    Yamaha Vintage Pipe

    So.... going to run a vintage event at Avon NY...
    Have a old period correct Yamaha (mild stock appearing) and a T1 pipe.
    Any suggestions on pipe settings or a different pipe.
    Appreciate any suggestions... been a long time since I fired a Yamaha.

    We run the RLV L2 pipe, and that seems to be what most others run too. It's not "vintage", but I've never heard any complaints.

    This guy in California, used to work for me, still has some new cones for my bullet pipe at his shop. He can put one together for you, and it's really vintage, from the early 80s. I don't think he sells them real cheap, but talk to him. The quality of his craftsmanship cannot be exceeded.

    In any case, the pipe was developed for the KT100.

    The always safe start is at 9 3/4" to 10" from piston. let the temp be your limiting factor and the stop watch be your guide.

    Old style head under 400
    New style under 500
    I would look for 14500 but the stop watch is always the final answer to gear

    Old Style Head Temp shouldn't exceed 420 degrees.
    New Style Heads shouldn't exceed 460 degrees.
    You can turn them 15000 RPM

    I still have a pristine Mayko L pipe I hang onto for someday. I think it was a good torqey pipe back in the day. Al, what say you?

    I think Al took his spreadsheets and theories and ran after supposedly a ban from the setup forum, he announced a goodbye a week or two ago
