CB500/550 / Re: Charging issue! Help please
« on: June 25, 2017, 05:19:12 PM »
Thanks Clive, sadly all my connectors are in tact! 😩

Has anyone else successfully used a David Silver Spares  combined reg/rec?
Be interested to know if I'm wiring it up right?

Also noticed I'm blowing the main 15amp fuse!!
With everything connected up right except the reg/rec, turn ignition on fuses stay in tact.. when connecting the main block connector for the reg/rec, turn ignition on, fuses stay in tact, as soon as I connect that black/red wire to the black and white of the old regulator fuse blows!

This is becoming very annoying!!

Hmmm interesting,

I've tested the combined reg/rec I purchased which is fine although I have always questioned if it was the correct combined reg/Rex for my bike. I will post a pic of it soon.
It has..
3x yellow
1x red
1x green

I believe these plug straight j to the harness and seem to match up colour wise.

It also has 1 x black/red stripe wire which forks into 2 spade connectors. The fitting instructions state to place these spade connectors, one into the black wire of the old regulator and the other into the white wire if the old regulator and discard the green wire from the old regulator?
It just doesn't seem right to me??

The thoughts of your minds in this one would be very appreciated!!

Thanks again
Alan

Hi everyone,

Just a quick one I'm in the process of testing all the components involved in charging the battery, reg/rec, stator field coils, rotar etc

When testing the resistance in the stator field coil it reads 1.3ohms minus the resistance between the probes (0.4ohms) This would make 0.9 ohms!!
Manual states .35ohms plus or minus 10% therefore if I am correct the maximum resistance should be 0.39 ohms and my readings are all 0.9 ohms!!

Can anyone tell me if my readings would mean the coil is knackered or will it just not charge properly??
I can't seem to find anything else wrong with the system at present!!

Thanks

Alan

It's not thermal imaging just a temperature IR gun. Point it with the laser at parts of the engine and it gives a temp!

Still waiting for temp gun but this is how hot it gets...

Rocker cover, head fins, points cover, stator cover all are untouchable! I mean even if I was to touch them for a fraction of a second I would leave my skin on them!
This is after a 20 minute run light to moderate traffic uk!

Checked my cam and it may have been one tooth out, this has been adjusted l, valve clearances re done, static timing bang on, 40 idle 115 mains needle on 3rd notch!

Ordered a temp gun! I'm hoping it's just me being paranoid! Can anyone tell me if they are able to touch parts of their engines after a ride out! The rocker cover is untouchable as in scalding hot!
Going to check cam timing as I think it's the last thing which could be causing this issue!

Thanks for all ur help

Thanks again!

I just feel like putting bigger jets than 115's in will be over compensating for something else? Think I'm going to check all the other things that could effect the leanness first!
I did a top end rebuild on this and wondering if maybe the cam is a tooth out? Would this cause it to run lean? I assume it wouldn't pick up like it does and allow me to staticly time it if the cam was out?
Went to the bikeshedmc show in London at the weekend and really inspired! Just want to sort this issue out now so I can take my project for a ride further than the end of my road! 😡😡😡😡

Thanks

Ignition timing is spot on when testing in the static method..  should I throw a timing light on it?
To richen it any more would mean upping the jets to 120's 125's and I've never heard of any cb550f requiring any bigger than 115's???

Thanks Al

I have a CB550F running 4 - 1 with pods! (Yes I know pods)
I have 40 pilots and 115's mains and needle clip 3rd down.
It runs really good, idles fine and picks up well through the range and doesn't back fire!
My problem is it gets very hot!!! I cannot touch the rocker cover after a short ride and if I spit on it it frys it straight away! Now I don't know how hot these engines are supposed to get and I may be paranoid but it doesn't feel right to me. The points cover stator covers everything to hot to touch!
It may be running slightly lean as the plugs are slightly white but can't believe I'd be putting bigger jets than the what I have! Timing fine too!!
I also have the exhaust headers wrapped in heat tape!!

Any ideas please??

Turns out having taken the bowls off today that he has put #38 idles jets in and #98 mains jets in!!!

Sadly I have de tabbed the bike as part of the project so can no longer reserve and put stock air intake back on! I assume you can run these carbs on the 550?!

Phil they are the 627b carbs! Even though it's a pain to change the needle clip I can can do it! I do have 105, 110 and 115 main jets for the 069a's which came off the bike. If I changed the main jet would needle adjustment still be required?
It's not idleing that I'm having issues with and I thought the idle jet would be the one which needed changing not the mains?
