Post subject:  XB12 Exhaust Valve Actuator

I finished fixing my exhaust cable this evening. Normal mountain bike brake cable is too thick, but gear cable works OK. When I was disconnecting the old cable I noticed the cam on the top of the exhaust valve actuator was in a strange position (too far round), so I opened it up to check the gears. One of the gears appears to have a piece of plastic broken off , although I couldn't find the broken bit (the unit is the older one S0138.1AA). So does any one have a spare actuator they want to sell me?

I'm starting to think that buying an after market silencer might be a cheaper option if I can't get a good second hand actuator? But I don't want anything too loud or that affects the rideability of the bike.

thanks

Thanks Pash, yes it is the big gear attached to the cable shaft has distorted and it looks like a piece of it has broken off. I was aware that the Ford part is the same, but was trying to work out how to swap the Buell cam / cable attachment over? I'm still considering an aftermarket silencer, after watching a few videos on aftermarket exhausts, I like the look of the APH one:

It doesn't seem too loud and looks well built, it also means I can do away with the whole exhaust valve setup too removing any repeat of the cable / actuator issues I've had recently.

Hmm, decisions..... I think I'm still going to try to get a replacement actuator, even if it is for the short term, so if anyone has one they want to sell please let me know.

Looks like a common issue:

The place mine has broken / distorted is the same place as the photos on these forums:

Basically the black part on the shaft has jumped past the tag on the gear that is supposed to retain it.
