Hello ! I have some 440 parts such as cylinders/head/pistons and such. Could be interested in the engine swap. Where are you located ?

I know that Yamaha did have an update on the flywheels for the 440 SRX, but I think it was for the 76-77 SRX's . I haven't heard anything on the other year SRX's..

yeah i have never heard of a flywheel update on anything 81+ (vmax or srx that is)
