CB750 / Carb sync tool hose length

Just curious.....when syncing the carbs with a vacuum sync tool, do the 4 hoses need to be the same length?

Cheers

Hi Simon, thanks for the offer but I have the "single post" taillight.  The fender I have has the mounting holes for the larger light, like yours.  No need to dig the fender out!
Cheers, Andy

Looking for a rear fender (the chrome one) for a CB750K1.
I realise it's a long shot, but if anyone has one in very good to excellent condition I'm prepared to pay fair price and shipping to Western Australia.
TIA.

Came across this cover while rummaging thru my spare parts bin.
Can anyone tell me which bike/bikes it would fit?
TIA

CB750 / Re: Rough running CB750K1
« on: March 30, 2022, 11:22:28 AM »
Andy,  I have a K1.  I have found that a small air leak on the exhaust adapters can influence idle.  Like you have been chasing my tail getting smooth idle and sweet acceleration. The PO hadn't used any sealant where the headers fit on to the flanged adapters.  I pulled the pipes and used a small amount black high temperature silicone.  The idle is transformed, but I haven't been out for a test ride yet.

Good luck

Cheers,

Jerry

Thanks for the info Jerry!  Have you been able to get out for a ride yet or is it a tad too chilly in Suffolk!
Still high 20s/lo 30s Celsius here in Perth!
I'll be removing the exhausts over the next few days and will have a close look for any leak indications.

Cheers
Andy

CB750 / Rough running CB750K1
« on: March 22, 2022, 09:30:23 AM »
Hi Folks,  I recently acquired a nice American import K1.  However, it was running poorly...idling too high, seeming to miss and carry on under throttle etc.  The bike is completely stock, including the 4 into 4 exhaust.

So an initial check revealed a faulty plug cap on #3 cylinder.  After replacing same, the bike still ran poorly.  So I took off the carbs and gave them a full clean (removed and cleaned all brass, ultrasonic clean of carb bodies, slides.)  Reinstalled brass, set float levels (all were out!) and carried out a bench sync.  I also replaced the rubber "insulators" beween carbs and head.  Then I checked and adjusted tappet clearances (they were close to correct).  Primary and secondary coil resistances were checked and were in spec (4.5Ω/14.5kΩ).
Before vacuum sync, I checked that the points timing was correct...it was.  Carbs then reinstalled along with stock airbox and filter.
I proceeded to vacuum sync, and although the sync tool (Syncroking 4 MkII) indicated full carb balance at idle, it still ran a little "lumpy".

Increasing throttle opening still showed very good vacuum balance but bike still didn't sound or feel right.  I double-checked my procedures and compared the Syncroking with a mercury manometer.  Both indicated the same good result.
So I popped the tank back on and went for a quick ride, and it proved that something was not quite right....it felt lumpy unless throttle was cranked open.  Closing the throttle brought the bike back to normal idle, again a little lumpy however.

Sorry for the long ramble but I'm at a loss as to what could still be causing such "rough" running.
There are many on this forum far more experienced than I so I'm hoping someone may have an aswer for me.
Thanks in advance!

CB500/550 / Re: CB500K1 front brake stop switch

Fraid not, as soon as you remove the old switch it will allow air into the system, try clamping the pipe above the junction to stop the fluid draining down from the master cylinder as that will make bleeding the system afterwards much easier.

Thanks.

OK so DSS were able to source a genuine replacement from their US store, which arrived yesterday.
Is there a way to replace the faulty switch without having to completely drain the brake fluid?

CB500/550 / CB500K1 front brake stop switch
« on: December 12, 2020, 10:17:07 AM »
Hi folks, it appears the subject switch on my K1 has packed it in!   :(
DSS et al apparently don't have any in stock.
Can the switches be refurbished in any way?

CB500/550 / Re: Delkevic exhaust system
« on: May 28, 2020, 11:27:06 AM »
Topic is old, but I've just fitted a Delkevic to my 500K1.
Arrived here in Perth from Queensland in 9 days, which was pretty good in this current climate!
I was very impressed with the packaging for starters....muffler in its own styrofoam box and all pipes, collector, ancillaries well wrapped in bubblewrap. 
It almost took me as long to unwrap everything as it did to fit the system up!  (Not really)!  ;D
Quality, no-hassle fitment, good instructions.
Sound good too, a bit louder than the system I removed but not annoyingly so.
I'm a happy little Vegemite!  8) :P ;D

Unfortunately we're moving into a wet Winter so taking the bike out will be a tad problematic.  We can go out though, as Covid restrictions in WA have been relaxed somewhat.  Next week looks a bit more promising.
Stay safe everyone!  :)
