The yamaha banshee uses the same engine as the RZ350, with some minor extras. I think there are a few differences with the ignition and valving, but the cranks are the same. With this being said, I think a swap to the banshee rotor and stator would work just fine on the XS650. Th banshee seems to be much more available and the parts are newer than the RZ, too. (At least they are more available here in the US). I am currently looking for some parts to do the swap - and I don't anticipate any troubles with the rotor/stator fitting. What I do have questions about is the regulator/rectifier setup. I want to keep the battery in my system. I want to run a large headlight and an LED taillight...no turn signals. But I don't want to cook the battery either. Take a look at this link ( www.dfn.com/benkaren/elecfaq.html) for a wiring diagram for the Banshee, and some cool pictures and info on this charging system. Anyone have any input? What I don't want is to generator too much current and cook the battery, reg, and/or rec. There are three coils on the banshee stator - one for lights, one for ignition, and one of the CDI pickup. Since I'm running stock points, I guess I could use all three pickups for 12V power. I might have to put a reg/rec on each one... or find some heavy duty unit that could take it. I appreciate any ideas.. Thanks, Adam |

Thats interesting.
You could probably use the entire system, it has dual output lead coil.
You can probably only use the yellow output for lights, the charging and trigger coils for ign will have different voltages and are probably useless wired into charging circuit . Don't know the output, 2x 35watt headlight bulbs? and 5 watt tail is going to be marginal to run lights and coils ( less than 7 amps total output) If the lights use 25watt bulbs its only around 4.5 amps, enough to run either ign or lights, but not both at the same time ;D

Well when you put it that way... I understand why it wouldn't work so well.  I do know that there are some people that sell highoutput stator (200W - $185 new), but then you're getting into a good $315 or so with the new rotor. I might just go with that company overseas that's selling those magneto setups. They are just at about $350 for the whole system - and I'm getting kind of tired of messing with this whole idea. I would just buy a rotor, but my stator is ohm'ing out at about 1.2ohms per leg (white to white) - and I wonder if that part is on it's way out, too. I don't need the electric start - I plan on pulling it. I would like to battery because I want to run a good sized headlight. Guess we'll see.. Thanks for your response.. Adam |

I had a thought.    The Banshee is self generating for ignition so you dont need any extra for ignition coils (duh  ) all the output can go to battery charging or direct lighting would be fine as long as your not going far enough for battery to go flat (even then it would still run though) PJ But the Banshee ignition is CDI with an advance curve that is tailored to a two-stroke twin. It may not work well with a four stroke. I'm not sure that the crank end tapers are the same either and if not you would have to get the rotor machined to fit the XS. |

HHmmm... That looks like it might be a good swap for my RD350. Anyone know if that will or will not work. (it is a 2-stroke, twin)

I wonder if this is anything like the SR500 system? It has the same triple-winding kind of design with a CDI winding. (Consider the XT500 alternator too, it wouldn't have the CDI winding since it has points.)

I don't know about US model XT's, but the European ones were 6 volt and not particularly powerful at that.

I had the idea that we were looking for something easily available and more reliable than the stock generator?
There are thousands of RD350 and Banshee generators out here (so I'm told, haven't checked) Need to make a back plate to hold it but the 'magneto conversions look a lot like an RD generator to me. You could set timing for correct full advance and worry about he low speed later? I don't think the advance curve will be too far out, the XS is pretty tolerant in any case. Only real problem I see is it wont be usable on a re-phase.

From my understanding from Dave Raynor and the talk of the RZ350 conversion, the taper on the RZ350 is the same as that on the XS650. I know that the banshee runs the same engine, minus some valving changes, so I would think that the taper would be the same. The key size/shape is different, but the purpose of the key is to index the rotor for the CDI system. As I understand it, the key plays no part in holding the rotor on the crank.

I like the possibilities here for a rugged, simple setup. Two stroke advance curves retard at high speed so you wouldn't want to use the Banshee CDI, that would just add to the cost anyway. Instead, you could run the magneto output to a lawnmower CDI module and trigger it with a Toyota pickup in place of the points (like the $19 junkyard ignition). Or, if you're really cheap, you could trigger it with the points. Either way you could used the stock mechanical advance.
As I understand it the stock Banshee lighting output is 85 watts, this is enough to run a head light, tail light and LED turn signals. You would only need a battery if you wanted the lights to be on when the motor is not running. When the motor is running the battery does nothing but add a load to the alternator.
I checked my Yamaha cross reference and it shows the crank is the same for all years and models of RZ350s and YFZ350s. So it stands to reason that if the RZ350 rotor has the same taper as the XS650 crank then the Banshee rotor is the same also. The only way to know for sure is to try it. I found a Banshee rotor on ebay for $5. If it fits then I'll scare up a stator and figure out how to make it all work. The charging system on my bobber project is toast, this could be the perfect low buck replacement for a minimalist ride.

Found a perfect CDI box for this swap. It was originally used on smaller Honda bikes but now is used on most of the Chinese Honda-clone bikes. The China made units can be bought new for less than $20 and tha Honda ones are all over ebay. It has the advance built in so you can trigger it with the trigger coil on the Banshee stator.
I sure hope the crank taper is the same because I'm really looking forward to putting this all together.

The left side crank half used on the RZ-350 and the Banshee do use the same part number. which is 29L-11412-00-00. The wood-drift key is also the same -90280-05033-00.
However, the RZ-350 used 4 part numbers on the rotor, starting with
51L-85510-50-00
29L-81410-50-00
51L-85550-50-00
29L-81450-50-00
The Banshee rotors are part #
3GG-85550-00-00
2GU-85550-50-00
I'm not sure if this casts any light [no pun intended] on the subject, but this thread is interesting.
Regards
John

There are high-output banshee stator/rotor combos (200W) out there - but they aren't cheap. I would imagine that there's a significant output difference from those supplied from Yahama. The banshee wouldn't have the power requirements that the RZ did.
I ended up buying a rewind from Custom Rewinds - maybe I'll get into the swap another time.
