DT125R FORUM

@declan no kick on her so can't measure that way. But with the plug out holding my finger over the hole it certainly spits my finger off with force when I use the starter. Also with the bike in gear it certainly doesn't spin over easily when I physically push it. So don't think compression is the issue.

@calum . I had been asking my son to organise getting the bike into a shop as I was getting nowhere (my head is melted with work so I just hadn't got the patience) and finally he got a breakdown recovery van organised today. So when I was bringing the bike down the side of the house I thought I'll just check again for fun. So it wouldn't start on the button. Turning over quickly so battery strength isn't an issue. But I tried bump starting it and it came to life straight away. Drove up the road and back as far as 4th gear and ran fine. Wouldn't tick over or restart on the button but the motor was turning over as expected.
Bike is gone to Cotters bike shop in Dublin but I thought the bike wouldn't turn over if it was clutch/side stand type of issue.

Does this sound familiar to anyone? Bike spins over on Electric Start and won't start, but will start on a bump?

@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.

@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.

@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.

@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.
