I found a quick easy solution for installing a tunnel cooler on my Riot 3. I happened to have the short C3 tunnel cooler used on Yeti 2016 kits when I sold that kit. It works out that the right "window" on the Riot 3 tunnel is the perfect size to install one of these into. Works great and keeps my big bore temps in check at all times. I originally found the cooler on ebay discounted used. I am also sending this thread link to C3 so they can hopefully make one specific for the Timbersleds. The only mod to the cooler I needed was to bend the front bracket up a little so it doesn't contact the track. I used simple 90 degree brackets off the shelf from a hardware store and stainless steel hardware for mounting. It is also positioned so you can still loosen the chain adjustment bolts without interference.
