I bought a Bgm stator from mb last month as I had thought they where going to be up to the job.
Anyway its set up with an af light flywheel (new with the extra washer to space it properly) and was fine up to kelso and back. Also fine up until a week ago !
Now it miss fires and back fires at high revs and is a bitch to start. No rub marks on the flywheel and the black box is not marked or loose on its mounting. (no rubbing against the flywheel)
Anyone lese had any probs like this with one?
Im going to put the indian one back on and ring Mb but could do with some feedback from others as im not sure if im going to keep using the bgm ones if this happens.
Bgm staor probs

have you tried a new HT coil.........?

I would also check the CDI first... As they are usually a reliable stator, and a good setup when used with the AF flywheel (Thats if they dont rub)...
I spoke to Mb today only to find out it is a problem they are having with the Af flywheel and it doesnt happen on the indian ones!
Oh Well you buy things that are supposed to be compatable (instruction even state it and the ways to set therm up) And when you put them together they dont work.
all mods in the instruction where checked at time of fitting too!
Thats another 70 quid wasted on lambretta parts I think this is becoming an expensive
research and development problem for us people that are buying the goods sold by suppliers to make our scooters more reliable.
as usual out of pocket and sick of buying problem parts.

Surely its only an alignment problem involving the crossed over Magnets and the pickup basicly a height issue with the stator... Or is there now another problem that I am not aware of... If its a height issue mark the magnets and pickup lminates with tipex and reassemble the differance can be seen through the apatures in the flywheel then fix by raising the stator (another mag gasket has worked in the past) or lowering the stator by having the mag housing machined by a reputable dealer (There are some on here you know) 
... Hope you can fix it without spending too much more...
... Hope you can fix it without spending too much more...yeah you are right jims but im getting sick of fettling things when we shouldn't have to!
Im gona take a look at it over the next couple of days and if I cant sort it im going to buy a lightened indian flywheel and probs have the same problems.
It funny how it has only just started to happen and has been ok till now you would think once out of alignment then always out of alignment until fettled!
Suppliers seem to be hiding behind the excuses that things that dont work together need to be sorted by the customer not the manufacturer.
dont get me wrong im not having a go at MB I think they have good bits and good service .
Its the fact that manufacturers dont take all parts into account when building bits for us .
Is it just me or do others think we should be getting stuff already done when we pay the kind of money we lay out for these parts.

I have seen the new improved BGM black ignition pick-ups. Not saying that this is your problem but if they are making better versions of the pick-ups then something wasn't perfect to begin with.
Have you rechecked your timing with a strobe? Have you tested your HT cap, lead, CDI, coil or pickup? How would BGM account for the ever changing quality and alignment of AF flywheels?
If it's a fitment issue, the second paragraph of the instruction booklet spells it out pretty well - "Lambretta electronic ignitions have now been made in various countries by a number of different companies. Small differences between flywheels means that is is not possible to have a one-fits-all" stator solution, so some minor modifications may be required."
Knowing that people would be trying to fit different flywheels, BGM have covered the most common fitment problems/solutions in the booklet. AF flywheels however seem to vary in spec from batch to batch. Some have success, some do not. The BGM stator is designed as a direct replacement for an SIL stator - an SIL stator is designed to fit an SIL flywheel (by far the most common setup out there). Any variation in that and the term "fettling may be required" comes into play. I'm not sure how one could make a product that accounts for all manufacturer variations, quality variations, and variation in installation/timing techniques.
I assure you there are no excuses coming from BGM. If there are consistent and verifiable issues they will address the problems as they have in the past (the one time there was a problem). The commitment to quality is there without a doubt. Work with MB on a solution, they won't let you down.

my fly wheel sheered clean off ,i had messed about trying to get it to clear ,also knacked the stator as well ,mainly when i had to weld the puller on.
to get the rest off the crank.

anyone can buy a dremel, but does that make them a scooter tuner
Mark H im not slating the Bgm staor or Mb ! Im just saying that parts should all be made to within a certain tolerance so that they work with other parts on the market.
Im happy with the build quality of the BGM product and normaly quite happy to play about with things until they work as thats what happens with Lambretta parts.
You seem to think I just bolted it on and off I went. Well I got to say I spent a few hours setting it up with the instructions at hand (MB Disc and a good strobe) and it worked fine for at least 150 miles.
We spend a lot of money on these things only to have to sort out problems.
The basic fundamentals of engineering is to work within tolerances to achieve a good working product and I agree Af flywheels seem to be hit and miss. Thats my hole point why doesnt everyone work to the same spec and tolerances when making something to improve our scoots
reliability.
You dont get to look at the instructions on a product before you buy it so therefore I missed the fact that if I buy a lightened indian one I will probs not have a problem so spent 70 quid on an AF light instead and now either have to loose money or try and sort it!
If BGM have built it to spec of an indian flywheel then they should be advertised to go with that flywheel. If they dont work with an AF one as it seems they dont from what I have been told then we should be warned of this!
