I know people have been waiting patiently for this it is under way. Im still waiting on a after market exhaust to get here from barkers and some parts to make some modified ones. From initial testing almost a wash for hp in stock form vs a 14/15. For running lean though its even worse in stock trim unmodified anything its very lean anything below 1/4 throttle adding a little fuel picked up roughly 10% hp or 2-3 hp at wide open throttle.

The fuel addition is responding even better than 14/15 but the airbox is way better in stock trim, my modified lid we tested is marginally better HP wise nothing like it did on 14/15 this stock box just gets more air to it so the gains are not there.

Everyone is going to need a fuel controller though in 100% stock trim.

Im shooting a bunch of videos with my mug in there so you can be part of the process with me 🙂

slight gains taking tip out much better than airbox as well and running it really need extra fuel then so if you have no tip and no fuel controller put the tip back in until you get a tuner. I know it sounds like a scooter but its very lean
