can anyone tell me what is best for my mojave???

 

...... Best for you Mojave-- what would you like to do with it? There are a host of mods- one of the most noticeable would be ditching that airbox and snorkle, this will make the machine objectionably loud, unless closed course racing and the like are the intended use, a good aftermarket pipe would be desired as well. Other mods; a carburetor from a 300ex, acquired from Ebay, although it is a 32mm unit as compared to the Mojave's 34mm unit, it has an accelerator pump whereas the Mojave does not. If you were to go with hotter cams, oversized valves/ big bore kit and a KLR CDI box which has no rev limiter, then a 400ex carb would be the order of business because it's 35.5mm and has an accelerator pump as well.
