First off, sorry to disappoint ya'll with nothing to bring to the table in this thread. Really what this thread will be about is the acquisition of knowledge and a collaborative of minds here on what I'd like to build in the future (after that first time home buyer bill slows down.) The basic question would be: What is the cheapest way to piece together a Bultaco TSS racer? A REAL TSS will cost quite a bit of change, of course. What I'm looking to do is pull a frame from one of their street models, pull an engine from another (I know the matador engine is close to metralla spec) and kind of piece together a cheap franken-taco to take out to track days. So what would be the best and cheapest frame to steal from and what would be the best and cheapest engine to steal? Liquid cooling would be cool but I think only the TSS really ran those engines? That would be majorly expensive. We'll throw some pics in along the way! Join in on the conversation with thoughts and what not, please!
