As I mentioned in my Malaguti Spidermax RS - log the last posting down the bottom Piston rings, my Spidermax RS with just 18000KM died because of the well known failure for a particular time period when the 500 MASTER engine changed from 460cc to 500cc and certain parts like original rollers went to really low quality crap what actually could break (pictures here in the blog) and low quality piston and piston rings. With this move you lost a customer for live Piaggio. No more 2 wheeler with a Piaggio engine for me!
Now I could get a kit with a new cylinder, new piston, new rings for around 250 Euro at some aftermarket dealer. I would have to dismantle the bike and open up the engine.
