The end is getting closer.  I'm so far behind where I thought I would be at this point I've stopped even worrying about how little progress I've made.  I did make some pretty significant (for my little project) progress this weekend. 

Afer the whole "rear set" issue, I did some running around town, some asking about, and found the most awesome guy Chris that works at a gear manufacturing shop her in Portland.  I'm not talking regular gears, when I walked into the shop to find him there were machines two stories tall making gears 6ft. tall.  I was blown away with the place.  Anyway, he was a referral from a referral and when I found him and explained my situation he was super helpful.  His business card says his title is "mechanical smarty pants".  I knew this was the right guy for the job.  He had a big hydraulic brake of some sort.  He was able to bend an offset in my rear sets with no problem at all, we literally just used a wax pencil, marked some bend spots, set the machine up and whammo!




After the work was done, I asked how much I owed him and he said bring me a case of beer when you get a chance.  Such a nice guy.  It restores my faith in people when you can find folks who take an interest in what you're doing and offer to help.  Sorry to go off on a tangent, but his years of experience and access to the right tools, and 10 minutes of his time made this so much cooler and less kludgy in my mind.  After the month I've had, getting this work out was just one of those little things that let me a breathe a sigh of relief and made this build so much more bad ass.

Anyway sorry for the diatribe.

If I was to go back and do it again, I'd have him bend a tick less of an offset, and pull the rear sets in a little tighter into the swingarm, but it's still pretty badass in my opinion.





So now that the rear sets are settled, I was able to build the rear wheel, and all the mounting bits.  I test fit the pegs, foot controls (which I'm going to have to do some work on), and pretty much have the entire rear done sans shocks.  Soon as I grab the front axel out of storage and mount the front disc It's gonna be ready to roll!




And last shot with all the chain adjusters mounted up etc...


Only last little "damnit" was that the pegs I ordered from Cognito were wrong.  I got 3 front control pegs, and one passenger peg.  I figured I could just use them interchangeably but the shoulder length is different.  But I'm sure we'll get it sorted, and it doesn't really impact me getting work done while I exchange them out.



Also got the gauge bucket coated...

I don't want to rain on your parade, but... with that much offset in the right side peg, you may have interference issues with your exhaust  :-\ Might want to throw that on right quick to check-

The rest of the bike looks really great by the way!  :D

Thought about that, too worn out to test fit before I put it on.  Probably the next thing I'll do before trying to button everything up for good.  Thanks again for the heads up.

Ha!  Another thing I didn't consider.  I gave a sit and it didn't seem too bad.  I rode a buddies TL1000 for awhile and I guess that cured me of caring about getting split like a chicken while riding a bike.  This bike has a huge tank and I didn't really notice.  Hopefully she'll get used to it!

Started in on the carbs.

I'm going to be using pods, or something equivalent, so I figured this would be a good chance to order new mains, and clean everything out.

I was pleasantly surprised which how good the condition of everything was.  Dirty, but nothing too out of place.  The cheapskate in me even thought the gaskets were in good enough shape to reuse ;D  (don't worry I'm ordering new ones)





The only thing I was a bit worried about was the accelerator pump diaphragm.  It's pretty crusty and gummed up on the top.  The actual soft diaphragm material is fine, so I thought I might take a stiff nylon brush and some carb cleaner to it.

Sad news for this build.

Life (divorce), and the need to move are ending this project for me.

I'm looking to sell the rolling chassis and all the parts, bits and bobs that I've accumulated over the last couple years.

If any of you that have followed this thread might be able to pass the word on to anyone looking for a mostly finished project with lots of rad parts, please DM me.

It's the latter, but it involves a co-owned house that's 3/4 of the way through renovation, dog, blah, blah, blah.  So basically a divorce.

Already thinking about the next project when things settle, I get back into the black, and have a space to work.

Thanks for the words of encouragement, and help along the way.  Hopefully, I'll be back soon with another project.

Serious bummer, Mule.  Having been through a split, just keep in mind that "it's just stuff that can be replaced."

Hey guys, brand new to the forum. I know this build has been quite for a while, but I'll be picking the bike up on Sunday and hopefully beginning the last leg of the build.
