• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

F3S O2 sensor

I was trying to familiarize myself with how everything looked under
my F3S scoot and lo and behold there stuck an O2 sensor on the header
pipe. I was surprised as I have not seen or read anything about these
scoots having them and that cats were not a legal requirement. Does
this mean that I have a scoot meant for California? What effect will this
have if any on changing to a different exhaust? My pea brain is curious!!

F3S O2 Sensors

Yep, I understand that. Generally speaking the richer the fuel the
hotter the Cat runs to do the Job. A lot of the current systems
will use two sensors. One to tell how much more fuel is needed and
one after the cat to say when is enough. At least the corvettes I've
owned were set up that way. I guess my question is, is the cat on my
scoot an actual cat or just a dummy? Referring to the manual, there
is a statement that says it is illegal to mess with the catalytic exhaust
system. As far as I can determine, Texas does not require cats on motorcycles.
There were resistors used to fool the computer into thinking that cat
temps were correct and this allowed you set up your street cars fuel systems
like you needed them (you could get some nice increases in mpg). Anyway,
thanks for your reply.
I just be curious.
