When to Beef Up Clutch?

A complete factory big bore upgrade from 88" to 95" included cylinders, pistons, SE203 cams and the SE clutch spring. Pretty obvious that the factory figured that increase in power would over ride the stock clutch. Should provide a baseline.......

Is this the case with heavy touring bikes too? I've got a 2013 road glide custom with SE204 cams. Stock clutch diaphragm spring supposed to work ok without slipping?

With a properly adjusted clutch it should hold... (IIRC the stock Spring is 300#) that being said, the next step up would be a CVO Spring 340#, (you might find the CVO Spring free/cheap from a CVOer that changes to the 380# SE HD Spring)

I think it will hold for a while if cams are the only upgrade. The stock spring would not hold my 95" Deuce (lighter bike) with SE204 cams but I was running more than stock compression. The stock spring started slipping at about 2500 miles and was replace with a VPC. The SE spring probably would have held but it had a heavier pull than I wanted.

Put your bike in top gear (5th, 6th, etc.) and let out the clutch with the bike running from a stop.
If the bike doesn't instantly die, its time for a new clutch...lol
Edit: Or clutch springs.
My old S83 had 15k miles and the clutch started slipping hard...read on the intruder forums that the springs are garbage but the disks are good for 100K miles...opened her up and sure enough that was the case...new springs and she ran like new.
