Unitrak Engine Ignition Options

[Julian_Boolean]

What ignition options are there for the Unitrak engine, I think my igniter unit may not be advancing the ignition, also my wiring is in pretty bad condition, so I'm thinking about replacing the whole lot and wondering what the options are.
Ones I know of so far

Dyna S - needs J casing and advancer
Dyna 2000 - needs J casing
Boyer Bransden - no idea if this fits the Uni engine
Kawasaki igniter - expensive new and unknown quantity buying 2ndhand, especially as my igniter looks like an 1100R one rather than a Unitrak one.

Any advice gratefully recieved

Your best option is dyna 2000 or dyna s and get a j inner casing, both great ignitions

unitrak cdi should have this part no on the sticker 21119-1071

I think I'll probably go Dyna S with the J Casing and Advancer.
I don't really want to be relying on 33 year old electronics, wiring and coils
I could get the Dyna 2000 and not use the J mechanical advancer, but I don't think that it's worth the extra £150 to do away with the mechanical advancer, and I quite like the simplicity of the mechanical advancer and the ease of seeing whether it's working or not.

This new fangled ignition stuff is all foreign to me.

I went for the 2000 system and am happy.
Easy to set rev limiter and next year I'll have a play with its programming to see if we can make it any smoother.
The tacho output was dead handy too.

I'm torn between the S and the 2000, 2000 has nice features and easier to fit, S is £150 cheaper, if I can get some overtime over Xmas and New Year that will probably pay for the 2000 and coils.

I have Dyna 2000 on my GPz Unitrak engined Moto Martin. As you correctly point out you will need J casing to mount. Also make sure the Dyna box is isolated from vibration. I think from memory Dyna S is not listed for Unitrak but cant remember why.

I ran Boyer on my GPz track bike. It was built for Team Glam and included rev limiter. Only issue ever was with connections at a very wet Angelsey track day but electrical grease and tie wraps solved that. They are also UK based so if it does go wrong they are at the end of the phone and are very helpful.

Unitrak motor in my ELR is connected to stock ELR igniter with no issues.

Does the Boyer go straight onto a Unitrak casing, or do you need the J casing, I sent Boyer and email asking this but haven't had a reply yet.

To be honest I cant remember and i sold the bike a few months ago so cant go look! I think it was Unitrak given it was made for the bike.

I found this post from a thread with the title "GPZ1100 Unitrak Ignition Otions"

I have Dyna 2000 fitted to my Moto Martin which has Unitrak motor. It is correct that you will need to replace the casing but they are fairly easy to come across. My other GPz has Boyer ignition which is in the Unitrak case. Neither require the mechanical advance/retard.

I think I have the standard ignitor somewhere as well if you prefer to stay standard.

It was fitted in a J case
