use a Trx90 Gearbox mounted semi automatic assembly :slomo:
it is similar to a takegawa superclutch basket / cd90
bar it uses semi auto, instead of hand operation ,has 4 plates instead of 5
IMO is one of the Strongest semi auto clutch setup around,
the main issue is having custom parts made,,,, crank adapter/drive gear ,,,oil way etc.
A trx90 uses 2 clutch's the same as a klx110
Regular secondary and a Primary crank mounted centifugal (Very heavy!!)
i had locally re-engineered a takegawa superclutch crank drive gear (18t) with the amount of teeth of the regular honda 50 ,trx90 ,nice110 (17t)
to match the trx90 basket gear (69t)
then used tak's crank nut with seal,
and had a cylindrical steel piece (oil way) made which fits tight in the clutch cover with an o-ring and meets the crank seal
this eliminated the crank mounted clutch and left just the secondary,
the method of pulling off is to slip the clutch using the gearpeg
as most know the trx90 is pull start, though the clutch casing has provision to be drilled out and a regular kick start seal put in place
this method is both time consuming and expensive but the end result is well worth it
