    Jeez why downgrade to a 22mm carb!? thats like the size of a 110 carb, stock is 24. Some reason im doubting that it has a 13.whatever piston.

    they used 13:1 pistons back them, the 22mm carb doesn't make any sence to me, I beleive curtis sparks sold a 28mm carb. I doubt that sparks rebuilt that motor either recently, maybe 10+ years ago he did. Didn't curtis sparks also use dual plug heads too? It does look like somekind of oil cooler is on it.

    dennis kirk used to sell curtis sparks 13-1 piston kits back in the day....so they are real

    the carb must be a miss print...could be a 32mm

    TC did the dual plug head thing...and more, he did some with 3 or 4 but but they were weak (cracked between all the holes)
    80s......185 atc, Yamaha tri-moto 200, 85 200x with tons of work

    I want those rear fenders.
    Not a bad looking bike, if it has what he says then it probably moves pretty good too.
