dr 650 jetting


Recommended Posts

I would like to get more power out of my 97 dr650, but like how quiet the stock exaust is, what are the best jetting/ airbox mods with stock exaust at about 300ft above sea level?

The DJ kit is your best option. Since you don't want excess noise you will ignore the DJ kit instructions to remove the air box cover and just do the air box mod as posted on Jesse's web site. Use the DJ155 main. 👍

Sure you would.... but just like JD and other performance jetting establishments they don't sell components... just the kit. If you want to piece meal something together read this quick a minute. 👍

I'll nutshell it for you. if you want to really improve the DR650's volumetric efficiency you have to do the airbox mod. If you do the airbox mod you have to get the DJ needle to supply enough fuel for most of the throttle range.
