Traded bikes last week. The new bike is a RK Custom. PO installed SE MCR heads with 95" pistons and jugs. The PO isn't reachable.

I called the HD dealer who sold the bike, the mechanic told me the bike has S&S Gear Driven 503 cams.

I can't find any S&S cam's online with lifts of 503, so I thought I'd put it to the group. Anyone know of 503 cams? S&S or other? I'm avoiding temptation to tear it down myself just to take a peek.

Appreciate any insight.

 

How about 583 cams? May sound similar if you were talking on the phone.

 

Could be. I'm assuming the MCR's can clear .585 of lift.

 

The 583 cams are bolt in, as are several of the other S&S cam sets.

 

10-4, appreciated the insight.
