no other mech changes.  Same cam, same tune, if they are hitting the tubes what sound does that make?
I don't think it's pinging. I'm running a Dynojet PC3 with 812-025 tune. It did not have this kind/level of valve train noise before lifter/PR install

I had a new belt put on at the same time as well. now Im reading about compensators? WTH is a compensator? and what kind of noise do they make? Could it be that my lifters are quiet and im hearing this compensator thingy? my noise is differently load related

There is no down side to using limiters whether you need them or not, as long as the installer knows that's what is being installed /u]they are adjusted properly.

Part of the problem with limiters is dealer techs may not be familiar with proper adjustment, you alluded to that.  While I agree that limiters really help with "hot start/bleed down issues", I find them noisier with than without, and a stock compression 110" properly tuned with the timing reduced in the start up tables if needed, don't have a problem hot starting. When I had a hot rod carb'd motor I used limiters.

it sounds like you also defeated the 02 sensors and are running it blind

are you getting the noise at different elevations from where you set it up? or are you always running at about the same elevation  - the new engines rely on the ecm to account for various elevations  carb bikes just smoke... efi ... well - it could be knocking.

also - 07 110's had valve cover clearance problems and would smack the valve covers.. and they run hot - folks do all kinds of things to make them run cooler, often causing other problems  and all of those issues will cause noise.

more or less sea level to 1500ish elevation.
Yes the O2 sensors are disconnected
If it had a Clearance issue under the V/C would it not due it at all rpm's

Bump

[*58Vette]

  I was running the limiters with a woods cam.  The engine and I didn't like it (noise).  The lifter travel was limited and they would bottom out under load and hard throttle.  I removed them and have been happy ever since.
  When they did hit the bottom,  small pieces of metal would come off of 1 out of the four limiters.  That lifter would stick; it cleared twice.  Once was within a few seconds; the second time lasted a little longer.  I took it apart.  I disassembled them and found the problem.  Cleaned and reinstalled the lifters without the travel limiters; problem solved.
  The difference between adjusting them and removing them is 8 bolts.  Stock 110" motors don't need them.  If you want to adjust them, here are the links.  Removing them is only 15 minutes more though.

After reading and searching here and elsewhere on the net. I think the noise may be piston slap. It's always light load 2200-3200 and will go away with a little more or less load? I checked for pinging . Even tried to fatten up the fuel in that part of the map 22-3200.  If the lifters were bottoming wouldn't they do it all the time? My problem Gary's with load?

On edit it seems to be the front cyl only making noise

[popsracing]

Where did you buy the lifters and pushrods from??  J&P sells the quikee push rods alone or in a kit with the tubes...you should be able to purchase just the tubes either directly from S&S or J&P

[Camojeeper]

My local Indy got them for me

[hrdtail78]

Can you tell which side of the bike the noise is coming from?

[Camojeeper]

Clear as a bell right side front cyl.  Read about compensator failures on here but I must have got a good one 27,000 and no problems with it so far. Absolutely no noise from the left side ever. I'm thinking its piston slap in the front cyl.

Evo Industries has a sprocket that ends all compensator issues..........by removing it altogather.

I tried the Evo Industries 30t sprocket that has NO Comp. It was fine going through town but as soon as I got to 50 the vibrations started as my forearms started to get numb I accelerated to 65 and dropped into 6th and it was worse so went back to 5th and took it back and pulled the Evo Ind out and installed the first revision of the comp assembly and no more problem. I have an 07 Cuse and have stock gearing.

That's very odd, no different than someone with a primary belt drive.

Your experience is the norm for that item. I have removed many of them for that reason. In other cases I have tuned bikes with them and it can make tuning more challenging in the low RPM range. Others have had spline failure on the crank running the non comp. We had a crank here that had a very nice twist in it and we caught it in time before the damage went to the catastrophic  level Replaced the Jims crank and install stock comp no issues since then.

Myself would never recommend one after what we have seen first hand.   At least with a open primary and a belt you get some absorption  in the belt none with that chain. Even in a dyna I just tuned and rode its not smooth in low rpm parking lot type riding.
