the kit comes with a larger carb,38mm or 36mm for rec riding

 

how does the hollywood dirt production 240 kit compare to trengas, trinity, and vitos

 

Well I can tell you that the vitos will be at the bottom of the list, just because of the lack of port work they put into their cylinder. A 240 is only going to be as good as the mods you have to go with it. I.E porting, and a larger carb.
