ah. you should take comfort from my story then. I had the same piston problem with my 500 LB Machismo after 200-300 kms and I tried replacing the whole bike fearing the manufacturing defect would continue damaging the pistons. But of course RE didn't agree and got my piston kits changed for free under warranty. Then I go on this Bangalore-Leh solo ride and the same thing happens in Udaipur. I was out of warranty by then so I paid around 14k replacing it. I was adamant to finish the trip so I broke it in on the way to Leh and got back to bangalore only to find the same problem again. This of course could have been partly my fault as it was doing high altitudes and the engine was running for a maximum of 2-3 hrs without a break, but I never took it above 80km/hr. So yeah I spend another 16k in bangalore replacing the piston kits. 2 Months later, last monday, would you believe it, I've got the same problem! And this after the most careful running in ever! So now I'm trying figure out how to take my case to the company. This obviously is an assembly defect which is probably mistiming the engine or even something more complicated which will not be fixed with just a piston replacement
