All you will need is a perch and lever and a few of your stock parts (we did not include a perch/ lever due to the wide variety of styles out there - However, we do have a nice set listed in this section if needed). Additionally, if you don't have a clutch nut socket, you will need one of those - do not tighten the nut with a hammer and screw driver - it must be torqued on! - Very nice option to use with the 88cc - 108cc bore kits for even more fun and performance! - With the 108cc stroker engines, we do not recommend the use of an inner rotor kit with this clutch as it can cause damage to the clutch housing. However, we offer an upgrade which allows use of inner rotor kits and larger displacement engines with this clutch kit - Please see the Billet Housing upgrade available in this section for more details **Application**: - Z50 - All years - XR50 - All years - CRF50 - All years - XR70 - All years - CRF70 - All years **Includes:** - TBW0249 - TBW0232 **Rebuild support parts** - TBW0302 - MANUAL CLUTCH KIT REPLACEMENT DISKS - TBW0287 - Gasket ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
