hey firko, cant remember the thread you mentioned him in but you talked about JIm P, i have been going through some old US cyclewords building up info for my log book/eligibility stuff and you should see some of the crazy stuff in these mags, most pre 74 even a Duc like yours as a SSS, anyhow back to the point here is one of your mate Jim selling a line of hat's.
p.p.s note also re airhearts, as i agree, you were correct in letting that bike though at nats, they are legal here is proof see rear disk on the champion FT.
ill try and pull out some more of this stuff you should see the chooper pipes, some good A/F stuff too, funny you never notice this stuff till your looking for it, there is even a factory Yamah skyway PIpe for the MX 250 that they claim reads 85 db.
