BGM stator problems

[10 inch Terror]

A real simple way to check if the BGM stator is producing a spark would be to fit it and simply hold the green to your engine casing and kick your engine over. If it produces a good strong spark off the casing then you know the fault it elsewhere. My old uncle once told me ALWAYS check the simple things 1st as 90% of the time it's something simple at fault.

Multimeters should not be hard to find. Lidl here have them for about £8 this week. Maplins always have them from about £5 to ££££. Did I read you are located elsewhere? So that info may not be too helpful other than showing they are not very expensive and are widely available. There's always places like amazon.
They are well worth the cost, you can actually verify all sorts of electrical problems, not just on the bike or car, but at home too. There's bound to be utube/ehow on the www.
They can be a bit fragile, so don't just toss them in your kit box.
Remember to turn it off. Resistance is measured by sending a small current from an internal battery and it will be flat next time if you don't.
Sometimes the flyleads are crap like on mine, giving inconsistent readings but a bit of a rub works wonders.
Thanks for reading.

Looking at a few of your other pictures online the connections on the BGM are not standard spade connections. You are then plugged into another loom that goes where? Extra connections should always be avoided as each one is a potential breakdown. Your BGM stator should go direct to your CDI with insulated spades, soldered to be sure. The round plug and bullit ones you show look uninsulated and all touching. it will never run like that.

Dont hack your stator around and play with the pick up..............this is 99.9% unlikely to be your problem if you are using an Indian flywheel.
To me it sounds like you have had an intermittent problem with your original system and changed the stator out of the chance of being that without properly diagnosing the initial issue.
Put your old stator back in and if it is now completely dead the issue is somewhere else in the system. Indian ignition switches regularly fail in this way and so do CDI's (indian or italian) or it could simply be a loose connection (forget the regulator as thats for the lighting system). Get a multimeter and stickys book and follow the test procedure and learn how to test your ignition switch and continuity on wires or take it to a reputable scooter dealer otherwise you're gonna mess up a brand new stator and chase your tail on diagnosis.
Hope you get it sorted.

I think that you're reconnecting like for like wires based on the colour. Looking at your pictures your Indian stator is a SIL one with Yellow wire coming from the pickup whereas the BGM has Red wire coming from the pickup.
I've made that mistake previously.
BGM pickup to CDI is Red
SIL pickup to CDI is Yellow.
BGM stator to Regulator is Yellow
SIL stator to Regulator is Brown
Other 2 wires remain the same.

Arrgghhhhhh!!!! Why didn't you tell me before!!! I just came from the garage where i spent 4 hours until i figured that out myself!! I was close to dismantling the whole electronic sistem!! I even went to buy the multimeter!! (19€). Now it sparks big time!!
However... just to complete the post in case someone else will bump into the same problem: the Sil sitem works this way: the main loom that come from the frame splits into 4: 1) goes to the rear light, 2) goes to the stator (white green brown yellow) 3) goes to the regulator 4) goes to the CDI (white, yellow and green) .That's why you have to connect the stator to the loom and not straight to CDI...

Thanks everybody for the tips .. @terror: i tried your uncle method in the first place and it works! @corrado: ma sei italiano??

You should try READING other replies to your problems then you wouldn't have wasted your time

.........because it is also possible that the colours used on your old stator don't correspond with those on the BGM, the Indians were notorious for using none standard wiring

i tryed all the options suggested here in the forum (including changing the indians connectors with the bgm spade ones... twice!) and yours was one of them... Corrado's advice was a little different since he had EXACTLY the same problem i had which would have automatically excluded all the other options. I wouldn't call it waste of time anyway since now i know lots more about the electronic igniton of my GP Tomorrow or sunday i'll take a little road test... still have some doubts about the rear light thou, if i remember correctly only the rear brake light works... and why the "earth" wire is not in its place in the regulator ... http://imageshack.us/f/833/d7gf.jpg/

Hello can anybody tell me the correct ignition timing of a Mugello 225? Some say 15degrees btdc , others 17, 19..... Any info appreciated. thanks.

It depends on the quality of fuel that you will be using and the amount of Ethanol in it. The safe setting for 5% is generally considered to be 16 or maybe even 15 in a highly tuned motor. 17 would be the limit, I wouldn't personally run with anything more advanced unless an retard unit like an Augusto was fitted.
