    The XR400 powerplant is chillin' and ready to visit secret location. Time to get that tranny fixed and maybe even a little top end freshy-fresh'en'ing.

    Clutch basket looks like it has been used for basket weaving:

    This clutch basket is TOAST! Notice the areas where the clutch plates sit in the basket and how they have worn grooves in the basket. This is what lends to "hard pull" on the clutch lever. I was always so excited to go ride, I never complained about how hard the clutch was to pull. So, now to see if anyone has an aftermarket clutch basket or go with the good'ol factory Honda clutch basket.

    The previous owner/shop/racer team of Rick & Phil Gero of Vance & Hines Motorcycle Center located in Sun Valley, California built this bike for his Phil to race in the desert. That was many years ago! Then the bike was sold. Then loaned to a friend and so on before I secured the bike and brought it back to Rick to service as it sat for 2-years or so before I saddled it up.

    Basically, it's had a HARD LIFE!

    So I guess this is what the HARD LIFE looks like.

    The rockers have been over rocked like G-Pa on the turbo rockin chair!

    This bike has the 440-kit in it, plus the cam, so I bet back in the day it ran strong. I will give WEB CAM a call an see if they do a re-build/grind, or purchase a new WEB or Honda Factory cam. Maybe a WEB CAM with some Cryogenic treatment? Either way, with the engine re-freshed, the DirtDawg is going be AWESOME!!!

    SO, the main reason for tearing the engine down...

    Second gear lost four teeth on one side and one tooth on the other side. This is a CRAZY RARITY for a XR400 motor! This bike has had a hard life before I got my hands on it. But still a rarity! Time to get some parts together to rebuild the DirtDawg!

    The oil pump cogs are scared a bit and will replace these. Replacing these will help keep the oil pressure up to par and oil pressure is the lifeblood of the motor!
