easternrider Posted March 24, 2011 #1 Posted March 24, 2011 (edited) I was looking to spark test my plugs while off the bike (84 VR). Outdoor temp has been around -3 to 7C, and I can't get my bike to start. Just did a whole carb overhaul, charged the battery. Plugs have only 3000kms on them. Bike turns over fine, and for long enough before battery too weak, but no start. Took plugs out, and they are wet, so getting gas. Anyway, I have a 10000v transformer, and was wondering if I hooked it up to a plug to see if it is firing, would or could it harm them? Any thoughts Also, would 10000v be enough?

Black Owl Posted March 24, 2011 #2 Posted March 24, 2011 One thing you need to remember is that just because a plug will arc out of a cylinder is no guarantee that it will fire hot enough under pressure in the cylinder. My recommendation would be just to replace them with fresh plugs.
easternrider Posted March 25, 2011 Author #3 Posted March 25, 2011 Yeah, plugs are bad. Did my test, and they are all sparking all over the place. Spark not going to the tip, mostly jumping over to the threads, and bouncing around alot. Anyway, just picked up 4 more. Hope and a prayer they work.
Venturous Randy Posted March 25, 2011 #4 Posted March 25, 2011 If you have not done it in a long time, I suggest you also replace the sparkplug caps. They have a resistor inside that can corrode and do all kinds if things to how it runs and starts. RandyA
easternrider Posted March 25, 2011 Author #5 Posted March 25, 2011 Thanks, wiring is new. Just did this today, 4 new plugs, press start, and boom........motor purrrrrrrrrrrs to life. Took about 10mins to warm up, but sounded good. Finally!! Now all I need is a plate sticker, and I'm mobile:cool10:
