Best upgrade for the money
You don't notice much except for a different kinda sound coming from the cam cover.BUT get up to 3k rpm and give it a wack,all heck breaks loose,hold on,your in for a surprise.
Made my 2003 FLHTPI so much more enjoyable to ride and I'm not thinking about when I have to change the cam chain adjusters anymore.

Great Products from S&S
After installing this cam kit in my bike, the motor seems to have a steadier idle and sounds much better. I am a retired mechanic with a well equipped shop, so it was not that hard to do. You do have to be careful in the installation.

Je l'adore
Très bonne combinaison de cams direct gear et pas plus bruyant que les chaines, fini les troubles de tension...facile d'instalation...Juste s'assuré de respecté la procédure d'instalation...Très facile...J'ai quand même donné une clairance de 30 millièmes tout le tour des lobs de cam...Ils n'était pas indiqué pour le 510 mais je l'ai fait pareil...pour me sécurisé.
J'ai un Harley Deuce 2003 monté 1550 avec les têtes porté flow bench, ressort et valves modifié.J'ai également remonté la pression de la pompe a huile avec le ressort https://fortnine.ca/en/feuling-pressure-relief-spring-individual-8018
