That is utterly fantastic!  What do you use for the black on the barrels?  That's not stock paint, is it?

Thanks for checking out my build.  I use VHT engine paint on most builds, this bike has satin black.  It works great as long as you do all the proper prep work and then bake the parts in an oven as recommended.

I think I accomplished what I set out to do.  Build a nice 750 sport cruiser with out losing the "vintage feel".  I wanted something I could slap a tank bag on (sorry Nvr2old) throw on some riding grear and take off for a few days.

The bike looks beautiful, tweakin..absolutely gorgeous.  I think you more then accomplished your project's mission.  Not to worry about the tank bag.  Just put a microfiber towel between the tank and the bag, and it should be fine.  Proud to've been a part of it.

Thanks Larry!  First thing people see is the paint, another excellent job!

Dude!!!  You do some great work. :)  Much quicker than I am  ;)  I'm almost done. Tried firing it last week but no oil pressure. Won't burp even pouring 3/4 qt into the oil pressure gauge galley. Sucks but looks like I'm gonna have to remove the exhaust then oil pan and pump. Kicked back to reflect and do some actual work now.
Thanks Jerry.  Did you prime your pump?  I always submerge my oil pumps in oil and turn them over by hand to burp out any air bubbles before install.

Not yet  ::)  Thought about it after buttoned up and in frame. (no DOH emoticons to insert here) Took a chance and lost  :-[ :-[ :-[  I should have some time to get back to it after this week. Even put in new shaft seal, spring and rubber plunger! Why would I remember to do something simple  ;) Isn't second time ALWAYS easier!
Quit banging on a keyboard and spin some wrenches. Your gonna be too old to ride the thing at this rate. ::) ;) ;) ;) ;D ;D ;D ;D ;D ;D

I can't begin to tell you how much this thread warms my heart.......Confused? let me explain.

I bought that bike originally in 2005 from seth rosko who claimed he got it from the original owner in NJ. It is actually how I met Rosko and what's more I bought it through a classified ad on this forum. I kept the bike for a while at the skate park that Rosko sorta managed called the Autum Bowl, and it was over a few wrench sessions there with this bike that he decided to bring the Vinmoto email list that was working in chicago and I decided to try to get the few scattered members of the VJMC in NY more active.  If you have ever been to the Vintage motorcycle show on N14 in brooklyn - it exists in part to this exact cb750F.

I put those dual piston calipers on it. The sidecovers were black because I accidently stepped on and broke one of the original red ones and I had a set of the black ones and decided to just use them instead. I believe the left one was actually an NOS one I had been holding on to for years. I still have the rusty stock honda muffler off that bike in a corner  of my shop.

I had the bike running and rode it for about 100 miles before putting it in storage at my parents house. Fast forward to last year, Jaguar contacts me and convinces me to sell the bike to a friend of his who wanted to learn to ride and really wanted a CB750. I sold it and the kid had it for one season before he blew the engine on it because he did 0 maintenance on it (literally he ran it out of oil after riding it 5000 miles). I was so heartbroken that the bike was screwed up that I didn't buy it back from jaguar when he offered it to me at a friend price (he had acquired it in a part trade for a cb450 to the same friend). I thought it would just be parted out and scattered to the wind.

There are some bikes in this world that carry with them a special aura. I don't mean specific brands, but specific bikes (ask me about the"cursed dream" some other time). This one bike brought two friends together who helped grow an otherwise dying motorcycle community in NY as well as help a new rider get his wings. Positive motorcycle things tend to surrond this bike and I am glad to see her in such great condition and enjoying a second lease on life.

Plus if it helps - when you go to sell it you can say it was once owned by both thwe founder of NYC vinmoto and the former VJMC rep for NY.

I guess this is just my long winded sentimental way of saying great job. I don't know anything else about the bike's life from 1978-2004 but I did once take an inspection sticker off it from 1985 so I am going to guess most of it's life from 1985-2004 was spent in the back of a NJ garage.

Sorry to revive an old thread, but as a fellow f owner I have one very stupid question...  Where the heck did you hide the horns?  Or did they just get deleted?

Also great job, the bike looks incredible!

Don't worry about reviving this thread, I am happy to see it pop back up...

The horns were relocated to the battery box.  Mounted under the box is a single high output horn.  Never really cared for the dual horns on the front of the bike.

I agree, the front end looks much cleaner without them, and a little more period to the 70s.  The dual horns always remind me of the more modern-looking DOHC bikes.

Took the day off to put some time in on the 1978f, now I have a roller.

dual piston calipers all rebuilt.


Here is the roller









This is a big step for motivation, Larry's fresh paint sitting on the bench also helps... ;)

tweakin - where did the dual piston calipers come from?

Sorry for asking questions on an old thread...your bikes are amazing and I hope I can be as good as you someday!

FYI. The calipers I have are for both 1985 Shadow 1100/VT1000C models.  It's my understanding that these are compatible with F3 models.  I got them for $65.

tweakin,
with the dual pot calipers, what size master cylinder did you go with?  the 14mm or 5/8"?  did it provide decent 'feel' and stopping power?

thanks,
nick
