The part # might not be the same, but the starters might be. I would be interested in this as well, since my 2 pole starter is coming due soon for replacement.
When I replaced my R/R I was able to cross reference a R1 regulator with a Rhino ATC. Same part , different #. Comes in handy since Royal Distributing doesn't sell much bike stuff, but have a huge ATV section.
Farm bikes are the biggest selling sector in New Zealand. Some
One told me a yamaha quad has the same four pole starter.
Was wondering if any one had tried it.
Otherwise I've seen some on eBay , ricks , they want about 300 shipped.
