My s4rs clutch slipped with the stock springs when it was new and pretty much stock, I could hear it when twisting the throttle vigorously in first gear.  I replaced the springs with SS - don't remember which brand - kept the same stock clutch plates - and the slipping, or at least the noise (slipping noise or whatever) disappeared.  I remember the SS springs were a bit shorter but they were harder to compress.  I recently installed a slipper clutch using the same original stock plates and they still look pretty good.

I was a bit supprised to run across this thread as I had a related experiance the last time I changed my clutch pack.
Used a barnett pack and speedy moto springs. The clutch would engage very quickly, that is with the lever nearly touching the bar, but under heavy throttle would slip. The speedy moto springs "felt" stiffer but that may have been becaus I thought they were stiffer. I did not have a way to measure. The stock barnett springs were sitting there and looked a slight bit longer so I thought I'd just throw em on and see if it made a differance...it did! no slipage with the Barnetts?

Does anybody know what the life of the oem springs is? I'm still running the original clutch on my 95 with somewhere around 25,000 on it. Would I notice any kind of a difference by throwing some new springs on?

the springs wear depending on use. but new springs are almost alwya stronger than stock springs. i think speedymotos are atleast 25% stronger or around that much. so youll notice it eitherway.

So was there ever any resolution to this thread.  Was there an actual problem with using SpeedMoto springs with Barnett clutch packs?  This is what I just had installed on my bike today.  It's weird this thread popped back up on the same day.

i dont know what other people said, but the barnett guy was pissed of i was talking to the speedymoto guy behind his back.

Eitherway, i have speedymoto springs, and i went with OEM ducati clutch pack and all was well. The barnett ones were glazzzed all around. I didnt do any burnouts on them. but they did see rain a lot. which i think is the number one factor in why they died so quickly.

I've used several Barnett red clutch packs I got from Barnett and from Chris (Ca-Cycleworks) and they work well.  New springs in every pack and cheaper than OEM.

I'm thinkn I get 7000 mi. on a set maybe?

Takes 30 min. to change.
