Recommended main jet size

[mikeski]

What would be the recommended main jet size for a Blaster with the following mods running at 1000ft above sea level?
Air box removed
K&N filter
Vforce reeds
FMF Fatty gold pipe
FMF power core 2 silencer

I purchased the vito’s jet kit but I would like to know where to start so I don’t have to remove the carb and boot multiple times. Any help is greatly appreciated.

Thanks

I'd start @ 260 then a plug chop

I'd start at a 290 jet and go from there.

290 is to big...maybe a 250 or 260

Well if the air box is removed and your using a clamp on filter your gonna need at least a 290. maybe as high as a 320.

I agree with the last 2. I am stock with a "swissed up" lid and uni and ended up with a 270. But I also run 25% VP c12 race gas. So I think it would have been around 260 on straight 93 pump (seems to like Mobil best) I was VERY suprised how much you can richen the main jet after just unplugging the intake!! Let us know what you end up with. I:I
