You could be right...... it was old when I bought it and thumped at every lamppost.... I loved that thing, simple, naked, didn't fall apart when I got stuck in the tram lines and fell off, started without fail once I got the technique right. Anyway..... back to the Virago.... I have tried uprating the battery but it still looses charge after a few weeks.. there must be some upgrade I can do to get the charging required. -- Biking for 37 years. GOM

Even many modern ones. There's always *this* alternative: http://xs49.xs.to/pics/05400/400Falt1.jpg http://xs49.xs.to/pics/05400/400Falt2.jpg My dad did that to his 77 Honda 400F. It was all bolt on, no permanent modification to the bike. Charged real nice at idle... That's a 100 AMP GM 1-wire alternator. (That's 1200 WATTS if you're counting, compared to the 140 or so of the stock alternator) -- "Outback" Jon - KC2BNE outback_jon(a)ver.no.sp.am.izon.net AMD Opteron 146 (@2.8) and 6.1 GHz of other AMD power... http://folding.stanford.edu - got folding?

Your right on all that, I have tried them *batteries* at up to 15volts, and that is VRLA called Gel,, but the Battery manual states Wet Storage which is SLA Lead Acid.... The manual cautions on overcharging above 12.8v, but they gotta be kidding ...............then they state in the specs that 12.8v is the minimum open circuit voltage as per all the other normal batteries... |>Magneto provides spark, not charge.

The Charging System on the Majesty yp400t ------------------------------------------- Charging System: System Type A.C. Magneto Model F5RU (MORIC) Nominal Output 14V/27.5 A at 5,000 r/min Stator Coil resistance/color 0.184 ~ 0.276 ohms at 20deg. C (68degF)/ White-White ----------------------------------------- Rectifier / Regulator Regulator Type Semiconductor,Short-Circuit type Model SH678-11 (Shindegen) No-Load regulated Voltage 14.1 ` 14.9V Rectifier Capacity 22A Withstand Voltage 200V ----------------------------------------------------- So the A.C Magneto is another word for Genetator/Alternator/Stator Coil....we always get these terms mixed up because the manufacturer does..
