Now i know i have to lower the Main jet, but my problem is the next jet i have down from the 170DJ is a 160DJ.. i'm missing the 165DJ

If i put the 160DJ in to do a plug test is there anyway i can hurt my engine if its too lean?

does anyone in NJ have the same bike stock bore than can guide me in the right direction here

any imput it appreciated, thank you

nope, you won't be too lean. i actually hear guys running the 148 DJ with a piped and filtered bike. i would say a 160 is going to be too big but that is my opinion.

yeah, i hear people running a 148 DJ with a modded lid. if you want you can always start with a 155 or 160 and work your way down to where you want to be.

Yep, the 155 was too rich for me.

I'm pretty sure I'm running a 148mj with vented airbox.
