My used `81 CX100 w/6K miles on it came w/Dyna 3 ignition and stock coils. In 94+ miles more it has never needed coils replaced. Have heard a lot of complaints here over the years of Dyna coils.
I would take the time to accurately mark the timing marks in relation to true top dead center. I have never seen a Guzzi that was not off on the marks. Some better, some worse so if I'm useing the marks to set ignition events, I make my own marks. It used to be common that I would see a pointer shaped piece of aluminum bolted to the inside of bel housing . That would be for a time when the thing was apart. If I'm just setting the ignition , I use a sharpie to write on the flywheel . Don't use too large of a degree wheel or you have to pull the head pipes to bolt it on . I'd like to see a video
The install went well. I'll begin splicing the video soon. I ordered the auto tensioner from MG so it should be here this weekend. I am having a little bit of jumping around in the timing but it has been about 8 mo since I tensioned it. I have 5 ohm coils already and they seem to be firing well. Once I get the timing close I'll start dialing in the carbs as well. I know they are running a little rich. Hopefully bringing all this together will be a smooth running engine. If not I'll send Dyna their product back and ride with points forever!
^ That kind of advice is priceless. And exactly why i joined this forum. Question, is it necessary to change the gears or would changing the chain suffice?
The Valtek? cam chain tensioner (spring) improves the original manually adjustable chain tensioner. Never had an issue with my Valtek chain tensioners but I'm not a perfectionist either. My '87 LM IV ran just fine as did my `81 CX100. Hardly ever had to adjust their carbs or idle.There are different timing gear sets available and have heard some are better than others.
