You don't even realize it that can cause these to wear out excessively even if they are greased is not setting your clutch arm before you adjust the flower nut and or cable when you initially set up your clutch and you should keep it this way over time you need to make sure that the clutch cam is set in a neutral position then you adjust your cable and your flower nut the neutral position for the clutch cam could be different on each motor it's usually about the same but it really just depends on how they set up these teeth in the factory okay as you can see these are keyed and they press on you can remove them it's kind of difficult but there's really no need to unless it's severely out of alignment if it's only off a few teeth it's no big deal just means you have to compensate for that during adjustment to set your clutch arm up in the neutral position you'll want to note where that is when this cover is off of the air filter cleaner you want this clutch cam to be flat so that when the bar sits on top of it it's as low as possible so right here is our neutral position for the clutch arm if we go further out it'll start to lift the bar if we go further in it'll start to lift the bar.

If you have grease okay so move it into the neutral position and then set your clutch this is also helpful on builds that are tight because you'll have more space before this bar hits things like the down tube or the carburetor okay let's talk about another issue which is clutch slipping now obviously we've already been over the pads if you have contamination on the pads that can definitely cause the clutch to slip however it could just be a poorly adjusted flower
