And cam plate screws 4741A,  1/4" x 20,  1" length.

Might consider using a stud and undersized 12pt nut at the 2 dowel/locator positions.

well the longer ones (1-1/4") MUST go in the cam cover BECAUSE if you use them on the cam plate you will put a really nice dimple in the lifter bore(s) and that will definitely ruin your day

If you want to switch to studs and nuts PM me your address and I'll mail you two each. I have a drawer full of them.

 :agree:  Studs and nuts in those dowel positions are something that that should be done to all cam plates if the cover is off. When I introduced my dealer buddy to them they had a stripped one in the shop and sweating the repair. The studs fixed it and gave a better fastener quality to boot.

The only caution about the studs and ARP nuts, is watch that aftermarket billet cam plates have clearance for the socket to torque the nuts. Test fit the cam plate before assembly.

Thanks guys, I just couldn't remember which went where.  I know about the problems if you use the long screws in the wrong holes and F up the lifter bore. Thanks for the offer on the studs, but I have done cams a few times and never had any issues stripping the two screws. I just torque to the light end of the spec on those holes.

Bike is back together and running. Waiting for spring to do some V-tuning with my TTS.

I have 18,500 miles on my '16 and opened it up to swap out lifters and decided to toss in a set of CR570-2 cams. Here we go down the slippery slope again! :doh:

Just curious, but since it is winter, why not haul the bike to someone like BVBOB and have it tuned? Yeah it's a haul, but a real good tune is night and day from a good v-tune. Been there and have the t-shirts.

    :hyst:

   here is a tip on the ARP nuts when using studs.
Put two nuts flange side to flange side on a bolt locking them together. Then spin the flange part of the nut on a bench grinder to make the OD less so it has no clearance issue going into the cam plate.
  I've got a socket made just for this application. I took the socket and spun the side wall OD down on the bench grinder too so it fits in the holes of the cam plate.

Yep, I never did either, until I did. And at the time I was using a very good SnapOn Tq Wrench at the lower end of the spec.  Fortunately I had enough threads below the stock bolt to locktite in a stud.

I have had two different bikes tuned by respected tuners and they ran great and got 25 MPG so I ended up V-tuning them anyway.  IMO a dyno tuner will get the hard to tune areas but the V-tune does a pretty good job on the rest. I have V-tuned my 2010 a few times because of different configurations and have been very happy with the results. A pro might do a better job on wide open throttle but I have been very satisfied with the low and cruise RPM.
I am an adult?? When did that happen, and how do I make it stop?!

My experience says a pro gets everywhere better. And unless you're measuring AFR, you really don't know where you are. It's your bike and your choice.

 :agree:   I have a beautifully running 113 that was street tuned (with widebands) but it took awhile to get there.  I have tuned several bikes since then, also with widebands, and I would never bother to do one with narrow bands only now.  While you may get the light cruise areas tuned well (as you mentioned) the higher load areas will be off.
