My 1984 1200 didn't have any kind of rev limiter. It would wind right up to and past red-line. You didn't get into the power band until about 4k.

Well I went for a ride today and.....................................I am convinced that the 1500 coils don't allow the 1200 to rev out. Even in the lower gears 6,000 to 6,500 and it will not rev higher.

When all else fails.......... use a hammer!

I think you may have hit on your problem, and 135,000 is not high mileage for a Honda.

Original Coil-Paks -

Hey Eric - Have you tried reinstalling your original 1200 Coil-Paks to see if the limit in RPM is still there ?

Good Luck Michael -

Sewing Machine Test -

Hey Eric - Have you been able to sort out the RPM limit problem with your 1200 ?

Normally I don't rev Ol' Beuford T Dudley above the 6k RPM mark, but decided to go ahead and run the "Sewing Machine Test" on my last ride this week. I don't think "The Dud" liked it much as the vibration gradually increased up to the RED LINE, but there was no RPM limit found and (thankfully) not one of the pistons changed holes.

Good Luck, Michael

I am sorry that I haven't been on here for awhile, so for the first question.

I went with the 1500 coils because I couldn't get the 1200 coils and the 1200 was off the road because of this. There was a thought that the 1500 coils were a up grade to the 1200 coils and it seem like a good idea to put better coils in and not have to toych them again.

For the second question. There is some Aussie Hoon that like to give the sports bike a bit of a run for their money. And I had that 1200 running as good as a standard 1200 could run, and it was a lot of fun to ride. Ask the Fossil................he chased the 1200 up through the Adelaide hills. And the real power for the 1200 is in the 6-7,000 rpms. So it is not very often that I wanted to be in the upper rpms.

The roll for the 1200 is changing and the 1500 is taking over the long distance touring. The 1200 is now going to do the solo riding and general run about duties. I will stick with the 1500 coils understanding that it will not run as hard as it could but will still make a great solo tourer. Everything else about the 1200 is as it should be. The MPG's has not changed from when I first brought it, it starts and runs smoothly and it is a joy to ride. I think that as long as I can get parts for it, it will do the secondary job very well.

Thanks for chasing me up with this, you are a good spannerman and help us older Goldwing owner to keep them running. We are lucky to have you on GWOF.

On the older bikes which are carbureted a lot of things can aid in poor high speed performance. Partially blocked main jet rust in the shutoff valve. I think the 1200 had a vacuum shut off that was prone to failure. Poorly seating float needles can add to the issue and usually you will see gas dripping out of the overflow lines. Plugged air filters due to mice or men . Also ignition timing is set with a degree wheel so if that moved the engine may idle fine but top out early. I doubt fuel quality would be an issue.

Also for the record all GL1800's in all years do have rev limiters, First gen Valkyries do not.
