Hey guys, I have a SIP digital speedometer and it's causing me problems. After a few minutes of running it generally freezes up , the Rev counter won't work and CHT stops etc, have just read somewhere on SIP forums that you need to change to an R-type spark plug, this has a built in resistor which suprsses engine noise that causes electrical problems so will post the results after I've got hold of one.

I can confirm that I have fitted an R-rates plug : BR8HS, I have done around 50 miles on this plug and the speedo is working fine, hasn't frozen up once, hope this helps.

You won't believe this but over the weekend my CHT sensor has stopped working, probably a cable snapped somewhere, have an idea that it could be a cable in the headset that's broken...Fixit On Repair Daily as some might say or FORD!
