Clutch Slipping?

[vltor17]

Hey guys. So I've got an 09 XB12Scg. I put Klotz lube in it last oil change. I put the V-Twin Gear and Chain Case Lubricant in the transmission. Anyone else running this? The clutch seems to be slipping. It only feels like it on hard up shifts. It will still float the front tire for a while on a hard 1-2 shift, but I can feel something slipping. It will also chirp the tire on a hard down shift, so it's not excessive slippage, but I can feel it. I know its not the tire spinning. Clutch cable is adjusted correctly, need to look in the svc manual and see if there is any other adjustment on the clutch. Going to tear into it this weekend, and see what I can find.
Thanks
edit- It has 9 primary gearing, if that makes a difference.

Make sure whatever you put in the primary doesn't have any "friction modifiers". Fluids with that in it can ruin clutch packs and cause them to slip.

Also, check your primary chain tension. It could be too loose.

Ya made sure on the friction modifiers before I put it in. Will check tension, but I would think that would make more of a ratchet feeling (kinda like a track slipping on a snowmobile), than a smooth slip like I'm feeling. I actually kind of hope its the chain, I'm going to put the 12 gearing back in it when I crack it open. Thanks for the reply.

remove derby cover from primary. it is the lower cover held on by 3 screws....NOT the 2-screw upper cover. set cover aside, gently pull adjuster locking mechanism with spring out of clutch pack. that reveals a straight-slot screw. turn it out until snug, then in 1/2 turn. replace locking mechanism, replace cover, replace 3 screws. then adjust clutch cable to specs. having said that in conjunction with your comments regarding bike having a "9" primary conversion along with hard upshifts and hard downshifts...."tire chirping"....i suspect your clutch pack is in need of replacing.
