long term ir plug
01/20/10 at 12:43:20

Put a NGK Iridium dpr8eix-9 in the '95 a couple years ago and after 7 or 8k miles it's got to go. At this point the '95 Savage is an intermittent use bike as I no longer use it for a 50-100 mile daily commute. This intermittent use seems to have taken it’s toll on this hi-tech plug. You can see where a ring formed just below the electrode or that part of the insulator melted. This causes the plug to foul out very easily – the last standard NGK dpr8ea-9 went too many miles to count – from this one example I’d have to conclude they’re simply not worth the money – and given the nature of my use of this bike very likely not as good as the cheapest heavy electrode plugs.

That's the reason to run the IR type.

Of late I've only used the '95 for short runs to store say, couple miles at most so it really never gets a chance to fully warm up - many cold starts vs. the long daily runs. What i need to do is migrate it to the fishing shack - the tw200 lives in the new shed but it's easy to ride up the ramp not so sure about the savage it might be low enough to rub on the top of ramp - that could sure ruin your day if it hit bottom - a 4 foot fall off the ramp and out the door wouldn't be any fun.

back to the plug I just don't believe these hitech ir plugs function very well used like this - likely they're better suited to high rpms where their lower arc voltage could be helpful - wouldn't take the ing as long to recover and longer runs to keep the cold start soot burned off.

any way poped one of champions in it that I used for plug reading - man does it ever start and run better.

Ahhh, length of run, not time between runs. I can see that a lot easier.

A 4' drop isnt much of a big deal, if a guy gets to walk to the edge & hop off, but getting "spit" off sideways with a motorsickel atween the legs? Ehhhh, thats a Long 4 feet.
