Faulty ignition module upgrade or mods?

Hi all, ive been lurking in the distance for a while since i got this bike a couple years ago and now I cant seem to find my answer so I figured id register and ask.

Ive got a 2001 vulcan vn750, mods done include vance and heins pipes, and an ear shave kit, extended forwaed controls and thats about it. The bike currently has just over 10,000 miles, I put about 2800 since I got it, the bike was my uncles and was given to me. He had a lot of carb issues so he got a Harley, when he had carb issues the bike was constantly on a charger so i think that may of had something to do with this problem. Ive only had the bike for about 2 years.

End of last season I tried to get out a few more times and I kept having issues with intermittently losing spark on my front cylinder. I read through a few threads and tested my ignition coils and pickups, I even swapped my coils and the problem stayed on the front cylinder so its not coils and both pickups tested good, Ive narrowed it down to the ignition module itself and with the bike being 19 years old They dont make that part anymore.

Not wanting to take the risk of having a faulty used part I was thinking, if I am reading right, the coil pickups trigger the module when to fire which cylinder, the gm vortec engines and other engines do the same thing, could I possibly remove my faulty ignition module and retro fit a gm or other series ignition module to my bike? I know its kinda frenkinstining, but I just dont know what to do. I am very mechanically inclined as well as electrically, if anyone has any other ideas or solutions, or even know where i can purchase a new module i would appreciate the input.

Maybe check out Partzilla.com, you can search by your model year under the “ignition system” category if this link doesn’t work.

Two recent posts, this first one had a bad wire from the CDI to the front coil, the wire had actually been fixed by a previous owner, and re-done by the poster of this thread when the spark died again. Maybe find that wire and test it?


Second thread has a link to a replacement CDI that's plug and play, and also cheaper than OEM replacements: https://www.vn750.com/forum/22-carbs...ml#post1283267

Link to the ignition, you might message Jason and see how it worked out, but also read the thread to make sure I pulled the correct link: (doc file) http://www.ignitech.cz/zdroj/en/vyro...50%20TCIP4.doc

Link I found using the model number for the unit: https://www.ignitech.cz/old/english/tcip/tcip.htm
