Lurching in gear, no neutral at a stop, a bite point that moves with heat. Three federal recalls cover this on 2015 to 2018 Road Glides, so check the VIN first.

What the light means, how to read Road Glide codes, why a fault alert can show no codes, what reduced power mode really is, and the two recalls to rule out first.

Silence, one click, or cranking that never fires each point at a different system on a Road Glide. Work the three branches in order, and check the 2024 wiring recall first.

Road Glide faults by system, the ten federal recall campaigns covering Road Glide model codes, and what 104 owner complaints actually say. Start with the VIN check.

There is no single motorcycle oil change procedure. Three things about your machine decide what the job is, and this page works through them and routes you to the right one.

Containing it, keeping everything else out of it, draining the filter, and finding somewhere that will take it. Built on the EPA guidance, quoted directly.

The honest case for and against pulling oil out through the dipstick tube, including the one figure we refuse to give you because nobody has published it.

The bottle carries a class and an oil code, and JALOS publishes every filed oil free. A five-step check you can run, and where a maker spec runs out.

The sealing washer is a consumable, and reusing it is how a routine oil change becomes a case repair. What to do when the threads have already gone.

SAE J300 classifies engine oils in rheological terms only. What the two halves of 20W-50 are measured against, and what the free JASO register shows.

There are two oil filter architectures and they are different jobs. A spin on is a sealed steel can with its own rubber gasket that threads onto the engine and is thrown away whole. A cartridge is a paper element that drops into a housing on the engine, and the housing, the cover, the spring and the O rings all stay with the bike. Which one you have decides what you handle, what you can accidentally leave behind, and where the leak comes from afterwards. Difficulty Time DIY c

The conventional oil change, step by step, and the one part nobody can answer for you: whether your bike is checked on the stand or upright, hot or cold, running or stopped.

It turns on your machine, not the brand. What API actually says about Resource Conserving, what JALOS separately warns about, and how to check a bottle.

Some machines do not have one body of oil, they have three. The engine crankcase, the primary chaincase and the transmission are separate cavities, each with its own drain, its own fill point and its own fluid. Harley-Davidson documents that arrangement on its own product page for its transmission and primary chaincase lubricant, where it states plainly that the fluid is not for use in the crankcase as a motor oil. Whether your machine is built this way, and what goes in each

Warm oil drains fast and takes suspended material with it. Hot oil burns, and it sets a drain plug into aluminium that is about to shrink around it.

On a dry sump motorcycle the working oil supply does not live in the bottom of the engine. It lives in a separate tank. A feed pump sends it to the engine and a scavenge pump pulls it back out of the crankcase and returns it to the tank. The consequence for an oil change is that there can be more than one place to drain, and the order matters. Which points your machine has, and the order to use them in, is a per model fact from its own manual. Difficulty Time DIY cost Tools S

JASO T903:2023 sets four oil classes, MA, MA1, MA2 and MB. What each means, how the code on a bottle is built, and how to check the free JALOS register.

Test it in two halves: does the coil energise, and do the contacts actually pass current. A relay that clicks has a working coil and may still have burnt contacts.

Four settings solve most motorcycle electrical faults, plus voltage drop testing, which finds the connection faults that resistance testing declares healthy.

Three tests, all done at the connector with the stator still in the engine. Continuity to the engine case is the decisive one and needs no model-specific figures.
