RE: The OBSERVED Valve Clearance thread - MM300_imp - 11-29-2016
I just got my 2014 DLX back from the dealership / 8000 mile service.
8079 actual miles.
No adjustment needed or done.

I don't see anything getting tight so I'll probably go another 36,000 miles before I check them again.

As you can see I have a 3 valves with border line clearances on the loose side.
I'm debating the need to adjust and might just check again after the summer...
Am I being lazy or do you agree?

My only experience with adjusting valve clearances is with 1960s era Hondas. I found that valve clearances tended to tighten-up over time with the stem/nut adjustments, especially on the exhaust side.
That said, I have no idea if this is the case with modern day Hondas like our CB1100s. Can any one comment on on this?

I think there’s more room for making a critical sequence mistake, or damaging a part, or contaminating with dirt or a metal shaving whenever you do the high-skilled cam removal to adjust a shim that’s marginally out of clearance.
And nobody can set the motor better to spec than the builder at the factory in Japan. Especially if it’s your 1st time doing it on the CB1100. Which is also usually the case at a Honda dealer because they sell so few CB1100’s.
Change your oil often and don’t over rev it or over-heat it is the best way to maintain your valve clearance from the factory.

While I agree with the possibility of dirt, leak, improper tq spec, etc- the timing is easy enough. A tooth is a tooth, timing marks line up...
That being said, if someone has never timed an engine- and isn’t fully comfortable ahead of time, go start on a single cyl bike.

If they are on the loose side, for exhaust valves, that's actually not such a bad thing. You could probably go another 4,000 miles and check/adjust at that time. They will run cooler. The valve seats are of excellent quality as are the valves.
Your call, boss.
