I was just wondering what the consensus is regarding Wedgetail Ignition ?
There is a nice video on youtube showing it being fitted and i was wondering if there is a real improvement in engine smoothness , starting and reliability ?
There are quite a few alternatives available from a single trigger / single CPU unit right upto the dual trigger / dual CPU , which is the one im looking at because it offers a switchable backup should anything fail , this sounds good but its quite an investment .
Any opinions or experiances please ?
 
Great System

Was a great price till Bins got the agency !!

Nearly doubled price now from when I got my two from Strawllia!

I was also looking at the Wedgetail system and emailed them with the question about if you need a dual CPU and dual Trigger, but there were also options of single, which components fail? They came back and said for the average person single trigger and single cpu would be fine. After all, if you have a failure and switch over, you are back to a single system and if out of warranty, you are no that better off. So for me, I think I would go for the basic system. But they never answered which components fail and how reliable is the system :-) Think as a first step I would upgrade my alternator before the ignition as I could do with a few more amps to run heated gear etc.
 
I had this on my hot 80 G/S, it was excellent, way better than the BMW electronic upgrade.

I also fitted one to a mates twin spark 100GSPD , it works really well.

I don't use any accesories so a upgraded alternator doesn't really bother me . Im hopfully going on a big trip next year so ill probibly fit a new rotor and maybe a heavy duty diode board. The backup system would be if the hall sensor failed or for some reason the CPU became knackered . But i could achieve the same by getting a bean can with a second hall sensor fitted and taking along with me a backup ignition module. So its really about improved performance
 
I have no experience of Wedgetail myself but this recently posted YouTube video is quite informative

 
I have the single trigger twin cpu version, as that was what was available at the time. Bike starts perfectly every time in all conditions, choke off right away, and runs smoothly. I had the sticky trigger unit a few times, so eventually decided to go digital. I've just set the static timing, and trust the programme to do the rest. Seems good.

I think its a phone CPU inside, which is an interesting reuse of tech. Low power consumption, very high reliability.

Fitting it was very simple. Just make sure the cable is safely routed.
 
I found the wedgetail easy enough to set up dynamic timing. That was very stable and made it easier to set up the carbs on a hot cam. But you’d be able to get a good setup on the old bean can I’d the components were good.
 
In 22 years no one ever managed to get mine as well tuned, and as reliably working, as I did by simply fitting the Wedgetail. And now i just don't have to worry about timing again. As they say in the instructions, just fit it, set static timing, and let the program do the rest.

On the Airhead facebook group, someone suggested after setup it was beneficial to also use a timing gun to fine tune. Is that not necessary?
 
Er, that’s where I would start, not finish!
Er, why would you start there if stripping everything and fitting the wedge tail ignition? Looking at the video, you set everything up and fire up. So the question was, do you need to fine tune with a timing gun, seems a reasonable thing to do rather than rely solely on static timing.
 
Ok for the hard of thinking:

I would build the bike, set tappet and end float (or better still upgrade the rocker bearings to shims), set the valve clearances, set the static timing, set float height, roughly set mixture screw, start it up, set the dynamic timing, ride it, fine set the carb mixture and balance.

I’d never just work off static timing otherwise you’d never know if the advance curve is working properly, would you?
 
If you are using the original bean can the advance should stop at 3500 revs so you can set up the timing accurately at 3500rpm, but on the digital electronic ignition the advancing can carry on beyond 3500rpm so I don’t know how you can set it up that way. I have the BMW digital tuna can on my airheads and set it up using the static timing marks as others have said. It seems to work ok
 
Seems good with just static timing. Best i've ever had it running. Just trust the program, that's the idea.
 
Might seem a bit strange considering its not been that simple for most of the very long history of airhead ignition systems. But it is just a completely different approach. New fangled computer thing.
