well I tried to ride it last night.  didn't event get out of the garage.  Rear tire is flat.  I had a new tube put in when I got the tires mounted and I'm pretty sure they pinched the tube putting it on.  They must have never checked it and I didn't check it till now.   >:( so sad.  it was ready to ride.

I got the tire fixed and have ridden the bike around the block now.  Man, does it feel different.  The suspension feels crazy stiff compared to the old bike.  I might need to play with the shocks some but maybe they're suppose to feel that way.  Brakes are insanely better.  And the bike feels like it has more punch in the low end, probably due to the higher compression.  Headlight is way brighter too.

I noticed a few bad things.  the right front blinker hits the tank when turned all the way (but left doesn't) i'm going to try and move it up or down to hopefully prevent this.  The Center stand brace was loose and moved.  this caused the center stand to clink around and make some noise.  I just moved it back by hand and need to tighten it up. 

I need to do some adjustments on the clutch and controls but overall things felt pretty good.  I'll probably ride over to hondamans house soon and get him to look things over. 

Still waiting on my replacement seat cover.  Final pictures will come after that.

Is anyone interested in any of my spare parts on the super cheap? Basically cover shipping and donate what you choose.

Some items I have are tail light, signals, headlight, ears, seat bar that holds rear signals, shocks, beat up gauges, pitted fork tubes, and other small randoms. Look through my build for details.

Flybox, calj, Eydugstr And Hondaman get first dibs for all their help.

Did you ever get the black seat in? Would be great to see the final look when you get some time.

Still no sign of the seat  :'(

I sure wish it would come in .  I was out on vacation all last week and expected it to be here by the time I got back.

There she be in all her glory.  So satisfied.  I still need to redo the seat cover because the original tabs didn't hold this one on very well but it's good enough for a picture.  I have 32 miles on her and everything seems to run good. 

The overall goal was "just better"  I think I achieved that. I really wish I had more detailed before photos.   Not a Café, not a Brat, just a motorcycle....my CB750.  Mostly stock with some cosmetic upgrades.  All the work was done by me, except the Top End rebuild by Hondaman and he did the custom swing arm bushings.  Everything feels like a modern bike now.

Hi there, I just a had a read of your bike while we're waiting for AintNoEasy to get his running, and noticed you said something about the chain not lining up.
77s have the wide sprocket carrier that offsets it outwards 10mm.
I've put up a photo of the 77 and earlier carriers, and what I have on my 77.
It's either me or you that have the wrong one on, but they look different on mine.

Wider carrier, smaller spacer on outside, longer greasy spacer inside, sprocket closer to swingarm.

Also the  pressed metal chain catcher ring on the outside seems extra important now because there's not enough room for the chain (at least for the 630) in between the sprocket, the sprocket studs and the swingarm if the chain ever comes off, instant lockup. I've had a wheel lockup on a bike,(but not from this,) and am lucky to be alive. I'll leave mine on.

I converted to a 520 chain so it might look different.

Maybe I have the wrong spacer in, I can't find a good photo. different sprocket and chain size wont change the alignment difference.
AintNoEasy has his wheel off, I'll ask him to look at his for me.

Yes, I should add, very nice work on the detail and paint, I realized my first words to you weren't the most positive, Ha. Sorry, I hate when that happens to me, which it has.

I got Icon shocks and springs as well, it felt like a motocrosser, put all my old springs back on with the Icon bodies, I need another 20 kilos to make their springs work. Suppose I should have mentioned my weight when I ordered.

No worries. I'm the same way with the ikons. I don't compress them much but they make a big difference
