c) Setting your ignition timingc) Setting your ignition timingThere are several ways to set your ignition timing. For a bullet proof way have a look at page 55 of Scooter Center‘s Lambretta catalogue. For a free download visit:www.scooter-center.com/html/download.htm.

Never assume just by fi tting a new stator plate in the same position as the old one that your ignition timing will be exactly the same. Werecommend that you go through the full ignition timing routine when fi tting a new stator but if you have changed the stator plate only and you are 100% sure that the markings on your fl ywheel and mag housing are correct then you can use these to setyour timing. Now check that the two lines of the pick up are sitting fl ush with the two lines at the fl ywheel when the arrow of the fl ywheel points to the marking of yourignition timing. Once you are happy that your timing is set correctly then it is a good idea to mark the position of the new stator in the mag housing so that it can be refi ttedwithout re-setting the timing in future.

Be careful not to squeeze the cables anywhere. Don‘t forget to fi t the standard securingplate that holds the wires away from the fl ywheel. Check that everything is fl ush and nothing rubs. Once everything is fi ne, take the fl ywheel off and tighten the nuts of the stator plate. If you are using a torque wrench the setting is 6-7 Nm. Now refi t the fl ywheel with a torque setting of 68-75 Nm. Refi t all the cowls and you should be ready to go!

BGM STATOR PLATE – LAMBRETTA Congratulations for purchasing the bgm stator plate for your electronic ignition! We wish you many miles of trouble free riding using this stator, and would like to advise you how to fi t it properly. First of all there are a few simple things that you should bear in mind when fi tting the stator plate.Lambretta electronic ignitions have now been made in various countries by a number of differentcompanies. Small differences between the fl y-wheels mean that it is not possible to have a ‘one-fi ts-all’ stator solution, so some minor mo-difi cations may be required. While fi tting, always check that everything turns freely and nothing is rubbing. The most important things to check are: • Will the fl ywheel rub on the studs, nuts or bolts of your mag mag housing? With some fl ywheels (e.g. AF) this can be a problem. The solutions are togrind down the heads of the stator securing bolts like those originally supplied with the AF ignition kit or machine the back of the fl ywheel in a lathe to obtain clearance.

• Will the fl ywheel rub on the pickup coil of the stator plate? Check for this by putting two layers of gaffertape on top of the pick up. Test fi t and turn thefl ywheel, and then remove it to see if the tape has been rubbed. If it hasn‘t then the fl ywheel should begood to fi t as it is. If it has rubbed then either the mag housing or stator needs to be modifi ed.

When fi tting the stator plate to an AF fl ywheel then follow instruction a), if you are going to fi t it to an Indian fl ywheel follow instruction b).

a) Fitting with AF fl ywheela) Fitting with AF fl ywheelSometimes you will fi nd clearance problems of the pick up with an lightened AF fl ywheel. The traditi-onal solution was to machine back the inside face of the mag housing that the stator plate sits on, to allow the stator to sit deeper. If you are going to fi t the bgm stator plate to an already machined mag housing it should fi t straight away.

There are two popular solutions to this problem:

• Put the mag housing in a lathe and machine the inner face back by approximately 1 mm.

• A more convenient way is to remove the screw which holds the pick up and take it out of the way. Now take a grinder (a cutting disc on a Dremel is ideal) or a small saw and cut away the top two laminates (the sandwiched steel plates) so the pick up can sit lower. Check that the pick up sits fl ush and then refi t it. Ensure that the pick up is refi tted straight and securely by putting Loctite-type screw lock (e.g. Scooter Center item number 3600008) on the retaining screw and underneath the pick up. If you achieved the desired clearance, you are ready to re-adjust your ignition timing. Now move on to section c) for adjusting your ignition timing.

b) Fitting with the Indian fl ywheelb) Fitting with the Indian fl ywheelThe Indian design of fl ywheel has more clearance to the pick up, so this stator should be a straight replacement. It is still wise to check the clearance of fl ywheel to pick up as well as the clearance of the fl ywheel to bolts, nuts and/or studs of your mag housing. If there is nothing that rubs, you are ready to re-adjust your ignition timing. Now move on to section c) for adjusting your ignition timing.
