i have a 2005 blaster with stock motor and exhaust with the oil injector instald. it runs fine on a full tank of gas but like 20min before i run out it runs amazing and and is more snappy. what should i do is it just need a little tune or what thanks for the help.
runs best on low tank of gas

are you running it on reserve or ON? you might be sucking a little air which is leaning the mixture out which will make it more "snappy" but it isn't a good thing to run it lean. it will run too hot and start melting your piston eventually
Like i said i would assume you are sucking some air in through the gas tank when the fuel sloshes around.
no just stop running it low on fuel. or switch it to reserve when it starts running like that. the reserve nipple is set lower in the tank
you could have the air screw a little to rich as well. turn it out a half a turn and see if it the revs hang or if it just runs better overall. have you adjusted your air screw at all?
If you run low on fuel the fuel may not enter the petcock due to the gas sloshing around and interupting the supply, you must turn to resevere as soon as this happens.
Is the cap breather unrestricted, if it is crimped or blocked it can slow the delivery of the fuel to the carby.
Both the above creates a dangerously lean mixture, even though it flys you could be doing damage.
