Yes, the intake manifold/boot is even smaller. but I thought since XT225 uses 34mm carb, the same size should work. XTNG later replied even though their carb states "34", in real the venturi is 32mm.Did you measure the diameter of the intake port on the head? It doesn't do any good and probably will do harm if the carb is bigger than the intake port. IIRC, the intake port on the TW head is about 30mm.
I'd imagine the intake port on head could be atleast drafted/smoothened to get rid of the sharp edge. I am not saying I will use the honda manifold, rather that it is a possibility. I plan to document as much numbers as I can - even go as far as to calculate real world horsepower curve by knowing weight and acceleration. so we will see. the friend I was mentioning here and there is going little bit different path. he's going to swap only crank and whole top end, doesn't plan any modifications, so his will be a stock 225 with TW's MV28 carb. only thing not stock is his pod air filter, since his TW is quite custom. I will be comparing his and mine.
really? then how is this possible?The only way to get the true wider ratio in the dub is to use Placerlodes shaft extension because 1st gear is part of the counter shaft.
