CB750 / Re: 750F2 clatter

Hi yoshi
Thanks for the reply ive already done the cam chain and timing is spot on only thing ive not done is tappets and carb sync so once these are done hopefully the clatter will lessen the bike runs great as it is but if i can quieten the noise thats only noticeable at tickover i will be a happy bunny

Hi john
Thanks for the reply the timings spot on so i will check the tappets and sync the carbs to see if this improves things

CB750 / 750F2 clatter
« on: August 28, 2021, 02:56:32 PM »
Hi all
Ive a 22000 mile 750 F2 and ever since ive had it it makes a lite clattering noise when ticking over at around 1100 rpm noise seems to disappear when around 2k rpm and above, it sounds louder from the clutch than any other part of the motor and makes no difference when pulling the lever, ive been told it coud be the primary chain , i always thought it was normal but ive heard other 750s that  dont do it, has any one else experienced a similar noise

Cheers bob

Hi the bike burns no oil and does not smoke i have canned the knackers of it only a couple of times at full throttle in all gears and yes in the lower gears it accelerates better as you would expect and i only did this to try its not my intention to thrash it but as ive said all along i just thought it would rev quicker than it does i may try a 14 tooth frnt sprocket anyone tried this opinions please

Thanks for the replys maybe I am expecting too much from it I had a 77 f2 4 years ago and don't recall it being like this plus maybe I've been spoilt by modern bikes although I am suprised that I can run at 2500 rpm in top and open the throttle and she picks up with no hesitation seems to be quite torquey low down

Points gap in spec and timing spot on bike idles evenly with no issues through rev range so im guessing carburation is pretty good or am i expecting too much im not after masses of speed but it feels muted ii has a motad 4/1 plugs are new as are caps and air filter

With the throttle wide open it just seems so slow to rev

CB750 / 750 f2 gearing
« on: August 22, 2020, 03:05:05 PM »
Hi all,

After recently aquiring a 1977 cb750f2 im over the moon with it, yes it has a few things i want to do to it but over all it starts on the button and idles once warm, however when riding it seems to take ages to gain decent speed both rev counter and speedo seem to climb slowly, im beginning to think it may be over geared, the bike rolls freely and brakes dont bind. Rear sprocket is 43 teeth not sure about front still need to remove the cover, speed wise in 5th gear its doing 60 at 4k, 75 at 5k and 90 at 6k is this right any advice will be greatly appreciated, thanks in advance

Hi all
        Is there a specific side to pull the carbz out from a 750 f2 which makes it easier also anyone brought throttle cables for the f2 from david silvers if so are they any good

Has anyone faced issues insuring these because i found that most places class this as a 1978 748cc not 736cc its becoming a pain to find an insurer who recognises it as 736cc
