?? Added flywheel weight to 2003 EC200, bike ran for test ride now wont start
- Thread starter mswilkes
- Start date
Correct, all i did was remove the stock nut from the fly wheel, screw on the weight and and new nut to torqued specifications. Cranked the bike right up and went for a ride. I will confirm the spark when i get back into town. I belie i do though because after 15 good kicks it fires a nice plume of smoke out with a little pop like it wants to start.
If that is the case, does the flywheel get pulled to see if its broken or is there a trick.
Really need help now!
I pulled the sprak plug and confirmed a bright blue fat spark. I then pulled the fly wheel off and it appears the key is in good shape. Unless some one can confirm, after looking at the pic, that the key has been sheered i guess i will need to move on to the next idea. Any help is much appreciated. My next thought is tho just redo the timing since i have everything pulled off...any ideas.

That is what the key is supposed to look like. + if you a good blue spark then ignition isn't your issue. Wise to look at the 'last thing you worked on' first though. I'd look at a fuel issue or check compression. Any history on top end service? Low compression is a no-no on a 2 stroke starting
A run down
I have rebuilt the carb twice and it is recieving fuel properly. When i pull the plug after kicking it 10 to 15 times it is wet without an buildup, for some reason it just wont fire. On the 10th to 15th kick the bike does a nice big puff of smoke si i believe that combined with how it feels, tells me i have good compression.
The bike has always run perfect untill i added the flywheel weight, it ran for 1 trip throught he neighborhood then would not restart.
The only other thing i kinda messed with was the green kill swtich wire. It was not running to anything so i clipped it a little shorter to hide it. I think the green is the ground.
In reagrds to the kill switch, it worked fine as it was because i always use it to cut the bike off. The only thing i can think is..maybe the green wire was connected to the black kill switch wire i a loop somehow. I have not troied to rewire it this way, when i was trouble shooting this as a possible issue i just unplugged the kill switch all together. Any thoughts.

There's alot of dirt on that main bearing seal and possibly oil. The dirt can damage the seal lips, causing an air leak. Is there any up / down movement in the crank bearings ?
Just got done checking it and there is no play, i cleaned up the dirt though. I have re installed the flywheel and it does not start. How do you bypass the yellow/black kill switch wire from the CDI. I am wondering if this is the issue.
I am at a lost
So, I have checked the timing and its correct. If you have read the prior posts, i have tried everything. Keeping in mind the bike ran perfect and shut off properly then when i went to start it 4 or 5 days later it would not start. The only thing i did was trim the green wire from the kill switch back because it wasn't connected to anything. I have looked at the CDI and the only other thing that seems odd (although it must have been this way all along) is there is a yellow wire that does not have anything plugged into it. This yellow wire is coming from the bundle of wires out of the flywheel case beside the magnito.:mad

Yellow wires are your 12V. If all you have done is something with the green wire then try and undo it. I went through the wiring on mine not long ago and I think I recall the same on mine. I unplugged a wire that I thought went nowhere. I'm sure it only resulted in the kill switch not working until I earthed it again. I think..
www.gasgasmotos.es - download the manual for your year and pull up the wiring diagram. It helps!

The green wire was already unplugged prior to the issues starting, so i actually did not change it. This one may have to go to the local mechanic.
Just got checking them and still a no go.
Yea, I unplugged it from the CDI and still nothing. The spark looked good.
if you have spark then the problem isn't the kill switch wires (they kill the spark
) and won't be any other wire issues either. Keyway is a good clue it isn't a timing issue.
The only other thing is fuel/compression.
Is the plug getting wet after you have been trying to start it? Not wet = no fuel.
If the plug isn't wet try laying the bike on its side until fuel dribbles from the overflow then try to start it.
Next is to check the rings to see if they have stuck. My kid burned his rings (polite way to say he melted things) and the bike still felt like it had compression when trying to start it but wouldn't even pop.
