i am back -- ? after about a week of working on stuff i COULD fix i am now back to this rev3 which still will not start.. i truly appreciate all the ideas and suggestions but so far no good has resulted.. wiring from stator and test as follows ---yellow to stator base =.7 ohm----brown to stator base =.4 ohm-----red to stator base =474 ohm---red to brown=474 ohm---white to stator base =202ohm-- white/black tracer to stator bace =203 ohm... white and white/black seem to be trigger coils and both are either good or bad -- but i still have great spark just at the wrong time -- and flywheel key is fine and shows no sign of ever been sheared -- so --- i am still at a loss and am losing hair rapidly

if only i could run away or look extremely busy LOL... specs for this bike seem to be either totally hard to find or non existant... with the few specs i can find everything checks out .. to the best of my knowledge there is no reliable test for the cdi box .. the puzzling thing to me is that the ignition generates GREAT spark , it is just at the totally wrong time .. i have only ever seen this situation if the flywheel key was sheared and this is not the case here ... there are many posts on this site about faulty stators but everyone says the pickup coils are the problem .. and if that were the case i don't think i would have spark ... so i am at a complete loss to explain

thanks very much for the insight -- i have not run into this before --admit i have worked on very few beta trials bikes .. next question : i see a few places in the UK that offer rewind services for this stator does anyone know of a place in the US that does this sort of work ??

i understand that these motorcycles have many stator issues -- i guess my question is .. could a bad stator still generate good spark and just cause the timing to be so far off ?? as i have said when testing with a timing light it seems that the spark occurs at about 90 degrees after TDC

and i would sat the timing is -90 -- firing seems to be about 90 after tdc ... exhaust port is open

well the base has been moved but there is no way for it to be moved that far ... it could be the pickup issue but since there are 2 i am not sure --i have been a motorcycle mechanic for many years and haven't seen this situation before .. and the wiring seems fine -- no cuts or broken wires .. and all tests good according to the specs i can find --

i would agree -- but i have removed the flywheel and the key is fine -- and shows no sign of ever being sheared -- therefore i am at a loss

that was my initial thought -- however the key is fine ... it acts as though the magnets have shifted inside the flywheel but i don't think that is possible..in all the years i have been doing this i have never seen that happen without the flywheel being destroyed.. thanks for the thought though

customer bike --2000 beta rev 3 -- good spark -good compression -clean carb -- ignition timing seems WAY off --like 90 degrees after tdc when i check with a timing light -- any thoughts would be greatly appreciated
