Another suggestion was to make an adapter/riser plate to lift the rearsets up.  Not sure how I would be able to make it not flex though.

Issue potential with that is the position of the rear set may then be too high to be comfortable for a long-legged Salty Dog like you  ;)

True, but this isn't my bike.  My daughter is only 5'6".  I could live with it for some test runs and a Dragon trip  ;)

Took some measurements and to push the rearsets out enough to clear the exhaust I am looking at 2".  I think a custom bracket is going to have to be made, but just holding things in place it will be super close to not having enough clearance for the swing to move without hitting the bolt that hold the peg to the bracket.  I am not the first person to need this. I found this pic.  If you look just aft of the foot peg there is a bracket like what I need.


Now onto the starting ussue.  Pulled the starter motor out of the bike and hooked it up to the wife's car.  I don't think it is good.  It spins, but sounds horrible.

I found a very nice write up on a starter motor rebuild so I ordered a kit this morning and am going to have a go at it.

I received a good suggestion from someone on the DTT forum for my rearset issue.  It might be the easiest solution, but I will have to play around with it.  The only issue I could see is the heel of my boots touching the exhaust.  Figuring out and routing a new piece of pipe might take some work to get around the brake and shift linkage rods and figuring out how to support the exhaust, but could probably be doable.  I could also get the pipe bent locally.

Harsh,
Do you know if that bike uses the same starter as the 750 & 550/500 use?  If so and your rebuild doesn't work, shoot me a PM.  I have an extra working starter and you're welcome to it.

Ron...thank you for the generous offer.  I haven't looked to see what other starters would work.  If my rebuild doesn't work and if one of yours will work I will give you a holler.


Picked up some flexible pipe on the way home to help with mockup purposes.  Routing the exhaust over the top of the pegs won't work.  In order to clear the shift and brake linkages the exhaust would be sitting right on my ankle.

I may have figured out a way to mount the rearsets.  I just have to see if I can get the part made by a buddy.  The stock exhaust uses a triangle piece to attach it to the passenger peg bracket.  The passenger peg bracket is what I am using to mount the rearsets.  Dug my triangle pieces out of the extra parts pile, bolted them on, then bolted the rearsets to them.  Well what do you know...they work.  They are pretty thin so they flex too much.

Well crap...the seller of the starter rebuild kit just cancelled my order.  No reason given.  However, they still list one for sale on ebay.  I sent them an email inquiring why, but with some sloothing I was able to find their phone number so if I don't get a reply soon I am going to give them a call.

A new rebuild kit is on order so I took the starter apart and got everything cleaned.  There wasn't a single drop of grease in the gears.  There was only one o-ring and one extremely dried out gasket.  So not sure where the new ones are supposed to go.

Is it the same one on amazon for $13 ? 
4 into 1 may have it...
Did you check out Opfar's site and his starter rebuild? There are a few contact points between the body and the cap.  The round plate shown in your photo may show some contact deterioration with a bit of rough metal from a high resistance point.  It may not be a major issue but it can add a bit of positive connection rather than relying on a small contact area. The modification would not harm anything.

Hope you get some answers to your questions and an explanation.

David

P.S. the body can be polished and then clearcoated if you wish to go that route...."pimping her ride". :)  :D

P.P.S.  When is your Dragon trip?

The one I found was on Amazon for $15.  It could be the same one though.  The packaging on just about all of the rebuild kits is the same.

I have no idea what Opfar's site is, but I will be googling it as soon as I finish this post.

I painted it when I did the engine so no need to re-do that.  The CRC Lectra-Motive cleaner doesn't harm the paint.

I will be at the Dragon June 4-11.

Harsh,
PM me your address and I'll drop a starter in the mail for you.  If it fits, you can use it.  If not, well...buy a bigger bike for your next build and use it for that! :)

Ron, wow what a very generous offer.  I might take you up on it, but the starter rebuild kit I ordered shows that it has arrived in my city.  However, it isn't scheduled for delivery until Monday.  I guess I will just have to break out the wood working tools and build a sofa table for my daughter today.  If the rebuild doesn't work I will definitely give you a holler.

I have been toying with the idea of putting something on the back of the shocks along the lines of a manufacturer logo.  Every time I look at the remote reservoirs they are just so plain looking.  Not sure what to do though.  I have thought about my initials, but that is about it.  The coloring would match the green of the paint and the white background would be clear to allow the aluminum reservoir body to show through.




The new spacer and washer for the rear wheel arrived today.  The spacer was a very snug fit both going onto the sprocket and onto the hub.  There is no more slop in the sprocket.

Expand your perspective Steve, maybe come up with name for your design/build company of custom and restorations. SRH Designs or SRH Customs being obvious with no imagination.
maybe a logo incorporating nods to your Navy past with key elements of stuff ypu do, if it is woodworking and bikes, then elements or hints to those in the logo.

Hope it works as designed...frustrating when things show up as defective/broken/bent after you put time, money, parts in them.  Guess that is why it is recommended to get the bike riding then teardown for cosmetic or engine work after you get an idea of what it needs.

Stuck clutches are frustrating things to deal with when a bike has sat...sometimes it can be broken free and sometimes it is signs of problems.

The old style sliding lever in the throttle tube can be a real pain to get working smoothly againif something is warped/bent/ twisted, etc...  can be a pain to get it operating smoothly without replacing parts.  So, sometimes progress in the form of a new model is in a forward direction...othertimes...it is a step backwards.  Cb550 cam cover for 74-76 was a step back because cb500 had rocker shafts that were not free to spin like the early 550.
Other examples are out there for cars and motorcycles of many designs and makes.
Some stuff like starters doesn't require updates as there are easily perfectly fine and do the job easily.
CX 500 bikes started with a stator and chain tensioner and ignition system that proved to be problematic in the bike.  The tensioner problem became known by owners and the ignition system ended up replaced by a TI system...tensioners breaking became a checklist item and was bumped up on the inspection list by owners and service shops be they dealer or other shops.

So, how is the tank design coming along and that paint work?

Hoping for the best on the starter test.

Btw, i will pull up the link to opfar's page he did some mods on the starter to make it more effective on the cx650 as they often have starter issues because the beasts are more power hungry than the cx500 motor.
The plate holding brushes has three contact points for the plate to the end cap...when they build resistance from time, carbon, etc thhis needs a little tlc

There is an amazon seller who sells the kit for $13, another sohc4 er shaded the link... i have it in my bookmarks on my pc, not this tablet.

I am hoping for the best as well.  The splined end was very difficult to turn by hand, but I attributed that to the gear end being packed with new grease.  The main thing that has me a bit worried is in the video I posted there didn't appear to be a lot of torque.  There could be, but it didn't really look like it.

Tank design is complete and the parts are at the painter right now.  They are working on the tank first so they can get it back to me so I can do my part with the graphics then give it back to them to complete.

I did a search for opfar, but didn't really find anything.  I took some steel wool to the plate end and end cap to clean them up so they would have a good contact point.

Well the starter rebuild seems to have worked.  The bike turns over like it is trying to start.  Now to figure out why the left carb drips from the overflow tube.  I hope the brass stand pipe doesn't have a hairline crack in it.

AND SHE STARTS AND RUNS!!!!

It only took about 5 seconds of cranking and she turned over and ran without any input from the throttle.  The idle is high and the choke didn't have any effect, but she runs and all of that can be adjusted.

Figured out why the left carb is leaking out of the overflow tube.   There is a tiny hole in the stand off pipe.  The hole is so small I can't even see it even with a magnifying glass.  I had to blow red food coloring through the rubber overflow tube to even see where it was.

I had a teeny tiny crack in one pipe on my '77 550. I ended up sealing it with JB Weld. That took care of the problem, but I didn't hold on to the bike long enough to see if it is a good long-term solution.

You could probably solder it up without much difficulty too.

I ended up soldering the tube.  It held water overnight so I am calling it a win.

Unfortunately, the fight continues. 
I printed and cut out the tank logos, but when I went to apply them to the tank I had bits of white around the edges and it looked like crap.  Printed two more sets and cut them out.  While they weren't as bad as the first set they still looked like crap.  I think I am going to have to call a buddy that owns a decal shop locally and see if he can print them on vinyl for me.  They will be thicker which will leave a raised bump at the edges once they are clear coated over, but I really don't have much of a choice other than having them painted on.  Which at this point, since the tank is already painted, might prove to be a bit difficult and would certainly cost me a chuck more money.  I really need to get them on today so I can get the tank back to my painter because he is going out of town on Thursday.


A little teaser pic.  It turned out a touch darker than I wanted, but I think it still looks pretty good.




Met with my buddy after work and he made me some vinyl decals.  I managed to get them on the tank and pretty damn even.  Since I couldn't get the tank to the painter before they closed for the day so I am going to have the wife take the tank to the painter tomorrow morning so he can clear coat it.
