New member says hello
« on: July 05, 2007, 10:45:16 PM »
Hello all,
Ive just bought a US style 78 K7 off Ebay,did anyone see it/go look at it?
It seems pretty good,no leaks from anywhere (except the fork seals) and the engine starts & runs well with no smoke.I am amazed how well it starts from cold or hot with the kickstart.I will say though it has a rattle/rattles about it on tickover which disappears with the slightest of increase in throttle,it seems slightly louder on the offside.When i pull the clutch lever in the noisiest rattle goes leaving one that sounds like an old Singer sewing m/c.
Would i be right in thinking the clutch basket has a problem,whats the fix?
Is my camchain making a noise also?Ive read a couple of posts about people adjusting the tensioner,i thought they were self adjusting,again,whats the fix?.
The front brake is a single disc that is so pathetic its untrue.I need to get a new front end from the forks down.What should i look out for?
The back brake is brilliant.a bit too good if anything.
The rear springs seem very low,is this typical on this model?
Thats all my woes.No hang on...the horn doesnt work unless you hold it.
I live in Rugby by the way,do any other members live locally?

Cheers Pete

:) Hi mate, and a big welcome to the World of the wonderful CB750
   The noises you describe from your engine are all quite normal for
   a CB750 remember the engine design is almost 40 years old so
   leave well alone inc the clutch its bullit proof if a little noisy!
   Camchain adjustment is an easy fix as another memer on here has
   already said in an earlier reply If the springs are low on the rear
   they sound as if they are worn out (if they are the originals they
   prob will be) bin them for aftermarket ones Hagons are good if a
   little expensive or try ebay but be careful I use the USA one as  it
   has tons of CB750 bits. Is your K7 the one with the small back wheel
   if its a USA Spec one?
   Front brake performance can be improved at low cost without changing
   the front end give the caliper a good going over inc the swinging pivot
   as this is the cause of many a CB750s brake problem while your at it
   bin the old rubber flexi brake pipe that will also be past its sell by date
   try a braided hose ,bin the old brake fluid fit some decent brake pads
   \"not cheap nasty ones made from recycled cornflake packets\"
    put it all back together carefully & it should work a whole lot better
    but if your used to riding new type Rice Rocketships its never going to
    seem very good.
    Horn sounds like a bad contact at the button WD40 it first mine is also
    on the blink at the button so I reserve judgement till I check it out
    I,m in not so sunny Nottingham regards Asimo :)

I found a good write up on sohc4 site.it is easy on the 750....d`oh!
Camchain is loads quieter now thanks.
It also said that carb balance will make tha clutch rattle,i think my carbs need balancing coz im stripping the bike down and i started it after taking the airbox off and its a lot quieter.
I definitely want dual brakes,i ride a Triumph Daytona Super3 & its got 6 pot`s on it,man what a difference!
I need to start a new thread as i want to do a CR750 job on mine & i want to know the best place(cheapest) to buy tank,seat unit,fairing etc.
Cheers for letting me know alls normal Asimo,much appreciated
