CB500/550 / What is the correct 500 rear brake light switch wiring route ?

« on: Today at 05:01:40 PM »

I can't seem to see the best route for the brake lamp switch wiring here is my photo.
Not sure if this would interfere with the fitting of the side panel.

Does anyone have a photo of the correct wiring route?

The cable tie is temporary, iginition currently disconnected whilst I'm doing the static timing.

CB500/550 / Side stand too close to the number one front pipe issue ?

« on: Today at 04:25:38 PM »

My side stand when it is in the up position is pretty much touching the front pipe on number one cylinder.
As my bike had a 4:1 system it was not an issue on the old silencer.

Before I look at trying to move the exhuast a tad is there any other possible explaination?

The Delkevic system comes with a large single rubber grommet what is this for?
There is a square rubber fitted for the centre stand.

Initially I plan to retain the standard points system then change over to electronic ignition if the bike runs ok again.

It must have taken me an hour of checking the points gap, checking the F mark for the bulb to light up in the hope that my static timing is good enough on 1/4 & 2/3 can't believe how rusty I am at setting points. I will use my strobe when it's running.

It would be great if the two small pegs for opening the points with a screwdriver were even close to the recess on the other side of the contact breaker.
Presumably I could move the backing section to achieve this. I assume some of this is linked to the brand of ponts fitted as well. There is no pitting on the contacts they look very new in terms of use.

We can all make mistakes - some are just not honest enough to own up for fear of looking foolish.

I famously rode my 400 on two cylinders on several journeys of popping & banging as I had the plug leads on wrong.

My late father told me that the only people never make a mistakes - never do anything.

I have a theory Julie that the issue on the left side upper exhaust might have been related to the rear foot peg bracket end angled section just looking very slightly different on the bolt hole end section from the right side. I suspected wrongly that the right side was slightly mis-shapen due to the previous 4:1 system fitting.

The one on the right side that fitted perfectly had a distinctive angle at the tip, the left side hanger was not a mirror image - it was visually slightly different a smoother curve.

One advantage for me was by fitting the bracket to the upper exhaust in situ with the balancer pipe connected I could see where the bolt need to align with the bracket when I slipped it in place. This meant I only needed to file it once as I could see where the slotted hole needed fettling. I did not need to elongate the angled slot just take a small amount of metal from the middle top of the slot.

Nicely phrased Mick - when I look back at your starting point it's brilliant work you have done on what was definitely a dead bike, the CB 500 lovely bike , that bike was no more, it had ceased to be, destined for that bike yard in the sky.

Presumably you have actually counted the teeth on the front sprocket as well or is it stamped on it?
One tooth more makes a big differance.
Does your new chain sit fully on the sprockets as it should?

Otherwise I'm stumped

It's either the wrong chain if it's like that or the front or rear sprocket don't have the right number if teeth.

I use a cable tie to pull the ends together then pop in the link.

I removed the left side top silencer, loosened the clamps on number two front pipe to find a nice stress free position. Lightly nipped up the clamp on number two port.
I removed the bracket from the upper silencer then re-fitted it as previously. When re-attaching the bracket I could see that the top slot needed a little opening up at the top of the slot to allow the upper exhaust to drop down a tad. A small amount seems to make a difference at the tail pipe end. It all went together well except when clamping the hanger bracket it wanted to pull out of the balancer joint. The Delkevic top bracket has a half circle reinforcing plate attached to the bracket. If I fully tighten the hangar bolt it starts to tip the rear of the silencer.

I'm chewing over the options - might try and fit a sawn in half washer to keep it all flat at the same angle .

Update Just used a slightly thicker stainless washer that has a slight dished shape, fully tightened the nut on the bracket all stayed in place.

Dave I have a small auxiliary petrol tank so if all goes to plan I might go for a first start up next week. Not checked the timing yet but it's a real possibility.👍👍👍
