I consider this a pretty critical part so I did spend a little more on the Made in Japan K&L needles as opposed to the cheaper Chinese ones. Still, only about $5 each, if they work out that's a savings over new $15 to $20 needle and seat assemblies.
I did have some "teething" problems. After a couple days, one carb started leaking. Turned out to be a bad float, not the needle, so that was a good thing. Took a couple of tries to get the new float set right. I used the clear tube method because I didn't want to pull the carb set so I could measure. This whole carb set is a big experiment, lol, XS500 carbs I adapted for 650 use .....
