Front pipe AMC

Post  kerabo on Sun Mar 12, 2017 8:06 am

Can anyone tell me if the 25T front pipe fits the same as the 20T please.
I have a pipe that looks like it goes on the RH side of the bike but has a lip on it for what looks like a flange. The 20T goes into a slot with a screw. The Built in silencer insert looks pretty much like the 20T

Thanks Ken

AMC 25T exhaust pipe is held on with a flange and screwed on finned collar similar to Villiers fitment
AMC 20T is a push in exhaust fit, secured with a single screw through tab on underside of pipe
AMC 17T is same as 20T, but different bend to compensate for shorter barrel and different frame configuration.

If you have a low level r/hand pipe with a flange and FB baffle section it could be from a James or FB with a 25T engine
Cruiser 80, 84, or James commodore, all slightly different

another thing

Just to confuse matters and to be different , the AMC 250 25T exhaust retaining finned nut is the same diameter as the Villiers one, but a different thread pitch, so you cannot use the Villiers nut, you can tell the difference, because the Villiers one is rounded at the front of the fins and then parallel back from there, The AMC one has rounded fins which are bigger at the front and taper smaller as the go back towards the cylinder.
