Wow.

I get it now.
I get why the 750 was such a big deal when it hit the roads circa 1970.

I just finished rehabbing mine.
I have a fresh motor and clutch, new exhaust rings, shimmed collars (mine were stretched) so the seal is TIGHT to the 341s, cleaned carbs with new rubbers and Honda made jets & needles, cleaned K&N filter with OEM airbox, straightened spark advance shaft, cleaned spark advancer, new TEC points plate adjusted as close to ideal as I can get it, fresh fork oil, cleaned & lubed swingarm bushings, new chain...
No more hesitating, popping, leaking, or pinging.
The sumna#$%* hauls ass and sounds like a Ferrari.
When it's in the power band and I roll on some throttle it GOES.

Now I better tune up the brakes.

Sounds like you took the red pill!

It's sweet when you take that first ride

grumpy · « **Reply #3 on:** March 06, 2012, 05:09:05 PM »

heh - it was an orange pill.

yeah, man. It's sweet when it all comes together.

It went from a rattly, popping, underpowered, under maintained, collection of aftermarket "improvements" back to what it was meant to be when it was new.

The bike that made all other bikes better.

Hey grumpy,

I can understand how you are feeling when all that hard work in restoring comes together

Please share pictures of your bike. It always gives me joy in seeing a fully restored Cb750.

I am also in the process of restoring a K2 to stock condition for the last 2 years. I am very close to completion by the end of this month. Hopefully I will also get a chance to experience what you are experiencing now.

good job grumpy,,enjoy,i wouldnt ride anything else,unless its a two stroke dirt bike.

grumpy · « **Reply #7 on:** March 06, 2012, 09:49:03 PM »

well, it's not really a resto.
there a few changes from box-stock: tail light, bars, seat (but it is 70's vintage), shocks, mirrors...

but it is cleaned up and mechanically put back to right.
going back to OEM cabs and pipes made a huge difference.
well, that and replacing the blown motor...

I love that. A few very tasteful mods and that color make it a real beauty.

Hell Yeah!The more I take care of my bike and fix all the lil things along the way,the better it gets.I rode to work the other day after a bunch of upgrades on the front end and really got on it in the powerband and when it pulls its so sweet,stable as hell now too.

What kind of fairing is that bikerbart?

bikerbart · « **Reply #16 on:** March 07, 2012, 05:24:39 PM »

Rickman Centura.

grumpy · « **Reply #17 on:** March 07, 2012, 06:27:26 PM »

YEAH! that's a lotta orange!

what's that silver thingy just above the airbox? Is that the key?

andrewk · « **Reply #18 on:** March 08, 2012, 03:22:02 AM »

Sometimes I wish my bike were still orange (Got repainted well before I owned it). I'm currently doing pretty much what Grumpy is doing to his, although I'm using aftermarket exhaust. Either way, I am sure it's a blast to ride with everything working correctly- can't wait until mine is in the same boat.

Keep up the good work!

Where is powerband? 8500 pops in mind, seems high. I didnt get over 5000 yet, seems plenty strong/loud there.

andrewk · « **Reply #20 on:** March 08, 2012, 04:36:17 AM »

You mean redline (Maximum engine RPM)? 8500-9000 is where I would stop. 5000 is just getting warmed up

70CB750 · « **Reply #21 on:** March 08, 2012, 04:44:04 AM »

Only our local small roads - and me being chicken - is to blame I didnt get there yet:)

bikerbart · « **Reply #22 on:** March 08, 2012, 09:58:40 AM »

Yeah,thats where the key is.I have a frame kit so the original location didnt work too well.I kinda like it.All I need to do know is get a cafe seat and paint that orange

KeithB · « **Reply #23 on:** March 08, 2012, 12:53:17 PM »

I hear what you're sayin' Grumpy!
I have V twins, parallel twins, V4's but nothing sounds quite like the Cb750

That's the truth.

Very nice job on the bike, grumpy.
