@Dafc - Why would I need a Mico, be it original or fake, when I can source a genuine NGK/BP7HS here

?

But @Dafc, think about what @Dpak says, he should be right on the fake front. AFAIK, no one makes more than 20-25% margin in automobile spares including the 4wheeler segment. So your 50% margin justifies for it.

ty bro!!! moreover it would be very helpful if someone posts how to find a fake plug!!

I had not gone down to comparison between plugs to find out the difference. However, there is one way to ensure that is, buying from authorized dealer. I was able to get the NGK plug from Authorized distributor in Chennai and also, you can get the OE plug from Yamaha showroom where the box has Yamaha print on it. I have bought this sometime back. With regards to price of the plug, I had not paid much attention.

this is the pic of my 5HS plug after a day's ride after cleaning it!!

**dafc** · 02-08-2011, 11:19 AM

Insulator looks good, but to really get doubt out of the water chop her up

**aargee** · 02-08-2011, 11:27 AM

^^^ Is that after cleaning? Man!!! you need to learn to clean better!!! Lol!!! See the carbons surrounding the plug at the bottom? You need to clean those too. Not sure if you've cleaned inside of the plugs too!!!

aargee i dint clean it ...it was done in YSS..and can you tell me where you are mentioning??

@all:guys this is the 5hs plug...i am going to change to stock 7hs...

Oh!!! ok, sry, I got it wrong. From the looks, it seems the mixture is right. But reduce the oil inflow, looks like it has more.

pls no formalities brother!!!

i will change asap !! still i've been using this 5hs plug for a year or more..!!! pheww it dint give any problem, though it is of low heat range...and it gave me 30 km/pl!!

funny isnt it! ??

**aargee** · 02-08-2011, 11:56 AM

Tks DPak

Nothing funny as I don't see a direct relation to consumption & plug. Ofcourse I do believe & see a direct link between the plug & cold start.

i think plug do affect mileage marginally!!!because the spark timing and intensity should be high for a rich mixture isnt it?? and vice versa for other end..and this shall be possible only if you select the correct plug with correct heat range!! (for rx 2-12) so running on a wrong plug means that you are wasting fuel (may be marginally depending on the wrong plug range ) and power...!!! correct me if i am wrong !!

Yea very marginally, quite negligible. However, I would only appreciate some senior's voices here for education

Timing is dependant on CDI & intensity on the capacitor charge/ignition coil. Yes, a little on the intensity could affect, but, I'm unable to relate much, 'cause, I'm thinking that can be overcome by mixing less oil by trial & error so that lubrication is not affected much.

No, I'm not very sure, that's why I like to see some senior's pitching in. Like I said before, on cold starts, I know to relate, but not on warm engine.

sir what you have said is absolutely right!!but when you tune a bike for stock plug including timing and coil , and when you plug a wrong plug > you lose something right??!! that's the simple concept behind this !!

correct me if i am wrong

**dafc** · 02-08-2011, 05:56 PM

if you are using the old design spark plugs instead of halo or quad prong plugs in that case the plug only affects the power. Mileage and power go hand in hand and they are determined by jetting. Rich lean blabla all comes into the scene in jetting. The heat range of the spark plug determines how much heat is transferred/retained when it is firing. You can fire a hot and cold plug at the same voltage and current level. It's all about the design of the insulator. NGK iridium plugs are better though and take a better picture of your plug can't see the if possible point the insulator towards the camera and take it in a well lit room

so you say irrespective of the tuning the bike has been set....a wrong plug goes well/in par with stock plug in terms of timing??
