I have been told there are a few providers of non-OEM products. For example, instead of buying a starter, coil, cdi box, etc from the manufacturer, you can get it "aftermarket". Are you aware of any such providers. I am specifically looking for a cdi box that sells for $300 OEM but much less from aftermarket providers. However, I don't know who might sell such items.

 

See if you can locate a copy of Dirt Wheels magazine. Any issue will include numerous ads from both OEM and after-market dealers.
