Aye Tom, Thank you for your informative reply. Leonard over here in the UK had his entire ignition system examined, re-wired and the polarity changed by a man, Tony Tambs, "Scootronics", which was successful in enabling the ignition to advance at ~1,250 rpm and for the engine to be able to...

GOOGLE TRANSLATION: Aye Tom, Mag ik vragen of je ervaring hebt met het verkrijgen van een 125H ontstekingssysteem om de ontstekingstiming te vervroegen? Of alternatieve vervangingen? De VAPE/Power Ignition en HorsePowerIgnition vervangingen zijn niet langer beschikbaar! Ik begrijp dat het onwaarschi...

Aye Julian,

£500 or Offers. I was tempted, but with other "black holes" in the workshop, I resisted the temptation, this time.

Good health, Bill

Aye Julian, My pleasure and beware the 125H ignition hex! :evil: Leonard (125H) has his running now after modification to the polarity of the ignition trigger coil wiring, having had the old trigger coil fail and replaced, with a new one. The same man modified mine in the same way and for the same r...

Really? :shock: my local bike shop's mechanic happily and repeatedly pumped up my front tyre to over 110 psi (7.5 bar) to convince the bead to seat, There really is a "42 Carat .......!" When trying to seat the bead into the wheel rims of my 125H the tyre fitter (BSB experience) took the H...

Aye Leonard, My apologies for lowering the mood, but after another day of checking the valve timing, checking the ignition timing and swapping my 2 CDI modules over, I still have an engine that starts, runs roughly at a fast tick-over and as soon as the the throttle is opened, cuts out! :evil: :evil...

In response to my own question in my previous post on this thread: Was going to time my 125H up tonight, took the valve cover off to ensure TDC, then popped a 17mm ring spanner on the end of the cam and gently eased the engine in a clockwise direction and it produced a loud "CLACK" noise f...

Aye Leonard, I hope that you repair and have no lasting complications. The expense of sorting out the damage doesn't sound good, but I hope that you can achieve the quality that you had before the fall. As for the .......... :evil: :evil: :evil: cyclist, I'll no pass comment on this public forum! Wa...

Aye Leonard, Thank you for your enquiring message. No, I haven't lifted the cover on the carcass, as I have been wearing out and maintaining my other bikes, as well as rebuilding a Ducati 350 MKIII engine. I really should give it a try, as per your excellent instructions and see what happens! Hopefu...

Aye Leonard, Thank you for your quick reply. I am sorry to read of your two family bereavments and well aware of the resulting glut of formalities to be completed in triplicate. Having spoken with Tony today, it wasn't until he had done some research before your arrival that he thought polarity migh...

Aye Leonard, After my having received my whole ignition system back from Tony (Scootronics) last September 2022 and the ignition advance problem remaining unresolved, the bike was shunted to the back of the workshop and a cover drawn over the whole debacle! :evil: Today, quite on the spur of the mom...

Aye Arthur,

Nice to view the progress.

You'll have it running afore I get 'The Minx' ('79 125H) running and a damn sight more cheaply I suspect!

Good health, BillR

Aye Paul, thank you for your posting and the attachment. I think that I understand that this article explains how the CDI adjusts the timing, according to the volts that it receives from the trigger coil and not the low tension power supply coil. The figure given is written as " 1,38V ". I...

Aye Leonard,

Nigel certainly knows his stuff and good to hear his take on the problem.

However, your final sentence sums up my thoughts at present.

Good health, Bill

Aye Leonard, is the "Horse Power" that you refer to this company? Link: HPI_Belgium I purchased an ignition from them for the Ducati 450 MKIII and couldn't get it to generate a spark! As I had purchased two years before installing the system, any warranty was null and void, so it sits forl...
