Hi,
I’m just getting ready for another season of racing my 250.
I’m a bit short on cash but I’m trying to build up a spare engine, doesn’t have to be as fast as my main engine but I’d like to have something to use in an emergency (i.e. if I have an engine failure 
).
I’ve got an engine in bits nearly ready to put back together but I’d like to put a higher compression piston and hotter cam in it rather than using road standard ones 
Has anyone got anything available which they’re not using / don’t want? 
Preferably going cheap as I’m nearly skint and I’m going to have to give Maxton a big wedge shortly as the’re doing my forks!
Cheers,
Roger
