my friend bought some parts for me of his card. I had to longgate the holes to fit the flying horse carb. then I put the air filter on, what a BIG difference. know on my way home metro clocked me 29 mph stopped me. any faster i well get a free trip to dmv. i havent put the performance plug wire on yet. what will it do, when i put it on. even a bigger smile on my face. thanks sick bike awsome fliter
