R90/6 needle clip posiiton.

What is the needle clip position for a '76 R90/6. the Bing manual says #2, but other sources say #1. Thanks.

I'd go with the Bing manual...what are the "other" sources?

probably a dumb question

is the top notch no. 1? Best I remember I am on notch no. 2 on my R90/6, but probably need to spring for new needles.

The owner's manual says notch #1, but Bing says #2 in their manual. when I last renewed some carb parts I tested both positions and #2 is the way to go.

Haynes manual.

Haynes manual.

Not the ultimate source...best to use the Bing settings. Remember, all of the settings recommended...by any source...is just an initial setting. For your setup, altitude, style of riding, etc., you might need to change things.

According to the Bing book, the #1 position is closed to the blunt end...this is the leanest setting for the needle. Remember that the idle circuit is in play from 0-25% throttle, the needle from 15-80% throttle, and the main jet from 60-100% throttle.

Edit: And now to contradict myself, here's a page from a /6 manual...note it says clip postion 1 for the R90/6:

As I said, pick something and see how the bike peforms. The clip position is a relative big change to fuel flow. Jet sizes, etc., would be small changes.

I've got my 74 R90/6 set on 2 per snobum's reccomendation and seems to run well and pull hard
