Sounds like that sportster's got your number D&H - givin ya grief.

We stay away from the ehtenol too - v power 93 in the 'King, and for the Springer, we get 100 octane from the airport. They can't put it in the bike, but will fill your cans. Some say money wasted - don't know for sure if there is a big difference in mileage with the 93, but it definatly runs better. The Springer (10.5-1) will run on the 93 - but way better with the av gas.
Figure that mouse got them soybeans down in the cases with one piston at BDC (all ports open - 2 cycle engine). Must have been an ambitious little #@!@!
Good that you got in some riding yesterday.
