Hi,
Today's project was to service the blue '84's TCI connections and in the process, to relocate the TCI unit onto the top of the air box, as per accepted VR.org practice and advice.
(I was motivated to do this as my heat sensitive, intermittent, 3k rpm and up misfire under load has become intolerable lately. Cold mornings she'd be miserable / hot afternoons she'd work fine but lately she has been increasingly unhappy even in the afternoons unless its extremely hot. Seemed obvious to me that it was some thermal expansion at a connection somewhere. Likely at the TCI.)
Ok so, after a long struggle, I got the TCI free of the bike. In triumph, I sat down with it and a spare unit, bought on ebay a year or so ago, to compare the numbers on the two units. All numbers printed on the silver label match exactly. However the numbers embossed by numbered punches differ by 1.
My original has 310 punched on its label and the spare unit has 311 punched onto it.
Originally I assumed that the punched numbers were a serial number but ,considering the numbers of these bikes manufactured, it cannot be that I have s/n's 310 and 311. (If that turns out to be the case I'm off to buy a lottery ticket!)
Can anyone tell me what these punched numbers represent and if its significant, should I ever need to swap the ebay unit in as a replacement on either of my '84's?
Thanks,
Brian H.
