INJECTOR CARE: MR. KNOW-IT-ALL

HECTOR THE INJECTOR

Dear Mr. Know-It-All,
I’m doing a top end on my 2021 KTM 300XCW and was wondering if I have to remove the injectors from the cylinder to slide the cylinder off?

Removal of the injectors is not necessary to remove the cylinder. Just unplug them, noting which plug goes to which injector. But if you plan to do any serious cleaning on the cylinder, glazing requiring a hone, or any carbon build up on the power valve, I’d recommend removing them. You don’t want to infect them with debris since they are located in the transfer ports where detritus can easily navigate to.
