Prior to the Kymco, I had a Piaggio product that had a press-on cap on the outside of the clutch bell. Whenever shudder developed, all you had to do was pop off the cap and blast the dust out of the bell with an air compressor; it cleared up the problem immediately. When I bought the Kymco, I noticed shudder as soon as I drove away from the dealer, but hoped it was just some temporary condition resulting from newness. Since the Kymco has no convenient access to the clutch internals, I was worried about how involved it might be to solve the problem if it didn't clear itself up. Well, 8 years have gone by and the shudder it still there, but to a much less-noticeable extent; nowadays it doesn't seem to happen on take-off, but only occurs when accelerating lightly in a low-speed traffic crawl. Since the clutch has never been touched, I attribute the lack of significant shudder development to the fact that I always accelerate briskly on take-offs, thereby minimizing clutch slip.
