Hi all
my F1 on standard setup has a small niggling start-up running problem which your thoughts would be appreciated on. when starting (with choke) starts and runs on first touch, take choke off and ride, after 15 mins or so, the engine speeds up from 1500, to 2500, reduce tick over adjustment screw, and all is great as normal, but when stored and restart, you have to readjust the tick over screw again to gain revs to 1500 and start the same process again?
any ideas please?
thanks
John

Good morning all, do any of you use a fuel additive (leaded fuel additive) I am unsure whether to add some to my 1976 F1, or is it needed at all? If so, what would you recommend? would the newer fuels run hotter and possibly damage the exhaust seats?, the lead in the older fuels was also a lubricant I believe.
Thank you all in advance

Hi all the front brake is sticking 0n on my CB750 F1, moves ok forward, but can feel resistance when pulling the bike backwards? not sure where to start, front caliper or master cylinder? not a lot of resistance, but enough to fail MOT (all seals replaced on re-build).
thank you

At last, just applied for my historic road tax today, 1976 F1. easy done at the post office. that £86 now goes in my pocket instead of the chancellors.  Anyone having a bike over 40 years old (registered before 1st Jan 1977) can now apply John

Hi All
starting the engine is getting worse, push button, then horrible noise (sounds like starter clutch not engaging)? what parts would you suggest I should try and source to fix the problem? I think part No 28120300000 is the main item needed, but no stock anywhere that I can find (any ideas on where to get one). and is it an easy repair?
Thank you all in advance
John

Hi All, yet another issue with the carbs, No 1 choke seems to drop out of its slider bar (small bar inside carb from choke leaver to choke), therefore choke on all the time. I have taken it all apart and cant find any real issues but have replace the choke and link bar from another set of carbs, but it has done the same again? any ideas to solve this would be appreciated.
Thanks

Hi Guys
I am having problems with No1 carb. it seems like its not letting fuel through. normally to test this you can undo the balance screw and squirt some WD40 or similar into the hole and if the engine picks up, you know fuel is not getting through. but when I undo the screw, the engine revs up and exhaust gets hot without the added WD40 (normally it would slow a little before squirting the WD). in some ways this is good news, but where should I look for the fault/blockage-airway? any ideas/solutions would be welcome.
Thanks in advance
John

Hi all, The headlight on my CB750F1 1976 does not have a place for the parking light bulb? when looking at replacements, they seem to be convex, and mine is concave? it has K4 made in Belgium on the rear. I have taped it to try to see what it is made of and not sure if it is glass or metal?
Can anyone offer any help please
Thanks

Hi all, I am still having issues with the plugs coking up, I have tried all the obvious (balancing, hotter plugs, raised needles, new jets, plug caps, coils, etc etc, but still cannot get it right. I don't want to sound defeatist, but does anyone know of a good tuner who can help in the Essex area please.
many thanks for all your help,
John

I all, I have been looking for some jet holders for a CB750F 1976 for some time, and not been able to find any (1615-341-004). has anyone converted either newer or older style carbs to fit, or adapted the existing cabs to take other jet holders? your help and advise is always appreciated.
Thanks

Hi all, I am after a set of needle jet holders for my CB750 F1, part No 16165-341-004. does anyone here have any spares they would like to sell, or know where I could get a full set please? I have seen some listed on e-bay for the F1, but part Nos are different? DS and CMS lists as no longer available,
many thanks in advance.

Hi All, I have just completed a compression test and found that the results are, 1-2-3 test gives results of 138psi. no 4 is at 150psi, after placing oil in the head of each, the results go up to 175psi (test done with engine hot). I have checked my Climers manual, and although it tells how to do the test, it does not give what the results should be (except + - 10%)? the problem I have been having is coked up plugs, and trying to determine what the problem is (even though it does not appear to be oiled up plugs), thought it best to check anyway as this is the easiest test) I have also moved the clip on the carbs to the highest setting, and this does not seem to have solved the issue? any thoughts/help would be appreciated.
many thanks
John

Hi All
I am looking for new main jets for my CB750F1 (1976) The standard is 105, and looking to go down to 100. E-bay and the like do have loads of jets for the Keihin carbs, but not specific to each carb type, so do not know which to order? any help would be gratefully received.
Thanks
John
