DT125R FORUM

Hi, i am john from the UK and I am the owner of a 2004/05 Yamaha DT 125 RE. The bike is low mileage at 11,300 miles but unfortunately after being stored for a long time it is now a non runner. With the help from the forum members I hope to get it running again. Wish me luck. Thanks to Calum and HOTSHOT III for their help so far.

Hi Calum, the OEM coil I ordered has arrived from Fowlers but the clear autolube pipe I ordered from e bay has not arrived. It is showing as running late when I check the tracking. I do not want to start the bike until the clear oil tube is fitted and bled so I am at the mercy of Royal Mail. Assuming the bike will run the only thing left to do is a couple of bulbs and then it should be ready for its MOT. I will fit a new plug cap similar to the one you show.

Hi Calum that is the one I saw but I decided to play safe and get the OEM one from Fowlers. It would be interesting to see if anyone has tried one of these and if it worked ok or not. I also looked at buying a new plug cap from Fowlers but they do not stock them any more but at 32 quid I would not have bought one anyway.

HI HOTSHOT III, I probably will go the OEM route, I just want to explore all the options. I was wondering if there is a test for the input voltage to the coil. I haven't seen anything.

Thanks HOTSHOT III I will fit the clear tube kit as you suggested. When I looked on yambits for the pipe kit I looked to see if they had coils as well and they had two. One was £18.00 and the other was a Japanese one made by Mitsubishi for £40. Do you know if the Mitsubishi one is as good as the OEM one from Fowlers.

HOTSHOT III thanks for the reply. I am pretty sure the coil is knackered. I tested it with the multimeter and got a reading of .0005 ohm on the primary and nothing at all on the secondary so I think the coil and the plug lead/cap are both knackered. There are a few little jobs that need doing but I do not want to spend money on them until I get it running. I am going to price one up at Fowlers as you suggested. The last time I started the bike it ran for about 20 minutes and was idling nicely as it always did then it cut out and would not start. I still had spark then. I took the carb off and cleaned it but did not find anything wrong and then the battery died and it has not been started since so I need a spark to see if the carb is ok. The bike has only done 11,300 miles and is in generally good order so I hope I can get it running again. I was planning to MOT the bike then sell it but I might change my mind and keep it. Just checked Fowlers but they are out of stock.
