Since the picture shows a ZX14 -- here are some stories about our bike (Nancy's ride, #439).
Please Note That This Refers To SCTA Rules & Inspectors.Since it ran in production we could do dang near anything we wanted inside the exhaust cannisters as long as they retained stock appearance (well, the welder back in Japan must have had a bad day, if he's the guy that did 'em
). But they were close enough to pass without more than a giggle. As to the outlet ends: We retained the stock bits, but - on the advice of the M/C chief inspector at the time -- we drilled down through those perimeter holes through the baffle underlying 'em to hole it, too. That, he explained, was fine and dandy within the rules. Yep - the bike don't sound stock, no sir. But the outlet was bone stock appearing.
Lowering: We looked very seriously at this since Nancy's short in the leg department. And we found that the factory ground clearance - isn't easy to determine. I allow that I might have forgotten now - it's been a few years - but there isn't a factory measurement of the specified distance between the ground and the bottom of the bike. We found lots of measurements - but not one that we could reasonably expect an inspector to be able to use to determine how much lower we could get away with. So - we didn't do anything.
I mean -- we weren't allowed to substitute stainless braided brake lines even by claiming they offered no advantage in LSR, so why bother trying to ask for a definite ruling on a spec we couldn't prove that might well help top speed?
