I can confirm that the Hif carbs will bolt straight onto that monifold. I have had my rapier lump running on a pair of 38's. I didn't realise until I took it to get set up that I only had limited opening of the butterflies, but people have got round that with the single su's, so easily doable on a twin set up. Makes me wonder how much more power there would be if I had stuck with them and got them fettled. Hmmm....I found the carbs and a spare alloyy manifold the other day......!!!
