clutch problems

My clutch is slipping bad on my 5o cc 2 stroke motor. I took it apart and it looks like the 12 or so rubber squares are about shot. Can I get replacements? if so where?

I think Bicycle Engines, Motorized Bicycles, Bicycle Motors, Motored Bikes: 2-Stroke & 4-Stroke Kits! had them?

I have found the best place to get them is on ebay. Round or square. In the meantime if you want, glue something onto those pads like thick pieces of cardboard or those felt pads used for kitchen chair legs. One time I cut out a piece of cardboard and shaped it like a donut and placed it over the pads, even that will work for a few rides depending how you use the clutch. I really like abusing mine so I'm looking into cheaper and better ways to solve this problem. I bought a half inch, dowel making drill bit the other day and plan on making pads from old tires and worn out hard soled shoes. These bikes are a fun cheap hobby...gotta luv it.
