Hi
I have just bought a jtx 270 1997 i think
it has got a bottom end rumble, previous owner fitted new piston and ring i think
it has loads of compression which backs this up
I am interested at what my options are for a rebuild
it has pay in fly wheel
i must say i am new to the forum so not sure if you can give names of supliers
i use a trials shop in stroud
thanks graeme
