starter brushes

[thumper2146]

has anyone found a non honda set of brushes that will fit cb72/cb77 starters? i found some on ebay but at 24.00 each seams kinda steep to me

Have you stripped yours out and inspected? You'll more than likely not need to replace them unless their free length is less than 8-10mm. Or unless the power wires have broken.

yes had them out but there just a tad short while i had it apart i also chucked it up in my mini lathe and cleaned trued up the communtator and undercut the mica starter has much more power than before

Good call; undercutting is an important aspect that often gets overlooked, thus causing unnecessary arcing and commutator / brush 'burning'. These brushes actually rarely need replacement, but $25/pair is about the going rate for our relatively rare copper-graphite items.

Forum member FAST FRED KOREN advised me, a while back, that Ohio Cycle stocks both Kokusan and Denso brushes at that price. There's usually a brass manufacturer's plate on the motor body.

G'luck!
