Postby Blackngold » Sat Jan 16, 2016 10:43 am



I've searched site and found little on this subject. So i'll start w/dumb question 1st.Do we have them? Where are they? How many? Do they suffer from age,vibration,heat, deterioration? Are there upgrades? THX in advance for all info on subject!

yes they have them. there are 3. are in front of carbs under coolant tank. can go bad but not that often. you could adapt a hotter coil on it but the stock does a good job if the rest of the system is good . a coil will only build up until it can fire the plug gap so even if you have a 60000 volt coil it may never put out half that. also the coils ground in the brain the hotter coils may tend to shorten the life of it.

So having 3 means each coil fires 2 plugs/cyl. right? And the brain box tells the coil when to fire? Can new coils and brain still be found at parts houses or from Honda for 1500's? Have been told by Honda mech. some parts are getting scarce? Why do some people upgrade regular coils to higher output/racing coils --those pretty yellow ones? I just don't want to continue to put money in a bike or break down only to find I have to import a rare part from Europe for half the cost of a new bike. THX for the education!

new coils are easy to find the brain you can get used . the 1500 is not a high rpm motor and not a hotrod (they will hold there own ) when you start to bring up compression higher rpm playing with fuel you might need more coil voltage. most bikes with the hot aftermarket coils don't need them. Harleys use them a lot because a lot of people do eng work (pistons cams ign. ) I know a bunch like that but they still don't try my 1500.

You find little written about 1500 coils because they are more than adequate and pretty much bullet proof.

What specific problems does your engine have?
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

The Honda dealer is the LAST place I would go for parts for your bike... OEM Coils are available here for far less than you will pay at Honda: http://www.partzilla.com/parts/search/H ... parts.html as are many other OEM parts for your bike.
What exactly is your bike doing that has you questioning your ignition system?

THX dennislp for info! Just a few more Q's. What about plug wires,should they be replaced as they are 17 yrs. old and for that matter how about radiator hoses, vacume hoses. With only 75,000 miles should I replace timing belts or wait for 100,000 mile interval? My bike runs fine as of now--like to keep it that way by heading off any problems b4 they occur.

I've been left on side of road twice since owning bike, once from "tip over safety device" and from alternator dying. Was able to diagnose and repair both times with info on this site (THX WING ADM!) Have since added roadside asst./towing from bike ins. still ruins a perfect day. Took a fun trip out west last April and want to do it again this spring so just want to get ahead of potential problems.

if there isn't a running problem I wouldn't worry about wires . get a spray bottle lightly spray the wires if there are any bad spots it will miss if none good to go. when people bring me a 1500 or any 1000 1100 or1200 if they don't know history I always change belts to be sure if one breaks the eng will cost more to fix then its worth and they can look good and be about ready to go . there are real good directions on here on how to change them .

rad hoses on 1500s last a long time vacume hoses die quick where they hook to intakes one other hose that is a problem is under carbs between intakes but you need to remove carbs to do it .

If you don't know when the timing belts were last changed, I suggest changing them. You can get the belts from NAPA for about $30 each and it is not a difficult job to change them if you have a good place to work. A helper is a plus...... The procedure is layed out nicely on this site. A little time and patience is better than replacing an engine due to failed timing belts.

I doubt the timing belts have ever been changed. I've owned bike for last 25,000 miles. guess this is my next project. Looked thru step by step instructions, seems do able. THX for all replies!

There was a post a few years ago on Saunders goldwing forum regarding a coil upgrade to a C3I coil pack from a dodge neon to an 1100. I actually made this upgrade on my 1100 and it really worked well. I think the new coil and harness where less than 80$ at Napa . I used 8mm plug wires and mounted the coil pack to the air filter lid. It started a lot easier and improved the mileage some. I made the modification mainly because the oem coils where ridiculously expensive. I see no reason why you couldn't purchase a coil pack from a 6 cyl. GM or Chrysler car and make it work. You would need to buy the plug harness as well along with some plug wires. Maybe it's already been done? Something to think about when you consider each coil is around 100$ each times 3.
