Supertrapps on VFR700

I've picked up a rough but low miles '86 vfr700. It has Supertrapps on it. While I'm cleaning the carbs (it idles on choke but won't take throttle) I'd like to see if it has been jetted or not.

If 118 is stock main, what would be right for Supertrapps?

And...were these Supertrapps available as a complete exhaust, or do I still have the stock headers and these are just the cans?

Many thanks...

I had a 87 VFR700 years ago with Supertrapps. They are just slip on mufflers bolted to the stock headers.

I ran mine with stock jetting for 20k+ miles. If I remember right you could run stock jetting with 6-8 discs in each muffler.

The sound that came out of those things was fantastic...

If 6 is the magic # for that bike...Great..... But it's easy to try different settings, and you well feel the change..... I liked the ST I had on one bike.... With the exception of it blowing exhaust crap all over the bike.... since it comes out the side.... But it wasn't the cleanest running bike......

Now that the bike is home, I can see these supertrapps are slip-ons, which is fine with me. The stock headers don't look too bad but there's considerable rust underneath. It wintered in MD for years before being brought here.

Opened the carbs yesterday, the stock mains are still in there. I don't think these carbs have ever been touched, really. The idle screw caps are still in place.

Thanks, I'm looking forward to hearing it under load...the Supertrapps on my Vmax also sound really, really good....

wow coffeebrake how many bikes do you own ??? are you still working on that kz400??

I used to a connie to, so thats how I recognize you

I had a kerker pipe on my old 83 saber ( same company now ) man I loved that sound, thats why I went with a vfr
I missed that V-4 sound and it's a good all around bike
I can't put as much junk as I could the connie but I like the way it handles and rides

Still got the Connie, I painted it myself this summer so now it's a pretty aqua blue.
Still got the KZ440 but it's still not on the road, converting to single carb as time allows.
Also still have the Nighthawk for the commute.
This VFR will likely replace the Vmax. As much as I love the powerplant, I really need a better-handling bike. When it comes to cuves, the Vmax is about as agreeable as a bear with a toothache.

I remember your screen name....I shoulda got a Sabre but the deal on this VFR was just too sweet...and I like it more and more everytime I see it. I can do the paint, bodywork, and carb/brakes/suspension work it needs, so it was a suitable project and likely a keeper.

Hello again!
