have a stock 04 blaster, it has that oil injection and we are going to go to the oregon dunes (sea level). Do I need to do any jetting adjusting to potentially save my top end or what, normally I would just run more oil in the mixture but you cant do this with the blaster (unless you plug up the oil injection and then mix), Any suggestions would be great, thanks!!

 

I say, get rid of your oil injection all together and just plug it. Premixing isn't hard and you KNOW that the oil is getting in the engine. My experience with a previous blaster with oil injection was not good. We THOUGHT the oil injection was working, but it took a blown engine for us to see it was not. 300 dollars and a new rebuilt engine later, it now has no oil injection and will never have it again.

 

so if I plugged it up I would no longer have to mess with the jetting, just add richer mix..? What mix is safest when at the dunes and what do you recommend for trail riding, thanks again!
