I have been using an Iridium plug for the past 3000 Kms and they are just brilliant.

Hi , the E means its a resistor plug,

I 'm not sure if the older bikes need a resistor plug?,

check with a dealer for clarification,or the Czech on line manuals..

the E plugs are quite unusual, husky and Norton rotary apparently..,

hope this helps,

Charlie

my 2stroke was doing the same and no, iridium does not helps.

for me helped a higher heat range egfrom 9 to 8 and from that time i'm using the same simple B8ES plug

i think you should check your jetting(mine is running rich)

What do you mean by blowing plugs? If they are wet your to rich and need to work on jetting. history of bike? has it always done this or something it started doing after a while? Does it run fine until the plug issue?

Hi , the E means its a resistor plug,

I beg to differ on that.

The 'E' on the end of the plug designation means "extended nose."

The R it the CR8 means its a resistor plug.

For a full explanation of what all the letters and numbers mean on a spark plug, have a look at: http://www.ngksparkplugs.com/tech_support/spark_plugs/faqs/faqcode.asp?mode=nml

Hi sorry ,

yes thats what i meant to say..,

the later huskies were unusual in needing a resistor plug,

as convention says the resistor is elsewhere in the circuit,

as the mans bike has a replacement ignition system , he may not need a resistor plug

hope that makes more sense,

Charlie
