spark plugs

right now i run 8s on my shee and was wondering if i went to 7 if i could exspect a power result. On my dirt bike i had a 9 in there orignaly but when it fouled i put the shee plug in there and BAM it was a whole differnt bike. So i was lik ill try 7s and that thing was a rocket i mean youd wheelie on that thing without even trying.

ive read on here that if you go with to low(as in numbers) that it could burn a whole through your piston i would like some info so i dont burn a whole through the piston on the bike or the shee

 

to recap SIZE 7 FOR THE SHEE,OR LEAVE IT THE SAME

AND IF I SHOULD PUT A SIZE 8 OR 9 BIKE ON THE BIKE(the bikes an rm 80 bored over to a 90 or close if not a 100 cc)

thanks :biggrin:

 

the main reason im wondering for the shee is because i just cant wheelie (lack of skill ,possible)

Run an 8, and fix your jetting.

Then learn how to ride.

8's with gas and 9's with alky.

There shouldn't be any reason to need to change to a hotter plug unless you have jetting issues if you are running pump gas.

Here is a quick primer from NGK:

Moral of the story...run the coldest plug you can that is hot enough to burn clean.
