Topic: CB750 K0 what needle position?

[zoo mob]

I'm in the process of rebuilding the carbs on my K0 and was wondering if anyone had any insight into what the best needle position would be with my setup: emgo (supposedly slightly restrictive) air filter, original HM300's with some pretty good holes in the uppers, and 120 main jets. Thanks.

Middle position is where it came,Your pipes are a little less restrictive and your filter a little more,try it in the middle.Bill

Agreed, specs list it in the middle with mixture screw 1 turn out.
