Electronic ignitions

<< < (2/2)

Bryanj:
There is no easy way to increase the generator output but an electronic regulator will give a more reliable charge, Frank Cooper (Steve have you his web site address?) did have a circuit diagram for a home made one, at lower revs and give you the option of charging to a higher voltage, which would be OK with the car battery but NOT the original bike size one, whatever type you use the 3 ohm coils will tax the system and to be honest, unless you are doing lots of miles electronic can be a pain as if there is a problem there is never a roadside fix.
My honest opinion is electronic is only worth it if you are doing 9,000 or over a year as that would be 3 gap + timing checks

I'm with Bryan (most of the way)

My black 500 only does *9* miles a year (not 9000) so electronic ignition would be a bit of a waste.

"Silver Machine" is Frank's bike. I bought it off him last year when he was thinking of moving house and wanted a clearout. He is still busy and has made many "billet" parts for his Suzuki SV650 as well as hi own home-designed fairing. It's quality stuff too!

The bike is called "Silver "Machine" as it was featured in the Jan/Feb 1990 edition of that magazine.

Franks website is here, he details how he built the bike with no money!

Yep, I can when it's running properly cover 15 000 miles in a year going to work plus (If I trust the bike and have time off, a trip to Stafford etc.) Hence bike is showing about 80 000 miles, and on it's second speedo (last one self destructed but cb250 superderam one fits inside the original casing and is accurate)
It's a funny thing, Reason I prefer the 500/4 is it's simple mechanics and electrickery. Now I'm thinking of messing with them! thing is I'm resighning myself to the fact I'm not too clever at setting points. the 'original' set went on forever but when they died the death the replacements seem to just not want to co operate. Keep pitting or slipping out of adjustment. I've tried a strobe light but the timing wanders all over at tickover. Had a go at carb balancing but I don't have much of a clue when it comes to carbs so I decided to leave well alone. When the bike is finally back in commission I'll seriously consider looking for a competent mechanic to go over the set up issues. trouble is I'll be going some distance, the only bike shops round here are either moto crossers who don't, quite understandably want this kinda job or the main dealer round here who has some crinimally incopetent monkeys in his workshop! Try this one for a horror story:- I go in at the time knowing next to nothing about the tech side of bikes with a bare spoked wheel for a tyre to be fitted. Takes 2 weeks and when it's done (
