New XR650R SUPERMOTO PICTURES!!

Post  SMXR on Tue Sep 06, 2016 6:47 am

Hi guys and maybe a ladies my name is Julien i'm new to the site I have two xr650r's one in dirt clothes and one supermoto. My Xr that has dirt tires is a beast has WAY more power than my supermoto and i cannot figure out why. When i bought the SM i knew it didn't feel right the power would surge on acceleration I figured it to be jetting problem. Jetting from previous owner was main 160 pilot 72 (My altitude is mostly ridden around 6,000 to 8,000). I bought it from dealership so I have no background info on work done. Based on a uncorked stock bike and my altitude my jetting should be 160/65. On my dirt Xr uncorked with full fmf exhaust, air box restrictors removed, no holes drilled in air box, my jetting is 165/65 3rd clip and hauls scary ass. I tried this same jetting on my XR SM and its a slow dog feels like my 1986 xt600 (maybe not quite) bogged under half to full throttle would not power wheelie first gear. Since then i have changed jetting one by one with lots of testing. I am now running 170/68s needle 3rd clip and it is running much better but no where close to my other XR.

Considering the jetting I use for my dirt XR didnt work I am thinking maybe the XRSM has engine work explaing why its running better with larger jetting or it could just be the K&N air intake.

I really want to get my SM running right and i know there is plenty of knowledge on here so thank you. If i need to re-post this under different section please let me know.
