    Hey guys, it's been a while but I have a timing question. I have an 81H with HHB PMA, Pamco with E Adv. new pistons, rings, head, timing chain and guides and ss valves and oil seals. The new top end was due to an exhaust valve that broke and dropped into the piston chamber. Not the issue...

    Warning: had 2 defective MikesXS advance rods.

    Amigos, Quick public service announcement and a request. Did the Hugh's Handbuilt PMA swap with the Pamco e-advancer. All went well. My bike is an 82 and didn't have the timing advance rod so I ordered one (part #14-0650) from MikesXS. Got about 50 miles on the bike then the rod broke...

    Quick question about timing and rotor marks.

    I installed the pma/pamco setup from mikes and made my timing marks as described in the instructions. The instructions say to make two marks on the side cover one is TDC, and one is at 15 degrees. The TDC mark gets transferred to the rotor. I assume that I will be timing it to the 15 degree...
