No spark :(
-
I was riding, ran like normal, and suddenly the bike started sputtering and it stopped, i got it home, and checked everything. The plug looked fine, it sparked good in my friends bike. I checked the coil and the wire for the spark plug cap for resistance, and it was fine. When i turn the key on it makes a spark at the plug, but when i turn the engine over it does not give any spark.
Even though im not experienced with these kind of problems, it seems pretty weird that the bike shut off like that with nothing indicating it any suggestions

It's just a microswitch on the clutch lever that won't allow you to press the starter motor whilst in gear without the clutch engaged.
It's only on the RE models. It would only affect the bike if it wasn't in neutral and/or only if you were using the starter motor. And IIRC it actually stops you pressing the starter, not spark.
Does it start on a bump?
-
@Calum yup, but the bike worked like that for a long time so i dont really see them as problems anymore
Ive checked the coil, and there is no elecricity going into it, but i ohmed it and it seemed fine. So i guess the problem is either a wiring issue between the cdi and the coil, or the cdi itself, right?

Can't beat that kind of easy repair even though they can be an arse to find

@bananper , Can you remember which wire? I've got no spark on a bare HT lead on my son's 2005 DT125X.
He has only been riding the bike for about a month. He said 2 days ago the bike became hard to start from cold (normally fires up straight away).
Now it won't start. Have tried bypassing the side stand and clutch switch by using a paper clip on the block connectors.

You see where the clutch cable connects to the engine? There is a little bundle of wires coming out there? These need to be checked for continuity.
Also check the wire to the coil. Also ones around the CDI unit...Can’t really help any more. My wiring is 2 generations before yours!. Good luck...
PS have you wd40’d your ignition barrel!
Give it a good wash and turn the key back n forth -
@spookdog , so far I've just tried disconnecting the clutch and sidestand switches and using a paperclip on the loom block connector. Motor spins over fine but have no spark from the HT coil. If the ignition switch was at fault would the motor spin over on the electric start?
My son has only been riding the bike about two months. Bike was always a first time starter. He tells me that on Wednesday the bike became hard to start from cold. I saw him struggle to get her fired up on Friday morning but he needed to get to work so was rushing. He drove the bike to work but Friday evening it wouldn't start after work. So as things stand it's got no spark on a bare HT coil lead.

@crispy Bridging the connectors with a paper clip isn't the way to solve the problem.
Fix the side stand/clutch switch rather than bridging. 9/10 when I see this problem it's the side stand switch and bypassing it doesn't work as it's done incorrectly.
-
@calum , The activation pin for the side stand is moving smoothly in and out, so it's physically working fine. Do you know what reading I should be getting on the single wire feed onto the HT Coil, just so I cake see if I have a feed (power) going into it?
I've got a basic multimeter and set it to 200ohms and have checked the three white wires coming out of the alternator and have an reading of 1.1 across all three wires.

@crispy
Just see if there’s any voltage at all going to it. I’m gonna hazard a guess about 12v?...As to the ignition barrel? I don’t know about RE wiring, there are many connectors inside. On my bike just disconnecting the block allowed the bike to spark

@spookdog , bike turns over on the electric start. I didn't think it would turn over if the switches were giving grief. Weirdly the ignition switch seems to go straight into the loom. No sign of a block connector. Mounting bolts for the ignition are those "special" Allen bolts with a nipple in the middle to stop You using an ordinary 5mm Allen key.
