I just bought a 07 xc-f 250 with a 300 bolt on kit. I took the bike to a local shop that I trust, and the mechanic told me he was checking the valves and he noticed that the tps was disconnected. The previous owner seems to have upgraded the bike cpu? Does anyone know if an aftermarket cpu require the tps to be disconnected? Also we nkticed the hot start port on the carb is sealed with a bolt? Any belp or opinions will be appreciated. As a new owner of my first four stroke I can use the help. Thanks eric.
