I've asked Mark if the postage is the same for 2 modules, will let you know when he replies, postage is bloody expensive from the states at the moment, $47 for mine alone. I am buying a blade fuse box as well though.

Nice one Ken, it’s bloody extortionate at the min isn’t it.

Cheers mate, if need be I can fire you some fish straight over if a favourable outcome buddy.

I’m in the sticks today with crap signal but I’ll keep my eye on the phone in case you need to sort it and I can act swiftly for you.


Catch you a bit later on mate and thanks

Hondaman ignition and blade fuses….I’m in too if it helps. Strangely he has $18 dollars stated for uk postage?

I'd also be interested in the ignition, if it's not too late to jump on..

 ;D was wondering about that, and when we went to a fish barter system.  Thoughts of you coming home from a hard day's trawlering with a box of fish for Ken  ;D

Would value be based on size, weight or rarity?  For example blow fish is probably worth more £per kg than say a Chub, cod or trout. Is sea fish worth more than fresh water fish and does salmon vary in worth if is caught at sea or fresh water.  ::). Just wondering.

On the topic of Hondaman ignition, do the original capacitors need to be in full working order?

I read, a while ago, his thread on development of the system which is really interesting.  It will run with no condenser facility as far as I recall.

In combination with many supplement type systems, the load experienced by conventional points type original arrangement by them switching the coil negative in and out is fully taken by a switching transistor in the new part of the electronics.  The points then just act as timing pulse (to effectively fire the starting pistol in the module) and so have very minimal load requirements which is why the condensor had to be there and prevent the full load causing a spark to jump the points gap.

Just a late chime in i can remember the Boyer ignition units when brand new idea, they were developed for the Nortons and Triumphs(especialy the triples) due the quality of St Joseph Lucases points. Never new of a failure back then, the alternative was lumenition which didnt work if the points cover was left off(sunlight on the sensors)

Without a capacitor you'd have an even steeper rise time, which is good, but you'd also have an increased risk of an erratic 'multi-firing' so to speak, which is not so good. So if Hondaman left out the capacitor in his module, I'd advise you to keep the stock one wired. In my module capacitors (the blue parts in the pic) are incorporated, so you can disconnect the old ones.
