Looking for opinions (dangerous, I know) on a swap from our existing Parilla Mini Swift 60cc race kart, which is being modified into a fun yard kart (won't be raced.)
My son wants LED headlights and taillights and would like to retain key start. I've seen that the Briggs engines can handle electric start with factory parts and alternator, as well.
We could use more torque for the 13x6.5 tires, up from 10x4.5. Got a taller gear (97t vs old 82t) and that's fine but it still takes a bit for any real grunt.
The chassis and axle can handle 4 stroke mounting...the seat cross brace is not a clearance issue. I'm thinking we could drop back down to a mid 70 tooth sprocket with a 10 or 11 tooth clutch for more clearance and the torque would still be good but maybe I'm wrong. His top speed might be affected... currently it spins 11,000rpm and does over 40mph. We'd be fine with low 30s, I think...again, no racing, just fun. It'd be nice to accelerate more quickly vs top speed.
Another reason for the swap is maintenance, parts availability, smoke (he hates the idea of unnecessary pollution), and noise (these things are really quiet compared to the Parilla) to keep nosy neighbors away.
Electric is outside of the budget. So now, I'm interested in thoughts and considerations to keep in mind with this swap. Thanks!
