Inner primary replacement.

Well,
after 23,000 miles it looks like my primary is starting to drip after a hard run. I was thinking now may be a good time to put that chromed inner primary on to match my outer primary. Is it something that is easily done in the garage? Any special tools needed?

RE: Inner primary replacement.

You have to pull the clutch and the compensator, both of which have rather thin nuts. I had the faces of two sockets machined down for full contact so nothing gets stripped. Also you need to make something to jam the chain so you can turn the nuts. Good luck.

RE: Inner primary replacement.

You need a couple of huge sockets and a large can of elbow grease. I forget the exact sizes of the compensating sprocket and clutch sprocket nuts, but they're in the neighborhood of one and three eighths inches. The compensator nut is on at about 170 foot pounds and secured by red locktite. It took a friend and me pulling on a long-shafted bar with another friend draped over the bike (to keep from pulling it over) to break it free. You can make a tool to lock the sprockets with a piece of steel from any Sears Hardware. The "how-to's" can be found at Harley Hog's website.
So you can do it with a little planning and some time, and the money you'll save will make it well worth it. Not to mention that you'll gain a little familiarity with your bike.
