Howdy all, After putting a weber carb on my 62mph sammi. And that's with the wind at yer back, i am telling you....it's f'in day and night, this buggy will smoke em' in first and second, i'm passing people for the first time ever and i cant tell you how fast she'll go 'caus its faster than i'd ever take her. If your looking to wake your suzy up, this is all you will need. leave the headers and cam at the store.
