    Okay well im a new user on here and when i peddle up to speed and let out the clutch the motor isnt turning over, i have the clutch flower nut adjusted as tight as i can get it and the bike still be adle to move freely with the clutch lever in. Does anyone have any ideas of what to do?? The clutch pads only have like 150 miles on them.

    150 miles is plenty to wear out the pads if you ride the clutch too much.

    First, the flower nut is not for adjusting clutch tension.
    Why did you "adjust" the flower nut to begin with? Was the clutch slipping before?

    P.S. if you rode your clutch enough to wear it out in 150 miles, you'd have seen a lot of smoke.

    I found the proper sequence is loosen the cable stop and if it still slips only then screw with that flower nut. Adjusting the stanchion collar did little. Also do not remove the spring between stanchion and clutch arm as has been suggested here. And don't hurt to sand/clean pads and make sure they "float" while you're in there.

    Personally I don't think the pads wear fast even on my slant head with SBP pipe. Almost 2k miles now and they looked good when I checked last week. I don't pedal up to speed like I should either. Also my oldest bike has no compression but the clutch still ok after 14k. Very surprising considering what they are made of.

    The flower nut is used to adjust the area or span of engagement, not tension.

    If your clutch is slipping, tuen the flower nut back out to where you started, clean the pads as suggested above and finish them off with a shot of carb cleaner or brake cleaner. Then make sure your cable stop is just not too tight as xlite says. If it still slips, you will need to adjust the collar inside the case (easy, takes about 15 minutes).

    Wore out my pads in less then 100 miles easily. It helped to adjust the flower nut and all the other stuff for awhile, but wasn't long ordering new pads. There cheap like everything else.

    You must be very abusive to the pads, or your clutch was not adjusted at all correctly.
