Clutch replacement / upgrade

What can people reccommend as a good replacement for a 6 volt semi auto clutch........seen a Kitaco ??? any good ? and what life expectancy would one usually have with an original normal set up gentle/normal riding ,nothing wrong with mine at moment but ive got all the engine apart and just thought i would maybe upgrade to modern stuff so to speak ???? thoughts please .

The most sensible option would be to keep the OEM clutch in perfect condition.
It should last you a couple of tenthousands kilometers.
Check and replace all parts and you'll be good to go!

That will do for me . Thanks Waynus
