clutch slipping

Have noticed in the upper gears when I roll on hard in 5 or 6 the rpm
go but the bike has to catch up ..so went in for a clutch adjustment seems
much better ,then when I get to the desk they tell me the heavy duty
screaming eagle spring would be a good idea part 37951-98 ,any info and feed back would be helpful!!!!

I did cams and a few other mods ,is there a better solution for the slipping
or should that solve the problem

Make sure you don't have to much fluid in your primary. I put to much in mine and had the exact problem I drained a little out and it's been fine ever since as far as the heavy duty spring it's a simple process and you will notice it when you pull the clutch in and it seems to help out

Sounds pretty much like the problem I was having last year. I went with the Barnett Heavy Duty Spring and that took care of the slipping but the clutch pull gave my hand quite the work out. Add in the Clutch Wiz and the played with different primary fluids and ultimately I ended up replacing the clutch pack with a Barnett +1, keeping the Clutch Wiz and using the Evo Spring and moving away from Redline Primary oil. (The middle plates of my clutch were burned)

Absolutely should put the SE clutch spring in. Upping the torque and h/p with the cams and such dictate this. Don't slip anymore til you do it or you will glaze the plates and then will be putting a whole new clutch package in. I've had the SE spring in my other two high performance bikes and haven't had any problems with the clutch.

There was quite a bit of slipping going on
Hope I did not mess up the clutch I guess I'll have the dealer take a look when he is in there
The slipping was only in the high gears

The SE clutch spring and a proper clutch adjustment should solve the issue. If your clutch has been slipping a lot you may have burnt the clutch plates but I wouldn't change out the clutch plates right away, see if everything works as it should with just the clutch spring mod first.

The SE Spring should do the trick for you. Have the Tech check the plates during install to see if the slipping has fried the plates, otherwise you'll be going right back in there to replace the plates...

I've been milking the stock clutch with the SE Spring on "The Short Bus" it still slips a little in the upper gears (stout 117"), 'going to replace the plates and install a lockup when I get around to it...

I did cams and an exhaust and was having slipping like you describe. I did not want a harder clutch pull so I went with the Variable Pressure Clutch from AIM. Took care of the problem. Also can be installed through the derby cover.

AIM is the VPC / lockup that I'm going with. AIM makes the VPC for Screamn' Eagle.
