just bought this engine for my drift trike so its stock any suggestion on up grades? 300-500 budget. i would want it torquey. not familiar with the whole rebuild. this will be my first build. i would want to take the governor out. so i need to know what parts i need so i wont blow the motor. I was thinking a cam, springs, flywheel, rod, intake filter, exhaust, and jet the carb .Do you know what's a good set up with part number with a budget of 300 to 500? Sorry I don't really know which way to go with all the option they have for each item. I don't know what will work the best with each other to get the best combo. also I don't know if I would need a pulse fuel pump? or at what degree my timing should be to get the best performance with all the upgraded parts? also I need help hooking up the throttle? do I need extra parts for that? thanks and hope to hear from you guys
