500 Cam Stuff

I've been meaning to post some of the info I've found about the cams and pistons that came with my '51. I'm primarily posting this stuff so I know where to find it later but some of the history is just kinda cool too.



It came with a stock set of cams (E1485's). According to a couple of Triumph books I have these were only used on T100's both intake/exhaust for one year (1939). They continued to use them for exhaust alone 1946-49. My bike would have originally had the E2302's that were fitted 1950-52.



It also came with a set of JOMO TT cams. I tried to get a photo without much success. They are kinda neat, hand engraved "JOMO TT." I believe they were custom ground by Johnson Motors (or ground later as replicas of the JOMO's). The TT's supposedly had a little more duration that the Triumph factory "Q" cams supplied in the '50s 500 Race Kit and later pre-installed in the 650 TT specials. The claim was they provided a little more top end power. Pistons next.
