yeah. I run bel ray synthetic injector oil in my blaster, and it's a blue color. well not to long ago oil started to come out of my tranny over flow tube. so i drained some oil out of it, and it ran fine. well then i noticed my oil in my injector tank start to go down faster than normal. i'd run it for 3 hours and be on a half a tank. then oil started coming out of my over flow tube for my tranny again. hmmmm. the injector line running through my transmision must have a leak b/c that could be the only way extra oil keepsgetting in my tranny. how do i know this? because when i drained more oil from the tranny the second time it was the same bright blue color as my injector oil. ! messed up ! I'm blocking off the injector and running premix. just another story about why you should block off the injector.

 

the line doesnt run thru yor tranny does it?
the line goes undernearth the sidecover not thru the trannny.

 

I dont trust the injectors either, I purchased a JR50 and immediately plugged that puppy up and mixed my own.

 

there should be a seal or something between the pump and the case side. This may have gone bad. You could plug up the injector and run premix, or replace that seal. I am not positive about how that all fits together. i doubt you would have to split the cases to change that seal. Get a service manuel and call it good.

 

do you think the 2 stroke oil in my tranny hurt anything?
