As you know yet, the late Patrick Godet sold me a splendid Grey Flash replica road version identical to one of the three built in 1950 by Vincent. The bike is equipped with the original carburetor AMAL 10TT9 but it is not suitable for easy use on road or rally. According to opinion from AMAL, I could install a 229F /1DV (that of the Comet) and it seems to me a good idea. The performances of the Grey Flash is different and much better than that of the Comet, it would be possible to change elements of the carburetor such as main jet, needles, jet block, throttle valve or others, I don't know what's the best. What do tou think about this kind of carburetor's modifications ?
I thank you for your advices.
