i just installed a heater on mine. Haven't had time to ride it long enough to see if I burped it correctly but upper and lower hoses get warm in correct order so fingers crossed. I went several months ago to Buckhorn in NW Arkansas and it is amazing how well it climbed and performed. Only fatality was rear brake rotor which was damaged due to locked brake caliper, nothing the ride did just old age (11,300+ ) miles.
