    Hydraulic cam chain tensioner and high-flow oil pump
Rated 4.5 out of 5 by 6 reviewers.
Rated 2 out of 5 by Camplate,oil pump disapointment. I had 15k on bike when I bought it so I had it checked by local HD guys and found a little work was needed. So I decided to upgrade a few things while we were there. I went with the 583 EZ start cams from S&S and the Cam-plate upgrade from HD complete kit. Big bore kit (97") ,trick heads from J.E.T. ,S&S roller rocker, Fuel-Moto adjustable pushrods, S&S duel filter intake, Bazattie 2into1 equal length pipes, Power Commander V. From day one of picking up bike had low volume tick from upper end. After having bike gone over by local High performance tech, found rockers not clearanced for end gap. Corrected and noise got less. After 17k noise was unbearable on top end and oil pressure would drop 18lbs.while at steady RPM on flat road, an drop to 4-2lbs psi at stop. Back to shop finding SE cam-plate pop off warped and sticking. Talked with HD, So sorry Charlie over 1 year old and nothing we can do but sell you a new one.. Guess what is not going back in my motor?? Be warned to check more often when you hear noise..... September 4, 2016
Rated 5 out of 5 by Bike sounds great I ride a 06 Fatboy and at 30,000 miles OE tensioner was shot. Knew this was going to happen so had the HD shop in Bowling Green, KY replace. While in the cam area I had the 211 SE Cams installed, a super tuner and dyno tuned. Love the way bike sounds and rides. Recommend all these products. Couple of months after, went on 2,334 mile ride and bike ran great. Only issue was with bigger cam MPG dropped 2 to 4 MPG, but expected that. August 30, 2015
Rated 5 out of 5 by Engine runs great! The added oil volume with the larger oil pump is a plus. Installed by my local Harley dealer. I feel the difference in the way the engine runs better. I like the idea of the larger oil pump for increased oil volume. March 22, 2015
Rated 5 out of 5 by Worthy upgrade In all honesty, the newer spring loaded pads will last for many miles. But, the piece of mind you get with this upgrade makes it worth the investment. The SE oil pump is awesome. My 2005 RKC now runs cooler and quieter than ever. I did a cam and 95 upgrade at the same time and now look forward to adding many more miles touring our beautiful country and Canada. November 13, 2014

In the kit there is not an o-ring or gasket and the PDF refers to the owners manual when installing the pump which specifies using the o-ring in the Cam Service Kit (25533-99A). Upon inspection of the parts there is not grove for this o-ring on the new high flow oil pump nore is there one in the cam support plate. I thought perhaps there might be a gasket that I needed to purchase.

Answer: 
Hello 04FLSCT,

You do not need an o-ring or gasket in between the cam plate and oil pump. The surfaces are flat enough that you do not need either one.

Thank You!

If I do this upgrade, I might as well upgrade the cams while I'm in there. Which cam would give me a little more torque and a few ponys, while being very streetable. I want to stay with 88 ci at this time.
