Points versus Boyer

[Seamus]

Hi All, I guess this has been around a few times, so apologies to those who are fed up with it.
I am trying to get the dwell angle and strobe timing to work on my K1. New points plate etc fitted.
Is it worth junking this and going straight to a Boyer. (Where do most fit the box?) On the US forum, there is a large article relating to the Dyna system as to where it causes sparks to reduce as rpm increase, so I ahve dismissed the Dyna.
Thoughts comments gratefully received
Cheers

I wouldn't dismiss the Dyna (don't forget that there are two versions, the "S" and the "2000"). Z1 Enterprises have the Dyna S at $120 which replaces the points plate (no other boxes)

I use the "S" on my replica racer and with good succes, good spark allround, very good starting. Enjoying it.
Have a Boyer for my Turbo projekt but think I eventually will go for a "2000"

[Seamus]

Thanks for the replies. I understand that the Dyna S replaces the points, but is'nt there a recommendation that you also replace the coils to ensure sgood high speed running? or do the standard coils work OK. I have a 70 K1 (US import).
Does the 2000 system have a black box (a bit like the Boyer)
Again, I am open to advice from folk who have been down this road before.

To be honest, unless you want to race or do high mileages i dont see the point(sic) in shelling out good money on electronics when the contact sets are as reliable as they are---yes they do need maintainence but they also rarely go totaly tits up and strand you in the middle of nowhere and yes i agree getting the gap and timing spot on can be a nause if you dont do the job regularly and have a good "feel" for using gauges but then practice makes perfect and you have to have a strobe to set the electronics which you dont need for the standard set up.

I'm guessing lots of folks will shout me down on this but i do low miles and live with the contact set up!

My 550 runs and starts fine with the contacts.

Starts on the button or the kick every time and revs cleanly all the way to the red.

I check them every thousand miles or so and with the miles I do that can be quite a long time between checks.

Personally I'd go with Bryan and stick with the points.

But to answer your questions:

1. The Dyna S replaces the points and has no black box
2. The Dyna 2000 does have a black box and allows you to programme custom advance curves etc
3. Dyna make a range of low impedence coils (eg 3 ohm vs std 5 ohm) but these will draw more power from your charging circuit so you had better be sure that it's up to it! Search on www.sohc4.net/forums for "Dyna coil" or similar as there is  loads of info on this over there.

Thanks again for the replies.
Looks like the favorite is to stick with the points. I just wanted to know if the replacement by an electronics system was the usual route for these bikes. I don't really mind setting up a points system as I have the tools and pleanty of patience

Cheers

PS I will be asking more questions soon
