Honda-SOHC

I have this problem at work, I fix MRI scanners for a living.
The magnetic field can't simply be turned off so I have a full set of non magnetic Titanium tools.

Horrendously expensive though, 1 spanner is a few hundred quid.

Just getting my CB550 ready for its MOT, noticed that the previous owner has put a 4.25 wide rear tyre on it.

Seems fit ok, haven't ridden the bike yet due to knackered carbs, electrics etc etc.

Is 4.25 too wide?, I will probably be changing tyres soon, should i go for a 4.0?

Will it suffer from water ingress though due to water running along the HT lead?

The old HT lead wasn't secure in the coil housing, it was literally held by the end of the cable. Once the cable was cut it easily pulled out.
The new cable is 7mm and its a perfect fit in the hole. I suppose water could possibly get in but a tiny bit of silicone sealant would stop it.

DOT 5 is hydrophobic.

I thought that was a fear of water 

1) You need, 2 croc clips, wire 100K Ohm resistor, 2 small spade connectors ( to jam in pulse generator connector)
2) Cut the red wire in the middle and solder the resistor in line. Cover completely with tape
3) Attach croc clips to one end of each of the red and black wires (solder or simply crimp with a vice or good pliers). Cover connection with tape
4) Attach spade connectors to other end of each wire. Crimp or solder.
5) Remove bike riders seat (two hex socket bolts)
6) Remove tank securing bolt
7) Remove two tank bracket bolts
Raise tank and wedge something underneath to keep raised.
9) Look for a Red connector that is in a black sheathed line from the top of the clutch cover to the wiring loom that runs parallel with the RHS of the tank. (This is the Ignition Pulse signal wire)
10) Disconnect the red connector. The male end (the two prongs in the connector) has two wires - 1 Yellow and 1 White/Yellow (mine had faded to look mostly white) that run to the loom & onto the ECU
11) I found that I had to squish the female spade connectors a bit in order to get a tight fit on the male connector prongs - a bit of trial and error.
12) Attach the BLACK cable spade to the prong attached to the White/Yellow loom cable and the RED cable spade connector to the prong attached the Yellow loom cable.
13) Make sure your ignition is turned off
13) Attach the red croc clip to the positive + terminal of the battery and the black croc clip to the negative - terminal
14) Put the WORKING key into ignition and turn on
15) The HISS Green LED in tacho face the will come on and stay on
16) Disconnect the red clip from the battery - HISS LED stays on
17) Wait 2 or more seconds - the HISS LED should start flashing four times and repeat this pattern
18) Turn off ignition and remove the WORKING key. The ECU is now in programming mode.
19) Insert your new key (make sure it's one with a transponder in it) and turn on ignition . A pattern of four flashes of the LED means the key has coded! Turn off ignition.
20) You can repeat this process for two more keys (meaning you can have a total of 4 programmed keys).
21) Remove the croc clips and spade connectors and dont forget to re-connect the Ignition Pulse red connector
22) Re-bolt the tank bracket and tank
23) Replace seat and you are done.

I had my car broken into last April. They took a load of my electronic test equipment I use for work.
Few weeks later I saw it on Ebay, even still had my name on it.

Found out that you, as an individual can not report an item to Ebay that you believe to be stolen, It has to come from a law enforcement official.

By the time the Police were involved, it had been sold on and the Police were not interested 

There is a head off a 550 currently on Ebay with the same damage, but only on #2.

Might not be 100% identical but check these out:

I used them on the resto of my 1966 Lambretta LI150, they are very similar to the ones on my CB550

Thanks for the suggestion. Have you found a suitable 'glossy' sleeve to go with them?

The Lambretta didn't need a sleeve, but what about heatshrink?
