I like the little front fender plate ala euro look. Where did you get it!

Google "Pedestrian Slicer"

So I notice they have them for different bikes, would it be safe to assume the fender arc's are all about the same?

They're going to be about 95% 19". But if you got a 18" or have an 18" fender and put a 19" plate on it...I'd be able to tell the difference.

So I wouldn't assume.

I'd post up but my only F has one too many cams for this place!

The Fender Plate in my bike is from Carpy's shop

Does the stock exhaust clear the disc brake hardware OK?

I was a bit scare when I replace the 4 into one and put the 4 into 4 but the only problems that I found are as follows:
1.-Relocation of the left side stand (I weld a plate to the left engine guard)
2.-Installation of the K stiled exhaust flanges.(just bolt on)
3.-The pillion foot rests stay in the F2 position then a small plate must be fabricated
to fix the exhausts to the frame.

The brake system including the rotor is the original F2 no mods whatsoever

Thanks, I was thinking it couldn't just bolt on.

My brother has a chiltons manual for the 750. He says it has a section about 750F engines, F0 and F1 included. That there is a problem with the valve keepers and they fail regularly. It is reported to be bad enough everyone with an F should consider installing a K head.
I'm calling Bull Sh!+. I've never heard of this. I know there some claims about the F2 and 3 valves which may also be exaggerated. Anyone else ever read this?

I think "ofreen" may not agree with chiltons

Agreed. He needs to remove the 392 head from his K7 then too.

Retro Rocket · « **Reply #861 on:** July 25, 2012, 10:27:14 PM »

F2 and F3 had valve guide problems {premature wear}due to the bigger valves being at a different angle to the earlier valves, to make them fit inside the combustion chamber, there are replacement guides that fix this problem, Nothing wrong with F0 and F1.

Jerry Rxman Griffin aka MuthaF'er · « **Reply #862 on:** July 25, 2012, 11:30:39 PM »

F0/F1 have the standard/normal/regular keepers as does the K7.

The F2/F3/K8 uses the newer keepers. The F0/F1/K7/K8 all use the 392 head.

The K8 while using the 392 head also has valves that are cut/slotted/grooved for the newer keepers.

The K8 uses the F2/F3 stronger valve springs too.

I have Clymers, Chiltons, Honda and Cycleserv manuals and they ALL have mistakes.

Hi guys,

Quick one for you: Can anyone with an F0 or F1 tell me if the lever on the inner side of the brake pedal shaft (the lever that connects to the brake light switch spring) makes contact with the frame when the pedal is in the "up" position? I'm completing a basket case project. The brake seems to work fine, but I've noticed that the lever makes contact with frame whenever I release the pedal.

Thanks!
Aaron

Aaron,

The hole area of that shaft piece that the rear brake light spring connects to on mine is about 1" from the frame with the brake pedal in the resting state. There is some adjustability using the piston rod shaft which could be the problem. Other than that perhaps that shaft piece is for the wrong model?

aperry · « **Reply #865 on:** July 26, 2012, 07:03:38 AM »

Thanks for the quick reply Jerry! Piston rod adjustment sounds like what I missed. Of course, I could have some incompatible parts too. I thought all the parts at play here are F1 but I could be wrong.

Ha! It just keeps popping up.

Yes, the seat is a one off custom seat that I made myself.

But - after riding a beautiful stock CB750F1 through upstate New York last weekend, I really wish I had kept this one stock and just restored it to top working condition.

Fun to do the work, huh! The thing I like the most about it is the "saddlebags"! Nice custom touch.

david 750f · « **Reply #869 on:** July 26, 2012, 01:01:35 PM »

Aaron, are you sure it's hitting the frame and not the bottom of the footpeg?

aperry · « **Reply #870 on:** July 26, 2012, 01:15:02 PM »

Hi David,

Yeah, here's a pic I took the other day. You can see two problems.

1. The issues I described above (that little lever hitting the bottom of the frame). Pretty sure Jerry is right about the piston shaft adjuster. I was just looking at this and it looks like a little adjustment the makes a lot of difference in the lever travel.
2. I think my spring holder (for brake light switch) is from a K model. I just ordered a banjo bolt with switch built-in for $15, so I should be able to get rid of the spring altogether. I'm not a big fan of that thing anyway. This is how my front disc is hooked up so I can have a single brake line.

Looks like you must have gotten an older swing arm bolt with the zerks on the ends.

aperry · « **Reply #872 on:** July 26, 2012, 01:54:22 PM »

Yeah. I think it is an older one, not sure. It seems to fit well otherwise.

The biggest problem is that the spring holder has a little bracket that holds it pointed downward, instead of toward the lever that the spring attaches to. I would assume this is a K holder, and a F holder would be pointed differently. I had two choices: grind off that bracket and point it downward, or go with the banjo that has a switch. I decided just to go with the banjo, which seems a little cleaner to me.

I have a '75F that was stock when I bought it and had never been worked on so everything was as from the factory. I took hundreds of pictures as I took it apart so I would be able to refer back, i'm super anal. In looking through these pictures it looks like I have maybe 12 or so that show the stock rear stop light switch, mounting, etc. I can put these into a PDF with one picture per page and send it over if you provide me with an email address. What I did was shoot the picture in very high resolution in case I ever wanted to blow one up, so converting them over to a PDF creates a much smaller picture, are you interested?

aperry · « **Reply #874 on:** July 26, 2012, 02:37:01 PM »

Actually, that would be really awesome. All I'm interested in is the stop light switch orientation, and any pictures of that inner lever that holds the bottom end of the stop light switch spring. I'll PM you my email address.

Thanks!
Aaron
