i have an 03 trailblazer 400 and have converted it to premix but have heard i need to change the crankcase oil?,can anyone help me on this ?, i already eliminated the injection pump and cleaned the gas tank, but i have not ran it yet till i'm sure i have done what i need to. thanks.

 

Premix 40:1 and you dont have to worry about the crankcase it just has a small amount of oil residue.Now the COUNTER BALANCE is another story.It needs check often and changed any time you get into deep water or at least twice a yr.

 

was going to say there is no crank case oil in a 2 stroke except from the oil in the injection or this case from the premix.

 

cool, thanks guys,thats kinda what i suspected i'm still not sure about the counter balance but i'm going to look it up on polaris micro fiche,but any info will still help,i take it it's a fluid? thanks again. p.s. no water over 6-8'' for me and thats rare.
