KH250 electronic ignition

[TIM500]

Hi all, looking for an electronic ignition set up for my 250, looks like a couple available out there, anybody had any success with any of them??
Cheers
PS Hope you all had a great crimbo, and best wishes for a great tripling new year

Not the boyer
Feeling flush try the power dynamo system or go down the no nonsense route of sticking to points

Thanks Gary
You surprise me, always thought the boyer was good, been around long enough, will check out the other one you mentioned,

Scouse , you'll probably need to explain why you disapprove of the Boyer , as this is one of those "goldfish' threads , that keeps popping up !!

Earlier S1s and the S2s struggle to power the Boyer system , and still charge the battery , especially if you run with lights on,. The alternator output is too low. The KH250 has a greater alternator output , but it would still be touch. And go.

There may be another reason for Gaz's dislike of the Boyer system, but I am experiencing one of those Goldfish moments ?!!!

anyone any experience of the Newtronics system , on any Triple ???

( b.t.w. I always advise just sticking with points. As long as your points cam isn't worn , a set of new points and condensers is not only far cheaper , but equally or more reliable. sure to need to set them up and adjust them occasionally. But so what . it's easy to do . and easy to learn how to do. Let's face it , how many miles a year are you going to do ? I doubt you'd wear the points enough to need any adjustments for a couple of years in reality ? )

The boyer runs a wasted spark IE all 3 plugs fire at once, which means it needs a very good battery to run, also, if you get some fusty connections with the bike sitting, this could reduce the volts supplied to the boyer
It's caused quite a lot of hassle for a few people on here.

I ran a boyer for 25 + years on h1 and it was good as long as charging circuit was ok now changed to power dynamo which is still wasted spark system but uses less power

Ok. That all sounds like sense. My understanding is that the Boyer drags 1 .5v. Off the reading across the battery when motor is running .
On an S2 , the charging system isn't putting 13v out until engine revs above 4500 rpm. Hence flat batteries when running a Boyer , and either lights , or just creeping through town !! not sure what output is on a KH250 , but you get the idea.

( don't know what the Powerdynamo system. Uses. But , it's a complete all new generating system, so fewer old parts in total involved , and designed for the bike , so made to cope with lights and ignition etc. )

I'd still stick with points , on a KH250 , unless you just absolutely love the bike , and just want to give it an Xmas prezzie !!

And , I'm with Ray on this one. Especially on an early H1 . 69-71. With distributor systems , if it was my bike , I'd junk All those whirly bits and ht cables, especially the wobbly fast wearing distributor rotor and cap.

Phew, checked out the power dynamo system and much as I love my 250, no way is it getting a birthday present like that, especially as it rarely gets a run, and you have all convinced me to stick with the points etc, I even have a set of new ones in the garage.
Thanks for all the advice
HAPPY NEW YEAR

Second what the chaps say about sensitivity to voltage. Had a similar problem with the CB750 back in the day. Was fine provided the battery voltage was up to scratch. But when I ran all three headlamps (!!!!) used to start to misfire at high revs. No other trouble though.

Halfway through fitting the Powerdynamo to the H1A. Lovely looking bit of kit
