my V1 stock carb has 2 restrictors . i have been porting/tuneing my stock v1 running right on the very edge .i have both restrictors out of the carb cover .
i use the duct tape to regulate the airflow so i can tune on the fly. it works great. it would be cool to make a dics with different size holes so you could dial in your air intake.
guess i could up grade the carb
just need more jets to play with now
