No adjustments at 16 or 32 kmiles either? What is your riding style?

The CB650R with a screen looks great for in-city freeways where 75+ mph is the norm. The X will hang in there, but it's getting a bit stretched at that point. I would love a test ride. Is it as quick in the corners as the X?

Rather than start a new thread, I'll tag on this recent fix in this thread.

My steering had developed some resistance especially noticeable when balancing at a slow crawl. It was not quite "notchy" but more like spring loaded when turning away from the center position. Eventually it affected cornering turn-in, too. So, after reading this thread I ordered the All Balls kit and picked a good day to tackle bearing replacement. I removed the bearing cages and inspected the races. There was some light rust in the dry grease residue, but the race surfaces looked good; no scoring. Also, looked like removing the bottom outer race would not be short work. I don't see how people have done that without a special tool. Keeping it simple, I just cleaned the cages, packed fresh grease, and put it back together. After making a few nut adjustments via tapping with a screwdriver, the steering felt right.

On the road it feels like new or maybe better since it's less jittery over sharp bumps. Slow crawl balancing is now enjoyable again. High speed turn-in is now precise. Lessons:
  • Moisture will find its way in to the steering bearings causing light rust which makes a gritty pack of grease in the bearings. This gives steering a lumpy or springy feel.
  • The ball bearings are alright with a little TLC and normal riding.

A gun smith I knew referred to building a milling machine. I understood it to be a precisely flat grinding disk with holder to ensure parallel alignment to a surface.

I know my attempts to sand or file anything by hand result in rounded edges, etc.

I considered home milling the shims, but wasn't sure if non-parallel surfaces would be bad in some way. Good to know it can be done. The aftermarket shims available at my local shop do not come in close intervals, so one shim change can push gap from almost tight to almost loose, overshooting the middle of spec.

Thanks for your details.

To be totally inappropriate for today:

May you live long and prosper.

Nice bike.

If cost is an issue, here are data on my 2014X:
4.5 years of daily commuting:
42500 miles
Bought new for 6500$
Current resale estimate 2650$
Gear est 1000$
Fuel 1700$ a 64 mpg US
Insurance, oil, tires, other gear, tools and parts $5000.
No shop labor.

Total cost of ownership after (if) sold 12000$
Cost per mile (cpm) around 28 US cents at this point. If I consider the avoided fuel cost of my commuter car, cpm drops to 22 cents. Drops further still if I consider deferred cost of a replacement car.

I don't know if there is a new bike that will cost less anywhere. A good used bike has a definite advantage with lower purchase price, but how can you know if it's good?

Some observations and a prediction occurring to me in the interim. Sorry if these are too obvious:

Observation 1: The intended use for a road can be inferred from its design. A reasonable inference is that a rural highway with a 12' wide lane is designed for one 8' wide vehicle with 2' allowance on each side. "Safe" speed limits up to 60 mph are posted for these single vehicles. Curves are banked assuming those speed limits. Many / most of our two-lane, two-way rural highways (so prized by cyclists now) were not designed with cyclists in mind. Asphalt and concrete were upgrades to dirt to accommodate a quickly growing, post WWII, modern society falling in love with cars. Horse-and-buggy days were gone. Farm vehicles were to be merely tolerated. But recreational cycling on these new roads was not even on the horizon. We are now employing these once modern roads for a task beyond their original intent, and that is the root of the problem.

Observation 2: Cyclists have won the right to use the roads such as they are. The car is now ill-favored. Cycling must be accepted and integrated into the existing infrastructure. That presents the challenges we're debating. Roads will not be changed anytime soon. The narrow lanes of the UK testify to that. Our local 50 year old "new" bridge is another testament to stalled modernity.

Prediction: The current rules and practices are not enough to keep cyclists safe. If cyclists' death rates become unbearable, pressure will build to adjust the infrastructure, but it must be low cost. That might be adding a dividing line to create an outside lane dedicated to cycling. Dropping the speed limits significantly would make sense also. Paint and signs are relatively cheap.

Meanwhile, I'm re-thinking my (literal) approach to cyclists. I have been passing cyclists (who are safely hugging the white, outside line) while going nearly full speed. The problem is that if one of them were to suddenly move into my path while I'm passing in his lane, I would probably be found at fault even though the law requires only 3'. The legality of occupying the same lane while passing is ambiguous. This ambiguity is similar to the fact that speeding while passing is illegal even though the law also requires passing to be "expeditious".

FWIW,

Good looking bike in a great setting.

At a full speed difference of 40 mph, how many feet of passing clearance is needed to feel safe as a cyclist? Is my 8 ft rule enough? What does a cyclist expect and appreciate?

How are UK drivers different? Is there really more patiance and respect generally than in the US? I find the US Deep South is much less respectful than the NE with respect to driving.
