Powerdynamo Taco problem

[AlanJ]

Hi All,
I am sorting out an ignition problem or rather Powerdynamo are, and I must say they have been really good but my problem is how to get a Taco working electronically with this system. I can replace the Taco the Speedo and neutral/ ignition etc. but that's not what a Saxon Tour has so, can anyone give me an idea what to do with this one please. What I am getting at here, has anyone done a manual solution to this problem?
Take care Alan.

Hi All,
I have nearly finished working on my Saxon Tour 301. When I bought it, or rather won it on Ebay it had no sparks but a great thank you to Power Dynamo's generosity and help I now have a running 301. The original taco is electronic and I believe runs at 4 pulses per revolution, ie 4:1 where as the Power Dynamo system runs at 6:1. Question is does anybody know how, or where I can obtain a reducer from 6 to 4 pulses per revolution? I must admit it is a bit of a mystery on the electrics when it comes to this sort of problem, so HELP PLEASE. Take care Alan.

Hi Dave,
Sorry I did not get back to you sooner, thanks for your info, I will look into it and post if I get a result.
Take care Alan.

Hi Dave, I did get with speedshop.com but they pointed out that if they looked at my problem it would likely cost a fair amount, and mentioned that the problem they are working on is into £10,000 so, somehow I don't think I will ask them for help. I have asked powerdynamo but as yet have not received a reply. My Suzuki Burgman 650 goes for MOT tomorrow and then sadly for sale, It's just too heavy and as our forecourt is shingle, it's just so easy to drop it. Thanks for your thoughts Dave, take care Alan.

I reverted to a mechanical revcounter and older speedo, so my 251 now has etz250 clocks. I had to drill a hole in my top yolk to access the ignition key. I prefer the look of the older setup but I had to buy parts but it works now.

Hi Vicar,
Good to hear you got it sorted. I did think of doing the same myself, but you might have read my posts to see that I ended up with 2 Saxon Tour 301's. ! is complete and up and running except the taco and the other is in boxes and I have 2 sets of most parts including the instruments so I will have to sort this problem out or it will cost a fair bit for manual parts although I could buy the instruments nacelle and ign lights for £85 from Turkey. The idea of going for the 2 Saxons was the one in boxes will sell when finished and then of course pay for the other, I hope!!
Anyway Vicar,thanks for your post, wish you well Alan.
