I have a 1999 Sportster. I had the original ignition module that went out. Will this work? or will I still need to buy the external parts that go under the seat as well or does this had those parts integrated like the original part?
Brandon N on Oct 7, 2018
BEST ANSWER: This part will fit
I get my ignition module in and go to put it on and the instructions say I need a mechanical advance assembly! When I ordered it the operator didn't say anything about it and all I read was fits your bike! Will it not work if I put it on and not have the mechanical advance assembly?
Shawn R on Mar 3, 2017
BEST ANSWER: no
Why don't the bolt holes line up for this ignition module when in the 7 o'clock position?
A shopper on Dec 15, 2016
BEST ANSWER: I remember mine didnt fit exactly like the diagram, but it worked I had to keep the adjustment pinned all the way in one direction however.
What other parts do I need ?
A shopper on Aug 18, 2016
BEST ANSWER: The ignition module is complete, you may want to order a new coil and spark plugs but they are not necessary. The installation was simple, just have the direction and the wiring diagram for your bike and went well.
The ignition module only has 2 wires and my factory wiring has 5. What do I do with the 3 extra wires?
Rick N on Dec 29, 2017
BEST ANSWER: I ended up getting the integrated ignition module from a dealership.lts plug and play from there.
Do I need a mechanical advance unit for a 2001 sportster xl 1200 custom? Does my bike have one already ? Or can I just replace module and I'm good to go.
Broc C on Sep 15, 2017
BEST ANSWER: It requires a mechanical advance. I do not know the application for a 2001, to new.
So where can I get the mechanical advance unit for this module?
Chris on Aug 4, 2017
BEST ANSWER: Many after market manufacturers offer this, just do a search for mechanical advance unit for what ever bike you have. Hope this helps. The Compi-fire really worked great on our 1982 sporty. Jim.
I have a 80 ci evolution engine on my chopper and not sure exactly what year, maybe between '90 to 2000. What ignition module do I need to get?
Djtor on Sep 17, 2016
BEST ANSWER: Sounds like you have a 1345 cc engine. Sounds like it may have been modified over the years.
Is it setup as a single fire or dual fire ignition? If you don't know the difference I really suggest that you bring it in to a good shop.
I have a 1998 sportster 1200 and I need to replace the ignition module. Problem is, it says it needs a blue rotor, but this bike does not have a rotor. Will it still work ?
shoesvw on Oct 6, 2018
BEST ANSWER: Yes this ignition will fit the rotor will replace the old bell/cap rotor be sure to align rotor to the shaft ..

Matthew L on Aug 20, 2017
BEST ANSWER: Yes, but requires the use of a mechanical advance unit

Excellent bang for the buck
I recently purchased this ignition for my 1988 Heritage Softail. The price was great and the delivery was awesome too. It took me about 20 minutes to install and it fits great. Timing the bike was so easy and the instructions were very clear on how to install. I would definitely recommend this to any one changing from a points ignition or from your stock electronic ignition. BEST BANG FOR THE BUCK
