Agree with bryanj, had this discussion with the D Silver bunch, after they sent me D8Es plugs for my 400/4, maybe OK for unsupressed metal caps, but my local Honda dealer recommended D8EA plugs for use with the more modern suppressed plastic caps, that was 1985, never had any spark trouble even in the wet with them, I think the above were a set of freebies from a breakers!

thought the resister plugs had a suffix "R"
Ashdowner:
Why is life so complicated. How do I tell if I have resistor caps?
ka-ja:
Hi John, apologies, plugs sent by D Silver were DR8ES-L, anybody want a set of 4 cheap! NGK recommended plugs are not resistance type plugs
Ashdowner---Apart from plug type/number, NGK also have "R" printed under the NGK logo. Float level with clear tube probably involves fitting a modified drain plug under the float chamber to fit a level tube on? maybe wrong,I've never needed to do it! ---Ken

Final comment - I've checked and I have 5K Ohm NGK -plug caps on the bike. I found a previous thread on the subject that says you should use resistor plugs with NGK 5K caps i.e. DR7ES which is what I have, and it's probably why David Silver and Wemoto etc list them as the standard plug for the K3.

I believe if you use the resister plug caps,you NEVER use resister plugs as well!!
