I haven't had to oil injection system on my blaster since I got it. I had it a week and took it off. I did not remove the oil tank in the rear though. I simply closed off the hole where the line connects to the pump goes and installed a small valve into the bottom of the tank.(similar to the fuel petcock valve on the bottom of your fuel tank). I just keep the tank full of enough oil to mix 4 gallons of gas @ 32:1. This way I'm not stuck somewhere on empty. I simply made marks on the tank for the full mark and the half mark. Let me know what you think.

 

That does sound like a good idea! You always have the oil ready!

 

have to let my brother know about that, great idea.
