middle part of the strap would be out front of the bike near the ski hoop. in his version, a second line would attache there and then hook to a sled for towing...

this brings up a good question. anyone have any "real world" experience with it? thought i was going to yesterday but got it sorted out. ADDICT, the bike can be shifted to neutral so no "belt" removal needed... if a guy was worried about bumping into gear, he can break one of the chains easy enough.

We towed a toasted 450F out about 15 miles last year,It was all groomed trail, Used a sled for the tow vehicle and tied of at the triples just like you would with tires on the bike.. held the speeds under 35 no issues and really a piece of cake..

thx. good know its easy... hope i don't have to find out the hard way. haha

I'm sure it's possible, my concern is how do you get it out of a bowl where it takes a 300 yard sidehill to get into and out of? None of my sled buddies would drop in, and the bike could barely get out under it's own power. Not a chance a bike could pull another bike out of there.

Yeah if your going to tow a bike it pretty much has to be on groomed trail or hard pack. We broke a chain on my buddies CRF a couple weeks ago, luckily he was only about 50 yards from the trail when it happened. Just took a tie down and hooked it to the grad handle on the back of my track, hooked the other end to his handlebars between his bar clamps. It worked just fine, the longer the strap the better, two tie downs hooked together would have been ideal. At first we tried to hook to the front of the ski... hahaha that didn't work so well, I do not recommend trying it! But yeah you can tow the bikes, just put it in neutral.

This is just one of those situations where I think snowshoes would be a wise item to pack on my back. (Along with everything else I carry on my back)
