ok starting out my wife has came to me and wants to race wheelers!!! but wants to be able to ride it normally, i do dirt drag and she wants to do it also so i chose a 300ex to start her out. well she has mastered all there is for stock power and i know she's gonna need more to hang with the big dogs coming next year so i found a few items for instance a 330cc big bore kit. hey it's a starter wheeler what do ya expect...but my worry is how is cooling going to be on it..for instance i run a yfz 450 and i have the athena kit which has larger jackets to cool it down and there desciption tells me nothing all it says is it sends you a new cylinder it is made by jci racing. any 300 fans out there please give me some tips.
