Newest product-ATV track system

Just some friendly advice on new tires. Check with your ATV dealer. 
There are so many aftermarket sites, Revco, Royal Distributing, Partzilla, and on and on. Even with their “ big sales”, my local Canam dealer’s REGULAR price beat the tire prices of the 3rd party sellers! People often assume the Dealership will cost them more, but I found this not to be true!

I have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here.  I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc.  IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up.  Happily, it runs and changes gears well in L,  but it will not shift into H or R for anything.  I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?

I took this video back in 2007. Recently the trail (old railroad grade) I was riding was converted into a walking trail (obviously no more ATV riding on it) 👎 I dug up this old video and put it together since it shows the entire section and what it used to look like. The quality of the video is lacking, but this was from 18 years ago. Image stabilization didn't exist back then so I wore the camera on my helmet. (mounted to the quad was useless with all the shaking) so there is some annoying frames of me looking around. I noted any historical items from the railroad in the video. There is a section where the railroad grade is wiped out due to erosion so I had to jump off it and ride an abandoned road for a section to get around it. 
 

Can you put tracks on manual atvs? would it be effective? is 280cc enough to even move them? thoughts/suggestions?

SO is this website mainly for help with atvs and stuff?
