20mm Hex Key? Holy Hell!

Ok, so update time. Since it was only -11 today (without windchill), I decided to do some work on the bike. And the weekend is supposed to be around zero too, so should get some shit done!

Today I put on my clip-on handle bars, and the chrome headlight brackets. Very sexy. Ran into a problem though...

When I was putting on the left bar, I had to take off the left fork cap and bung the thing on with a hammer and wood block. Well it's on fine now, but I have no idea how to put the cap back on the fork, as it's pretty hard to compress the spring and turn the cap at the same time. The hex socket in the cap is 20mm, but I looked around town and no one seems to carry a 20mm hex wrench or anything!

I tried fashioning one out of an old hockey stick, and it works for fitting in the socket, but it's still very hard to get it to go in the fork.

I feel like the hugest noob in the world here :p

Hi. I just found this thread.

Dude, how did you install your clip ons?? Did you take the upper triple clamp? or did you take the forks off??

Perhaps it is different in your CB, in mine, I was able to take the top clamp w/o having to get the fork cap off. I did take the air hose off ( my bike has a hose connecting both forks).
Here a few pixes:

The clip on clamps are already on the forks.

I hope the hose can be seen in the last pix. The triple slid off past the caps.

quote:umm I know this sounds stupid but I used a 20mm bolt and threaded a nut all the way down, I put the bolt in fork cap upside down and put a wrench on the nut and tightened it down
Same idea, but use a socket and one of those ratcheting thumb wheels.
The thumb wheel fits the palm of your hand so that you can press down and turn at the same time, once you get the threads started then just keep twisting the thumb wheel like a regular ratchet.
Ha, finally found a picture of the thumb-wheel so' you know what I'm talking about!

I understand, that makes sense, because taking the forks off would be the long haul.

BTW, That Canadian CB750L has the right speedometer, I have the dorky 80mph ( I wonder why??? did the US authorities go crazy?? I do not think Honda decided to install 80mph gauges in the US only...<img src=icon_smile_dead.gif border=0 align=middle> )
here is my speedo ( I am hunting for the right one, either in KPH or MPH, I want to really know what speed I travel at...) and the right kind.
My US version 80mph face.

KPH full speed face

Nice assortment of faces.

This is a european CBF gauge cluster ( on CB750, 900 and 1100 bikes)Later I found out these clusters are known as Mickey mouse clusters.

Gheeto: That explains the 80mph faces. It is kind of ludicrous thinking, but it was implemented.
I am getting a 220KPH speedometer from europe, I bought it for 120.00
I want to see the speed I am going at. It has also the MPH range in smaller numbers. I might get the money back by selling my 80mph cluster.
I will show the pixes when I get it.

Trefmawr> I hear you, sometimes it gets difficult, I used WD40 and the clip on slid onto the fork. Fact is it is done.
Any pictures of the clip on assembly installed?

That bike is looking nice!
