Ok, so I got this bike I a trade. Its a blue targa LX that is just a pile. I thought I could scavenge like bulbs and cables and whatever, and I noticed it didn't have a dellorto. Also I noticed the cylinder was smaller than my stock ones, so I assumed its previous abusive owner shredded his og cylinder and put like an a3 cylinder or some such thing on it. Then after I had it for a day or so I noticed that the biturbo on it has been modded to fit said cylinder, so then I began to wonder what the deal was, as it didn't seem likely that someone would go to all that trouble for a jimmy jigged cylinder. Anywho, the only markings on the whole shabang is the word "EUROCILINDRO" in tiny letters underneath the carb side of it. It appears to be aluminum and the piston has only one ring and is meant to have only one. The stock head works on it. I didn't have the foresight to measure the piston when I had it apart because it hadn't dawned on me that it might be of use, as I had given the engine up for dead. I got it running but the clutches are fried. The carb has ARRECHE written on it. WHats the deal? I don;t have a camera so pics aren't going to happen, sorry.
