Would not think so
NOTE! AS AN ADDITION TO MY NUMBER ONE POST AFTER A FEW MORE DAYS OF TESTING I AM SLOWLY KICKING AWAY THE % OF NO CLUNK ENGAGEMENTS. STARTING TO LOOK LIKE MY ORIGINAL CONCLUSION IS NOT HOLDING UP.

END OF START UP FIRST SHIFT CLUNK !? - FINALLY FIGURED IT OUT !?
You read about all the different ways to end the clunk you get after your bike has sat awhile and you start it up and it clunks going in first. I ride year round so thick oil in transmission, thin in primary is not the answer for me and I keep my clutch adjusted with very little play. All the silly stuff about pulling the bike backwards and hold the clutch for 30 seconds and yada - yada - yada. Tried most of these things but had pretty much ignored the clunk since my 04 has 40K and shows no sign that it actually hurts it and I have had the clutch basket off.
However I have discovered what appears to work for me and its shift so quite most of the time I find it hard to believe its in first.
My way. Since my bike is FI and I have a tac, upon startup I just wait till it drops to 1000 rpm or so, pull in the clutch, blip the throttle ever so lightly (kicks up to 1200-1400rpm or so) and as it drops back to 1000rpm or so I shift with a good stab to first. I swear it does not even make a sound going in. I cannot believe this is not in manual.

A compensator sprocket that eliminates transmission clunk...that`s a new one. I think I will have to disagree with you.

compensators and the normal "kachunk"
We have replaced the compensator with SE units on both our family Ultras. Our stock compensators had been tight and working properly and the change had no effect on routine shifts.. (they still "kachunk" loudly). My son reports his bike is now smoother at low rpm, however... go figure that one 
The SE unit and the stock units are similar design ramp compensators with the difference being a stronger spring for the SE to handle higher torque loads... both appear to only have effect when slam shifting under load and not when making light load gear changes. The stock units on our bikes had never "bottomed" (revealed from wear marks on the ramps) so their capacity had never been exceeded.
The only way we can figure that the compensator might affect routine shift noises is if the primary chain tension changes. It would be interesting to know if anyone has tried playing with the tensioner slightly and seen any effect on the "kachunking".
As always, I'm just saying

Thanks Dan, colonelangus must be another tin saleman's. Sure not going to use Jerry Seinfield's yada yada yada anymore. Also to own up to colonelangus statement [so whats the difference between your way and the way you described yada yada yada..seems like you way is just another funky way to start off]. Appears SO but I thought I had already said it in post 16
