I'm asking this question because a 148 keihein hasn't the same larger than a 148 mukuni or a 148 Dynojet?

thanks

That's wrong because the dyno jet is bigger than the keihen jets.:confused:

[Buffalo400]

The dynojet is BIGGER than keihein in this table, like you said. a 138 dj = 150 keihein (same size).. (the hole of main is for both 0.0580)

an example
a 150 dj = 0.064 (hole of jet)
a 150 kehein = 0.058 (hole of jet)

I found this table on the web.. I want to know is it good? I think yes but I want to know your opinion!:)

I don't think that it is correct, at least for the mikuni part. After I first bought my quad I went to my stealership and told them I needed a 155 main. They didn't know what brand of main jet the carb took, so they sent me on my way with a 155 mikuni. Once I got the carb apart, I was very upset to find that a 155 mikuni was much, much smaller than a 148 keihin jet.
