    350x clutch slipping after 5 days?

    Hhey guys i just installed a brand new clutch kit with spiring steels and fibers...i put it in last week and rode it around fine ...everything was good sunday ...well i went out to ride it yesturday first lap around and it was slipping really bad...so i took it apart and found that my two outer frictions looked like they has some type of crud on the out sides where they would touch the pressure plate...well i cleaned it off and put them back towards the inside of the clutch pack and moved two others to the outside....i also noticed the new springs i got were like a 1/8 inch shorter then my old ones so i put the old ones in...any of you guys had a problem like this? or think it was just because of the springs were shorter?

    Did you soak the fibers in oil first and clean the coating off the steel plates before installing?

    Same mistake I made. Used automotive oil with friction resistant properties. That could be your case also, the shorter springs would be for stiffness I would think.

    what brand was the clutch kit? some of them come with some very feeble springs.. you might try putting the old ones back in.... improper oil selection can cause slippage... as well as a mis-adjusted cable

    I did the same thing with my Vmax, and soaked the fibers in regular motor oil overnight. Killed a clutch in 1 day.

    Taught me a very expensive lesson.

    Dude

    Its most likely not the oil you used.

    What did the original oil look like.

    I had gas getting into my oil damaging the clutches on my 350. Had to rebuild the carb. Ive known a few others with this problem. See if you can smell gas in your oil.

    I've been running "regular" 10w40 motor oil in all of my stuff for 20 years now. That's not your problem. Some steal's have a coating on em to prevent rusting while on the shelf, cleans off with brake cleaner. Pull the disk and scuff em up with rough sand paper and install the new springs.

    I would stay away from synthetic and high mile oils

    I haven't ever had any bad luck with a BARNETT clutch and soaking them in plain 10W40 oil for about a half hour. I've installed at least 4 Barnett clutch kits in a 350X, 200X, 250R (OEM set) and an XR200 come to my immediate mind. The same procedure was used every time.

    I WOULD NOT buy an EBAY clutch kit unless it was either genuine OEM or Barnett.

    What brand of plates and springs did you purchase??
