For those who are not sure about buying that second bike, this can help you decide:

I pay a mechanic a minimum of $100 to have my tires changed ... sometimes more. Thinking about DIY. Looks like I need to buy (a) tire irons, (b) wheel shield, [c] replacement valves, (d) weight kit, and (e) a balancer. Amazon has all this stuff, but I just don't know "what works". Any suggestions? Thanks

The last add ... from eBay .. Tokaido (from Germany) .

A smattering of info, on stuff we'll not see in the US, but is fun to look. First link is official Honda, the next is their Facebook page. Which, surprisingly, they respond to, a lot.

Hi guys,

I was recently reading a thread where someone was talking about the smoothness of the bike (I think it may have been Dave) and he mentioned wanting to sync the throttlebody assembly.

There was a mention that the manual says not to do so. I would agree- for most people there is probably not much of a need if your bike is running well enough to your liking.

That being said- lots of other bikes have this procedure as part of normal maint.

Our bikes use the same throttle body design as many many other Honda bikes- just with different butterfly / bore size- and spacing between the cyl pairs. Example - the CB1000R and CB900F Hornet ( 919 )

Heck- even the Honda scooter uses the same design- so this procedure would be essentially identical once you get into the bike plastics / tank.

I started thinking about it- and was curious as our staggered cam timing should show up on the results.

Additionally- although the TB are synced from the factory, as the engines wears- differences in valve adjustments from cyl to cyl will have an effect on individual cyl readings.

Naturally adjusting all the valves back to equal will even out pulses- but I suppose it depends on how deep into a 'tune-up' a person wants to go.


I started watching youtube videos on guys syncing motorcycle TB and found this modern digital version of the old mercury tubes-

Here is the video of it in use-

I was particularly interested in this last screenshot. Due to the electronic sensors- this tool allows much more visual data info and much finer adjustment resolution.

There is another video of a guy adjusting with a similar, but older and much more basic (inferior) type of tool- and it is cool that you can tell if the engine has a bad valve by watching the readout.

Given I have installed custom cams, and in doing so I had to completely change my shim sizing much further than normal- it will be interesting to see the waveforms in real time.

I also may have slight differences due to my dremeling of my velocity stacks- and will most certainly want to take a look at what is going on if I decide to install the CB1000R 36mm TBs.

There was another guy here who took out the factory mis-timed cam and now is running all even cams.... I would think he could certainly benefit by using this tool to see how the cyls are running in comparison to each other and adjust if needed.

So- being the moto geek that I am- I reached out to the manufacturer, let him know I am interested in this tool, and he was kind enough to off me a discount in return for writing up my impressions and results.

I purchased the unit about an hour ago...it will take a while to arrive, and I'll probably play with using it some time this winter as time allows.

My RF-1200 is almost 5 years old. I've been looking at new lids for the past few months. Maybe I'll wait a few more months for this.

"Shoei extolled the RF-1400’s various new features, with comfort and noise abatement as the central theme."

"The faceshield is claimed to be tighter around the viewport when closed, reducing draft and noise. Shoei has added “shield vortex generators,” a trickle-down bit of technology from its race-ready X-14 helmet."

Interesting story in Ultimate Motorcycling. Plus, I think their choice of bike in the very top photo is cool.

I've always been fascinated with how a constant mesh motorcycle transmission works, with the cogs all meshed with their neighbor on the opposite shaft. It looks like it would bind up immediately when you start turning either shaft. The magic is that only half of the cogs on a given shaft are splined and forced to turn with it. The rest free-wheel.

I had too much time on my hands the other day and decided to make a spreadsheet that calculates the rotational velocity (rpms) of every moving part in the CB1100 powertrain, based on engine rpm. You enter engine rpm and the rear wheel diameter and road speeds for each gear is also given. Since the primary reduction ratio is known, each gear ratio is known, and the final drive (sprockets) ratio is known, everything can be calculated. I also diagramed how the power is transmitted through three different cogs for every gear selected.

Anyway, you may download the attached and play with the numbers to your hearts content. The values entered are for a 2014 model, but changing cell values can make the spreadsheet work for any six speed CB1100. I'd be happy to make one for the 5 speed models if somebody wants a copy.

ultimate genius; I like the 2015 version seat ... and I just added; removing the necessary original foam; 2 cm thick for double special gel (http://www.lolopamanes.es) and elastic visco on top. then granada the original upholstery. the seat has grown in height by 1 cm (well for my 1.83 m height ... and the comfort is another; but really ... I already changed the seat in my previous Africa twin adventure sport 2018 ...

I think that most of us have used the PB Blaster in the spray cans but yesterday I used the PB Blaster Grease on 4 very rusty bolts on a 16 year old hitch on a 2004 CRV.
This morning the nuts came of very easy and sometimes if you use the spray cans it runs a lot. The grease is easy to put on with the brush on the top of the can . I am glad that I found this stuff at Northern Tools.
