Pretty cool use of surplus parts. Grom fork legs are a substantial upgrade over CT70, especially the K0 pogo sticks...and light-years beyond the cheap Chinese inverted fork legs that are becoming a defacto standard among customizers. There are some really good upgrades for the Grom fork...valving kits as well as high-end (high-dollar) "plug & play" aftermarket fork legs.
That sounds like a lot of painstaking work to the triple tree assembly. I can't help but wonder if it wouldn't make more sense to go with different trees, eventually. Fork trees are a lot more complicated than seems possible, at first blush, aren't they?
You've again piqued my curiosity about full wave stator configuration. Intuitively, an even number of coils, wound CW-CCW, in-series, is logical; the bridge diode rectifier taking half of the stator output on each side, then phasing the two opposite waves into DC. But, this is where there's still a gap in my electrical knowledge...one which, so far, allows a basic question to remain an enigma. Think about the results; we've seen virtually full alternator AC output delivered as DC, meaning a minuscule loss due to rectifier inefficiency. If a fullwave rectifier was turning half the AC waveform into waste heat, then combining what's left into DC, wouldn't there be a huge (~50%) power loss? To me, it indicates that, in laymen's terms what the full wave rectifier does is "bounce" half the waveform to the opposite input pole...and then combine the two inputs phasing...voila!... DC output with virtually no loss. If this is correct, then it doesn't matter if there is an even number of coils, or not. So, here's a true $64(K?) question. If the only requirements are properly phased winding + series wiring and a floating ground, this could be a very easy conversion. OTOH, if an even number of coils is needed, then a 5-pole stator would have to "lose" a single coil...more work but, at 11W per pole, the power reduction would be small enough to not be a problem.
