Question Clunking when rolling bike

hey guys, i have a 95 vn750 with 23k im working on for a customer..had to replace the pulse coils (and remove the engine due to the PO CUTTING THE FRAME on the left side to attempt to remove and repair the pulse coils, i know, WTF!) Anyhow, according to the owner the bike rolled and rode fine and smooth beforehand...but the guy seems a bit..daft ..so idk. Anyhow, i get her all done and roll her off the stand, and lo and behold there is a clunking coming from the driveshaft tube 6 times per rear wheel revolution approximately.So i pull the bevel drive of and check it, TOTALLY smooth. I spin the output shaft..same thing..LIKE BUTTER. Check the U joint..again, PERFECT. Lastly i pull the rear wheel, as the sound seems to be coming from there..Spin the driveshaft by hand with the wheel off, bike in neutral..Smooth as silk..Spin the rear end..totally mint also...But put it all together, and clunk clunk clunk.Ive checked every single part, YES there was grease on the pinion splines and coupler,and they dont look bad compared to pics i have seen.I greased the splines anyway.Ive checked every microfiche and i'm not missing any parts...spent hours and hours researching the whole spline issue and disassembly/ reassembly..i am convinced i've done it all correctly.. I considered maybe i need to phase the driveshaft, but theres only one u-joint, so it would seem that it's not necessary..I'm banging my head on the wall and the owner swears it was quiet before, but he has only ridden it for 15 minutes since buying it...sooo WHAT GIVES?!?!?!? i need help here as the owner is getting antsy and i need an explanation..And when i say the splines look ok, the loaded edges of the pinion male splines have a tiny bit of peening but thats it, i havent gotten into the grease too much on the coupler but it didnt look horrendous..the spring is there, etc etc
THANKS

HahA my apologies, no i'm a small shop that mainly does cars, but i'm in Brentwood NH, I'm 30 years old, have owned a number of ATV's and dirtbikes as well as streetbikes.My two babies are a 98 dr350 dualsport and a 99 Honda superhawk. My shop is called Whiskey Throttle Customs and I've done a number of full rebuilds and restorations as well as anything in between.
