Why replace serviceable, operational parts (such as cam chain tensioner, balancer and camshaft chains, and low-mileage functioning bearings)? Your bike, your money, your choice. Just wondering!
Mostly because I donít know the actual longevity of the components and donít want to spit the cases again for the next 10 years to replace components. Itíll only get more difficult as I get older.
Then there is the concern that like a chain spoken set which is always replaced as a set to prevent undue wear you replace them as a set. Iím putting in new cams with new adjustable gears so I will replace the cam chain. And guess Iíll buy a new gear for that too so they can all wear as a set.
Balanced assembly though is questionable. Sounds like itís a wider multiple link seriously tough chain that might not even be worn much at all at 14K miles. Got an idea how long they last? If less than 50K miles itís a no brainer for me to replace it. 100K miles or more and Iíll leave it as is.
Same goes for case bearings too. Heck, I found a shop in AZ that will perform an isometric superfine transmission service for half of what CWI does. And I might do that too. Itís a permanent modification that actually improves strength by up to 30%, lowers friction, and makes a smoother shifting transmission. If it lowers the gear noise that would be a significant plus factor for me.
Of course, the big question for me in this thread is gaskets for the bottom end. Iíve done some searching and not much info on the bottom end gasket reputation. Or fit. I suppose I could but the Athena set and spray them with copper sealant from Permatex to make sure they seal well, but theyíd never be reusable like the Cometic gaskets if I had to pull the sides again. Or for that matter easy to remove. Not that I want to ever take it apart again. Just trying to plan ahead in case I do.
