Another newbie with a project
« on: May 20, 2011, 07:30:49 PM »
Hello all,
  I found these forums about a week ago, lots of great info!
This '72 CB750 was a gift about 15 years ago from a now passed on Friend, and has sat in sheds, hedges and garages ever since.
 She's now been reduced to a pile of parts.  Never having done this before I'm working towards as close to an original restoration as possible, with a few personal touches of course.  Still have the side panels, will keep the orange. Havn't decided on exhaust yet, most likely 4 into 2, bought an air filter box, but considering pods, will tear apart that engine and decide then on a big bore.  CB850...why not? There must be posts on that topic I havnt read yet.  Thats a long way off tho, I've got tonnes of questions, but one thing at a time and this weekend the rear bearings are coming out.
  Thanks to all in the old posts, the wealth of info is great!
Its all about the journey.

Ok, I dont have a blind bearing puller, but I've read a lot of posts on bearing removal and thought how hard can this be?
Ha! Looks like I'll be dropping the hubs of at a shop. :P

Welcome OC.  Good thing to bring your friends's bike back to life. Looks like you have your work cut out though but you've found the right place for any answer...Larry

  Slowly making some progress.  The bearing removal was a roadblock, I could not get any of the methods posted to work, or bring myself to drop the hubs off at a shop and pay a premium for minimum shop time for something I should easily be able to do myself with the right tool.  I figured I knew enough mechanical contractors one was bound to have a blind bearing puller, but no luck.  Until a couple of fan mechanic brothers tack welded a nut to the bearings, popped them out, AND supplied new bearings "thanks guys".
So was left with this, just a few deep scratches:



After some wet sanding and polishing:



The rest of the rear hub:



  The middle ridges I just cleaned up the best I could, so porous I cant see myself wet sanding them out. I also didnt spend a lot of time on the sprocket, I figure its mostly hidden, will get covered in grease, and after some clicks will get replaced anyway. The photo dosnt do the sprocket cover justice.
  The new brake shoe install went real smooth, not tapered like the originals, but mechanic tells me thats no problem, they fit and rotate great.
  The original rims are scratched from what looks like a do it yourself rubber replacement, so will try to unload them and the original spokes nice and cheap on ebay.  Have the new ss rims, and ordering ss spokes.  Planned next is powder coat the frame/swing arm, but first a three week ride on the shadow.

Nice cleaning.  I just did my rear tire today, did you have trouble pulling your axle out?

Tracking down parts.  Finding the tank latch and center stand was easy but does NE1 have a 4-4 exhaust they want rid of?  A decent right ear?
  The frame/swing arm has been powdercoated a gloss black. Painted a couple small parts myself.  Pictures of all that soon.  Not going needle, and left the stock brass bushings in place.  Thanks for all the posts out there on how to remove the rubber swingarm bushings.  Had to do after powdercoat, and used the socket method.  Left a couple dents in the swingarm. Removed the paint on one side, one side didnt.  If I had to do it again would try a shim (large washer or two, wood?) between the socket and that the ridge on the swingarm....oh and do before powdercoat duh :P
  Spokes came in from Buchannas, front was perfect fit. Lost (deleted?) all old pics of front wheel, that made lacing a b!tch for a guy thats never done it before. The back outers had to be exchanged(damn shipping costs)  and the replacments didnt fit either, couldnt even froce them thru.  Ended up shaving the holes with a drill little at a time, and If I had to push hard made sure the hub dented in line with the spoke.  More sand blasting next week, and smaller parts to the powdercoater. Sould be truing the rear wheel next weekend *crosses fingers*

I'm pleased with it.

If theres anyone out there reading this that has a link or advice on removing&reinstalling the flash/oil/neut/beam tag on the top bridge please feel free to share it.  Otherwise I'll be wading thru the search engine on Sunday.  Thanks in advance :)
Climbing the learning curve, progress is slow but steady.

That wheel looks great! Good job cleaning up that hub. Glad to see you're ressurecting your buddy's bike. Keep it up and post pics !

More progress yesterday:



  Didnt like the black shocks that were on the bike, so picked up those.  Need a washer for the top of them, used all four that came with them for the clevis @ the swingarm (is that right?).  Going to Sandblast a few more parts next week, drop them off at powdercoaters and will true up that rear wheel when I get the centerstand on. Having a hell of a time with the top rivet for the ID tag, could be welding slag back there or something, cant drill thru it. Might fake a rivet there and super glue the tag on.

Wow, long time with out an update. Turns out the engine had been big bored in the 80's, special thanks to the Old Motorcycle Shop here in town for doing the rebuild on the engine. Cleaned it up the last few weeks and got it in the frame a couple days ago. Got a little work done today with the wiring harness, oil tank, pedals and rear brake hooked up.

My original vision was a fully restored/ practicaly new bike, I've realized I don't have the time, money or patience for that. If it's cleaned up and mechanically sound when I'm done I'll be happy, maybe slowly transform her into a cafe racer after that. As usual lots of great info here! Hopefully post a little more progress soon.

Few more parts on today, down to one milk crate of parts, including the carb. Almost at the end of my skill set, could have the shop finish her off for me.

Expand your skill set, we'll help! You're so close, and you can do it right for less money. Rather than trusting someone at a shop (cause it's not their bike!) looking good so far. ;D

Well it's taken awhile, tons of thanks to the local shop for setting up the carbs and doing the final touches. Took her for 1st ride today, probably been 20+ years since she's seen the streets.
