Hey guys, what's up! I've been lurking here for about a month now, but I just got my new bike today, so I figured I would finally introduce myself.

My name is Vince, I'm 27, and I've been riding since I was 13. My first bike was a 1978 Yamaha DT100E Enduro, which I just restored a bit and sold in the past week. Friends of mine have let me borrow their rockets for a season, but I finally just bought my own first "full-size" bike, a 1980 Honda CB750F Super Sport.

I picked it up and rode it home today for $500. The bike is in really great shape for the age, has a clean title, and rides great. He also had the original 2-Up seat and stock taillight, rear fenders, and a Clymer manual! I just need to do a head gasket on it, which won't be a problem at all. It's a heavy beast compared to what I'm used to, but I can't remember the last time I was so damn excited about anything in my life.

Now, it's not exactly a Cafe Racer, but I have been told that certain things about it, along with certain things I'm interested in doing it are in the CR style. I can say that just checking out the Project Builds has inspired me so much already! You guys have some amazing bikes here, I mean it.

Enough babbling... Here are two pics that the last owner took. I'll be adding many more as I clean her up and bring her back up to spec =)





Take care!

so gay......



ok so here is what you want to do. You want to go to cb1100f.net and get real familiar with the classified there. These are the parts you want:

- European Sport kit foot peg set
- brake calipers and mounts from a 1981 or 1982 cb750F/cb900F
- Kehin CR carbs or a stock airbox with a K&N filter in it
- a decent set of shocks (stock cb900F, vipex, ohlins, etc)
- turn signals. not the stock ones.
- a pair of the stock side covers.

it is a shame the previous owner ruined the bike with that cheap as shit vietnam seat. The stock bodywork had real superbike racing cred and could have been made to look the business with a taillight tuck, fender chop, and LED setup. Instead you have something that looks like it was re-purposed off a 1970's Schwinn. It isn't ugly per se but it tries to make the bike "older" looking than it is which automatically lumps you into hipster douchebag territory.

psst....it is not a style, if you look at it from a purely aesthetic angle you will end up with a bike that won't "work". If you genuinely try to improve how the bike functions, you will end up with it looking how you want anyway.

I fully understand the douchebaggary associated with the flooding of "cafe racer culture" these days. I've read too much about it on here and seen how you guys converge on it like white blood cells to an infection lol. Trust me when I say that I want to do this thing right, and by right, I mean to have function and form that I will personally enjoy.

I actually just registered at CB1100F.net and started reading on there in the past hour or so; I see a lot of great stuff on there as well. I appreciate the list you gave me! I can see that I have a LOT more reading to do on mods for this bike. To be honest, I was dead set on an early to mid-70's CB650 because it's what I grew up with my dad having. But this thing just kind of jumped out at me, especially for the price and proximity to home, so...

Just to kind of go down the list:
- Been trying to research foot pegs vs rearsets, etc all morning. Thanks!
- Is this for function or form? I already have dual disc in the front and the brakes in general do an amazing job just driving on the street...
- I'll look into it! It already has Kehin carbs on it, I'm just not sure if they are the CR's or not. It's going to be fun either way, though, because I've only ever worked on Mikuni my whole life.
- Rear shocks? What's wrong with them? They are the famous FVQ adjustable (so I've read).
- Not sure if I want turn signals. Not needed in Illinois to ride and, actually, every bike I have ever ridden on the road was lacking them so I have gotten quite used to hand signals while riding.
- Again, not sure if I want the side covers. I want to put the stock seat on (the current one is nice support on the rear, but I agree it looks kinda...not ugly...just, frumpy I guess, on top of having junk construction), take off the Euro style fairing and see how it looks naked. Not exactly a function thing per say, so I'll run some trial and error and look at a few thousand more pictures until I figure out what I like on it.

Input appreciated, however, on all levels! You're obviously really knowledgeable, so I'll take anything you say to heart.

Dude, if your bike works and you plan on making it work better you belong here.

Raask makes rearsets for the bike but they work and fit like 1970s parts. The sport kit was made to homologate the part for prodiction racing. There is a bar that goes with it but you don't need it. This means they are designed by Honda engineers and work as such. They are not as high and tite as the raask but the bike is so long and heavy you don't need the full race tuck.

At some point you may want to consider the cb600f2 wheel swap.

Brakes: 1981-82 cb750f/900f are dual piston calipers vs your single piston jobs now. If you think your existing ones work well, wait till you see how well the dual piston calipers work. This is literally a bolt on mod, works with your existing rotors and wheels. The 81-82 rotors are slotted for better cooling but you don't need them unless you are racing the thing.

Carbs - yes it has stock keihin CV carbs on it. IT DOES NOT have keihin CR carbs which are fucking awesome. Do your homework. The stock carbs are hated pieces of shit. The CR carbs are $600-800 and WORTH it.

Shocks. Yes the original shocks are variable and better than anything that came before. However they are also 30 years old and filled with an oil slightly too light. Also the spring is a compromise. I would rather have a set of new non adjustable shocks than 30 year old stockers. Plus I would want springs setup for my weight. If you weight 150-165 lbs most shocks will fit you out ofthe box. If you are 200+ you need springs.

I have stock seat for sale if you want. It is $140 shipped and I'll even throw in a stock tail. However make sure the PO did not cut the rear frame rails, otherwise it won fit.

Purchase a good set of turn signals and figure out how to use them properly. Any time you take your hands off the handlebars, even briefly for a hand signal, you are sacrificing some degree of control of the bike in that moment.

Additionally, if you haven't taken an MSF Rider Course, please invest some money in yourself and do so. The life you save may be your own. Illinois has a great state-run MSF program, although there may be a sizeable wait for a class since they can't run year-around like we do here in Arizona.

No signals on a 1950s/60s Brit bike cool. No signals on a 1970s/80s superbike = gay.

Ideally you want other drivers to see you an most drivers aren't used to looking at hand signals.

If you look at your laws closely it will say if your bike originally had them you have to run them.

What is nice about the CBF is that wide panel in the back has a lot of room for flush mounted signals so it won't kill the look.

Geeto: Dude, you rock with that info. You probably saved me a few hours of forum searching in those couple posts, haha!

Emit: Aside from my dad when I was young, my friend is an instructor and she basically put me through course so that I could ace the test when I took it.

So, I'm digging at this thing a bit today, starting with seat and tank removal to prep for the head gasket and overall cleanup this week. Wow, whoever owned this thing before the seller chopped this shit UP! He gave me the original seat, which I began examining and almost NONE of the frame mounts are on the bike. Mucho disappointed... There aren't even any mounts for the under-seat rear fender. Luckily, there is a genius fab guy that works at the shop I'm at. Hopefully he can lend me a hand in between working on his Rebel project and other work here at the shop. I just need to find someone that did the same kind resto so that I have some kind of idea how it all goes together.

Also, after seeing so many pictures of builds and restos, I decided that I definitely want the original side covers and I want to do all plastic and the tank in white over the black frame, pretty much like this...



The contrast is sexy as hell (to me, at least). But, it will probably take a day of work just to get this OE seat back on. Also, I'm just over 200 on a good day and the rear shocks have probably seen better days. That first day/first bike excitement is wearing off (only slightly) and I'm finally starting to see this thing from a technical standpoint. It's not terrible, by any means, just a bit here and there to get her looking and riding like she should.

Just a question, if anyone has an answer...
What is a good source for good engine parts? I want to order up what I need for this head gasket, but I'm wondering if I should also order up some valve seals too, any and all top-end gaskets, etc, but I'm not sure what companies make good stuff, or if I should just go with Honda OEM all the way. I'm probably going to take the motor down between tomorrow and Wednesday, so I'd also like to order whatever I need to get it all back together before the week ends.

Thanks, guys!

if you are going to buy honda OEM parts all the way - then hondaparts-direct.com

however versah makes gasket kits that are relatively inexpensive and include every gasket you need. not entirely sure where to buy them but my local bikes shops never had any problem ordering them.

If the Previous owner hacked the shit out of the rear frame then forget about going back to stock.

by the way, the stock seat has two tabs that mount to the side of the frame by the shock mount. It is damn near impossible to cut those without making the frame uglier in that area, so check again. the seat does not flip up on these bikes.

Is it possible you have a K bike converted to F specs? what does the neck tag say?

Found this:
http://www.ebay.com/itm/Honda-1979-83-CB750C-F-K-SC-L-Vesrah-Top-End-Gasket-Kit-/200618531035?hash=item2eb5cbd8db&item=200618531035&pt=Motors_ATV_Parts_Accessories&vxp=mtr#ht_578wt_720
Think I can find it for cheaper? If it were your bike, would you do OEM or aftermarket (Vesrah)? If only Golden Eagle made bike parts...

I'll have to look closer at that today. I'm going to go transfer registration/title, then I'll stop by the shop and snap a couple pics. I do know this: the seat he gave me has a lock on it and some kind of hinge system, so maybe it's not the seat from a 1980 CBF SS... I'll also check the neck tag and make sure.

I think you can find them cheaper

the vietnam company that makes that seat sells it as a 1979-1982 cb750K seat. The cb750k had a hinge system to open the seat, the F bikes did not. Hence why I think you have a K frame with F bike parts. If you read the neck tag it should say CB750 K, F or C. the frames are all a little different between the bikes (the F bike frames are stiffer).

your vin number should also tell you what it is as it will start RC01 for a K bike and RC04 for an F

if you are in bitsa land it might just be better to buy a stock F bike and keep modding this one.

Vince, I am going to ignore the fact that you were "taught" by your dad and a friend of yours how to "pass the test". What I am not going to ignore is the simple fact that taking any state-administered, stand-alone motorcycle skills test is meant to assess entry-level skills, and nothing more.

If you didn't take your testing as an integral part of a Basic or Experienced Rider Course, you're lulling yourself into a false sense of security in the fact that there is so much more to learn than what you were taught ad-hoc. The female "instructor" you mentioned should be reprimanded herself for providing you with nothing but the basic tools to "pass the test" without admonishing you to really enroll and complete the course.

Some here have mentioned their experience with MSF courses were less than satisfactory - I would counter that the curricula, when properly administered by a qualified, enthusiastic cadre of Rider Coaches, will provide you with tools that will save your life some day.

Feel free to continue on your work with your CB-F/K (I think it's a K model as well, look at the footpeg placement and the length of the rear brake pedal for visual clues), but you should really set aside some time and money for self-improvement.

Emit: Are you really going to mince words with me here? Wtf...
Dad rode motorsports his whole life, taught me when I was young.
Friend teaches the class, taught me on the side for free.
I know how to ride, and whats legal and not. I do my research, I know what's up, I'm a newbie to parts and mods, not bikes.

Anyway, it's an R04 and the neck says F. A previous owner probably got this seat for a K and modded the F frame for it, although, not very well. It's only held on by one bolt and nutin the rear.

I also just realized I need the rear cowl after looking at the Honda Parts site you provided, Geeto. And what's bitsa? lol
