oil block off

the advantage is reliability, its a good insurance plan for the motor, and also you can experiment with different ratios and find a sweet spot mix for your motor
 
is there any advantage or blocking of the oil injection or do you only have to do it with other mods like raceing air boxs

My 2000 quad ran cleaner after I disabled the oiling system and switched to 32:1 premixing. I've read that the stock system mixes at 20:1 and if this is true then it would explain why my engine ran crisper after the switch.
