On the Sq4 magdyno the flat side of the distributor must face to the left of the machine, n'est-ce pas?

Re: Motorcycle Magazines - What to do with them ??

Hello Bob,
Why don't you ask friends who drop by if they want them? I have several buddies with whom I exchange bike magazines. Anybody can stuff a few copies under a motorcycle jacket.

Out of curiosity, how do you plan to overcome the spoke holes problem?

Hi Kevin,
I think you should join the AOMCC and then you would have access to a lot of helpful information. The following was published in the November, 2010 Cheval de Fer (the club magazine).
