We compared the Mikuni 165 jet to the dyno jet 170 and the mikuni looked like it had a bigger bore than the dyno, not to mention the tapering of the jets on the mikuni. but 185/180 isnt bad, little rich still but after i drop down a few 1000 feet when i go to the dunes i think ill be in the clear, maybe 180/175 for where i live here. but thanks for the help

PS Anyone know why dyno jets are'nt tapered and mikuni jets are?

 

Quality? Sorry but I'm not a big fan of DJ.
