I strongly urge you to relocate the regulator from inside the fairing to behind the rear wheel (see picture in my above post). I had five regulator failures before solving the heat problem this way. The regulator simply cannot survive the heat from the header pipe plus it's own internally generated heat. Even out in the airstream it gets almost too hot to touch. |
I take your pont, but unfortunately I don't live in a Californian climate!
I can see the advantage of siting the reg/rect more "out in the open", but I'm not sure it'd survive long in the path of the mud and rain it would often be subject to in a typical British "summer"!
However, today I saw an ST2 where the rect had been sited behind the vee-piece, which had a custom "vent" in it I think I'm right in saying that's not standard?).
My understanding is that the three-phase alternator and rectifier set-up, although not perfect, is generally considerably more reliable than the single and dual-phase set-ups on earlier bikes.
As far as locating the rect is concerned, clearly there's a balance to be struck between ventilation/cooling and weather protection. I can remember the old British Triumph twins, where the so-called Zenor diode (regulator) was sited under the headlight, for similar cooling reasons.
