 Fezzler swung by today to show off his newly completed '78. Darn thing runs super fine considering it was locked up tight just a few months ago. Really nice running and riding bike.



 We rode up to the local Harley dealer. They were having "Hogs and Dogs"; an animal rescue benefit and hot dog cook out. We got to see some sweet pooches, checked out the show room, ate a hot dog and I saw more than a few "Pirates" checking out our vintage Japanese iron!

#1. The acceleration Scott's bike has is very impressive.

#2. His pipes sound even better than they look.  Like the kids say, they sound AWESOME! 
      A set of Rinehart Racing pipes would have nothing on those bad boys.  Perfection.

Only thing it would need in future is an even bigger displacement faster motor, few suspension improvements and a nice fresh set of sticky rubber.
Could be a fun one to hang onto...

 It's already got an R6 front end, iKon shocks and Avon rubber. I can't drag a knee, so that's plenty for me.

 The motor runs great. I've done a CB650 swap before, but it just lost something, to me. It was faster, yeah. And if I went that route again, I'd lose the exhaust (head pipes are too small for the 650 exhaust ports).
 Even with all the work, the VF500 Interceptor is faster. And my 500+ lb. Tiger would walk away from both of them without even breathing hard.
 I'm at the point where I don't feel like chasing ultimate performance out of 45 year old machinery. I enjoy them for the ride, the look, the experience and the joy of working on them. Any clapped out, $1500 Ninja on Craigslist would outperform them.

Yanking your chain Scott, on suspension as I could clearly see the overperforming R6 dual caliper setup.  One dual opposed early R6      design is enough...  I have a pair of quad piston fz6 calipers waiting .  They say anything worth doing is worth overdoing, right? ;)
I didn't realize that you have the Ikons, I had forgotten that.
Never had Avons, the BT45s I have been using are great, but apparently the Avons are a notch above.
Yes, it is quite true these bikes are easily eclipsed by so many modern or not so modern bikes.  Heck their may even be a modern MaxiScooter that can outperform them.  The Burgman is a pretty nice handling scooter but I prefer a tank between my legs when cornering.

Your motor is no slouch.

  It is good knowing and accepting the limitations of your bike. Trying to make it something it is not or not easily capable of achieving can be a huge investment in time and money and can lead to disappointment.  A nice restomod is my idea of a great bike.  I intend to ultimately go FunJimmy's iteration/route with the R6/FZ06 path of front-end.
A blend of the old with newer tech leviatates the bike to the next level.

I love the flow of your pipes, I am sure you are happy with the investment and enjoyment they give you everytime you twist the wrist.

You have built a very nice and unique bike.  Do get it appraised to have it insured appropriately with no fight from the insurance company.  Some start trying to be weasels when you have a claim.

Forgot to mention, the FZ06 calipers went to a quad piston design that bolts up to the R6 fork legs.  The FZ06 adopted the R6 forks after the R6 went to USD forks ...  so, you have that option if you wish to pursue that./adopted the R6 USD fork after several years with the R6 last iteration of forks.  The difference is the top triples are setup for handlebars...out of the box.
The adopted redesigned USD forks and same previous design twin piston caliper then went to the quad caliper which were  a direct bolt up on the USD forks or the original RSU R6/FZ06 forks.

If you are interested in even more insane stopping power and you have the twin piston caliper design you can use the quad piston design.

 Bike is running good. Still trying to rack up the miles so I can get it on the dyno. I don't expect it to make huge numbers; this will mostly be for tuning purposes.
 It doesn't pull quite as hard up top as I feel it should. But it runs clean, plugs look good and it runs CRAZY cool. Don't know if it's the tune, the vapor blasted head and cylinders, the coatings or what.
 The pipes are also loud. Maybe it just sounds like it's revving really hard. I just know that once it gets to around 7K it seems to slow down in revs. Maybe a faulty tach reading...I dunno. It'll get to 80 or 90 pretty easy, though!

The only thing I've really done to other than ride it is add some genuine Honda mirrors and a little HRC bling to the brake reservoir.
