from Honda, where are we supposed to get them?
I've got 1975 CB750F carbs on my K4, and the original needle jets were measurably ovaled.
I installed a Keyster needles and needle jets (middle clip, 1 turn out on airscrew) and the bike was way lean; off idle to 2/3 throttle.
I've since put the OEM needles back in but left the Keyster needle jets. I havent had a chance to ride it yet with OEM needles and Keyster jets, but I have my doubts as the keyster jets have a seat that starts 1.1mm higher up than OEM jets.
The Keyster needles, like everyone says, are not even close.
What to do?
BTW, I tried to order the needle/jets from Bike Bandit 2 days ago. They let me place the order, but sent me an email saying they are discontinued.
I realize they is a guy on Ebay selling them for 3x the actual cost, but I'm not playing his game. What a dick move, BTW if you're on here.
