Yes it seems most of the ultimas have noisy lifters, you could try to make sure you adjust them on the heel of the cam one at a time instead of at TDC this seemed to help a bit but still noisy.

Noisy, they almost sound like solids!!
Its all together now, no leaks, smoked the rear tire without trying. I will have get used to the starting method using the enricher/compression releases and throttle squirt. Guess I got spoiled by the fuel injection.

I have an S&S 640 cam and some 1:1.65 S&S roller rockers with S&S lifters. I know the 124 S&S engine lifters are quiet so my plan is to try this combination and see if it works, along with the normal checks (cam gear back lash, push rods rubbing etc etc)

CB, before you change the cam try this. The hydraulic lifters have about .200" of travel, adjusting the pushrods to their reccomended setting lengthens them about .100" or about the middle of the lifter travel. Now if you check your cam specs you will see when you adjust the valves at TDC, the lift is over .100", so you actually have a clearance of what ever the number is causing noise. If you do not have the pushrod at zero clearance then it will be worse. The mantra of adjusting valves at TDC started years ago when cam profiles were almost round, a lift of .300 was a lot and durations were nowhere near what modern cams are today. E-Mail me your phone number and I will explain what we do to minimize noise. You will still have some if you have a cam that makes real HP, but it will make as little noise as possible.

I don't adjust them at TDC but on the middle of the heel of the cam (zero lift), yes it does reduce the noise but I want to see how the S&S stuff works as I already have it. If I ever get out of Saudi Arabia it will get done.

I adjusted the valves per 'Heel of Cam' method and it now is just as quite (or noisy) as my 80ci w/Stage 2 cam was. Also found out some interesting bits about the Barnett clutch. Seems from other blogs that non-syn ATF works the best, at first I used regular primary oil and had some slippage. I used just enough ATF to supply the primary chain with lube and the clutch is now easier to pull, has no slippage etc. All I need now is for the weather to return to rideable temp at night. I ride daily and work 2nd shift.
Thanks to everyone for the help!!!

I found royal purple ATF the very best to use but I am running the S&S clutch. I tried the Mobil 1 synthetic ATF but it wasn't that good but the Royal purple is amazing I fill it right up to the clutch basket. I can pull in the clutch just before the light changes and sometimes I even have to rock it so it will go in gear with no clunk at all, can't even tell it went into gear sometimes and no slip ever.

I used the Royal Purple also, I just put in 1 qt. . As for the carb, I havn't put enough miles on yet to mess with the carb, so far the throttle response and settings are ok. Warmer weather should yeild better knowledge.
