oilpump

Hi Folks, It's been a looonnnggg time since I've been on this forum, or kept up with the moto-world! But I have to say, it feels great to be back! Anyways, I'm considering installing an oil injector block-off kit since my blaster is getting up there in age. I've read some mixed opinions about...

I have a 03 blaster with stock pump and resivor. I have been pulling the spark plug to check if there is oil residue after every ride. Is there any other way to check if oil pump is still working. I don't want to convert to mixing.
