i call b.s.!!!!!!

[g3stripes]

fyi my daughter in law bought the ngk iridium racing plug for her buell blast with high hopes of cheap and easy horsepower gains. she brought her blast to me to install new levers,dirtbike bars,new clutch cable and some other minor mods including ngk plug. after taking it off the lift and firing it up my intention was to run it up the street to check clutch adjustment. let out clutch putting bike in load mode it dies thinking a fluke I repeat a number of times with same result,scratch head and think to self bike ran great before, what is dif? plug? no way,36.00 plug crap/ NO WAY! but to follow my simple things first rule I put old plug back in.........surprise buell back to running great! I call b.s.

Could just be a bad plug, seen it happen before.

 

[g3stripes]

still bs they cant test a 36 dollar plug before they place it in the plastic container it comes in,(prob some of the cost) just sayin lol, wonder if Japanese plug is made in china?

 

[Theycallmecrash]

$36?!? What?!

 

[anrkizm95]

could have been dropped at the part store maybe you jacked it up putting it in or maybe its just a bad plug.
shit happens

 

[lotusexcelle]

What how where and why 36 dollars?

 

[go cytocis]

Something certainly doesn't sound right. I really wonder if it's the plug itself. A plug either sparks or it doesn't. A spark is also a spark, at idle or at WOT. Perhaps the friction point changed drastically when you installed the new cable & lever causing the stall until you got used to it???.
Not trying to imply you don't know what you're doing, I just find it hard to believe that a plug which works fine at idle is causing the stall.
Is the new plug gapped?

 

[Matteson]

put plug in cable and touch to case, fire motor. Spark?

 

[jetlee]

It sounds like a bad kickstand switch. Unplug the kickstand switch and jumper the wires to bypass it; or clip them and twist them together.

Check the top of the plug to ensure the screw-on-tip is tight.

NGK Iridium is $36? I call bullshit on THAT.

The Denso Iridium Racing is a $35 plug.

That too.

A spark is also a spark, at idle or at WOT.

Wrong. A weak spark may be strong enough for a small mixture at idle but not strong enough for a WOT mixture.

Is the new plug gapped?

NEVER adjust the gap on a Denso Iridium Racing, you'll damage the anode.

 

[sparky300]

Is it possible you didn't have the plug wire seated all the way when you installed the race plug?

 

[Matteson]

A race plug on a blast

 

[go cytocis]

Wrong. A weak spark may be strong enough for a small mixture at idle but not strong enough for a WOT mixture.

Remember, we're talking about a Blast here. It's not the world's most high-performance engine. I agree with you that on a motor with lots of compression, advance & revs, yes, a weak spark will compromise performance, but it's much less likely on a small simple engine like this.
None the less, it's worth trying another plug in case the OP got a bad one. And a bad sidestand switch ain't gonna 'weaken' the spark either; it'll simply cut it altogether.

Hmmm, how did we conclude the OP is using a Denso? Last post I read, it was an NGK? Did I miss something?

 

[stopie20]

WTF??? 36$?
I run NGK iridium in everything I own (except the lawnmower) and I have never paid over 7$ per plug!
5 cylinder blast???

 

[go cytocis]

WTF??? 36$?

It's expensive to produce all that fancy marketing to convince folks they'll get a 10% horsepower increase just by using iridium plugs in their street vehicles!

There's a misconception (encouraged by manufacturers of expensive plugs) that 'racing iridium plugs' will produce more power than OEM plugs. The main performance benefit of iridium as used in street vehicles, is extended service life.

In modified race engines, optimized for performance, and running very high revs & compressions, race plugs offer a more precisely placed spark, and cooler heat range. A race engine can take advantage of these characteristics, but they will not be of any benefit to a stock engine not designed for such a plug.

Indeed, as the OP discovered, race plugs may actually be detrimental to a stock motor.

 

[wolfo68]

if they're the NGK's my blast ran better with them it never died like he is saying. Sounds like it's something with the plug to me.

And anyone that pays 35 for one of those plugs (if it is an NGK) should probably pay someone else to install them, they obviously are clueless about what they've done.

 

[StarWolve]

I tried the Iridiums in my Bolt (Not at $36, either!) and it ran like crap. I think it may have been because I was still rebuilding it, and the plugs may have fouled from frequent short runs. I put the old plugs back in, and they worked great. They're still in there

You might not understand who YOU'RE talking to here. I know Blasts better than you know the back of your hand.

A bad sidestand switch would kill spark entirely when the clutch is let out while in gear.

If he paid $35, it's a Denso. NGK Iridium is a $7 plug.

The OP is saying NGK Iridium Race...the suggest Iridium Race plug is a Denso. Both the Denso Iridium Racing plug and the NGK Iridium have been used on stock engines without detrimental effects. There have also been known-bad plugs in each brand. Since the OP is using confusing terminology, it's difficult to tell which plug he is actually using.


go_cytosis ... just don't comment if you don't know the engine, or you're going to be made to look really stupid really fast.

 

[jetlee]

If the OP is indeed using an NGK Iridium Racing plug, please provide the model number so we can figure out if you're even using the correct heat range. The only recommended Iridium Racing plug to use is the Denso IXU01-27 and you can feel a difference when going from an OEM plug to the Denso; they're also almost impossible to foul.


Again, a spark is not a spark. You can have a weak spark or a strong spark. A weak spark may idle, but when load is applied it may not be strong enough to ignite the larger charge. If you knew anything about real engine tuning and diagnostics, that would be it. The fact you're saying "A spark is also a spark, at idle or at WOT." shows just how ignorant you really are.

go_cytosis, you're out of your element here.

 

[jetlee]

The NGK plug to use in a Blast is a DCPR9EIX. Every manufacturer has faults and all plugs have been known to have a bad one every now and then.

However, the OP clearly describes a faulty kickstand switch:
-Put kickstand down
-Put in new plug
-Put kickstand up
-Bike doesn't run right
-Put kickstand down
-Put in old plug
-Put kickstand up
-Bike runs right

You have two options, a bad plug or a faulty kickstand switch. Since you spent $35 on a new plug, do the FREE diagnostic test and eliminate the kickstand safety switch from the equation.

THIS ISN'T FUCKING ROCKET SCIENCE GUYS!!

Jet, I probably am the most stupid & ignorant guy who's ever walked the face of the earth, but it appears I still know something about motorcycle mechanics that you don't. Getting yourself all worked up into a hysterical rage has never, ever, fixed a bike.
