In October I received an email from Jim Mosher stating that he just got back from Bonneville and that he had prepared a Commando of only 873cc that tied the 1000cc altered fuel pushrod class record of 155.722mph.
Jim said that he pulled out all the stops but only raised the compression to 10.7 to 1.
As far as I know, this is the absolute top speed ever attained by a Commando, certified.
I can tell you that Mosher was pissed to only exactly tie the record. He said he will be back next year to claim that class record.
Jim Mosher is recognized as one the very top vintage engine builders. He is currently building a double engined Indian for an assault on the top speed record for that class.
I am very lucky that he lives only 70 miles from me. He completely rebuilt my own 850 this past May and June. It is one strong street motor.
