Topic: Stock size for 78 550K Jets??

[retrogrrl]

Anyone got it handy?.. I have looked through the parts manual... and greenspun, and here and... well I looked hard.

The guy I bought my bike from put pod filters on, (I realize why now after wrestling with a stock airbox) and want to know if he has up-jetted.

From previous posts I could find it seems like it's not clear cut whether I will need to up jet or not.  If anyone has exprience with this any help would be great.

Oh, and a big thank you to you all for being a great group of people to talk to!

the slow jet is smaller in size than the one currently in the carb body, although they are threaded and seat the same.

will these work in a cb 500K1 ?
