This is very convenient when it comes to leak jet tuning. Changing leak jets in a FCR carb is a serious chore and you may end up removing your carb 5+ times accessing the leak jet for tuning adjustments. This accessible screw type leak jet is right there. Save countless hours and trips to the dealer for various jets. Pays for itself quickly. Installed on my KTM 250xcf which are factory turds in the jetting dept.
If you have a 4 stroke and it bogs when you whack the throttle this will most likely eliminate the bog for you. You have to set timing on the AP just missing the slide as it goes up and u want the squirt of gas to last between .5 & 1sec.
