We recently did an S&S 465 gear cam & oil pump upgrade on Popeye's 2019 Harley Street Glide special with the 114 ci Milwaukee Eight engine. We filmed this project in detail over several days. That detailed tutorial video will eventually be released on this YouTube Channel. In this episode, Lurch and I talk about the project and also give our opinions and thoughts on the bike's performance after installation. Is it worth it? We also talk about tuning the engine to the new cam.
There are many cam manufacturers out there, and there are just as many cam options. After talking with some of our Patron Members in the members-only Law Abiding Biker Facebook Group, Popeye decided to go with the S&S gear drive 465 gear torque cam. We have no affiliation with S&S, but we definitely recommend them. You can get the kit Popeye used HERE.
A torque cam offers on-demand throttle response from low to mid RPM at cruising speed. A power cam targets high RPM, wide-open throttle response that keeps pulling right up to the redline.
You can go with a chain-driven cam or a gear-driven cam. You need to measure your pinion shaft runout to make sure it's within specifications for a gear-driven cam. The benefit of a gear-driven cam is you eliminate the chain and chain tensioner.
We tuned Popeye's bike with the Vance and Hines FP3 and it runs like a raped ape. Tuning was easy with the FP3. We selected the intake, cam, and exhaust for Popeye's bike and flashed it. After flashing the “canned” map, we ran an auto-tune session with really dialed things in. Due to Environmental Protection Agency (EPA) findings and Federal Trade Commission (FTC) settlements, the FP3 may soon become a thing of the past. We grabbed up a bunch of FP3s for you guys. You can get one here: Vance and Hines FP3.
