DT125/175MX CDi units

[Speedshop]

We now have new CDi units for the later DT125/175MX models (G&H) available. These have just a brown wire from the generator and not brown and red to power the box. We are well aware that you can buy these on eBay for much less. However many customers have come to us asking if we made one as they eBay ones don't seem to work well, with mis firing or holding back being common complaints.

The reason for this is very clear when you compare the Yamaha DT timing curve compared with the eBay units. If you go to our website and open up the CDi unit product, one of the pictures shows you the Yamaha timing compared to the cheapy unbranded box.

The eBay box is actually a generic moped unit which by chance works on the DT. As you can see it retards back 5 degrees from base and holds back engine performance - which is what you want on a moped, the Yamaha curve gives 7 degrees advance on top of the base timing figure.

I'm sure they will be a few people say they have the cheap one and the bike runs fine. You are welcome to bring it to us and we will put it through its paces on our test bed and see where the timing is. I'd bet a pound every time the timing would be nothing like the proper Yamaha box. We even have a trial unit here that you could fit to your bike and compare the difference in performance. So far people have not be able to believe how much better the bike is with our unit. (Of course if you like the difference you have to buy it - its not a freeby!)

We have a DT generator that we can run to over 10,000 off the bike in our workshops and check the timing on:
