Has anyone used the + 4 degree cam sprocket with the Andrews 54h?  I have a 2010 Limited with the Fullsac setup; 54h, .030, X-pipe, CVO pipes w/2" cores, and the 30T pulley. I love the power (96hp/104tq) and gearing but don't trust the belt. (Broke one while on vacation this year. Ruined the trip for me and everyone else who stayed to help.) I am thinking of going back to the stock gearing and adding the +4 cam sprocket to bring the power I have at 3000 rpms down into 2600 to 2700 rpm range. Will this work?

Go ahead and add the +4 but the belt issue is caused by an Andrews pulley. QC issues are documented and the symptoms are broken belts. I have had no issues with the Baker 30T

I hadn't heard anything about the Andrews pulley being the culprit. (That is the one I have.)  I'll just put a Baker 30T on this winter with a new belt and call it good.
I've been told that the +4 cam sprocket shifts the torque band down by about 300 rpms. Do you concur? If so, I'll do that and check the cam tensioner shoes at the same time.

I agree, sounds like a plan
Another thought the triglide uses a 30T front, genuine HD

30T trans output sprocket, H-D # 83595-11, $74.99 MSRP.

You're the man, there is what I would run right there. I have a Baker on mine and it cost triple.

Thanks. You experienced guys willing to share info with the rest of us makes this forum great.

I dynoed the plus 4 sprocket back to back on a 54 Andrews in a well tuned 96". All I got were burnt fingers.
Was completely undetectable, zero gain or loss. Some cams work well going plus 4, but not all are good candidates for tampering.
Your 103 with .030s is right at 9.8 comp. Start closing the intake valve sooner than 40 degrees and you may see some pinging. And I've been
hearing lots 103/110 pinging stories this year. I'm not a chemist, but surely this new E10 gas is not taking us air cooled guys the right
direction. 103s, 54 cams and.030 head gaskets. Very popular trouble free combo right now.

PS- still looking at an idler pulley for the 30T that lets us use the stock belt.

Did you look at the Buell pulley?

Buell pulley? I have the whole dang bike! I already had the Buell idler pulley under the swingarm of the 09 checking it out. I really needed to tear the 09 apart and
put the stock belt back on it to fab up a bracket for the idler. The idler pulley on my LS3 looked pretty promising too. My 09 shop bike went bye bye Saturday
to a new home. Won't have my 2012 until end of Oct. I have no plans of riding the 2012 with stock gearing (or motor) so that's when the idler pulley project
will get back in development. The quick and dirty way would be to weld a mount to the bottom of the swingarm. I know for many, the thought of welding on
their new CVO will cause more anxiety than a male Pitbull sniffing their wheels. A bolt on arrangement would be prefered. I will figure something out.

Sorry for the thread jack.

Would agree on the +4 probably not worth the effort.
I have had the shorter belt on my 07 and have had it geared with a 30 front and now with that same belt have it geared with a 68 non-ids rear.

I agree with Steve on this. I've put 20k on my 103 since the Andrews 54's,.030, Fullsac set up. Flawless performance. Rock solid dependability. I yet have done the belt, but mainly because I don't feel the need with what I have now.

     Steve, have you ever tried using the +4 degrees on the andrews 55's cam? What where the results? and do you have any expierience with the 55's compared to the 54's?  Thanks.

Never tried a 55.

I finally got some time. Put on the Harley Trike pulley with a new Gates 139t belt. While I was in there, I installed the SE compensator.  I should be good to go now!
