Motorcycle Honda Yamaha Kawasaki Suzuki Review

I didn't actually use a needle as all I needed was a spring and o-rings to rebuild my flexible adjustment needle. The spring and O-rings do their job.

I have krf 450r, when fitted it seems ok, then you start the bike and everything works. That's not quality, that's Chinese junk, don't pass by. Buy an American by paying about $12 extra.

This fits my 2004 Yamaha FZ1. I bought 4 of these for FZ1. It didn't come with a spring so I used a spring from my original lead screw. I ground the tip of the needle to make it sharper. I don't know if it helped, it just didn't look as sharp as the original.

Works after modification. The grip portion of the needle hits the throttle linkage, preventing you from lowering it and opening it the specified number of turns. I wasn't very happy with it, but I've already changed it. Although I can now adapt on the fly.

This mixer screw comes with the wrong washer. Not one wrong, but two! Big fats, I have no idea what app you would be using. Oring was right. Luckily I had an old Honda washing machine from the early 80's lying around because they've been in the same style for so long. Not what I needed but at least the screw worked. I also used a different spring because it was too long.

If you've ever dealt with air/fuel mixture screws on a Honda Shadow dual carb you know what a nuisance they are. Installed them and made setting up carbs as easy as possible. I can adjust them by getting on my bike or running a red light when it's running. Very easy with numbers to make sure you put the same amount. Must have this if you have a two carb Honda Shadow.
