    Yoshimura Cams for the 83-86 Suzuki GS 550's . Won a pair ..

    I won a pair of Yoshimura cams on E-bay for the 83-86 TSCC engined GS550's. Does anyone remeber these. What they gave for performance etc?

    Here are the specs:

    Grind #SUX121 these could not be found on the Yosh web site.

    Intake = 5.1mm stock is 4.83mm or .200" instead of .190"

    Exhaust = 5.1mm stock is 4.34mm or .200" instead of .170

    They also have Popy stamped on the cam near the cam gears. The lobes lokk wider wich means they have a higher duration correct? I also put my calpers on them and the lobes are slitely taller.

    Any help would be appreciated.
