    I have just recently bought a 1987 Yamaha RD 350 (High Torque). I
    would like to fit a set of expansion chambers on these. Could anybody
    please direct me to websites which provide the calculations and design
    for the best power for the bike?

    Thanks in advance.

    Look at www.spec2.com You should be able to find all the information you
    could ever want for the RD/RZ.

    I can vouch for their chambers as I had used them on an RZ350. They used to
    match the pipes with a head milling service. They also offered a new battery
    box and K&N filters to complete the package.
