keihen vs. dyno conversion chart

[buster024]

I searched for a minute or so, but can someone post the dyno/keihen conversion chart?

so, I called Yoshi today to order some new machine screws for my exhaust cap (i stripped mine taking out the quiet core this weekend), and they freakin' charged me .25 a screw. The guy actually took my credit card number for 2 screws. Couldn't believe it. Anyway, I asked him what the factory recommendation was for jetting with their pipes, and they told me to use a 178 Kehein......which I don't see on the chart. So I'll probably stick with a 160.

Keihin mains go up/down in 2.5 unit steps. But they just round the size down or up to keep the size labels in whole numbers.

for example:

162 = 162.5
178 = 177.5

FWIW, in my experience most jetting guidelines provided by pipe manufactues are usually way richer than ideal. I figure they do this to cover themselves: even in a worst case senario you're piston won't melt becuase of the jetting specs they give you....
