spark plugs.......

I've been following similar threads here regarding plugs.....and several of them proclaim that the stock plug included with the kit is a POS......well ...so far I've not had ANY problems.....removed it several times to check condition....it's always the * brown * color that everyone says is what is good....sooooo .....what are the benefits of other plugs ?.....I realize this might be a redundant thread but I still would appreciate a comprehensive response......THANKS !

Laters,

The NGK bp6hs has a deeper protruding electrode that seems to run better in my motor than the stock. My motor seems to have a cleaner two stroke with more power than the stock, not only this but NGK is a good name brand that i have used in dirt bikes for years!!!

Keep a close eye on the outside electrode of the kit plugs. They seem to be very soft and easy to move. As soon as I noticed that I tossed it and went with an NGK B5HS. For a couple bucks it was well worth the peace of mind that the elctrode wasn't going to break off and knock a hole in the top of the piston.

Have to agree with Wes, Soon as I put in a BP6HS, mine ran better even tho the color of the original was fine

Most of the time, the stock plugs work fine... But it's a real crap-shoot.
When ever a bike starts running like $**t, I look at the chinese plug first!

I have had china plugs that shot the porcelain like a bullet, and ones that have run a thousand miles with not a problem.

Sometimes the stock plug is fine. Most times not. My first one fouled almost instantly. Now I never use them, but one did have the floating electrode disease.

i was looking on one of the parts sites that sells different plugs, and some of them have a note in the description saying something like "best used under/over a certain temperature". do they really make that much of a difference when used in conditions that they are specified for?

yup. colder plugs in a colder environment will make your bike sluggish and bog, and hotter plugs in a hotter environment will make your bike run lean and kill it.

by going up or down one heat range won't affect it much, unless you're going for absolute tune-ability.

it comes down to what works for your particular engine, in it's environment.

i'd start with a NGK B6HS and if it works, stick with it. if you want, get a 5 and a 7 too, and play around with them.

and my suggestion to everybody, (which is still just my opinion) is to never even install the stock plug in the first place. like Joe says, some work, some don't. you don't want the one that "don't."

a 4 dollar investment could save your bike.
