Soldering is the best, but stator is in a pretty dry, hot, unfriendly place. Splashed oil is only cooling provided, & new stator will fry like the last, but heavier winding's on replacement's, soldering wires, is the best I can do. Replaced connector's with HEAVY BRASS ones, new locking plug's, like the original. new plug melted, silicon grease, melted as well. so I solder, heat shrink,& forget about it. Friend of mine uses connectors from radio shack, come in bar's with screw's you can break to size. Leave space between connector's for cooler connection's? Might help keep joint's cooler, so they don't melt, if you don't want to solder, & be able to take apart. Hope this is helpful.
