The problem with most local tuners is they really don know squat about 2-stroke tuning, they simply make the inlet & exhaust port bigger and fit an exhaust with no caliberations. The ports need to be bigger but the angle and smoothness of the ports matter a lot and then the exhaust needs to be an exact match. So a lot of math work needs to be done and only the most knowledgeable tuner can make it wok to perfection. And then comes the carbs, jetting, reeds sprocketing ....etc. Skill is second to wisdom. |
