I'm getting ready to replace the cam cover gasket on my 2013 R3R (same oil leak issue at the front right that many of you have mentioned). I have a service manual and new gasket and bolt seals. The service manual also mentions replacing the spark plug tower seal, but when I attempt to find a plug tower seal in the Triumph parts catalog, it lists one for some other Triumphs but not for the R3R. Also, are there any other parts I need to have on hand before I start this project? (I have about 7,300 miles on the bike, and I'm not planning to adjust the valves at this point.) Thanks!
