ya, I saw those.
I have been thinking about getting some repros for the time being, but I think I want to put something else on there all together (if I can find something that i like) benji said that he can make some that are nice, just looking for other options.

 :D

My F bike is in pieces all over the floor and shelves of our shop. Hopefully it's all together and to my liking by spring. I also hope this winter project keeps me from going insane when there is snow and salt piled up all over Wisconsin.

can anyone give me any specs (length), and routing pictures for throttle cables with low bars.
I have drag bars now, and after I changed from the original bars I have had trouble keeping the line from touching the pipes.
You can spend some time and remove your head light and Speedo & tack and rerought the cables .
You want to make sure there are no sharp bends and it does not bind when turning the wheel left to right.

Anybody know how a 75 750F engine differs from the K engines and later F engines?

Someone posted a link to a chart that showed the engine modifications by serial number over the years. It was on this board, but I don't remember where I saw it, sorry. It was in the Tech Forums, I believe. In general, I think the K bikes saw decreases in horsepower through the years, and the F had some changes in gearing. The gradual loss of power may have had more to do with emissions control and carburetion changes than the engine. Thoughts of Hondaman in the FAQ section has a lot of good information about the K bikes but not much regarding the F engines.

There are frequent comments about premature valve guide wear in the 77 and 78 F engines but the guides can be replaced with beefier versions.

Disclaimer: I have never actually been inside one of these engines, unless you count adjusting valves and replacing sparkplugs. Just going by what I've read here.

Here's my '77F.  Just finished it up at the end of the summer, and would love to keep riding it, but with Iowa's lame excuse for fall weather I'm not thinking I have much time left....  I got snowed on this morning...

Looks like I might be back to modding soon.

anyway, here's the pics.

Since this is the 750f thread i figured i would make this my official introduction. Im Sergio an i recently picked up a 78 cb750 supersport with 49k miles, although im not new to classic honda's this is my first 750. The previous owner had limited mechanical skill and probably did not know how to adjust the throttle/fuel issue i fixed. Needles to say , i have the bike running top notch and am absolutely satisfied with the purchase. I sit and stare at the bike and i realize its perfection the way it sits with few modifications, i cannot make any alterations without feeling guilty.glad to finally be part of this community, from SoCal

srust58- thanks, I wanted some sort of design on the tank, and simple is always the right way to go in my opinion.... I just wish I would have had my straight tank ready to go. Have to duplicate it on that one over the winter.

Caddux- Welcome to the site!  There is a ton of useful info and a whole bunch of great members.  Looks like a really nice clean bike you've got.  They are great machines thats for sure. I love riding mine.

Great to see this thread.  Here is my 77 750 SS.  Only had it a couple months.  Picked it up local and had to replace the head gasket but she is sweet.  I was concerned with the rpm's I was running while cruising at 60 so I added one tooth to the counter sprocket and it really helped it.  Now I am really liking it and enjoying riding a SOHC again.  I had almost forgotten how much fun they were.  If the seat looks a little odd its because I took a touring saddle seat and cut it down and had it recovered to near stock.  Here she is:

Just curious about something while it is on top of my head. Has anyone swapped the carbs from a 77-78 750F to an older model F? I have a 77 and a 75 and they are both non op but I might be able to have everything I need if I combined the two. Eventually I will get em both going but I am dying to ride again. What is incompatible? If there are too many to list forget about it, just consider this my subscription to the thread.

Great Idea Cudjo. Your keeping yours now.... right?
Bought my 77 f stock last august and this is what it looks like today. Waitting to change a couple more things. Changing the front MC, -1" front fork tubes, progressive springs, shorter brake lines f & r, shorter clutch and throttle cable. Its getting a headlight make over as we speak with a triumph headlight switch. Its been a great project and kept me busy over the winter.



Where are you hiding the oil tank? Looks great. I'm still bondoing the dent in your old tank that you sent me. I should have it painted in a week or so.

Edit: Now I see it. Is that something you made or did you buy it?
