If you haven't already, get an oil block off kit and premix your gas. This will not only increase your performance but also prevent engine damage. You'll know when your oil injector stops worrking when our engine seizes.

 

How do you gain extra peformance from switching to premix? Either way your still getting the oil to the cylinder. Maybe if you switch brands and lean on the oil mix a bit by running 40 or 50:1

 

You get extra performance because you are getting an accurate mix with premix gas/oil. With the blaster's injection system you invariably get too much oil into the mix.

 

And how do you purpose that happens? The pump is built to increase the output of oil as the RPMs require. No performance, just peace of mind.

 

Like anything else mechanical, it requires periodic maintenance and adjustments. It also requires to stay clean in order to work right.
Oil injection is not new, my 1974 Kawasaki H1 500 had it and it worked fine. Occasionally it oiled my boot, and I changed-out the crush washer, that's all.
