As the AMA Supermoto National rapidly approaches I have been spending quite a bit of time on the track for development & race simulations in preparation. Hours on oil are the same as my previous sample @ 4 (Mystik HEDO / see my previous posts), as well as the conditions which were 95% race simulation (high ambient air temps, race pace, high rpm, etc). This oil was worked hard, held up extremely well stayed in grade & had an outstanding flash point. This is their motorcycle specific formulated oil not a HEDO. Lead is high again, even though we have since changed to a fuel cut off for rev limitation vs. ignition. No fuel dilution, however I still believe this lead value is due to the nature of the race fuel. We will be putting in a new & modified higher output motor that should put us in the 70 @ the rear wheel range & I will sample this oil again under the same conditions w/ this new motor. Oh I almost forgot, silicone is 2x what it was before but when taking the sample I had failed to wipe down the frame rail next to the drain plug. Im confident it was the dirt from this mistake on my part & did note it to the lab when submitting the sample.
