Hi All - firstly thanks to Andy for explaining the powervalve scenario to me and also to all contibutors on this forum, whose old posts I have been reading up on. Have been staring at Nev's loom map for some time now. I fear that I am going to be asking a lot of questions on here and am not yet in a position to offer any help myself....
My project involves the use of a 1993 DT125R engine, which is going to be transplanted into a much much older bike (1955) - as such I am going to have to make up a new loom to link the engine to the bike. This is confusing and worrying me. My project bike would have originally had a very very simple loom as it has no indicators, no sidestand (switch), no electrical guages (no tacho, no speedo, no temp, no fuel gauge.....).
The only electrical features that the bike will have are headlight (high/low), rear light and brake light. I am struggling to fathom out how I am going to work this in terms of the dt125 engine, the cdi for which I have has 10 or so wires coming from it, a lot of which seem to be interdependent - ie originally the sidestand switch would be linked to the cdi, the ypvs servo is linked to the cdi, reed switch for rev limiter linked to dci etc etc.
Can anyone with a good level of knowledge of the electrical niceties of the dt125r help me by explaining how to use the cdi connections in their most stripped back basic form to work in such a simple chassis - so many wires, it is frying my brain.... I suppose that if a dt were rebuilt as a basic farm hack, the priciples might be similar
Ooo wow. Get a project thread up mate with lots of photos. Be very interested to see how this progresses. On my brothers 2001 DTR he had some sort of electrical fault. So he wired up the cdi to the engine. On the old dt's the engine runs off the engine so he had lights. That's what you'll need to do to start with. Just purely wire up the cdi and the engine. No kill switch or ignition for the time being. That'll at least let you know what you've got to work with.
Just checked out your project thread in the other forum Swallow, wow you have a job and a half in front of you there mate, but I reckon it will look the dogs when its finished, I don't know how much you want to keep it as standard, but looking at the front steering leg, I reckon you should have a look at the Peugeot Speedfight ones, I've built a couple for my lad, and I reckon it would be better to use one off a Speedfight as you'll have proper disc brakes and a proper spring instead of that rubber band do dah,especially if you're putting in an engine that will potentially hit around 80 mph, as for the loom, you'll really need to work out what you actually want to end up working on your scoot, then take it from there, I'll help where I can,
looking at your link . I would just stick with the standard dtr loom could easy be wired to any lights you fit batter could be hidden away and ignitin again could be modded and hidden with nothing but the top showing .
same for the clocks you could wire or mod many types of clocks to fit the loom .
looks a intresting and fun build myself would have gone down the scooter engine and back wheel route maybe from a Gilera Runner .
hows you gona go about the gear lever and changing gears .
