Cool Head vs milled stock
#1
I have a 86 TRX250R..I'm getting ready to up my compression from my current 182 to around 215..and run better fuel of course..My question is should I fork out the money for a Pro-Design Cool Head or similiar, or just have my stock head re-worked? What are the advantages of the Cool Head...Thanks...Dave
