I recently purchased a "Triton" chip for my 916 cost circa 20 Euro's
was not expecting anything special,
How wrong was I !!!
starts better,
runs smoother at low revs,
more midrange, (lifts the front off the throttle in second)
lacks a bit at top end of rev range, but hey, who cares!!
here is the link.
took about two mins to fit.
http://www.powup.tk its an Italian site, they do chips for all sorts,
well worth the money.
