My Junkpile Bobber build - CB 750
« on: January 17, 2013, 07:02:19 PM »
Hiya all, new guy here....been lurking of the forums for about a month now - Let me fill you in on my build. For quite some time I've been looking around for a suitable older bike to build a bobber out of.  About a month and a half ago I stumbled across a treasure trove of CB 750 bones.
     Not really knowing much about the history of these bikes, I came here and did some reading and looked at the bobbers and cafes all over the internet.
     Needless to say, I fell in love, and bought the whole pile. I ended up with 3 frames, one fuel tank, 4 engines one of which is a hondamatic, at least 6 wheels, various and sundry odds and ends - enough to build one bike pretty much and perhaps another with some parts scrounging.
    2 of the engines are seized, one is a runner and I havent tried to turn the hondamatic over yet, so im not sure on it.

Here is the day I brought em home..



And after a couple of hours disassembling and sorting parts...



more in a bit...

So, the idea behind my project is to build a mechanically sound, decent handling, reasonably comfortable (for a bobber) bike that is ugly in all the right places but has it where it counts...with existing parts and only buying what I absolutely must. I'm shooting for a Wrenchmonkees or bratstyle kind of effect.  I'm shying away a bit from going full cafe, because I want a bit more comfort and practicality. Id like to keep at least stock quality ride and handling, if not improve it some. Im in my 40's and want to be able to ride it reasonable distances without having to bathe in icy hot when I get home.  However, I still want to look like I have SOME youth left in me..... a moderate approach is called for.

Anyway, heres some more pics -

Bad picture but damn what a mess



Stripped down and wiring removed, to see what we're dealing with...



Baby its cold outside! Carb cleaning on the wife's kitchen table, effective, but didn't really go over.



Bought this little beauty thinking that I would use it, but I think Ill save it for a future hardtail/bobber- Looks great but wont have the range I want



Wiring back in, installed some flat bars, tank all cleaned up (C.L.R bath on the inside) carbs cleaned and rebuilt, fuel petcock leak fixed



Test fit... Fat Guy on a little bike...



This is where we might start getting into trouble with the purists...but here goes...keep in mind this bike came out of the tall tall weeds, the tank was full of rust, the paint faded to a weird pink color, I'm RESCUING not destroying :)

Tank stripped and artfully modified -



Rear end clipped, Pipes clipped, initial seat design installed  - no the pipes were not mint condition priceless heirlooms--- they were all 4 rusted through, crumbly, swiss cheese.  I picked this bike on purpose



And here we are up to date - front caliper rebuilt, master cylinder cleaned and working, forks cleaned and new fork seals installed, new clutch cable installed, nice crisp clutch actuator from one of the other motors installed, headlight back in



Just got my vinyl and scrim this week, so this weekend im going to try my hand at sewing a seat cover...and so it goes
