I haven't run regular pump gas in the bike. the "pump" map I have is for renegade fuels p95 (95 motor octane). it is a non ethanol, non oxygenated, unleaded fuel. I buy it locally from a distributor. I ran that all last season on my 05 636, and the end of the season in the 13 636. it is a great stable fuel, safe for fuel systems and long term storage.
when we put the .050 mm head gasket from kaw in it (not the thinnest made), it took the compression from 12.35:1 to a solid 14:1.
the mr 12 fuel is only 87 motor octane but, "pump rated" for 93 octane.
my motor and tuner guy was not sold that it would be safe for long term use in my motor and wanted a octane cushion. so, that is why we stayed with the renegade, and then tested the vp u4.4, which has a higher octane rating as well (108 "pump rated, if I remember correctly).
