There's a small 2 pin diode/rectifier thing is that what you mean?
The loom is for a 78 from David Silver and Switch is a replica of the Original with the Starter button and Red kill at the top and the Headlight modes. If that's any help at all 18

Fair enough I might just take a punt on a new one tbh as I need it sorted out.
Another question, I installed the new wiring loom but for some reason I can't get the Starter button to work. I don't have a neutral switch or clutch switch and think that's the problem, do they need earthing or? Thanks again 19

So, with the Ignition on and bike not started.
All earth's seem perfect, All the same readings there. Then Mulitimeter on battery Negative, Solenoid perfect, fuses perfect both ends, all red wires in and around battery all good. Then, Battery: 12.7 Key switch Red in : 12.0 Black Out: 11.8 If I unplug the Keyswitch, Battery is 12.7 and Red in Plug at Keyswitch is 12.6 20

Still having issues. The Black wire that goes into the Reg Rec is reading roughly 1v under what the battery says. Is this correct or should it not be basically the same as the battery voltage? I'm scared of over charging basically

Guys,
Having problems with my electrics, basically the new solid state Reg Rec i fitted, on the Black wire coming back into it is showing 1v Less than the Battery, therefore its telling the rectifier that the battery needs charging more when it really maybe doesn't. Ill list what I have changed, 1) New Loom 2) New Fuse Box 3) New Coils 4) Dynatek Ignition in place of Points 5) New Hand Controls both sides 6) New lithium Battery I've been through everything, earths, everything being wired properly, the stator everything! I came to the Conclusion last night, that it's the Dynatek drawing the extra power because if I unplug it the 1v appears on the Black wire again. I basically have to Run a new Black or Splice into the System before the White & Black that goes to the Coils that the Dynatek Connects to, has anyone got any idea where i could do this? Rear light or horn maybe? The White and Black goes the the RH Switch which is Connected to Black as well. I just don't want to Ruin a new Battery or anything else, so any suggestions at all would be appreciated! 23
CB500/550 / Re: Hard Starting when Warm« on: September 24, 2018, 11:21:16 AM »550 with choke cable! Would it be a K3 with PD carbs? If so they are a swine to get right on standard setup never mind with the alterations you have made. I suspect bigger pilot jets may help as those carbs are set to run very lean and your mods have made it leaner, trouble is they are press in jets and not readily available. Only place i know is Sirius in Canada and they do very few sizes That's the very one!! Tbh, I'd nearly go as far as saying it's maybe too rich. It's very Dark Brown. That's after a good run and slow down with clutch in and plug out. There's absolutely no white on any plug at all. Maybe pull the needle up a clip and try it 24

It starts nearly first time when cold and runs and sounds perfect.
Plugs are a Dark Brown colour when out. It has 4-1 Headers with Pods. I have 110 Jets and down to the 3 nick on Needle. New choke cable too. Plugs only new less than 500 miles ago as are the Leads and Caps 25

Hi guy's,
My CB550 for some reason is very hard to start with the kick or Battery when I've been out a run and then stopped. I have a Dynatek ignition system. Everything is all timed and valves perfect. Anyone any thoughts? I got caught out yesterday and had to trailer it home 26

I just wanted to say Thanks to everyone in this Thread that helped me out with Advice and pointers, links etc.
Massive help 300/400 miles later and it's better than it's ever been! Aaron 27

Anyone got one of the above? 28
CB500/550 / Re: Gearbox« on: April 30, 2018, 09:26:24 PM »That sound will be the ratchet pawls inside the kickstarter gear, it's normal but with the casings on and the engine running you don't hear it. Thought that but just wanted to make 100% sure. Coming along nicely and everything is all Ceramic Coated. Treated myself to a dynatek ignition too 29

Guy's stupid question but I'm asking it anyway.
Engine out being rebuilt atm The Kickstarter shaft etc. We built it but when the chain drive is moving it clicks for want of a better explanation? Is this correct? 30
CB500/550 / Re: Gearbox« on: April 10, 2018, 02:34:18 PM »I'm not sure if a bottom end IS the way to go TBH, there is a lot of damage sure BUT the problem is the new bottom end isn't guaranteed to be any better unless it comes with one of course. TwoWheelSpares on E-Bay have some complete engines but no bottom ends, your never sure on what the crank shells are going to be like on another engine, his may be new but they don't transfer as we know unless your really really lucky. Oddjob this one!! Lol so thanks. Yes both sealed and bearings sitting correctly too. Yes but it's all a part of the learning process. I'll know all this for again and so will my Dad. Dry run with the Gearbox in last night and it's engaging perfectly. I noticed a slight twist in the Gear Change rod, specifically on the end that has the fork where the clutch is so I ordered a new one of them. |
