    Well, my clutch is slipping. When I'm just cruising around, taking it easy, it does ok, but if I start off fast, or just roll on the throttle hard cruising down the road, it slips pretty bad. So I was thinking about my options, and I was wondering if y'all thought maybe new springs would help the issue? If I replace the whole clutch, I'm going with the Barnett springs anyways, but I was considering just changing the spings first to see what happens. I mean, I guess it is possible that my springs could just be worn, I have a little over 17k miles on the bike. And when it starts slipping, I let off immediately to prevent it from just sitting there slipping all day.
    Am I crazy to hope the clutch itself is still good? Give me your opinions, what would you do. Thanks guys!

    Its going to cost you 3 quarts of oil and a gasket to find out if it's just the springs. Still a whole lot easier than a clutch.

    well, if youre there, its almost as easy to do the clutch as just the springs. im curious as to what kind of riding you do? i have almost 40K on mine and am noticing very little slipage. i cant even tell for sure if it is. i would first inspect the friction plates, if they still have some wear, you might just need an adjustment and you can keep on rolling for only the cost of the oil and gasket. good luck

    Time for an oil change anyways. I may try just the springs first.

    Well, I ride it kinda hard, but it was after I took it racing a couple times that it started slipping.

    If it's time for an oil change anyhow, it could be the oil. But why not go for the springs. As you know, it's an easy job. I think the gasket is like $10,00.

    Kirk, I just don't believe the clutch needs replacing at 17K. The Barnett Springs will make a difference in the clutch apply, but I don't think that is your problem either. Just went through the same thing on the HD. Clutch seemed to slip, and the friction zone seemed wider than normal. Could not adjust out with the cable. I have a factory service manual, but I ordered an aftermarket manual (I believe Clymer) that was on clearance because sometimes you just need a better picture. While skimming through, I found another clutch adjustment that was recommended but I had never made. There is a bolt in the middle of the pressure plate that adjusts the push rod. The cable can only adjust the amount of pull on the push lever assy. As the clutch discs wear, the push rod is still in the same position as when they were new. The clutch springs push the pressure plate towards the rod as the discs wear, but after a point, the push rod begins to keep the pressure plate held away from the discs. The HD has 36K on it now I believe. After adjusting this, the clutch feels like brand new. On the HD, you ran the screw in until you just felt tension, and then backed off I believe 1 1/4 turn. The screw had tension on it when I checked it, so I had to back off and then turn in to adjust. That much wear.

    The factory service manual for the V-Star I have shows this adjustment here also, but is not very clear on how to adjust. It just says to line up marks from what I can read and is not clear at all on procedure. You will put slack in the clutch cable, loosen the locking screw, and then adjust the push rod.

    The parts I am talking about are 15 through 19 in the clutch diagram. Maybe you have or someone else has an aftermarket service manual that gives a better description of the adjustment. The factory manual has the min thickness specs for the discs as well as the min height for the springs if you need them. Maybe someone else here has done this, or you could hit Mikey up for some procedures, as I am sure he will know what specs are or tell you that I am full of it. Either way, the parts diagram looks like it operates in the same manner and I believe that will solve the issue.
