Spark arrester question...(jetting)

[Groves187]

Ok so i am thinking about taking out the Spark arrester out of my White Bros E-series Exhaust and am just wondering how many jet sizes i should go with, The air box lid is off, and all other mods are listed in my sig. Would me bumping one jet size up then i run normaly be fine, or do i not even need to rejet for this??..thx Nick

I did that and needed a 165 main. Im at around 1000ft. If you take out the sparky than you can remove the disks for better looks.

Hmmm, Not sure what i am running in it now, Just bought it the other day, Do you think steping up a size will be ok??? or should i go more?

Depends. If its stock i think stock is a 142 but not sure. Just have to keep going up till the plug looks good and power feels good who knows maybe the jetting will be fine.

The lid and filter only afect the needle (mid throttle.)

I think you can just adjust the air/fuel screw but i'm not sure. I have the same exhaust but I never tried that before. If anything go up one size on the main.
