How many volts cranking with a permanant magnant stator?

[bassgoat1979]

I did the VF500 stator and votage regulator swap.

Just wondering how many volts the regulator should be just cranking the engine with the starter. i'm getting only about 4 volts. Is that normal? When i hook use the points, condeser and a coil the spark seems weak. It's not a very good battery, do you think when I get the motor installed and kick it good it will be enough to start it?

- i dont run either a battery or e-start but get a nice fat spark from a kick

A bad battery will always make for a bad electrical system, no matter what you've got charging it! So a good start is a good battery, then work from there!

Theres a VF500 conversion too ?
Any pics/info?

- banshee-rd-rz rotor
- adaptor plate
- 3 phase permag stator 103-42-20...VF500 is just one within these specs, many others
- rec reg

- that stator doesnt look properly centered...hope its just a perspective thing

What ignition are you running?

It's centered fine. just looks like that in the picture. I'm running points and condenser no CDI. The bike is going to have no battery and I have the accel cap hooked up. I just been cranking it with a old battery to test it out. Maybe it's because it's turning too slow. I basicly just want it like a old briggs. Kick it to life with old simple points and condenser.

How do dirt bikes, quads, lawn mowers, chain saws, ect. start with no battery? I though is was from perm magnetos. That is why I went with the perm mag setup, no battery needed I thought. I just wanted to make sure it is normal for this setup to have low volts when cranking med. speed. I'm sure it will be fine when I actualy go to kick when the bike is done. i did eveything right and go a brand new condenser and ACCEL capacitor kit ( just to keep the lights from flickering). I am one the right track right?

Good thing about the Shee bracket is the three ears fit exactly to the original XS atlernator mounting alighnment ears so it's centered easy.

Yeah perm mag is great, I run no battery, easy starts no problem, but if you have a crap battery, it will suck the juice away! 4 volts says a problem, a bad battery is a problem, maybe the 2 are related????? cheers

I'll have to get it to turn faster for sure. i was wondering if anybody knew how much voltage they nomaly produce when they are just cranking.

When you say just cranking, are you using a e start or kick?

- yours

When you say just cranking, are you using a e start or kick?

- i assumed e-start

...I found a complete VF500 system here...
Flywheel the same taper/fit as the Yam one?

'61, there's a huge thread on this on the garage. I think you still need a Banshee flywheel, maybe also a RD, not sure.

Once before I posted that a Banshee is a LC motor. That is not correct, I've had a good look at one since & a Banshee motor is almost identical to a RZ engine YPVS, except it doesn't have the power valves. Aparantly the rotors are also different, not sure how though!

Ive been searching 6 months for another YPVS setup (sold my last one as I was desperate for cash!) but good ones are as rare as hens teeth here...
Maybe just the VF500 stators the same then?
I might try and sneak back unoticed into the Garage again..

No the flywheel fits loose!

Just turning it on the bench with the old starter. It seems a little slow though.

I'm running the exact same setup in all my xs"s and it starts no problem w/electric start,probably your battery is shot.To do this mod u just need a banshee flywheel, a new woodruff key,a stator 3 phase I think I used a interceptor and a reg/rec i used a suzuki gs550. There's a whole section on this at the garage that rigg's started a fews years back. There's about 20 different stators u can use and a boatload of reg/rect that will work.You have to use a banshee or rd flywheel these are the only ones that fit the xs.
