polaris atv clutch on a 420cc clone

[MMarty]

Hey there, If you don't mind me asking what did you use for rear bearing supports and half shafts? Also rear control arms. I am building a similar kart with a 420cc engine. I don't know if I'll use a polaris trans though. Thanks.

Wow that thing is awesome! Hope you get it tuned the way you need! Wish I could help!

 

[MMarty]

Thanks, I don't have the new engine on it yet. I'm trying to get all my parts choices lined out first.

I used a Polaris magnum front drive as my rear IRS unit and scratch built the arms and hubs, it works pretty well so far

 

[MMarty]

Hey thanks. That is a great setup you have. I'm gonna dive into it this fall and start my fab work. I have to keep an eye out for some parts.

thought I would post a couple of updates, I ended up changing my front spindles to run a hydraulic brake, got rid of the hand controls and switched to a standard steering wheel, added a 32mm Mikuni CV carb, and changed the frame some.

Its been running well and fun to drive.

[Arkyhunter]

Man how did you get the driver clutch off the polaris. I remved the bolt but it want move.Is there something else to do.

Thanks

They make a tool for it but if you search for homeade polaris clutch puller you will see how you can make one froma bolt and a punch.

I got my adapter and the paper work said to cut and rethread the crank shaft.Man that sounds spooky to me.How hard was it to tap the crank .Was it standard or mm threads.Sorry for all the question but dont want to mess up my motor.My trannys off a 250cc so I hope I dont have to mess with the springs.

Thanks

I can't remember for sure but I think the clone shaft is a 10mm stock.
I drilled it deeper and taped it for the 3/8 polaris clutch bolt (before I cut it), I believe you could use a 10mm bolt if you get a bushing that will work with the clutch.

I needed to cut the shaft only for fitment in my buggy, if you have room you should not need to cut much at all from your shaft using the spacer and adapter only leaves about 1/4" that needs to go.

changing the primary clutch weights and spring is very easy and you may not need to depending on your gearing and weight.

the secondary is a little harder but not bad

its a good idea to clean up used clutches and inspect them for worn or broken parts before deciding that the motor or gearing is to blame (dont ask me how I know)

 

[Arkyhunter]

Did you have to use the tranny brake on your buggy to get it to shift.
Thanks

[poordad]

yes you will need to use the brake to stop it so you can shift and I use mine as a rear/emergency brake

 

[Arkyhunter]

Well thats slick thinking their. Thanks you for the help if I can get a couple of days off with out rain I could get my buggy going.

thanks
