Fan-Assisted UltraCools for M-8 and earlier

Harley would have everyone believe that with the M- 8 it has addressed the notorious heat issues that have plagued its 45-degree V-twins since , well , forever . However , the reality is that while the M-8 is marginally better than the Twin Cam , which in turn was modestly better than the Evo , the fact remains that even after relatively modest rides you could fry eggs on those heads ! Enter into the search for cooling solutions the UltraCool range of fan-assisted cooling systems for Harleys , including M-8 models . Sold by PC Racing , owner John ' JJ ' Petchel says : " Harley ' s so-called ' liquid-cooled ' engines only water- cool the exhaust ports on the engine . The stock cooling system simply is not enough to keep the larger M-8s from overheating in traffic and city riding .
