Thread or video on setting timing

Hi I am looking for a good video or thread on how to set the timing on a 92 Polaris Sportsman 400.

My brother in laws ATV is overheating and I have tired everything else, so I would like to check/ set the timing and check/ adjust the valves. If anyone knows a good link please let me know

I have done timing on lots of cars and trucks, but never on an ATV, so help would be appreciated

Thanks in advance

I'm wondering what fellas are using for cargo boxes, front & rear, on bikes with the same racks as a 2013 800 Max XT. I'll also be looking for a set of new tires. More snow & bog, than hard pack. Probably 60/40%.
Great site & lots of info, thanks.
I'll try & post some pics from this past weekend. Any tips on posting?

Brand New XP 1000

I just ordered a 2018 Sportsman 1000. What are the highlights of this machine and what should I keep my eye on. I'm coming from a 2015 Sportsman 570 and i'm very excited. Should be picking it up Wednesday!

Used parts in North West Arkansas

HI,
Does anyone know of an ATV repair shop that would have parts bikes or salvage shop in the NWA (Rogers to Ft Smith) area? looking for parts for an 06 Sportsman 800 and 04 Sportsman 500.

Thanks
