Tallpaulself Posted April 15, 2023 Report Share Posted April 15, 2023 (edited) Hi all. I've a 97 beta techno Dougie Lampkin replica which I bought for a decent price as it had no spark. This bike has a separate CDI to the coil and original coil is a blue Ducati one with only two wires, a live feed and an earth. I managed to get a spark with this set up however the wires entering the coil are on their last legs. I've also a (newer?) Coil pack with integrated CDI, the one with 4 spade connectors and an earth wire. 2 green, 1 red and 1 white inputs. If I were to use this instead, is it as simple as doing away with the stand alone CDI and taking the green, red and white wires from the stator straight to this newer CDI/coil? The yellow would remain going to the cooling system. This only leaves the black wire from stator left. Any info on what this does greatly received. Apologies if this all seems stupid or obvious. I'm new to motorbike wiring. Thanks Edited April 15, 2023 by Tallpaulself Typos Quote Link to comment Share on other sites More sharing options...
mcman56 Posted April 17, 2023 Report Share Posted April 17, 2023 (edited) Not really answering your question but I aren't all coils for CDIs similar? Could you use a pit bike coil? IIRC, there are inductive (battery powered) and capacitive discharge ignition coils and they have different resistance values. You could measure to compare. What brand is the stator?

What brand is the stator? This is what I ended up doing. It dawned on me yesterday that I had a spare coil for my son's 49cc Chinese quad. Hooked it up and bingo, a decent spark. Now to move on to timing/check Woodruff key as it's only turning a few times and kicking back like a good un Quote Link to comment Share on other sites More sharing options...
mcman56 Posted April 17, 2023 Report Share Posted April 17, 2023 I'm not sure if this helps but I had a Techno and it was likely a 1997. I once put a timing light on it and got 6 degrees at idle, 20 at mid range and 25 to 30 at full scream. If the CDI advance stuck at full advance it may kick back. In contrast a 2008 Rev3 200 had 15 degrees BTDC at idle and revved up got 20 degrees I'm not an EE but from my understanding, an ignition with no designed in advance will give you about 5 degrees due to higher generated voltages at higher RPMs making things happen a little quicker.

That's a great help, and thanks! That was going to be the first thing I checked after making sure the woodruff was all ok. I know the stator has been rewound and hasn't seen use since so in theory should be fine Quote Link to comment Share on other sites More sharing options...
reggie Posted April 18, 2023 Report Share Posted April 18, 2023 Beta has an ignition kit for the Technos p/n 007.45.057.80.00 Quote Link to comment Share on other sites More sharing options...

My bike cost me as much as that kit 😲 Quote Link to comment Share on other sites More sharing options...
Tallpaulself Posted April 18, 2023 Author Report Share Posted April 18, 2023 One thing that puzzles me is that my bike has a cdi that's separate from the coil unit. Almost every forum and Google search of coil for this bike brings us a combined CDI/coil in 1 unit. The manual wiring diagram shows that my bike is right as it is. So why does everything point to otherwise? Did beta change to combined unit on later models? Quote Link to comment Share on other sites More sharing options...
mcman56 Posted April 19, 2023 Report Share Posted April 19, 2023 (edited) I don't remember the Techno but there was a CDI/ coil combo replacement for the 2008 Rev3. I bought one as a spare and still have it but have no idea if it would work on a techno. The 2008 Beta came with separate CDI and coil. https://www.hpi.be/item.php?item=CD13201 Edited April 19, 2023 by mcman56 Quote Link to comment Share on other sites More sharing options...
