Yes, I had the chance to go pro, but I never did. I was "AMA Qualified" (you need a certain number of top 3 finishes), but at the time people like Kenny Roberts, Randy Mamola, Chuck Askland, Gene Romero, Mike Baldwin, etc. were the hot guys on TZ750's (Yamaha's GP bike at the time, 4 cyclinder 2-strokes.)
My little KZ650 superbike was not really competitive (friends on similar bikes would get lapped 2-3 times), so I figured why bother? I just plain didn't have the sponsorship & $$$. Roberts was busy badmouthing "Streetbikers getting in my way" to everyone that would listen anyway.
I wanted to ride against Roberts (just so I could "get in his way"), but figured I'd have absolutely no chance at a win, or even a top ten so aw the hell with it. Friends on similar Superbikes would finish 15th-20th at Laguna/Sears Nationals at the time & I just didn't want to run if there was no chance at winning.
On the other hand, I was finishing top 3 in the AFM consistently, w/a couple occasional wins, but mostly 2nd/3rd place finishes. So why run for top 20 when I can be top three? Much cheaper too. I had a few sponsors, but the big bux was reserved for the "little guys." You see, I was 6'3" & 235lbs. when I was in top shape (football player size), & all the little guys had HP on me simply cuz they were 100lbs. lighter.
One of my local sponsors flew me to a LA dealer (only) show once to shop for sponsors, & had folks like Ken Clark (Yamaha Racing Mgr., Sparky Edmondson, etc.) tell me I was "too big to be a bike racer." So I didn't gain any sponsorshop there sadly. I had to suffice w/Richmond KAW, Dunlop, Wheel Works. Lockhart, & a few others. Mostly discount bike parts; but my partner at Richmond KAW was Rich Oliver who was a GREAT fellow team member! We all know Rich's history of his later years in racing...
No regrets, I got 8 full seasons of hard racing, & I had a ball. I stayed involved w/AFM/AMA for a few years more after my 84' retirement wrenching for others. Best placing as a wrench (Jeff Banister riding) was a 2nd place in "Open Grand Prix" in the 1987' Season Championship running a GS1000/former John Woo superbike.
It was the most fun & exciting time of my life so far w/the exception of my children's births, & a time I'll never forget. If only everyone could be so lucky...:teeth
