well today I decides to put some of that 44K engine,fuel injector cleaner, into my 929 and now when I rev it a lil I get some pilows of black smole, and if I crank on it it will spit out fire.

is this normal?

I also put some in my yzf600r and it smokes also when I rev it but no flames

the only motor mods aside from the 44K was a BMC filter and velocity stacks, and no flapper.

so I'm guessing I'm not running lean. lol......

 

well the stuff is concentrated to treat about 12-25 gallons so it might have effected the bikes 3 gallons more than it should, just run out that tank, hopefully it make it too lean

 

I didn't poor the whole can in my bike!

I put some in the 9
some in the yzf600r
and some in my 12 gallon cars tank!

 

i put it into my 2001 also got the same results. i have used it for years in my cars as i am a dealer for bg. it should go away after you run out the tank. it is just working cleaning out the junk on the valves and throttle boddies. mine did it only when i rev it, but no flames. it has already stopped . using bp raceing fuel now so it should be completely cleaned out.
