It's really hard to staff an entire dealership with genuine experts who are also honest enough to say "I don't know" when that is the case and then take the time to look it up. I think the majority of motorcycle buyers have done more research and know more about the bike they are looking at than the salesman they are talking to. I don't put any stock in what dealer personnel tell me and I do my own research. Dig this one. The last time I went into Western Honda in Scottsdale to buy parts I went up front to look at bikes like I always do. I told the salesman I wanted to look at some lower handle bars for my CB1100. The salesman looked over at a new CB11 and told me firmly and confidently, "No lower handle bars can be put on the CB1100. The stock bars were designed to clear the gas tank and as the bike ages the bars will "sag" and the existing clearance will diminish." Good grief. The expression - Never argue with an idiot - comes to mind. I bought new lower bars elsewhere and then did the impossible by installing them. So far, my new bars have not "sagged" and hit the gas tank.

I too have had a similar problem on my bike with my tires sagging at the bottom.
When I took into the dealer to have it checked out he referred me to the section of the owner’s manual addressing the tire inflation procedure. Needless to say when I read this post about handlebars sagging, the preventive maintenance procedure was clear to me. Not specifically mentioned in the owner’s manual it certainly is implied how to handle this issue. I went to Costco and removed one bar end and inflated the bar between 2 – 3 psi. This resulted in a good "Al dente" feel to the bar. I realize this may more be more effort than some want to go to, but personally I feel it’s worth it to prevent having to replace a sagging bar. I will work with Honda America to get an addendum to the owner’s manual to clarify factory recommended procedure and frequency of this maintenance issue. A word of caution, do not over inflate the bar, we’ve all seen the unfortunate results of over inflation of the bars.
Hope this helps.
Oh, don't worry about the tire sagging, it'll take care of itself as the tires wear in.
As the tires wear they lose rubber so that means that they bulge out more because there's less rubber holding the air back, voila ! sagging gone !

Since I believe everything I read on the internet, could you post pictures of the "sagging tire" and the inflation valve for the handle bars?
RE: 10-30 vs 10-40 oil - rboe - 07-20-2013
The handlebar end weights are really pressure relief valves (I suspect they double duty) not unlike the pressure relief valve you see on pressure cookers. If these valves are loosened or lose their calibration handle bar pressure will suffer and the result in sag. Attempts to repressurize or use nitrogen will not be successful unless the pressure relief valve is repaired or attended to.
Adding heated grips can affect the relief valve as the additional heat will cause a pressure spike. While the bars can handle it (if you use factory supplied bars) the relief valves will need a slight adjustment with the seasons.
Honda sells a special tool for this, do not try to adjust them without this tool as it will void the warranty and cause your sperm count to lower. Why this would affect the warranty has never be properly explained to me.

Who would have ever thought? I guess I won't believe everything I read anymore.

My CB1100 had Yamahalube 10w-40 from the dealership at 600 miles, and at 1100 miles I swapped it out with Castrol part synthetic 10w-40 (I wanted to do 10w-30 but it was cheaper to get a jug of 40).
I just swapped it again at 3300 miles (Castrol didn't give me any warm fuzzies and I couldn't wait to hit 4000) with Amsoil 10w-30. So far, having fresh oil in the bike has made it extra smooth, I wanna say maybe even smoother than when I first rode her home. I can't wait to see how well this Amsoil will hold up over the next few thousand miles.

Just ordered HP4 for 1st oil change. We'll see how it does. I've always run manufacturer specific oils on my bikes & outboards.

I really wanted to try that HP4s full synthetic from Honda..think I'll run HP4s next time..

is it the HP4S full synth Fuzzy..? if yes please let us know how it goes..
RE: 10-30 vs 10-40 oil - HikerToo_imp - 07-24-2013
I went with the HP4S full synth 10/30 in mine, hope to get 4K miles out of it between changes.
Since the user manual only had 10/30 listed, that's what I went with, if I had known the service manual also approves 10/40 I probably would have went with that for the summer months, and 10/30 for cooler months.
Then again, the engine is new and tight, so maybe 10/30 IS the best way to go for now, regardless of outside temp?
I chose Full Synthetic thinking the air cooled could run hotter and Full Syn will withstand high temps better.

I'm using 10W-40 with no issues. Aussie manual recommends 10W-30 but also has a graph indicating for hotter temps 10W-40 is fine. It regularly gets to 40 degrees celsius here in summer and I've always run 10W-40 in my inline-4s.

HP4 is a synthetic blend. HP4S full synthetic. To my knowledge the 4S doesn't come in 10w-40 only 10/30. I wanted to try 10/40.
