iv gone with a hotter plug because i couldn't source a br9 so just got a 10 instead..will it make much of a difference? i was thinking myself hotter is better
I would get rid of the br9es or br10es and go with a br8eg you can't flood them and they run hotter then the Es do
I have experimented with many different types of spark plugs. I have grown to be verry fond with Desno and NGK's. I have also tried a totally different style spark plug. One that was designed from a much older design. This plugs is called the Torque Master plug. Its a small company based in California. This plug does deliver what it claims as far as torque. But, longevity it does not. Then I came up across these new plugs in which were supposed to be part of the Harley Davision line. These plugs are called the Pulstar spark plugs. Let me say this These plugs are great and performed awsome in my bike. When I tried them. You will notice a performance increase in all power ranges. They were expensive yes. The bad thing is I found out that I could not trust this plug to not cause engine damage. The bike started spitting and sputtering when I was on the track. I was able to get back to the truck. This is what I found when I pulled the plug. The plug is a be1i Pulstar plug.
A br6i is a verry hot plug. The lower the number the hotter the NGK plugs get.
You wasn't running too rich for sure.... That first piston is roached.
A "too rich" condition will make it bog like no other, and put the plug out.
Your chasing a piston/cylinder problem with the spark plug. That cylinder needs replated. A hone will not fix it, not even supposed to hone a nik plated cylinder. Send your new piston and ring with your cylinder, have it replated matching the piston.... When you get it back, install it with stock jetting (clean the carb) and air screw setting, with the stock plug... And tune from there.
If you don't know how to 2 a 2stroke carb, Your going to need a few spark plugs. Save your plugs too. (Once you get it jetted correctly, You won't foul anymore plugs. And it will run tits.If you still need more power, Its time for a big bore or a 250...
have u more info on replating what it promotes etc? and how u know it needs to be replated?? its nearly time for a 250 i just got the 125 to get comfortable ridding as im not ridding bikes long..
