hey i know this isnt going to answer your question, but just from my own expierence, get rid of the oil injection. when i bought my blaster we rode it one time and it blew up. it had oil in the oil injection tank and everything, we thought it was an old bore so we didnt bother to check the oil injection system. we threw on a brand new top end on the bike. not even 2 hours of putting around it blew up again!!!! come to find out the plastic gear on the injection pump got shredded. my whole summer riding season was ruined all because of the stupid injection system. its better to just spend like 30 dollars on an oil injection block off kit and suck it up on pre-mixing your gas it will go a lot longer, and its a good insurance tip if u wanna look at it like that. lol. just a piece of my horrible expierence to help u from having it done to u.
