I have a fully stock 2000 Blaster. I am going to add a FMF Fatty and a FMF Power Core II. What kind of regetting do I need to do? How big of a jet should I change to and will I have to change anything else other than the main jet?

Thanks,

2000 Blaster - stock

 

FMF will give you a choice of a 260 of 270 mainjet I believe. I got my Blaster with just the Pipe and the person was running a 270. It was running way fat. So I put in a 200 and it ran great. I run at 200 above sea level.

 

did you ever check your plug? It has to be running lean! The stock blaster comes with a 230, and you went down to a 200 with performace parts! Why? That makes no sense.

 

I agree w/ 2000blasterboy1 that makes no sense at all you should at least be at a 240
