K601 Weber Jetting

Does anyone know what the "baseline" jetting for the K601 Weber? I'm curious how my jetting compares to an out of the box Weber.... Thanks....

idle jets 50/50
main jets 125/120
air jets 160/155
emulsion tubes F50/50

Re: K601 Weber Jetting

The second numbers look pretty close to the out of the box open air filter model. I believe the stock air cleaner adapter model is 105/120. FYI, I never changed the air jets or emulusion tubes just the main jets to 135/170 and it seems to be on the money for a mildly modified 1600.

Re: K601 Weber Jetting

Why do you need to go larger on your idle jets? How is the engine idling for you to come to this conclusion. I'm curious because I'm having no problems with the original size and I've got a 1600.

Re: K601 Weber Jetting

According to everything I've read, if the idle adjustment screw is more than 2 1/2 turns out from bottom to achieve a "best idle", the idle jets are too small and require larger ones.
I've got the Weber on my 1600 as well. The Weber is an older one, myself being the 3rd owner. I believe it was purchased originally by a zooker from Colorado. I'm not sure if he tinkered with it to compensate for the altitude. I periodicaly experience a lean miss at idle. Increasing a size or two might correct this.....

Re: K601 Weber Jetting

crow & GODSZUK--i like crows basic setup-but stock k601
come with 120/155 mains-crow is running larger main on
primary 125/120 and sometimes geting lean- i would switch
crow to 130/150 or 135/160 on mains and leave all else the
same-oldzuki

Re: K601 Weber Jetting

Thanks alot not sure what ould be the best setup. But I am getting a better Idea as this post goes on. I has a 1600 with a mid range cam, header, the performance weber(larger jets), and a high power ignition system. Any suggestions I know you will have to play with them a little but a starting point is always helpful.
