Progress Without Progress

I wasn't able to go into the shop this weekend and make progress on assembling the bike, but I was still able to get a few things done this week.

On Wednesday I ordered the new tail section for the bike.  I also ordered the new tail light which includes a bracket for the license plate.  Here is a link to the tail section which I ordered:


On Thursday I had a chance to meet with the guy I'd like to paint the bike when I am done mocking up the remainder of the parts.  Here is a link to some of his work on other bikes (click on "work" after following the link):


The work on his website is detailed and complicated, but the scheme for my bike will be much more simple.  Still, it is necessary to have a skilled painter who can make the color consistent when working with a combination of the metal (the gas tank), plastic (the side covers) and fiber glass (the new tail section).  I saw some of his work in person when I visited his shop and it looks incredible.

I'm excited to see this bike come together.  The next step (after finishing the handlebars) will be figuring out how to upholster the seat.

So Close to Finishing the Handlebars (I Think)

A situation at work prevented me from working on the Cafe Project last week, but I was back in the shop this week to try and make some progress on the handlebars.  The weather was very nice in the morning so I took the opportunity to ride my CB750 down to Flying Tiger.  Unfortunately, the weather didn't last and I found myself keeping one eye on the clouds.  My work was cut short, but at least I made it home dry, which is more than I can say for most of the St. Patrick's Day Parade attendees.

The first thing I did this week was work on putting the grip on the left handlebar.  The grip is made to cover the end of the handlebar, but I have bar-end mirrors, so I needed to remove a portion of the grip.  Flying Tiger explained that the easiest way to do this was to put the grip on the handlebar and then gently tap the end of the handlebar with a hammer.


The end of the handlebar is sharp enough that after a few gentle taps the portion of the grip covering the handlebar starts to be cut away.


When you get done you have a hole which exactly matches the diameter of the handlebar, allowing you to attach the bar-end mirror.


I then attached the left hand controls.


There was a little bit of trouble getting the mirror on at first because part of the attachment mechanism which is supposed to slide was sticking, but eventually a little oil loosened it and the mirror attached quickly at that point.  I was initially nervous that the mirrors would stick out too far and make the handlebars seem overextended, but I am happy with the streamlined look and I'm impressed with how much visibility the mirrors give in light of their small size.  The visibility is accomplished because the mirrors are slightly convex.




When I first looked at the right hand lever, it seemed like we would have to re-run the brake line in order to fit the lever to the new lower handlebar.  However there is a joint going from the brake line to the brake fluid reservoir (covered by a rubber boot in the photo below) which can be rotated when loosened such that the brake line angles down instead of up after coming up through the triple tree.  One of the mechanics at the shop helped me loosen the joint, reverse it, tighten the joint, then re-attach the right lever, keeping plenty of rags wrapped around the area to absorb any brake fluid that leaked.  We quickly checked it to make sure it wasn't leaking brake fluid after the adjustment and that it still operated the front brake.  Everything looks safe, so the lever is now in place.  




Next week I'll need to re-build the throttle housing and attach the right mirror, then the handlebars will be complete and it will be time to move on to a different part of the bike.

I have picked out the new tail section and will order it in the next few days.  The new tail section will necessitate a new tail light and a new bracket for holding the license plate.  While not necessary, I may also attach smaller LED blinkers to keep the bike as streamlined as possible.  Lastly, I contacted the company I would like to have paint the bike requesting a consultation.  I'll keep the updates coming as the progress continues.

Changing Out the Handlebars - Part Whatever

When I started this blog, I had a feeling that making changes to this bike would take longer than anticipated.  The past two weeks of work have exemplified how a person with little knowledge and no experience can greatly underestimate the amount of time that is required to learn and perform simple customization tasks.  It has taken me hours of work over a period of weeks to accomplish what a professional can do in a matter of hours.  On the bright side, at least I'm learning how it is done and I have the safety net of a professional looking over my shoulder the whole time.

It has been a while since my last entry.  I spent two weekends in Australia and then a week back in St. Louis without a computer, and then another week working out some technical issues.  So now I have a lot of progress to cover in this entry.

Firstly, I ordered the new grips and mirrors and they arrived before I left for Australia.  I decided to go with bar-end mirrors which stick out from the ends of the grips in order to give the bike a more streamlined appearance.


Of course with new grips and mirrors going on, that meant that the old mirrors and grips had to come off.  Taking off the old mirrors was pretty simple.  They are just screwed into the break and clutch levers.


Getting the old grip off of the throttle was pretty simple too because there was no need to save the old grip.  So I took a razor blade and carefully cut the old grip away from the throttle.


Upon removing the old grip from the throttle, we realized that the grips which were on the bike when I purchased it were probably not the stock grips.  It looked like someone had changed the grips at some point and damaged the throttle in the process.  Fortunately, the throttle was still in good enough condition to continue using it.  Unfortunately, we also found another problem: the new grips were too short for the throttle. 


So we cut the throttle down to size and I used the shop's wheel to smooth out any rough edges after making the cut.


Then came the incredibly long process of opening up the holes we had drilled to run the electrical wires through the handlebars.  The holes needed to be bigger, but they need to be more of an oval shape with the oval running lengthwise along the bar.  Shaping the holes required use of a Dremel Rotary Tool (I'm pretty sure that name is trademarked so I'm just going to go ahead and recognize that now).


I'll be honest - all of my past experience with a Dremel Rotary Tool has been watching ads for it on TV.  The ads do a very good job of making it seem extremely easy and quick to use the tool, but it actually takes a little bit of practice.  I had 4 holes that had to be reshaped, and they took hours to get right.  And then I had to check them against the bike, and grind some more, and then check again, and drill some more, and check again, and grind some more.

It was during this process that I came to a calming realization: when this bike is done it will not look perfect.  It will look very good, and I think the imperfections will be difficult to notice, but there will be imperfections, if for no other reason than the fact that I must have scratched the chrome on the handlebars 5 times while reshaping those holes.  While I want the bike to look good, I think I will also cherish the imperfections.  I will cherish them because I put them there, and I put them there because I did the work.  Every imperfection will be a reminder of what I learned and the obstacles which were overcome to complete the project.  And that individualized imperfection has a value that goes beyond sterile perfection.

After the holes in the handlebars were complete it was time to run the electrical wires through the handlebars from the hand controls back to the triple tree.  There are several wires coming from each hand control, so they need to be wrapped with a stiff wire and taped together.


You then spray some lubricant into the interior of the handlebar and thread the stiff wire as a guide for the others.  Then you work the wires through the handlebar until the hand controls are in place.


After running the wires through both ends of the handlebars I was able to mount them back onto the bike.



The next step in the handlebar process is to rebuild the hand controls.  This will be relatively simple on the left side.  It should just be a matter of putting the clamp back on the handlebar and attaching the new grip and mirror.  The right side presents more of a challenge.  If there is anything I have learned through this process it is that if you think you're changing one little thing on a motorcycle you're actually making a whole bunch of changes of varying difficulty.  Such is the case with the right side of the handlebars.  The right lever controls the front break and the line for the break comes up through the triple tree.  That line has to run differently in order to attach to the new handlebars, but that is a story for another week.

Rebuilding the hand controls was just beyond my expertise level and I was running low on time, so I put that project aside for later.  Instead I decided to go after some of the surface rust on the chrome parts of the bike.  I knew that steel wool would help, but I had no idea that it would work magic.  The tailpipe offers a good illustration.  Here is how it looked before I touched it.


Here is after I had done a little bit of work.



By the time I was done I done it looked like this.




So I also did the front fender, front rim and front forks and they all look much better.  I'll finish a few other portions of the bike later.

That is all I was able to get done since my last posting but there is plenty to do next week.  I'll update as the progress continues.
