I would like to replace the HT leads to the two coils on the 1200 as they are rather old and brittle,but is it possible as they are glued in at the coil ends?

You can replace the leads on the ND coils, there is a brass spike inside that pushes into the new cable but you will have to re-bond the ends. Better bet is fitting a pair of TEKs, KP08 and KP03 the fit into the original mounting plates and use screw in terminations. Plenty about on ebay or I have a good stock.

Replacing Nippon Denso High Tension ( HT ) connector wires.
updated 5th January 2004 IIS
Nippon Denso Ignition Coil High tension lead replacement ( Pinky, biege colour ) stamped 028700
There is an epoxy resin around the HT cable entry point on the body of the ND coil which can be carefully removed by use of small side cutters.
Take care not to damage the body plastic.
There is two parts to the HT lead, the inner HT lead/copper wire with insulation cover and an outside thin sheath. Pull hard on the HT lead until it comes out of the coil body tube, this will leave the outer sheath still inside the coil tube. By carefully pushing a screw driver down between the sleeve and inner bore of the tube until you feel the remaining epoxy break its bond, continue working around the sleeve until it frees from the bore. There is a standard spike termination at the end of the bore.
A good quality copper core HT lead of 7m/m diameter ( 8 m/m will not fit in the bore ) can then be inserted into the bore ( tube) until is stops and then a good quality silicon sealent or Epoxy can be used to secure the new HT lead to the ignition coil body, try not to use building grade silicon as it cures by liberation of acetic acid which attacks copper components.
Use 738RTV if you can find it at the local electrical wholsalers, or at least neutral cure silicon which is becoming more available from hardware stores.
Once done use NGK spark plug covers with 5.0K ohm supression resistor to terminate the HT leads for clean firing of the spark plugs.

Out of interest if I go TEKs Keith, what of the ballast resisters? I put some compatible TEKS on the Sprint (instead of those Motoplatts) but it didn"t have them

You mean the "anti start" resistors, feed them to the mice, the ones with metal teeth...
FWIW, my preference on 180 equipped bikes is to use twin tower TEK's for both coils and frame the centre cylinder spare tower. You can then swap coils if a suspect coil occurs. Not a real problem to use single and twin coils as Keith mentions.
There is a version of the IIS that runs 3 separate coils for the 3 cylinders. Don't promote it much as 2 coils work well on the 180's, besides if there is a problem on one or between the two outside cylinders then ignition can be ruled out. Very useful at times.
HTH, John.

Why do you use a KP08 and not a KP02?

Hi LJ
You find this on Laverdamania :

Hello Xavier,
Could be in many places that description for ND ignition coil service, i wrote it in the first place, ie original author, for IIS users and anyone else that could use the information
. Regards John.
*** The post i did previously was from the original document on file here, suppose over time and copy/pasting the Header was deleted suppose?

Teks are actually KP03 (single) and MP-08 (double)

I'm not an expert but it seems that the KP-02 was used on a CDI equipped Kawasaki. This may mean that it can't sustain running permanently saturated without overheating. Unlikely to be an issue with any of the replacement ignition systems available for Laverda. You may find it a little shorter (80mm) than the MP-08. Both are twin output coils.

The KP02 seems to be used on many of Gpz Kawasakis ie 600,750,900,1100

OK restoring the old coils,thanks John,only had to scrap out one,the double coil both came out cleanly together.Just waiting for the silicone to arrive next week.
The wires from them to the binned resistors goes straight on the loom I presume.?
Many thanks Shaun
