the cam timing can be changed to YZ timing pretty easily, plenty of other stuff to do the the engine like pipe, jetting, porting, high comp piston, ignition etc.. but I'd concentrate on suspension and handling first.

thanks mate, luke beechy sorted me out with the pep zps gear at a hell of a good price so the suspension is sorted it was just the engine stuff. what pipes etc is every one else using.
he also reckons most of the other guys out there are good to deal with as well which is a pleasant suprise from the dirtbike world. good to see you quad blokes look after each other

yup it's funny how different it is from the rest of the bike industry, Most of the guys in the biz get along well and are good mates.

So many options for pipes, Leo Vince, Yoshimura, DMC, Bills, HMF are all readily available and worth looking at. I prefer the Leo X3 FIM spec pipe just because its so quiet but if your doing MX you probably want to go for a full open system.
