I purchased a 2001 Yamaha YZ 125 for my 14 year old son to race. We would like to make some modification to it and I was wondering which of these products would perform better in this bike and what would be gained if anything. The Boyseen Rad Reed or the V-Force Reed Assembly. The Pro-Circuit Plattium Pipe or the FMF SST Pipe? Anyone have the answers?

Get the Vforce, period. No comparison. The SST pipe is good but the Pro Circuit pipe and R304 Shorty will add loads of bottom, good mid, and plenty of top!
