I was out at Cal city yesterday fighting the crowds. The BLM had a check point on the 20 trail just east of the 20/30 spilt. They were checking registrations and spark arrestors. I got a spark arrestor ticket. For further reference it is for $60. Now here is the thing. My bike has a spark arrestor. It is a 1993 Honda XR600 with the stock pipe. The pipe is clearly stamped HONDA KRIZMAN SPARK ARRESTOR MODEL 701. They put the rod in and it went in. It's like they were testing for a screen type arrestor, but this unit is a Kirzman and has no screen. Krizman spark arrestors work like a Dyson vacuum. They spin the particles out of the exhaust stream. Since it was only for $60 I didn't really feel the need to argue with the officers. It was getting dark and one of our riding group had no headlight. Can I fight this ticket and win? What do I need to show to a judge to convince them that the BLM officer wrote the ticket incorrectly. If I can fight it with a letter I will. If I have to drive a long way to fight it, fighting will not be cost effective.
