Piston help!

Postby simonkgk » Sun Nov 22, 2020 5:59 pm

Does anyone know where I can find a piston + rings for my 1959 Model 14 ?

Everything is rebuilt now and this has tripped us up!

Help much appreciated

thanks

Club spares seem to have collets as well.

Who have you tried?
Also

AMC Classic?
I don't know about L/W's but it's worth a call.
They list these........

Club spares have inlet collets (042150): http://www.amoc-parts.com/store/comersu ... duct=21836
If your bike has the early "thin" exhaust valve stem (same as the inlet), the exhaust collets are the same as the inlet ones.

If your exhaust valve has the later, fatter stem then you need 042870. Club spares don't have these, but I'm fairly certain they are the same as Triumph Tiger collets.

Good luck!
