On my second S3, an 03 and an 07. New one has Scorpion cans and I couldn't be happier. I have been riding motorcycles since the 60's, to include a Maico, several Nortons, a Matchless, a Bultaco, a Buell, a Ducati and now the Triumphs. I'm a little confused by the break in method posted by some persons in this forum, namely no break in at all (just run the sXXT OUT OF IT) BECAUSE IT SEATS THE RINGS FASTER. This may be true but there is more to break in than just seating the rings. Every engine consists of thousands of internal sliding, rubbing and reciprocating surfaces that, due to tolerances and imperfections, do not mate perfectly. For this reasons quality engines are fit very tight. They wear in to tolerance. Due to the tight fit new engines run very hot at the mating surfaces. The more rpm, the more friction, thus more heat is applied to carefully heat treated surfaces damaging them. Once damaged these surfaces lose their strength. Once damaged these surfaces can wear very rapidly. An improperly broken in engine does run better faster (sometimes) because it is loosened up quicker and is restrained less by friction. The down side is that and improperly broken in engine with 1000 miles on the clock probably has the internal wear of a properly broken in engine with 20,000 miles on the clock. It will continue to wear at an accelerated rate due to damaged parts that have been softened by excessive heat caused by unnecessarily high rpm at the beginning of its life. Break it in the way the factory recommends if you plan on keeping the bike for a while. Most wear takes place in the first 100 miles or so but most engines and transmissions are not totallybroken in until they have 3 or 4 thousand miles on the clock. Until that time it is best not to sustain high rpm for any length of time as the heat generated by friction cannot be carried away fast enough and the internal can be irreparably damaged. The best way I know of to get Triumph to shorten their warranty is to promote trashing their bikes when brand new. :???: :???:
