sp838 Posted March 12, 2015 Share Posted March 12, 2015 don't think the wires go bad Link to comment Share on other sites More sharing options...
docc Posted March 12, 2015 Share Posted March 12, 2015 Still original Docc? Yah, original wires, although I repaired the right connection to the coil some years back (big improvement!) So, gstallons, what to look for in the resistance in the ignition wires? Link to comment Share on other sites More sharing options...
gstallons Posted March 12, 2015 Share Posted March 12, 2015 This is a subjective # but around 5k ohms per ft. is normal for ( as we know them ) spark plug wires . You will be looking for resistance and not infinity or open . Link to comment Share on other sites More sharing options...

Scud Posted March 13, 2015 Share Posted March 13, 2015 On a practical note, the Red caps I referenced earlier arrived today. They fit the plugs just fine, they attach to the wires the same way as the stock ones, they measure 4.8k ohms resistance, and they are about ready to be stuffed under my seat - hopefully for all eternity. But I'm curious now, even though the answer probably won't make any difference to what I do. It's a theoretical question. If the wires have resistance, why does it matter if the caps add a little more resistance? Link to comment Share on other sites More sharing options...

gstallons Posted March 13, 2015 Share Posted March 13, 2015 A spark plug wire this short will not give you the necessary resistance to serve it's purpose. This R will keep the arc time minimal to reduce wear on the center / ground electrodes on your spark plug. Link to comment Share on other sites More sharing options...
Scud Posted March 13, 2015 Share Posted March 13, 2015 @gstallons - your first response made me laugh out loud several times. As William James (Pragmatism) might say: Debate is futile unless a practical difference between alternatives can be demonstrated. (FYI - not a direct quote) I imagine you had to do a little research to find the practical difference for us. Thanks. Link to comment Share on other sites More sharing options...

gstallons Posted March 13, 2015 Share Posted March 13, 2015 I talked to my old electronics instructor / best friend Gerald Wells to verify this ...after one hour of revue and lecture , you get the explanation . We started with copper core " high tension " leads , narrow streets in Germany , burn time , then to spark plug electrode composition and so on .

docc Posted March 19, 2015 Share Posted March 19, 2015 I got my Champion red caps from the UK in ten days. Pretty amazing! Link to comment Share on other sites More sharing options...
czakky Posted March 19, 2015 Author Share Posted March 19, 2015 Finally ordered my black caps via MG cycle. Along with a timing chain tensioner and some gaskets. Finally going to replace my gimpy broken timing cover and see if this tensioner helps my idle smooth out... Btw Moto International has timing covers for around $95 us. They are silver but that's what BBQ paint is for. Link to comment Share on other sites More sharing options...
sp838 Posted March 20, 2015 Share Posted March 20, 2015 I just ordered a couple of these: http://www.amazon.com/gp/product/B0018JUMF0/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Link to comment Share on other sites More sharing options...
czakky Posted March 22, 2015 Author Share Posted March 22, 2015 Neighbor kid was bored so I taught him how to adjust valves on a Guzzi (valuable lesson right...) anyway threw on fresh plugs and started her up. I got a nice reminder of why I need to replace my rashed up res. covers. Didn't know 12v could get so hot! Wow! Link to comment Share on other sites More sharing options...
