I bought the Airsal t6 racing thermal group with single ring piston . The problem lies in the fact that the piston remains about 2 mm below the upper dead end. The squish is about 2.5mm. I mounted everything without gaskets. If I mount the gaskets iget to 3 millimeters of squish. I thought the piston that came with the kit is too short. Can you give me some information? This is the kit https://ibb.co/ZLQYSBn

Good evening, I have a 1993 mbk booster with Malossi crankshaft, airsal t6 cylinder and phbl 24mm carburetor. I found a new Yasuni R exhaust at a good price. What do you think?
