Apparently been glued so many times it’s now bunged up and needs a more permanent repair. Obviously another float bowl with fox it but finding one is like hens Teeth

Hi all, got a set of carbs here for a gsxr750L and one of the plastic pipe unions on the float bowl has broken as per the image. any idea what I can do to fix this ?

Interchangeability of carbs and carb rubbers for oil-cooled engines

Thanks for the reply - just to be clear it’s the 750 L carbs going on a 750K thanks -

Sorry if this has already been covered (couldn’t find it) but can carbs from an L model be used in a K model ? -
Checked sealing by spraying wd40 over rubbers which had no effect.
-
The engine was cold on the compression test. Throttle was closed.
-
Ok carbs are off, I’ll strip em asap and let’s see. incidentally this bike only has 31k miles on her.

Not quite - the problems continue

Evening all. I picked up a 1989 750 K non starter that had been laid up for some years. I found it had no spark which turned out to be the CDI unit. Replaced it and got her to start but she will only run on 3, pot 3 being the naughty one. occasionally pot 3 comes in but it’s intermittent. I see fuel coming out of the carb breather tube as a dribble. she will start and run on choke but turn the throttle and she dies. Once warm on choke I can start her without choke but the throttle has to be wide open to get a start. I can keep her running if I good the throttle partially open but she does if I drop to idle speed. I did a compression test but I’m not 100% happy with the fitting of the tester - the adapter kind of wobbles in the plug hole. Pots 1 2 and 4 give around 100psi pot 3 gives a very low PSI reading. I was kind of hoping that it was a tester issue or stuck valve that would free up with some running of the engine. I have not yet repeated the test since having run her up. here is a video of her https://youtu.be/R4TaK2QD5cw I’ve taken the carbs off to clean them but would value some help on whether this could be a carb issue or something else. thanks in advance

Hi Tony - sussed it out - no pulse from CDI so tried another CDI - got spark. Many thanks !

Hi all, good thread. I’m having similar issues on my 1989 GSXR750. when connecting a test bulb to the coil wires - no pulse. Change CDI to a spare and then get a pulse ok but still no spark. testing resistance on the pickup wire is 171 ohms when not cranking and flickering open circuit when cranking. No resistance. I do have 12v on orange at the coil. All wires between coil and cdi have continuity. B/W to chassis is 0.3 ohms. so is the open circuit while cranking at the pickup connectors pointing to the pickup being faulty ?

Interesting - there is little or no reason other than cosmetics to pull it appart. Its quite oxidised in places and I was under the impression that to clean it or vapour blast it I would need to strip it down ? I'll get some close ups and see what you think
-
Thanks all - useful info. The RAL7021 looks promising. Looks like its best to pull the mototr - fully tear it down and get it vapour blasted depending on the cost

Just embarking on a 750L restoration project and am also researching paint available in the UK for the engine but I would like the stock grey colour. the ones discussed in say what now!?.com are all USA so cant get them here so would appreciate any suggestions. I gather complete engine dissassembly is required to do this right. What / how had people prepped the engines with ? I was considering vapour or bead plasting ?
