There is ZERO tolerance on personal attacks and ANY HYPERLINKS to PRODUCT(S) or other competing website(s), including personal pages, social media or other Forums. This ALSO INCLUDES ECU DIAGnostic software, questions and mapping. We work very hard to offer commercially supported products and to keep info relevant here. First offense is a note, second is a warning, third time will get you banned from the site. We don't have the time to chase repeat (and ignorant) offenders. This is NOT a social media platform; It's an ad-free, privately funded website, in small help with user donations.

Like the new V100, GuzziTech is full throttle into the future! We're now running on an all-new server and we've updated our Forum software. The visual differences are obvious, but hopefully you'll notice the super-fast speed. If you notice any glitches or have any issues, please post on the Site Support section at the bottom.

I've seen a modified shift lever which does not involve any frame welding but I don’t recall where?.
The attached photos show and adaptation to change the shift pattern. This was accomplished by adding a shift lever, linkage and welding a thick adapter plate to the frame.
Also the photos show...
Some photos
I added some photos to my yahoo site, however I can't seem to make photos available for public viewing.

So if not try Photobucket

The fairing was from JC Whitney which I purchased in the mid-70s. When I was remounting the fairing, after the restoration, I found that it was best to make my own brackets from aluminum flat stock. Also the clear plastic windshield was so brittle with age that it cracked so I reinforced it with...
I would guess that on a points system, a five ohm coil would reduce the current through the points as compared to a 3 ohm coil and consequently extend the life of the points (as well as the coil). On an electronic pointless system the power handling capacity of the switching transistor would...
Since were on the topic of coils and ignitions I thought I'd show a short clip of the Chrysler pointless ignition adapted to the Guzzi.
Pickup coils are exactly 135 distributor degrees apart. In this example a Y connector is used sending the pickup coil signal from each of the pickup coils to...
If I understand your question any reduction in voltage to the coil results in a concurrent reduction in spark at the plug. This is correct. Also at low rpm, current draw is greater than that at high rpm. Higher current draw means more amps going into the primary circuit producing a stronger...
Only through a bypass mechanism or circuit would the ballast resistor provide a boost, the resistor simply reduces voltage. Some also think that a condenser used in a typical points system provides a boost. This is debatable. While primarily used to attenuate sparking on the points and increase...
The attached video shows a test of a pointless ignition system using a universal coil from accel.
The system is Chrysler pointless ignition. Specifically the video shows current draw or amps as the ignition coil is used.
The trigger pickup is mounted with an electric motor assembly. It can be...
Re: UPDATE: 74 850T Running Issue
I'd like to help but since I run Chrysler pointless ignition I couldn't comment on the Dyna system. It looks to me like it's a Hall effect with separate left and right systems in one control box. The coils you use with the system should not exceed the maximum...
Re: UPDATE: 74 850T Running Issue
Just fyi
Most of your modern-day ignitions are CD (capacitive discharge). This means that the primary voltage (12 V) is transformed to around 300 V and momentarily stored in a capacitor until discharged into the coil. This produces a sufficient spark and has...
Re: UPDATE: 74 850T Running Issue
The primary field collapses in reverse order and likewise the induced current is generated in reverse order, but how this affects electrode erosion is a mystery to me.
Re: UPDATE: 74 850T Running Issue
If the plugs are fouling causing the engine to stall than that condition can either be a cause or a result. I don't know if you've performed a compression test? But if your rings are bad there could be a situation in which too much oil is getting into the...
I replaced my shoes with new material. A local shop did the fitting at a cost of about $ 15 per shoe. It was a tight fit but no need to sand or scrape material. The new shoes are actually on a par if not better than disks. It does take some careful adjustments to get all 4 in the front working...
I have the 40s on a V7. They were part of a performance package. Once adjusted they run fine, very smooth throughout the rpm range. As an experiment I put back the 30s and the bike ran like crap. No power until after 4,000 – 5,000 rpm. So I quickly went back to the 40s, but the tickle is messy...
If you’re electronically challenged I’d stick with available commercial systems. However if you are adventurous and looking for a reliable, inexpensive alternative, using the stock ignition distributor and advance curve you might find the Chrysler pointless ignition adaptation interesting...
