With the whole regard to the bigger and smaller throttle cable thing, an Idea i was thinking is maybe have a recessed hole on the underside that you have an adapter sit in with the original hole size being the big bore then the bolt in adapter being the small bore? Don't know if that helps but just a thoughtWe are so busy on the header pipes all the spare money is taken up. We are in the process of making the new one as the one we made was not 100% right. Im still trying to figure out the best way to make the throttle cable bracket work the best
