Don't get rid of those Clutch Tools just yet; especially if you still have the 1200 Basket. When they went to the 1300s (black basket), what they did was add a Hard Anodized coating on the basket to reduce ware. The only area of concern with all this surface treatment is the narrow little surface that the Friction Plates run on inside. Once those surfaces start to become rough, they deteriorate quickly into galled disasters which will actually lock the Plates fast. I have had to hand file these baskets for others who have the same vintage as yours. It's just a mess and the only cure is a 1300 Clutch and not just an old one. You look at the Friction Plate Bearing Surfaces inside the Basket. You also have to look at the Springs on the backside of the Basket. They can stand to be a little loose but when the slop gets to be in excess of 1/4", you know you are shredding the inside back of the basket.
You might get thru this riding season but I suspect you are going to need a 1300 Clutch by this Fall. You should start shopping for it now. When doing so, make sure you get the entire thing: Basket, Hub, Plates, and the 1300 Oil Pump Sprocket for the back and the Updated Push Rod with extra passages for oil.
There are many posts written here (Quite a few by me) about Transvers K-Bike Clutches. Look thru and read some of these. You will find them very helpful.
