try new jetting could be part of the problem??

 

[01 fmf blaster]

ill give it a try hasnt been jetted scince new exuast

 

[dharbeck]

It needs jetted and for the new exhaust anyway. You definetly have a mixture problem

 

[01 fmf blaster]

no i jetted it when i put the exhaust and im still using oil injector u think its starting to screw up

 

[dharbeck]

Black is too rich I believe so it is possible

 

[01 fmf blaster]

ok well i guess ill buy a block off kit the premix for like a month and if it works then problem solved

 

[01 fmf blaster]

do any of u guys think it might be my carb injecting too much gas

 

[fmxr47]

dont buy a block off kit, its a waste of money, just remove the gear inside the pump and put it back on the case, and close the line going to your carb so it doesn't suck air, and remove all the hoses and the bottle

 

[Darrell]

do any of u guys think it might be my carb injecting too much gas

well your carb basically runs with your comperssion to draw in what it needs, so I'd rule that out unless you have bad compression! But maybe pull you carb and clean it real good! I'd just try to unhook the oil pump and premix to see what that does!

ok i just finished cleaning carb and i think it was the problem i should have taken a picture and posted it

 

[just lost]

get rid of the oil injection at the block and pre mix..

 

[wrench man]

There are TWO flavors of "black" spark plug fouling, "SHINY" black is oil fouling, "SOOTY" black is fuel fouling.
Is it shiny or sooty?

 

[brapbrap03]

Are you using injector oil or pre mix oil?

My buddy got oil for me one time and he got the pre mix oil and I put that in my oil tank. Foul a plug every time i rode. (I have the oil injection system on and i love not having to mix the gas)

 

[blasterman312]

pre-mixing definitely makes your plug last longer and it runs alot better
