Recoil Starter 2007-2013 TRX420

I know about the recoil starters for these 2007-2013 TRX420s being useless if the battery is completely dead. The idea is still interesting to me for a weak battery (IE: left the lights on too long) or something like the starter dying.

For $150 it’s not quite worth it right now, but I’ve seen a few of these kits pop up for Canadian TRX420 pre-2012 at close to $100 less. Even adding in the shipping it’s close to half the price. Is there a reason that the canadian kit won’t work on a US spec TRX420?

FWIW my Rancher is a 2010 TRX420 FM.
