I'd like to mount some clip-ons on my CB750 k7, and Im interested in a cheap pair from partsnmore.com. These are 8" long and roughly 15 degree angle. I'm concerned about the large master cylinder fitting on the clip-ons, and then it interfering with the headlight/instruments etc.

I did a search and couldnt find anything on this. Any one have pics/advice on how they installed clip-ons and were able to fit everything without interference?

thanks

I went and replaced the old master cylinder with a newer one like this

Works perfect.

Do you know if this was necessary to avoid interference? For cost purposes I'd love to just use the existing one.

BTW: The bike in your avatar is SICK! I'm thinking of cafe/street fightering mine (hence the clip ons) and that sort of dirt track or box seat is exactly what I was looking at. What brand seat pan/tail is that? is it Airtech? It doesnt quite look like any of their models? Did you do the upholstery?

Thanks

I don't have your definitive answer, but the problem usually exists with clubman bars, where the bolt that holds the line into the MC hits the speedo. With clipons you can lower the bar below that point, and my understanding is that's not too low to still be comfortable. They are clipons after all.

Anyone have pictures to confirm? I've searched but can't find any visual reference to how anyone has done this.

Thanks

I have had clip ons on a couple of my old Hondas with the only problem being that the throttle cables were too long.

You know i remember having issue with the Club Cafe bars a little but i think i got past it somehow, cant remember how that was back in the 90's.

What kind of clip ons are you using ?
I say spend the money and buy the fully adjustable clip on. Telefix clip ons are the best and you get allot of placement options. And If you bend the bar you can replace just the bar. Or if you need a longer bar just cut up some old bars and you are set, or you can use aluminum tube. NO RUST.

Hope this helps

I think your worrying is in vain. Like they said, clubmans are what you have to worry about.

Turned my clubmans upside down and no problem.

You know pretty much where the MC is going to mount, just front of the fork tube(depending on how the clip-ons are constructed). I would just hold it in that area and see if you have any clearance problems.

I´ve got Raask clip-ons on my CB750.

Here´s a shot of the pullback angle I´ve mounted them on:

When mounted at this angle, you will have to reduce the steering lock or the clip-ons will hit the tank on full steering lock.

Here´s a shot of my choosen height, and as you can see I´ve mounted them just below the triple tree:

In this last pic, you can see how close the banjobolt of the brakepump comes to the tacho cable:

If I wanted to shorten the clip-ons any further, the banjobolt would hit the tacho cable.

what mm size would one want?
39?

A question for you guys with clip-ons: What must be purchased in order to use clip-ons?

It looks like,

1) Clip-ons
2) headlight mounts
3) turn signals
4) cable(s)?

Anything else?Maybe the 75-76 F models(no fork ears) can keep their headlight mount and bar mounted signals?

crazypj · « **Reply #14 on:** March 06, 2009, 08:51:06 AM »

I usually find ergonomics are wrong and levers are mounted way too high.
Usually the M/C banjo bolt will fit in area between instruments and headlight

We wish. Stock CB750 tubes are 35mm.

Thanks Dan, those pictures are great! Just what I wanted to show how the master cylinder might fit between the headlight and gauge assembly.

In terms of whats needed in order to mount clip ons, I didnt think that you would need to replace everything in this list... don't need to move the headlight, don't need new turn signals, and dont need new cables in all cases right?

Lights Out · « **Reply #17 on:** March 06, 2009, 11:03:29 AM »

I just swapped my bars for straightish sport/drag style ones. I had problems getting the master cylinder on there, it won't go any lower than the triple tree bolt. My front brake is way to high now and it's akward on the wrist. I guess my only option is to get a new MC, like the GSXR one posted earlier. Will that MC fit perfectly, and will the brake line attach sans frusration? From the picture on ebay it looks like the brake fluid resevoir is not attached to the lever and can be positioned out of the way. Is that the case?

Well, the clip-ons mount to the forks, so the stock headlight ears need to be removed. The stock headlight ears are what mount the headlight and stock signals, so other provisions need to be made for mounting them. At least that is my understanding. I don't have clip-ons mounted so hoping anyone who does could chime in and confirm or refute this.

i do have a question and i have beent hinking about it for a while, is there any reason why you couldnt make some nre fork top nuts, that have an extension on them the same diameter as the clip ons you want to use, this would put them above the top triple tree, negation the issue of speedo interferance, and alowing a wider range of clip on options?.

i mean you could locate them with a cap screw under the clip on so they dont move.

just a thought.

peace

You also expose the rusty part of the fork tubes. These can be dressed fairly well with sanding and chrome paint. The turnsignals can usualy thread into the headlight mount point, though some changing of hardware may be needed. Whatever replacement fork ears are used, can be drilled along their length for signals, or a bracket off the lower tree clamp bolts can be fabbed.

That's an interesting thought. Persoanlly I may not get comfortable levering the bike on a threaded part, though it may be perfectly strong enough.

For the same cost of fabbing, one might get overlength tubes from Franks, having length above the tree for clipons. Thee would also carry more air and give an improved ride...maybe.

Here are a couple of pics of the MC on my home-made clipons. It was really close to the fork tube, and the angle of the bars was determined by the clearance of the tank left and right.
