I have a scored berrel and piston on my Pinasco 177cc big bore kit fitted on my PX125. I bought the kit last year and used the scoot for a couple of months problem free before I realised that the on going problem with gearbox oil dissapearing (seperate issue me thinks).
Anyway, I decided to order a new crank, bearing and seal set in the hope that it will rectify the oil issue. To my shock the pinasco kit seems to have a score on the barrel and piston. Now this was a bit of a shock becuase the scoot had never seized during the time I had ran the kit, and I am a little concerned that because the bore is chrome plated, it could have done some irriversable damage. the kit cost me £160 (185Euros) so I am not best pleased! Has anybody else had any issues with Pinasco kits?
Also, I have always been under the impression that alli cylinders with chome plated bores had to be replaced if there are any scoring, is this true?
