Oh ****. My bad. 1994 sporty. Unknown miles on the motor. Stock clutch as far as I can tell. I guess the easiest way would for me to ride it and see if it slips. Was just curious if it's common practice to upgrade the clutch with the 1250 kit.
I don't think you must on a 1991-2003 model, they use the same clutch spring on 883 and 1200. I did not touch my stock clutch when I did the 1250 upgrade on my 1991. No problems with slipping at all. 2004 and later 883 uses a weaker spring, so you must upgrade.
