This product makes the TPI bikes into the way they should have been made. This product is just the block and injector plugs you see in the second pic. It doesn't include the reed block or injectors.
On the 2018-19 bikes, the oil pump will hit the block , by 1mm. So, you'll have to relocate the pump a bit, like in the picture, to clear. Ther e are many ways to do this. Just know before you buy.
You can see the dyno proven top end power increase, and there is an increase everywhere. Also there is a mileage increase of around 5 miles to a tank of gas
By moving the injectors before the reed cage, the fuel can now mix with the oil and air, BEFORE it enters the engine. Just like all carburated bikes before. Now the crank can get lubed, and the top end, before the bike starts. Not only does it keep the cylinder and crank from running without lubrication at every start up, power from idle to wide open goes up as well. Works with stock or aftermarket ( GET ) ecus.
