a NEW THREAD from question in the Riot gas can thread, request picture of how I mounted a heat exchanger on the Riot Kt.
The heat exchanger I used I had buit 4 or 5 years ago for my 2013 TS kit. I ordered snowmobile heat exchanger stock from WAHL BROS. Seems to be about $15 a foot. Then you find spigots and tig weld it up. Kinda lazy doing my riot, this one looked ok.
Picture shows it in the tunnel, has about 3/4" clearance, more that I remember on an old TS kit.
Included pictures to show how its plumbed on my 2013 KTM 500, used regular old Gates hose, silicone 90degree bends right off the bike, when I'm riding this is all covered with plastic.
So the Riot head exchanger is 12" by 8" about 96 sq inches of aluminum, mounted tigh up against the rear pan which acts then somewhat as a heat sink also.
I included a picture of a 3 1/2" by 11 1/4" or 39.3 sq inches heat exchanger that I ran two of these ( so 79 sq " with that set up }on the older TS tube frame kit. What I found was to keep 190 degree heat in my KTM 500, I could drop one of the these small heat exchanger and only run one of the 39,3 sq inch heat exchanges and no problem cooling even in spring hard trals if there is any snow kicking up.
My KTM runs so much better , just nice and clean and crisp at 190 degrees that running radiators just isn't an option.
Picture also of this setup with my Race Car plastic covers on last years setup and going back on for this year.
With heat exchangers, 190 thermostat, plastic covers/plastic skid pan, in cold 20 degree new 2 ft drop I had to cover the back of my engine and build plastic covers to defect the track from throwing snow up on to the back of the engine, breaking in trail 180 degrees really burning throughthe fuel, 190 when I would pull into Dan's track. Fact is I had to turn off my heated handle bars to get the temps that high.
So if you run radiators and a thermostat and don't run a heat gauge to know, you won't know how much performance
you give up or how hard it is on your motor when all you can get is 150 degrees out of the bike...........well that's my story.
