I [Deon B] agree with Lefox that it is of UTMOST importance to get the oil ASAP on operating temperature and that a TO LARGE oil cooler can actually have more damage on the engine that running hot. I have changed to new synthetic oil Castrol Edge 10W60 and the bike is running better. I have wrapped the headers, have the insert below the seat [new insert only for the SS and Ulysses models] and found the whole concept to be much cooler, but my bike still runs hot, the fan continue running even traveling on the highway [160km/h], I am concerned that the fan will not last and have at some stage to replace it, and believe me in the RSA you are talking of ZAR 3500+, a rip-off, but that is what the Harley shops charge, do anyone know of any ‘generic’ parts???
