Part #09319-14005   BUSHING
#2 in the crankcase fiche.
I like the old style CDI/coils.  The new style isn't any better yet twice as much to buy.
Plastic and such:: All LT80's are the same with the exception of the CDI and chain size.
Yes, I can make you a nice aluminum piece to re-connect the tubes. 20 at your door.
