At a race this weekend, we had to pass the CA forest service sound check. I have a 01 wr250F with an e series pipe on it. Sadly, at the max power setting (12 disks)it did not pass(101dbs). at 8 disks it did not pass(98dbs) once I reduced the exhaust disks down to 6 disks it passed.(96dbs)
I had 2 major gripes with the forest serivces test.
1) They insisted on testing from the side on all bikes. The E series sound and exhaust comes from the side (like the old super traps.) There were bikes that were passing that were alot louder than mine from behind the bike ( I was in line behind them) when I asked them to take the reading directly behind the pipe they refused saying there regs mandatate a side test. :think: Just an fyi for any potential pipe buyers out there.
2) The rpm guide book only went up to 2000. For 01-03 bikes they just guessed. :think:
It was a real hassle dealing with this on race day. Several guys where sitting on the side fevorishly working to get there bikes to pass. testing and retesting. There were many who were turned away completely and not allowed to race.
Most of the hassles were with 4 strokes, the high pitched ring a ding 2 strokes where passing right and left. I might have to buy a less clean burning 2 stroke to ride in the forest. The EPA targets 2 stokes and the forest service targets 4 strokes.
Heads up: the MAN is coming to a trail near you :whiner: :flame:
