Anyone had any experience with the prefab speed kits for the Tomos? I just got one on the cheap and installed on a friend of mines bike but to save myself the trouble thought there might be a few of you guys out there that has aleady mastered the carb setup for these and can tell me what the best jet size, needle placement etc you have found. This is a athena knockoff or eurokit cylinder and head, biturbo, and last but not least an Amal carb. I havent messed with these before and could use alittle help. It seems very boggy to me at bottomend and has troubles idling properly. All help appreciated!
