Re: Best conversion forks????
even with a decent shock on the old type fork it will still need an anti dive to stop it botoming out, providing you can get the brake to work well enough in the first place

Re: Best conversion forks????
pkxl2 forks are threaded all the way up like a t5, pk50 forks are the same as the v range, pk125 forks are what you want, or any pkxl, the drum is good enough without a disc on the xl forks, the steering lock is also different in having a half moon cutout instead of a slot

Re: Friendly Late Night Debate About Transfer Ports.........

Re: PX 125 barrel upgrade
the dr is a bolt on kit and pretty basic, the others need the case transfers matched to the barrel and will benefit from more inlet timing, and you should be able to get 14-15hp no problem with a decent pipe and t5/p2 carb with the polini or malossi, i dont know much about the parma or pinasco the s...

Re: Recessed head
then get the barrel done and if at a later date the piston turns out to be taller you can just fit a thicker base gasket, thus keeping head and squish how you want
