This kit must be fitted and the 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 your engine size to approx 70cc so your bike may not be registered as a moped in NZ.

best bang for your buck product available. Power and torque increase across the rev range.
Great quality product, big torque increase across the power band (need to be careful coming out of the corners in the wet or damp conditions). I used to struggle to maintain 50km up hills but now I cruise up at 60-70km easy. Feels like an increase of at least 50% in power and torque. Extras to consider when purchasing this product: Delimited CDI, for the yamaha engine 4.7grams roller weights, stage 3 clutch springs and hard centre spring asked if course correct jetting.
