Hi Bill, thanks again for your help and support, I may well be able to find a rolling road set up near me but on previous investigation the comment was where do we plug in the laptop how will we flash the ignition? Its a problem with a 40 + year old machine and then as you say its getting it there, ...

I think you are misunderstanding me - I make no mention of people on this forum, those I refer to have been commercial operations and outside of any Morini circles. I have received much help and information from those on this site such as Paul Compton and others and the Dutch Morini site. I would ag...

Hi Bill, yes its a problem, I looked at widening the slots in the back plate to give more advance but there would be little advantage as the ears will then touch the timing belt, Fodone are a major supplier of electronics in Italy but are mainly trade so we do not hear much about them, I will ask An...

Well Bill, no cure for the problem then, regardless of all the experts. I don't know where to go from here with mine, it starts and ticks-over as I said before but is reluctant to rev and shows about 30 degrees retarded. It seems no one can offer a solution to this problem, although there are 125H's...

Hello,
does anyone out there have one of the original black transducers part number 323921 in working order that I can borrow?

Hello all,

does anyone out there have an original black transducer in working order number 323921 that I can borrow?

Thanks Bill, I look forward with much interest to see if you have found the Holy Grail to the 125H problem. Think I must have been bad in a previous life, not only does the 125H not run but we noticed last week that a large blister had appeared on the recently painted petrol tank, which may well now...

Hi Bill, anymore update on your ignition repairs, I have finally gotten my 125H to tick - over (I did not really believe in miracles) but if I apply much more throttle it will stop again, I have used a timing light and the PMS mark lines up with the centre camshaft, however the ANT mark does not mov...

I am sure someone somewhere could produce a decent ignition system for the 125H, I researched this and there are hundreds out there, mainly for motor scooters (some are made in China) the now defunct NLM had a kit for the V twins and Rex Caunt Racing in Leicester has one for the BSA Bantam. I am sti...

Hello Bill, yes the expense is always a problem, my restoration went well over budget and it still does not work the engine modifications you mention would not be worth it at all, unless you were going for some sort of 125cc land speed record! I am getting to the stage where I think - should have bo...

I am surprised that no one makes or can offer an ignition unit for the 125H having a searched around there are hundreds of them for all manner of lightweight scooters and bikes, some made in China but don't know about the quality. I suppose due to the scarcity of the 125H no one can make the units a...

I contacted Kennedy but he says they no longer do it for the 125H I suspect they were selling the VAPE unit which is no longer made.

Hello Bill, thanks fore the info, I think that's how I have set it up but will check again. tell me one thing though - with your 125H if you align the top mark on the crankcase the one at 12 o'clock with the punch dot on the cam wheel and the mark on the crankshaft pulley with the crank case mark at...

can anyone give me some pointers on valve timing, I noted today that my 125H is blowing petrol/vapour out through the carburettor inlet. I may have set this up wrongly, after the rebuild. I have fitted the cam wheel it can only go on in one position as its keyed onto the camshaft, then turning the t...
