I'll let you re thread it when it gets to your place lol gotta trade me your '74 though

Made my upper rear shock mounts today.
Before and after


In the shock

I'm going to weld on both sides of the plug then grind the back half somewhat flush. Made it long so I can get a good bead on it, I'm happy with the way they turned out. One less thing that needs to get done

Some really nice work there. I'm sure you could sell those on the site. I'm curious how will you attach to the frame?

[adventure_prone]

I'd think, with no disrespect to Adv, that most members would require metric threads. Not all lathes will turn them, so I suspect thats exactly why ADV had to use SAE.

Metric wouldn't be an issue. Just limited on the number of metric dies I have to choose from.

1/2-20 is a very strong thread, just will confuse some folks if they attempt to replace the acorns with metrics.

Tews - simple enough to pass the slug end thru the frame mount, then weld from both sides (ADV, your plan?)
yes sir that's it exactly
Turning steel on lathes (or alloy for that matter) makes a really pretty part in my opinion.

Coming along really nicely Adventure! Loving it!

Decided I wanted to do the gulf light blue and orange livery on the bike. So I do a Google search for paint codes and now I'm mad.


the frame on this bike is basically the same in the rear as mine

[adventure_prone]

Suspension slugs installed. Starting to get excited




need to find a wiring diagram so I can start cleaning up the stuff I don't need

[adventure_prone]

Here you go-

Are you planning to run a pipe beyond that header? Might have some tuning issues without some backpressure...

Thanks for the diagram.. I'm looking for one now, my buddy just replaced his stock muffler on on his bmw s1000rr, so I might find a way to slip that on. The issue I'm coming across is the cognito moto Rearsets are perfectly in the way to run exhaust up the side. It'll have a muffler on it before I ride it

[adventure_prone]

The problem is the Mac header; it exits the the collector without redirecting the pipe to a muffler outboard of the frame. Differing years of 550s had different brake pedals for that reason. The MotoGP header and exhaust has a very subtle "S" from underneath to aide in clearing the frame for that reason. Still might have the occasionally conflict, unless you raise the rearsets too.

Might see if an exhaust shop can bend you up a small offset pipe and that has the transition from pipe to BMW slip-in welded on too. Could even bend it up a tad too if you prefer.

Or, since you weld, you can buy from here the components and cut and weld them to your hearts desire.

Yup I hate this mac header. But I'll just make it work for now, I might be able to cut off the muffler of the back half of the mac and rotate it to get me a little closer to the area I want

[adventure_prone]

Welded up the battery tray
I don't like the look of it at all. I think it kills the lines of the bike but I'm not sure what I can do about it, the electronics have to go somewhere sadly haha




question for people using electronic tray. What are you using/doing to make sure your stuff isn't hitting each other and shorting stuff out?

Side note, I was messing around with exhaust placement I'd love to do something like this but I just don't have the room to do it lol look awesome though!

[adventure_prone]

Redoing the electronics tray all together. I'm going to build a box that fills the entire upper triangle. Then splitting the box into to compartments upper half for electronics and lower half for storage

[adventure_prone]

I hate wiring so much...

[adventure_prone]

I found this which I think I'm going to start copying tomorrow



This SHOULD be the bare minimums to run

[Tews19]

Cal that looks like a piece of art! I'm sure you could start producing that set up and members would start buying them. Is the moto part itself pricey? 

[SOHC4 Cafe Racer Fan]

Cal,

Have you figured out how to program the indicators to flash X number of times and then cancel? 

I was also wondering about the following:  "the m-Button digitally processes signals and transmits them to the m-Unit V.2 over a thin cable." (from Motogadget)

I took this to mean that everything wired to the m-Button and then a single fiber optic/digital cable connected the m-Button to the m-Unit -- thereby eliminating all but a couple of wires to the m-Unit.  This would not appear to be the case.  Can you shed some light on this?

Thanks,
Don

[adventure_prone]

No problem, I wouldn't mind a set like that myself but I can't justify the price, hell of alot cleaner but I don't know if it's worth that much too me

[adventure_prone]

Little more progress. Figured the brake light out. For some reason dcc has the tail light set up as
Yellow=ground
Black=running light
Red=brake light
 
I was just assuming black would be ground lol

[adventure_prone]

I know Hondas is green. But I expected an universal aftermarket tail light to be a normal ground color lol

Sadly today I noticed my steering is pretty notchy. I'd explain it as wanting to detent to center. So I think a taper bearing set up is in store for me

[adventure_prone]

Having alot of starting issues. Most of the time the bike won't electric start sometimes it'll kick start. Spark is intermittent. Wiring is a disaster. Bout to light it on fire
