    heck geo getting info out of you is like trying to get blood out of a stone man! now i see its been rewired somewhere, so you want to rewire it with the right colours (big job) or just get it going again (smaller job) ?
  2. well you are going about it the wrong way kiddo you dont 'NEED' to know where to post an intro and we dont 'NEED' to help you with fixing your scoot, thats how it is in life, it seems you just want to take and give no contribution here in any way...am i right?

    but how can it run with the white/red and brown severed? these are pulser and charge coil wires for ignition
  4. thats a bit abrupt isnt it< its not hard to find!

    i suppose the easiest way would be to repair them and then cover them with adhesive lines heat shrink individually and then tape up the bundle. I am totally confused with your last post though because your bike wouldnt have run at all with some of those wires severed for example the white/red, Brown, Black Read this DT175MX Ignition checks There were two versions of ignition systems on DT175MX bikes. The mk1 version from the earlier bike had a 7 wire CDI the early bikes had a round section swing arm. The mk2 version had a 6 wire CDI, the red wire is absent on these. These bikes have a square section swing arm. The HT cap (AKA spark plug cap) unscrew it off the HT lead, it is supposed to be a resistor cap so should be around 5K Ohms The ignition coil primary...Orange wire to battery neg should be 1 Ohm +- 10% The ignition coil secondary...HT lead to battery neg should be 5900 Ohms +- 20% If the readings are much higher, check the ignition coil has a clean ground connection. Yes and the ignition coil mounting is a wiring harness ground point too, so check its clean and bright there. Disconnect all the wires from the CDI. Then using your multimeter on the loom side of the connectors. Black probe on a clean part of HT coil ground point Red probe on...... Orange, Meter to 200 Ohms, expect 1 Ohm (HT coil primary) Brown, Meter to 2k Ohms, expect 420 Ohms for mk1 and 300 Ohms for mk2 (Magneto charge coil) White/Red, Meter to 200 Ohms, expect 12.4 Ohms for mk1 and 10 Ohms for mk2 (Magneto pulser coil) Red, Meter to 200 Ohms, expect 13.6 Ohms for mk1 only. (Source coil 2 or high speed coil) Black female connector, Meter to 200 Ohms, expect dead short repeat for black male connector Any difference in the results for the two black wires may possibly be rectified by cleaning the front engine mounting bolt and a little of the frame behind the bolt head, then tighten to torque spec. Black/White, Meter to 20K Ohms, with ignition off expect dead short, with key on expect open circuit, with kill operated expect dead short (Engine kill operation)
  6. you have PM Sam

    I too have some questions Did you get the old girl an MOT then? dont remember you saying? its been pissing it down all day here, how about in Brighton? How many wires does your CDI have Geo ? What about those severed wires, how did that happen...what colour are they?

    yeah what Pat says, copy the IMG code and paste it into your forum post, that way we will see it directly. Heck it looks cold in your neck of the woods...must be on its way here soon! its a shame you havent got anything in original blue colour you could have had some mixed from a colour chart at your local motor factors shop It is a DT175E by the way if its a 78 You can download a parts book from the workshop sticky topic 'Parts Manuals for Yamaha Bikes'

  20. Airhead replied to vic-fzr600's post in a topic in The Bar
    if no one here knows ...why not ask first?
  21. greetings tesco boy, 250 sounds a great size, I remember them when they were commonplace Try Fowlers of Bristol, perhaps they could help?
  22. the mosquito was keeping an eye on your fuel consumption yes water in the carb could cause missfire issues without doubt...fingers crossed
  23. Airhead replied to 2 Wheels's post in a topic in Projects
    you could always mask off the brake area and spray with engine/exhaust/bbq black you must have some of this stuff?
  24. Airhead replied to 2 Wheels's post in a topic in Projects
    even if it did stick Pat would it stay? I suppose it depends on how much heat is developed from braking...probably not much I would think with such a light bike
