It was looking good for a quick jaunt out on the RS but instead thought i'd give my other half's the treatment of replacing the piston , rings , little end after we found that the slight running problem was down to the fact that the Power valve had caught the edge of the rings/piston and worn thefront of the rings down thus reducing compression - ran ok with lots of choke to compensate for some of the time but was destined to be pulled apart . well i took it to bits last weekend and ordered the bits and just earlier finished it and filled the carb and first press hey presto it ran sweet and now its just a case of putting bodywork back on bit of a clean and and happy partner (well i had a big barny with her and fell out doing it but think we made up when i showed it her going again !). Dont you just love it when things actually go right and even more suprising its italian .. what a bad design fault that the power valve can stick into the bore and catch the piston !!!. glad i found that out before re assembly.
