New Moto Guzzi Door Mats Available Now
Make sure the customer understands the importance of keeping a good battery up to the Dyna. They are reliable but if the battery voltage is allowed to drop they can get spiked when the motor starts. Usually its the left hand side circuit that goes from memory?Personally I nowadays prefer points. The twin point system is very easy and stone axe reliable as long as the points heel is greased from time to time.OOMVPete
That's interesting Pete, what happens when they spike ?I've got an LM 3 here with Dyna has intermittent 1 cylinder drop out for owner, will not do it for me, not certain if I've fixed it or problem waiting for owner.He is a FIFO rock doctor--bike gets left for months, flat battery certainly an issue with him. Possible it only does it with low battery, heals when charged / replaced ?Twin points the most reliable ignition for sure, you can set them up perfectly and they last indefinitely, what's not to like ?They even provided a felt wick to oil, 2 squirts from an oil can once a year, hardly a major chore.
Does the 850 T3 electronic setup work for the 73' V7 Sport 750 motor / dustributor as well?ThanksJim
I've installed Dyna systems on my personal bikes as well as customer bikes over the years. On Tonti-frame Guzzis, the Dyna system works famously and I found it to be a great upgrade over the dual point setups.There will be people who will argue for points on EVERYTHING; note I've distinguished the Tonti frame Guzzis here. Points are fine on an Eldo where you can get to them without taking the gas tank off, AND they are single points. On Tonti-era bikes, Guzzi buried the points down in the V Valley, plus the dual point setup ofter required tedious filing of the points plates to get the timing just right on both sides.Guzziology has an excellent writeup on this topic if you want another opinion, but I've been down this road enough to feel pretty confident this is the way to go.
adding jumper cables to a bike with the ignition on can spike it as well. after my dyna failed while I was on vacation, I am a points man again. this is after running dyna for 30 years and staunchly defending them against all negative press... if you run them, carry a set of points.
Actually the twin cb housing is in exactly the same position as the distributor was, it's the chassis that's different.the advantage of twin points is in getting both sides perfect, requires a little skill but only like being able to time two singles. I just alter gaps, no filing.
Single point distributor, (And cam gear obviously.) are different between the two points systems but I'm wholly in agreement about the points plate filing. I've never found it necessary, just set it up by gap. As long as there is sufficient dwell for the coil to make a fat enough spark to light the fire all the way to red-line who gives a shit if the gaps are the same? Nice thing is that as the points heel wears, and they do eventually, all you do is open them up again until the timing is correct and you can go again.In my experience as long as you throw a new pair of condensors at the system every now and again the points faces will last pretty much forever. Eventually the heels wear down but it takes a very long time if they are lubed.Pete
You can fit a single point dizzy to a Tonti or a twin point to a loop by swapping the shaft gear. Any cam with a Tacho drive won't fit in a loop I don't think? Charlie will correct me I'm sure if I'm wrong?Pete
One thing electronic ignition can do that points can't is idle stabilization.To bad it doesn't appear dyna or the other electronic units available for Guzzi's use idle stabilization.
while you can run a single point dizzy in a "tonti" motor, I wonder if the single point dizzy (cap actually) wouldn't hit the tank if fitted in a tonti frame...
Joe, I called you tonight & left a message at your shop. We have a new Moto Guzzi ignition kit that uses dual light beams to track crank/cam position and trigger coil saturation and spark trigger. It's the only full rpm multi spark ignition that i know of in the world. You might be done with your customers restoration but wanted to see if we could help offer a new option besides the mediocre hall effect ignitions we've all been stuck with until now. We have Ace Mallott testing one right now to help us fine tune ignition curves if necessary. The mounting adapters are in stock and we will be shipping the first ones very soon!www.c5ignitions.com if you want to read more about the technology. We do not have them for sale on our website yet but contact us if you have further technical questions. Paul
I was doing some searching a year or so ago. I found this company http://www.powerarc.com/ids/development.htm They don't list a Guzzi ignition kit on their site currently. If I remember correctly, the Guzzi dual point replacement had been developed and some units had been installed in customer bikes. I inquired by email. To my surprise I got a phone call from someone there who was very helpful & knowledgeable about the product line. It may have been the owner or lead engineer. I was impressed overall. No experience with the product yet..There are these guys who offer an alternative for Guzzi point igniions http://www.cajinnovations.com/MyECU/index.htm Don't know much about them.This German Company http://www.silent-hektik.com/MG_Bosch.htm looks to have some high quality offering, although they all seem to be drive by pulse wheels mounted to the crankshaft. I don't speak German, so it's hard for me to tell muchNo affiliation with any of these co,panies. Just sharing what I found.Matt
