I have my CB750 tank down to bare metal and it's got some dents, I hate to lay filler on it and would probably do a bad job on it.. Called a local guy and he hadn't invested in a jig/setup for tanks but gave a recommendation for a place 45 mins away that does great work.  But I can't get anyone to look at me sideways for $100 around here. 

Yeah, I honestly didn’t know much about this dent removal places, it was suggested by a member, but as I said I’m very happy with the results. I was going to try myself but it’s something that I have never done and really wanted to preserve the paint and decals. And it would had cost me as much just to buy the tools and probably I would had ruin it and ended up painting anyway lol
So for $100 was definitely worth it.
I ll post some close up pictures in the next few weeks

That’s crazy, yeah I was expecting to cost a lot more  honestly, but this guy was super awesome to work with and seemed pretty excited about bringing back a old tank.

Progress update
New parts came in.
Rear end it’s pretty much disassembled a lot of parts to be cleaned and some polished some painted.
 Still need to remove swing arm to clean, replace bushing and greased. Got to replace this old shocks still debating on what to get I’m looking at a set from Cognito Moto or a set of Hagon. I ll be removing the front wheel so this week I can install new wheel bearings and new tires, clean rear brake and install new shoes. Once that’s all done will give the wheel a nice clean and polish before reinstall.

Quick update
I did remove the old shocks and order a set from Cognito Moto hopefully I made the right decision only time will tell. I removed the swing arm, it has some rust spots I ll sandblast it and paint it  along with the center stand and a few other parts hopefully sometime this week.
I removed the front wheel and started disassemble the front end.
I really want to get the tires and wheel bearings installed, sandblast and paint this parts, and install new head bearings this week or in the next few.
Thanks for looking

Wow!! Your bike looks awesome!!
Thank you !

Thanks and yours is making good progress. Your tank came out great.
My 75 was put away properly every winter in NH and my friend that had it before me asked me years ago how to do long term storage. He had drained the gas out of the tank and carbs, fresh oil and filter. The bike was put in his dry basement that stayed above 50 degrees because of the furness and he kept the seat, tank and side covers upstairs in a spare bedroom covered, on top of the old bed. It was a fairly easy prep to get it running again after 12 years setting down there. Thankfully he kept it kicked over each year so a new battery, quick clean of the jets as the carbs had no build-up in them, flush and bleed the brake and I had it back on the road. On one of the first rides I got pulled over for cracking it open on a 40 mph twisty road. I went by him doing 60.... Thankfully he was in a good mood and understood my just getting it back on the road but reminded me it was a 40 mph road. I've been over the ton there in years past on my original 750s.

Keep up the good work.

This past 7 months I've been helping a friend bring back to life a 74 his father in law gave him. I had to strip it to the frame as there was a bunch of rust on the frame and bad engine paint from setting in a rat infested shed for 33 years.
It's going back together now. Just have to order some new seals as I pulled the engine covers off and polished them while the motor is out and will be replacing the rubber pucks in the head as they had been leaking.

It looks like a good project
Yeah she’s not in bad shape for been sitting for so long, I was thinking about pulling the engine and paint the frame but honestly I got not real reason for it engine and frame paint it’s in good shape, no rust really. I figure i ll get it on the road and if in the feature I pull the engine for any reason I ll take care of the frame. However the swing arm, both stands, and battery bracket had good amount of rust, so those I’m going to paint. Engine still needs to be polished along with all the chrome parts. But I think she’s coming along nice. Hope to have her on the road late winter or early spring.

Shocks came in today.
Shipping was super fast I only ordered them on Sunday.
They look good and well made, thanks to Cognito Moto, but just by taking some quick measurements from the old once it looks like I’m going to need some spacers for the top and bottom. For the top the stock are a bit wider than the new once and at the bottom the stock mounting point it’s a bit narrower then the new once. Of course I m not sure about performance.
Nothing a few washers and spacers can’t fix.
I ll update once I ll mount them.

Forks are drained and off, ready to be cleaned and rebuild.
Next I ll remove the triple to upgrade the head bearings, the triple I’m going to sandblast and paint, it has a lot of rust. Also started to paint and polish some of the parts I ll post a a few pictures of that soon, waiting for everything to fully cure.

My first cb750, which I rode constantly for several years in the '70s including at least three long trips, was a '75 in Flake Apricot Red.  Honestly, while Honda offered some very fine colors then, I think the Flake Apricot is the most beautiful.  I am envious, as I wish I had that bike back.

Got the new head bearings installed , paint the triple tree, and got the new rear brake shoes installed.
The rear wheel it’s ready to go back, probably do that sometime tonight.
After the rear wheel it’s on I ll be working on the forks and the front wheel.

Looking great, when it gets on its own wheels there's a sense of the finish line in sight, feels good.
