BallabioJoj Posted March 18 Share Posted March 18 Dear V11'ers. Long time no posting, but still riding my beloved V11 Sport Ballabio here near the Black Forest in SW Germany. I changed the plugs and the left cylinder HT lead cap fits on the little screw on spark plug nipple, but the right lead only fitted if the small nipple was unscrewed from teh new plug - directly onto the threaded plug end. The right lead is now too loose for safety. I guess the leads should be replaced as a pair? anyone know a part no or recommended brand? what is the connector on the other end? Is this an easy job if I lift the fuel tank or best left to the dealer? thanks for any help/advice; keep the rubber side down. 1 Link to comment Share on other sites More sharing options...
GuzziMoto Posted March 18 Share Posted March 18 You may be able to bend the connection that is supposed to go onto the sparkplug to get it to fit. It is just a metal fitting crimped on the end of the wire. It may have been squished or otherwise bent so it no longer fits. Just bend it back. That should make it work. If you can't bend the end to get it to fit on the spark plug, you could cut the old end off and install a new end on the stock cable. Being less then an inch shorter should make little difference. As to replacing the spark plug cables in pairs, that doesn't seem important to me. As long as the cables are the right type, and the same type, it should make little difference. 1 Link to comment Share on other sites More sharing options...

Plug caps for plug threaded collar on and plug threaded collar off are two different designs. Collar on plug lead cap has a formed sheet metal internal split sleeve that clips over the spark plug collar and the type that is designed to be used with the plug collar removed uses a machined plug cap internal metal fitting with a spring wire designed to provide the connection and holding friction for the cap. The OP may have 2 different styles of caps fitted. Time to just replace them with some new ones. I have the P/N's somewhere. Phil Link to comment Share on other sites More sharing options...
audiomick Posted March 18 Share Posted March 18 I had a bit of a look. First of all, I would tend to just replace both plug leads and caps. They are old, they age, and they don't get better with age. I went looking at Stein-dinse, Wendel in Berlin, and HMB Moto (kennst Du den schon?). Wendel and SD both have plug leads, but list the original cags as no longer available. Mike at HMB has leads and caps. The leads are cheaper than those at the other two. If I remember rightly, the caps are just screwed on to the leads. Anyone here who knows better, please correct me. The other end of the lead, which has an odd looking sheet brass fitting on it, is just plugged in to the coil. So changing the whole business is no great drama. Here are the parts at HMB: https://hmb-moto.de/Zuendkabel-V11 https://hmb-moto.de/Zuendkerzenstecker-Gummi-rot not "dirt cheap" perhaps, but I think once every 20 years or so is probably affordable. Schöne Grüße aus Leipzig. 1 Link to comment Share on other sites More sharing options...
docc Posted March 18 Share Posted March 18 The caps on the later V11 are NGK 5,000 Ohm resisters. The early V11 are Champion. I get mine from a scooter shop in England. Because they can be damaged (along with the sparkplug) in even a light tip-over, I carry spares in the monkey paw trap. 1 Link to comment Share on other sites More sharing options...

Looks like the same thing to me, just red or black. The inscript "5K Ohm" is visible on the picture of the black one. https://hmb-moto.de/Zuendkerzenstecker-NGK-LB05F-R-rot https://hmb-moto.de/Zuendkerzenstecker-NGK-LB05E Edit: a closer look reveals that Mike apparently perpetrated a typo in the listing. The red one is listed as "LB05F-R", and the black one as "LB05E". In the text body, however, they are referred to as "LB05F-R" and "LB05F" respectively. A look at what appears to be the NGK site turns up these, which are apparently the items in question, and both are 5K Ohm caps. As already mentioned, seemingly the same, except for the colour. https://www.ngkntk.com/de/produktfinder/motorrad/zuendstecker/lb05f-r/ https://www.ngkntk.com/de/produktfinder/motorrad/zuendstecker/lb05f/ 1 Link to comment Share on other sites More sharing options...

Quite relieved to find out there is so much expertise and help still out there for the venerable V11. Getting a RE Himalayan 450 to complement the V11 but it will still be my daily ride and Black Forest tourer. Mine look exactly like the red one's, but I think my leads are integrated into the caps which might have to be cut off? could be just the accumulation of dirt etc after 20 years of the MG living outside on the street. 1 Link to comment Share on other sites More sharing options...

That does exist, for instance these ones from Silent Hektik Quote mit einer hochwertigen Silikon Kabelisolierung, verschweissten Silikon-Kerzenstecker und .... https://www.silent-hektik.de/Zub_Kabel.htm but in the case of the NGK plugs in the link, I'm fairly sure that is not the case. When you are ready to attempt the change, pull the boot back on the cable side of the plug, and try and screw them off. Given that they are going to be changed anyway, there is no great risk in that. The advantage is then, that you know for sure how they are put together. Having said that, cutting the leads back a bit (assuming you don't change them...) to give the new caps a fresh end to join to is probably a good idea. 1 Link to comment Share on other sites More sharing options...
