Hello all,



I have a 99 TW200 that reads 9/99 on the handle bars and the vin number reads a 2000 model. My question is would a pulser coil from a 01 or 02 TW work on my bike?

operose would probably know the answer to that.

Have you looked to see if the part numbers are the same in the catalouge?

my guess would be yes as pulser coil is simple and only used for timming, but as the electrics changed between those years it might not. check part numbers.

Here are the part #'s from www.stadiumyamaha.com 2YG-85580-M0-00 <---99 4JG-85580-01-00 <---01 4JG-85580-01-00 <---02 I looked at a stator for a 01 and 02 and the wire diagram looks different but the wire diagram for the pulser coil looks the same as my 99. reason i ask is the pulser coil for my 99 is $100 and the one for the 01/02 are $40.

Hmmn would apear they are different then. You could also check new manual resistance specs against old. I think the CDI post on general disusion forum has many pics of the pre 2000 and in the technical forum i posted pics of a 2003 pulsar coil.

my advice is if you can afford it get the correct one. if it has different the cdi might not recognise the pulse otherwise.

anyone else know????

This is why we need better resources regarding the electrical system changes between years and what that means for the average joe, operose, or sirsmighty.



If we had a reliable manual for each year range it would be a start. As it is, working from a manual for an 87 with a post-'01 "supplement" leaves you guessing if working on the electrical system of an in between bike. I know a guy with a bootleg manual that may become available at some point...



I cannot say for sure whether the pulser coil from a newer bike will or will not work, but do know that most places don't take returns on electrical parts so keep that in mind

Hey guys,



I just called my local yamaha dealer they said that part would switch out but the stator wouldn't. so i am going to order this part and i will let you guys know what the outcome is. Thanks for your help!

Parts should be here within a few days, hoping for a good outcome. with the money i saved i ordered a few odd and end parts i was needing. I called a few different shops even the placed i ordered the pulser coil from and asked if the 01 pulser coil would work on my 99 they all said that it would. But i still don't understand the price difference. the 01 i ordered was $40 and the one for my bike is $75. I guess we will see, I will post what happens.

I didn't know you could buy the pulser coil separately. When mine went, I had to buy the entire stator ass'y because the pulser was welded to it!

Did I mention that I also broke off a screw in the housing while doing this?

That was another $40 to have it removed and heli-coiled.



Live and learn...at least these bikes are fairly easy to repair.

Hey all,



Got all my parts in but STILL no start, I think i am having problems timing the bike, i have the manual downloaded but still not 110% sure how to do it. if anyone could lead me in the right direction would be great.

I have the bike at TDC, The cam is lining up with the arrow on the head and the T is lining up with the crank. I have hooked the bike to a car battery trying to start and still nothing, i guess i will try to roll it off see if it will start like that.

What lead you to initially think the pulser coil was the issue?



It sounds like the timing is correct, but I am not looking at the manual, and am new to motorcycles but not engines. I purposely moved my timing chain a tooth and the bike still started and ran ok. As long as you are not 180degrees off or something it sounds like you need to check elsewhere.



Let's begin with the initial symptoms and what diagnosis was done that led to purchase of pulser coil. We can figure this out without you buying parts you don't need it will just take some time.



Did it just not start one day or did you buy it like this? Have you pulled the plug to verify it is sparking when connected to the charger using electric start to crank bike?

I got the bike like this, I redone the whole top end on the bike and while i was replacing the timing chain i noticed the pulser coil was burnt "the white wire was burnt in half" I have bought a new coil/spark plug i am getting good blue spark just no start, How does one know if the bike is out 180 turn?

Would the bike spark at all if the stator was bad? Plus i noticed the kick stand acts as a killswitch would cutting the wire and wiring it together make the bike not start also?

If the ignition source coil on the stator were bad you would be getting weak spark or no spark.



Simple internal combustion engines only need three things to run, and those are air, fuel, and spark. Since you have verified that it is sparking, I would check that it is getting fuel properly.



You may also want to read over the timing procedure again to be sure that the engine is properly at TDC and that everything is lined up properly. Maybe ask lizrdbrth about his timing light setup.



Have you rebuilt/cleaned the carb? If it was sitting like this for a while it might be all gunked up and not getting fuel properly

I think i have more problems then what i thought, i went to pull the bike off today and popped the clutch and the bike just free rolled with just a little resistance thinking either the clutches are bad or the trans need rebuilt :/
