Anybody have any ideas on where and how to pick original Mahle bore-piston kits and oversize pistons?
My Roadking purrs along beautifully until I hit about 80 - 90 kmh. Have got any number of compliments from random bikers on the road about how clean the beat of the engine is. At that point though (about 85 kmh) she just seizes. I bought the bike six months ago and I love her but this seizing has been bothering me. I'm no reckless speed demon but I like to know my engine is performing to its potential and the factory rated top-speed of the Roadking is supposed to be 120. So, I opened up the bore to figure out the problem and found that the piston is a local (unrecognisable one). Thought it might have been an uneven re-boring job but the bore looks just fine while the piston was burnt all around. Turns out the metallurgy is just bad and so expansion of the piston is greater than the bore causing it to seize.
Finally, I swopped the piston and rings with another local make but one which is very well known and costs more than twice any other piston. Vijaydeep Agencies on JC Road makes it. The set came with original Goetze rings so I'm rather happy about that. They are the best people to go to for re-boring since they use computer calibration to carry it out. Hoping the metallurgy matches the same standards. As of now I'm running it in for 500 kms and then I'll see what happens.
However, I would like to try and get a Mahle piston if at all possible and stock up on spares too. I'm running a .5 oversize now. Any suggestions?
