ive tested every thing i get an input signal all the way from the pick up to the cdi i then get a extremely low voltage out of the cdi to the ignition coil........ 1.2V 2.2V .5V nothing consistent and its same in AC or DC testing

Measure the resistance values when the engine is cold. You don't make any measurements while cranking the engine. ;) Here are the resistance values from the TW200 and XT225 Service Manuals.

Electrical System Resistance Values

Spark plug cap resistance:
Both Yamaha manuals specifiy 10K Ohms

Ignition coil resistance:
Primary Coil: Yamaha XT225 manual specifies 0.56 to 0.84 Ohms
Secondary Coil: Yamaha XT225 manual specifies 5.68K to 8.52K Ohms

Pickup/Pulse Coil Resistance:
Both Yamaha manuals specify 656 to 984 Ohms

Exciter/Charge Coil Resistance:
Yamaha XT225 Manual specifies 584 to 876 Ohms

I suggest you measure the stator/exciter coil resistance once again while the engine is cold. The resistance value you reported seems a bit high. Also, the pickup coil has been know to fail for the TW200 motorcycles. ;)

ok ill try at lunch and btw spud your right accreditation so over rated
looks like the animal i saw under the cover..... http://translate.googleusercontent.c...1wIK7qEpnToXOQ
good news is it looks like the rotor is the same AC or DC http://translate.googleusercontent.c...8svCEbzjDhRjcQ

Yes, that's the correct stator and pickup coil. :) I really don't think you are having any problems with your flywheel (rotor). ;)

so i took the plunge (since i got nothing better to do then play with a tinker toy set) and ordered a set of coils and a rotor might as well re place the wiring harness while I'm at it :P jk but this time i know ill have an ac stator ac box AC coil's all AC i will make this bike run if its the last thing that runs over me!

meh it sat a round a long time and god knows what it went thru before hand if i'm going to swap it might as well swap all of it i need to find some torque figures now i think the TW book has some you showed me

If you decide to change the flywheel, you are going to need a flywheel puller and a flywheel holder. ;)

Indeed, I suggest you study the TW200 Service Manual. It explains all the tools needed, the procedure to follow, and the torque specifications for each bolt. :)

i got the pullers and the holders all ready there main stays for pulling aircraft charging systems
but yea i need to see the book and study it

and fyi a good leather belt and a strong grip makes a good fly wheel holder in a pinch

soooo i come to find my flywheel puller dosnt fit my bike... joy.... any one happen to know what size it is off hand?

Thanks for sharing the good tip. :)

Yes, read post #45 in the following thread. ;)

thanks spud we need assemble a crash kit book on all this ie build a better zong service manual

Most of your ZS250GS engine is identical to the engine in my ZS200GY-2. ;) Therefore, a lot of the threads in the "Zong Sticky" also apply to your bike, Kid. :)

hey good looking out, i was coming to that conclusion but i was a bit slower to the punch i see i was going to start asking about head light wiring since the chump cut the damn plug off the harness.....
