What else do I need?

You will need an exhaust system, air cleaner, EFI tuner, and clutch spring and/or lockup to support the appropriate power level of this kit. Milwaukee-8 engines also require larger fuel injectors. Fuel Moto engine kits require installation by a qualified mechanic with experience in engine building and the appropriate tools to check all clearances & tolerances during engine assembly following the OEM service manual procedures and any additional instructions provided. You will need a OEM service manual and some specialty tools such as a inner cam bearing removal/install tool. These engine kits also require comprehensive tuning, we will supply the appropriate FM base tune. Check our FM University site for helpful tips and info.
