CB750 / Re: Easing back rear brake pistons - without doing damage.
« on: May 21, 2009, 06:25:46 PM »
1) Right hand 'tell-tale' indicatior light not working. :-[

2) Brand new, fitted by renowned bike Garage, front tyre not correctly seated on rim ???

Failed.

Ho diddly dee....hopefully back in again tomorrow.  Worth the hassle for the "first" proper ride.  Did think it was bit pogo'ish at the front, but then again, new to the bike & my old side valve does that anyway !  Hadn't noticed the t/t light.....more interested i whether the actual indicators worked !......live & learn.

Engine ran very well - which is the main thing.....well pleased, clutch as smooth as silk. ;D

Cheers both, re-fitted & bled through.  I need to get her in 'test' so I can road run her & tweak her whilst managing the tidying up....otherwise she'll sit in the garden & that's not much good :-[

Have managed to get a late notice appointment for this afternoon....fingers x'd ;)

....& the answer is.....take off the rear caliper assy, apply clamp, clean up & replace. 
Ho hum.

I can't imagine I'm the first to find this tricky. I'm about putting new pads in the rear brake on the F1.  I expected, because I knew no better ::) - that the 'contact face' of the piston would be flat......but as far as I can see in the dark recesses it's hollow ?? & it's just the outer "rim" which presses on the back of the pads ? either that or the pistons are stuck in the chambers & I can't see any piston  :o
The 'old' pads were pretty 'thin' & there was well short of the necessary gap to drop the new pads in.  I've been able to get the 'outer' of the two gaps increased - hopefully by retracting the piston rather than bending the disc, the piston did seem to "give" a bit but the inner one is a bu**er.
Just a matter of patience & application ???.......or is there a trick......the front one, which is now working took three elephants standing on it to retract it - I can't see me getting that sort of 'wellie' onto the back one & hope I haven't got to break the whole rear end down just to change a pad. :-\
Needless to say, the Manual says' "remove old pads & replace with new" - & I'm more used to brake shoes  ;)

Not much help, I guess, I've just taken the carb set which came with the bike off.....a Kawasaki Keihn CV set up I think ? & replaced it with the original set.   I didn't really have a guide & through trial & error ended up with the 'pull' cable to the left of the headstock (sitting on the tank) & the 'push' cable to the right, both running parallel to the centre bar....I was surprised at the 'resistance' on the slide set up compared to the previous diaphraghm (sp?) rig.

Mind you, I haven't actually ridden it anywhere yet ! just sitting, taking down & tweaking & prepping for Test.

"Is that your workshop?"

Sadly, no, that's the workshop of the guy who got talked into 'hosting' it when the chap put it up for sale.

a link perhaps, then folks can avoid them if they've just eaten or are considering new decor for the lounge ? ;)

Hello, to all, a new CB750 owner & Forum member.  I've just had an 'evloution' or to be more to the point, revolution in the Garage, with two Hinckley Bonnies & an a 1950's 'lunker' going out & a couple of 1989 Hondas, both 'mint', a VTR250 &  CB-1 coming in to replace them.  Downsizing in cc's, weight & size.  So, to compensate, I've brought in a 1976 (reg'd1978) CB750F.  The VTR's the wifes bike, the CB-1 mine for when I need 'waking up' a bit.

The CB750's only had a couple of owners from new, the first for her first year & the second from 1979 until now.  She's always been looked after - she's been out on loan to nephews & son-in laws of the owner so she's clocked up 32k miles, but they're a family of motorcycle racers & engineers, so she's mechanically pretty sound.  I've just 'un-done' the 1980's 'revision' of fitting CVK carbs, presumably from a Kawasaki as this was,  I gather a 'done thing' ?  She came with her original carbs & they're now fitted & she's running as sweet a a nut.  She's got her original exhaust & silencer too.....pipes are 7/10 for condition, exhaust is 8.5/10.......+ an original Paul Dunstall silencer & a full Motad system, which is currently on the bike, BUT I reckon I'll put her back to 'spec' as soon as I can - including swopping the 'go faster' finned covers which she has all over her.  All the originals - except the round 'inner' generator cover- are with her, thankfully.

She's "brake pads" away from an MOT....she had one done two years ago, but was never ridden after it as the owner at 71, found her too heavy to hold up !!

The only real 'downside' & in some ways it shouldn't be, is that she was given a "proper" Custom paint job back in 1978 - & she's still got it.  She looks like a Tarts Handbag.....but at least she sounds like a sewing machine !

Looking forward to getting to grips with her & hopefully get & keep her "right".  She's too good, in her present condition, paint aesthetics excepted, to do too much to, so I'm aiming to keep the overall patina rather than "do her up".....but need to find a tank & 'tail' !
