From my searches it seems that the fcr 39 with the removable intake (or is it exhaust side) is best. You can pick one up for about 350-400 used from what I've found. Will the fcr 39 without the removable intake work???...from what I've read it's a pain in the ass but possible. But i've found those carbs for $200. Is it worth it. Also any opinions on the FCR 37 or 40. I'd imagine all are an improvement over the stock 36mm carb. I've found the FCR 37 for $150. They all seem to have the same/similar body will the 37 work?
