Works as intended. No issues.

It's genuine Keihin, so you know it's good. I went to a 35 leak jet on my 04 YFZ450 and it really helped the lean bog issue. This is the cheap version of the Quickshot accelerator pump as it increases the pump shot by restricting the leak back of fuel from the circuit. Smaller leak jet, tune accelerator pump timing, and then there's no need for the zip-tie mod. No bog.

Only use authentic Keihin jets for Keihin carbs, the knockoff jets will only leave you wondering why your machine doesn't run right.

Keihin 99101-393 Series Main Jet is a great upgrade for my CRF's BBR Big Bore kit.

much like the keihin pilot jets the only complaint I have is price. Still did the job like it should after a pipe and filter upgrade.
