Post by gradzz »

What should the stock jetting be on an 80 Liquifire? What position should the needles be in? Thanks.

Thanks JDGuy.

On the needle jet I'm assuming the clip position is #4? Which end of the needle do they start from? Point of needle or the clip end? Thanks

The sled runs up to about 7000 rpm at 3/4, but after that at WOT the sled turns into a turd and drops to about 6500. I want to check the jetting to see if its stock so I have a starting point.

needle position numbers, yes, position No. 4 is the recommended. make sure the small plastic washer/seal is installed directly below the e-ring.
