Urban warrior CB750 build (It's alive!)
« on: Sep 21, 2010, 23:17:22 »
OK, so when I got the 750, it wasn't exactly a rust bucket or a frame with a box of parts. It actually ran, although kinda choppy. Got her home, went over her, tuned up the usual things and then stepped back. I knew I had a lot to do but didn't know how to do a lot. Joined up on DTT and started asking question after question. As of right now, we're at the "runs good enough for daily driving, but looks like hell stage". Here's a couple quick pics from today. Did a little work over the weekend and today.

Dropped the clip-ons down in between the triple tree mounts, took the primary cover off and polished it up, re-adjusted chain (finally), trued the front wheel (let me tell you how much fun that was...), bled the brakes, adjusted rear brake, and re-routed clutch/throttle/choke/brake/speedo and tach lines for new clip-on placement. If anyone wants some tips on truing up spoke wheels, ask someone else, I don't ever want to relive that fiasco.

Ha! They're not THAT bad! Granted, I don't invite all my friends over for a truing wheels party, but still.....

Can we get an overall pic?

This is what I started with, I know it's not much different now, I don't want to take it apart and do paint and all that until the winter when I wouldn't be riding much anyway. I haven't been able to ride it much this summer, so I'm trying to get all the riding in I can now.

Oh, and about the wheels. It's hard enough trying to figure out which spokes move the wheel which way, but when the hoop has dents in it and the chrome is pitted, causing the dial to jump all over when your trying to get it within .010", yeah, it's THAT bad... Haha!

You and I have the exact same bike..

Have anymore pics of the front?  I'm thinking about running clip ons on the top of the tree as well.

I like that i'm seeing more and more dohc's up here. Yours looks good, I like the seat, i'm gonna guess that its home brew?, if so its even better, i'll be doing homebrew on my 900. Question, how well does it run with the pods, i've heard cv carbs don't really like them(guessing the 750k's came with cv's)

Good to see some more Dohc 750's on here!  I'll be staying tuned to this build for sure.  Oh, and maybe im a glutton for punishment, but I kinda enjoyed truing my sohc 750's wheels.  I dunno why, just seemed fun.

Well done for doing the wheels.  I takes a while to get your brain around it, but as you get the experience it gets easier and faster.

Just for future reference, try not to use a dial gauge next time.  They are enough to drive a man to drink. Besides the rim will always have dings in it and where the ends are butt welded there's typically a huge jog (on aluminum rims at least).  1mm is close enough on rims.

Thanks for the words of encouragement! The carbs ran a bit lean with the pods, the shop said they had to up one of the jets (can't remember which one). but it does run good now, no holes in the acceleration. The clip-ons were up top, but I switched them to the lower position and love 'em. I don't have a pic of the front right this second, but I'll be back at the house Friday and I'll get one then. I'm looking forward to seeing some other 750's up here in the build threads, always up for sharing some cool ideas and tricks.
The seat is a homebrew, but not my home. It came like that when I bought it. A new Carbon Fiber over Fiberglass seat is going on when I get some time to build it. It's not that comfy right now, but it's rideable.
