Driving off the crank with the original Kubota pully it is being driven at approx' 1: 0.9. This is not cutting the mustard for me, any other figures ( related to crank rev's ) from other Kubota users.
Thanks

I like the sound of that Norman, What sort of price does that work out to.When you write Kubota do you mean the rather small alternators which were designed just to keep the battery charged on Kubotal powered machinery or the larger alternators, also used on Kubota engined ride on lawn mowers etc. The latter have a diameter of aboiut four inches and can produce 40 amps. They are usually marked ND for Nippon Denso. I now provide those for 'Walkernator' kits and on twins they run at double the engine speed. On Comets, due to restriction on the space in which I can fit the pulley diameters they only run at just over engine speed. Several people have used the small ones but they were never meant to provde light, indicators, heated gloves etc.
Have been advised that the crank speed on mine should be upped and I was thinking of something like ths. I think I can knock one up on the lathe but have you seen the ££ of billet aluminium.My 40A Kubota is belt driven from the crank and runs at nearly twice crank speed. Had no charging problems. Have electric start and battery powered electronic ignition but don't use many other electrical accessories, although I am confident it could handle more.
Ignition warning light goes out above 800rpm.
