2017-2018 KTM/Husqvarna 300cc top end kit. This kit includes a S3 aftermarket cylinder head with two interchangeable domes and a programmable GET ecu with two maps.  I bought this to put on my TC250 but just don’t have the time. I’ve not ridden in almost two years.  This is a factory upgraded kit with all of the power valves installed and ready to go. It comes with two base gaskets.  The piston and cylinder are used but it absolutely perfect condition.  It comes with a unused stock cylinder head as well as the aftermarket S3 cylinder head with two interchangeable domes. For higher compression ratios.  The GET ecu/cdi unit is programmed for the current insert in the S3 head and has a high octane program and a race fuel setting.  It also includes a stock 300 ecu/cdi box that come with the kit from Ktm.  The kit stock is $899. The head is another $249 and the get ecu starts at $600 without the custom programming.  I’m asking $850 for the entire kit. This kit is marketed for the 2017-2018 Ktm/husky 250’s. I don’t know the differences in the 2019-up but it may work, you’ll be the one to find out though before hand.  Thanks!  It’s located in Lineville Alabama zip code 36266. Free shipping inside the US.
