Malossi big bore cylinder kit 70cc Yamaha/clones w/o head

OK for racing! Big bore kits are unrivalled for increasing power and torque on your scooter engine. Malossi is Italy's famed racing parts manufacturer and designer, and a favourite cylinder maker of ours. Their cylinders are durable and quite underrated when it comes to acceleration and high RPM performance. Suits Yamaha 2 strokes 50cc with horizontal engines including: CV50 Jog (may need pre-emissions control exhaust, or performance exhaust to be fitted) Jog (all 2 stroke horizontal engine without emissions control) Axis 50 (all 2 stroke) Vino (all 2 stroke) and clones too including FYM Urban (not R4), CPI Hussar pre '03, Adly Silver Fox and RT50 plus most Chinese horizontal engined 2 stroke imports. Increases capacity to 70cc for more torque and power. Comes with big port cylinder, alloy piston (10mm gudgeon pin), alloy head, new pin and clips, gaskets. (Sample photo shown) This kit must be fitted and carb tuned by a technician or skilled person. Piston seizure is a symptom of poor carb tuning and claims regarding these kinds of problems will not be accepted. This increases engine size so that your bike may not be legally registered as a moped.
