Replace rocker box gaskets on a twin cam harley?

SOURCE: replace rear rocker box gasket

Replacing the silicone gaskets between the rocker box cover is not that difficult. Simply take the bolts out and lift the cover off, replace the gasket, put the cover back on with the bolts loose and line them up correctly. Then tighten the bolts to about 80 - 100 inch pounds of torque.

If the leak is coming from below the lower rocker plate where it mates with the head, this is a bit more difficult and I'd suggest taking the bike to a repair shop. However, if you'ver mechanically inclined and have the tools, even that is a job that can be done by an amateur mechanic. If this is the case, please ro-post and I'll tell you step by step what you need to do to replace the gaskets beneath the lower rocker plate.

Good Luck

It sounds like you might have some wear in the rocker arm bushings and the shafts. This is a bit unusual for 22K miles but I have heard them have a slight ticking noise before. It's not anything to really worry about unless it really loud. If this is the case, you can pull the rocker plates off and have the bushings replaced. This is not something that I would consider a "user replaceable part". The old bushings must be pressed out, the new ones pressed in, and then reamed to size on the new shafts. This is a job for a properly equipped shop.

Now, to save money, you can pull the rocker plates off and reinstall them yourself. It's not difficult to do, you just need decent torque wrench so that you don't strip a bolt.
