Back by popular demand! Our DT360/400
"Pulser-less" CDi/pick-up repair
The problem: The B & C models of the 360/400 DTs have a black plastic pick-up that is no longer obtainable. The problem is further complicated by the fact that neither the pick-up nor the CDi were a good design to start with, both are known to cause problems and its extremely difficult to tell what is causing the problem. This is why we will not supply a direct replacement CDi unit - too many times the pick-up is at fault which causes a lot of dissatisfaction with customers who've just bought a new CDi which now cannot be returned as its been fitted to a faulty system, plus you still have to find a rare and expensive part!
The solution: Rex's offer a "pulser-less" type of CDi unit that does away with the this troublesome pick-up. The advantage of doing so is twofold, first you get a new CDi unit and secondly you're no longer under the cloud of pick-up failure, so you can enjoy riding without that worry. No other changes to the charging or electrical system are needed, even the HT coils stays the same!
The down side it can be tricky to set up and you need the back plate of the generator machined to elongate the adjustment slots. If you can do this and don't mind setting the timing with a strobe lamp this is an extremely neat solution.
We offer the export kit for sale in our shop, this comes with the CDi, a timing index and full instructions for the work to be done in a local machine shop. The machining needed is so simple could be done with a pillar drill or round file by a resourceful and skilled person, if you send your generator to us we would do it on the milling machine. The export kit is £99.95, if you send us your generator we charge an additional £40+VAT to machine the slots and remove the troublesome pick-up.
(We are working on our 12 volt replacement electronic ignition kit for these machines, this is a complete up-grade and will be available later in 2017. New kits will feature no timing to adjust, single curve systems and optional handle bar switch selectable timing curves. They will be available in ignition only and 12 volt lighting versions)

We are currently looking for running DT250/360/400 machines in standard trim to carry out final testing and fitting checks of the next generation of electronic ignition & 12 volt conversion kits.
The next generation of kits bolt straight on, with no ignition timing to set up. The purpose of this excersise is to check the fitting on as many different models as possible.
We are looking for bikes with points and factory CDi. Owners must be able to deliver them to our workshops and collect them prompty once the checks are done. Owners who assist will recieve a basic system free of charge.
