anyone know where i can find the best, most powerful most reliable big bore kit for a 300ex. my friend has oe and is looking to get soe significent power out of his, if this is possible out of a 300ex. persoally i think that there must be some way to make oe faster than a 400ex!

 

i really dont see the point of boring 300ex's all ur gonna do is make it like a stock 400ex y not save all the money u put in the 300 and sell the 300 and buy a 400...thats jsut what i think the best thing dont know about anyone else's opinion
