96 to 106

[stupid_rope]

heat cycled my new S&S 106 last night. went for an easy ride. here's my issue: when i get on the throttle, the motor makes a loud tapping noise. it idles and revs fine - it's just when under load. so....my first thought was pushrods need adjusting (rockers hitting rocker box).

any other thoughts? ill pull the rocker covers tonight and look for scarring

What cams you running? how did you adjust pushrods?

same cams as before, TW-555. 19 flats on the push rods. im gonna go pull the rocker covers and look. hopefully it just needs adjustment

Gear drive or chain drive?

just pull the plug and run it up...check for play lemme know if you need a hand

thanks bro, i found the issue - blew a head gasket. other than that, engine runs great. im sending the heads to Big Boyz today for port, polish, and comp releases, should have them back next friday.

lol even with the blown head gasket, I was pulling 98/106 on the dyno...can wait to see what she does after the head work and reassembled
