I've replace with Nology.
Been running fine, until I decided to try and make the coil/plug wires more water proof. When I ride in the rain (heavy) I guess water gets under the tank and one of the cylinder misses. I can actually look under the tank and see the spark shorting to the frame or somewhere like that. So as a project I took off all the coils and put a bicycle innertube to cover the length of plug wire. After I put it all back together, I was missing on one cylinder, intermittently. I redid everything and now it runs fine, but still I noticed a very slight stumble a few time on my 30 minute ride. I think it has to do with a break in the plug wire, that's why I want to replace them, without buying it from Triumph.
Anyone know if you can slide the clip inside the sparkplug boot out???
Anyone else have this shorting issue when riding in rain. Another think I noticed is the metal angle for the throttle cable that goes to the carbs is right between the coils for cylinder 2&3, which also touches the frame. I have aftermarket Flatslide carbs, don't know if this is an issue with OEM carbs and I am not the original owner of this bike. I put some tape on the frame where the metal cable housing touches the frame, possibly this is where the arching is occuring, from coil to nearby metal housing to frame??
Anyways, if there's a way to replace the plug wires without getting all new boots from Triumph I will do so as wire is cheap and probably a good maintence item as I've pulled quite a few time so far with owning this bike.....
