Hello,

I just bought a BME 50 for my GP Patty 25%, and wish to use the Bosche shielded spark plug cap available from ch-ignitions.com (the place who make the ignition unit for the BME). However, on their web page it says that this shielded plug cap is not suitable for the spark plug that shipped with the BME (NGK BPMR6F). They say it is compatible with the NGK BPMR6A.

Question: Can I use the BPMR6A in my engine so I can use this cap, or is it possible to modify the origianl plug, or Bosche cap so they will work together. Somone told me that I can saw the top part off of the metal contact of the plug that came with my BME, and it will then be compatible with the Bosche plug cap. This doesn't quite sit well with me.

Anybody figured out how to use the Bosche shielded cap with the BME 50?

Regards,

Martin.

Spark plugs with the tops cut off are for the ignition caps on the foreign igitions that come with the ZDZ engines...If the thread in the cylinder is 14 mm you can use any resistor plug that fits and screw the Bosch cap onto the end of the wire, and solder the ground strap to the cap....

OK, I don't understand the answer.
My engine uses a WSR 6F.
Will a Bosch Cap work with it?

Yes

I just got a new CH ignition for my
my BME50. He also sent a new RESISTER plug with which is shorter. I was having interference problems with the original cap that came with the engine. This solved my problem at a cost of $145.00
