Took my 1995 carbed SP for it's first longish run today after changing the plugs to NGKD8EA ..all went well & for an old bike she's quite feisty!!
But when creeping back into town & into heavy traffic after a 100Km easy but spirited run the exhaust started to splutter & pop a little @ idle in the traffic ..Doesn't seem to affect the performance whilst riding above idle revs but it's kinda annoying & disconcerting as if its gonna stall..
So i pulled into a garage & filled the tank (took 14 litres) so as to eliminate fuel shortage from the equation ..didn't see a reserve light come on prior but i reckon i must have been close to that point..So back at home i pulled the plugs & they looked alright ..(a bit blackish sooty but what i'm used to seeing ) popped them back in & it was still popping & farting idling ..So just as an afterthought i popped the old NGK DPR6EA-9 's back in & Voila" no popping!!!
Now maybe it's just a coincidence & i'll take the bike for a run tomorrow & see but has anyone ever had a problem with dodgy plugs in particular the NGKD8EA's? Should i throw in a set of Iriduim plugs & eliminate plugs from the equation so i can continue to troubleshoot if the problems still there ?
Also what are the troubleshooting tips if she's still being difficult & popping & spluttering? The bike's previous owner sold it due to illness so it wasn't ridden regularly of late although he assures me it was started @ least regularly..It's got the standard mikuni carbs & Staintune pipes with the restrictors removed..belts & shims were done approx 1000kms / 8 months ago...
Cheers
