| Billet Velocity Stacks (patented) | |

 Factory Pro stacks installed in airbox |
We richened and leaned the fuel , advanced and retarded the ignition
timing and never totally fixed the low rpm "business" on the, otherwise stellar,
SAGEM FI equipped Triumphs.
(I think that the Cannondale / Sagem fiasco hurt Sagem in the mc industry........if
only Canondale had had us do the tuning)
This mod allowed us to finally make the bike run smoothly at cruise rpm / small throttle opening and pick up a couple hp in the low, mid and upper midrange.
Incidentally, the Sagem fuel injection worked fine - IF properly
tuned. Tuning the FI with Tuneboy is the only way to get things "BEST. A power commander
will make it better, but not as well as properly tuned with Tuneboy.
And if it's a power commander custom "tuned to an af ratio....... and not to "best
power", you're missing a lot........
The dealer's Triumph tunes were maybe OK for the bike that they were made on, but, as we all know (or will know), each bike is an individual and one can't expect a "blanket" tune to make all bikes run perfectly (even with the same accessories installed). It's probable that manufacturers have to do emissions testing on each "tune" to allow the dealer to change the "tune", but it's only by chance that a bike will be perfect with a dealer downloaded "tune" (but it does give online owners groups a lot to talk about).....
Anyhow, this is how I installed some of our Superflare stacks on a 1050 and was able to use Tuneboy to make it run nice at low rpm and stop that annoying "gargling" at cruise in town.
I don't expect that everybody will be annoyed by the "gargling" and full throttle / low rpm bogginess - it's something that annoys the heck out of us -

The
#3 rubber will have to be hand trimmed to clear the inside of the airbox, also.
Since I was at the tuning building, and not the machine shop, you'll see that I
hit the belt sander on the prototype (not yours!).......... The 2.235" / 56.8mm stack width is a good number and
if you are off a mm or so, it's fine.
If I could figure out a way to mod the rubber nicely, I'd sell a set of pre-made
stacks. I can't figure out how do it to cost effectively, so if you want to fix
the low speed running, you'll have to do the rubber mod or the person doing the installation will have to do the rubber mod. On the rubber mod, it's just the part that in on the inside of
the airbox. Test fit the rubber and you'll see.
Have fun!

These are the Sprint stock stacks. Ours are a bit shorter. |

 The stock rubber Daytona stacks are a bit shorter than our billet 60mm stacks. I think that the stock Sprint rubber stacks are a bit too long and the shorter stock Daytona rubber stacks are a bit too short........... and not designed to produce best torque or power. |

Hey Marc, I got the velocity stacks in the mail Thursday and put them on today. One thing I noticed; the factory stacks on my Daytona are already significantly shorter than the ones that were pictured from the Sprint on the website? In fact, they were even shorter than the ones I just installed from you. Haven't had time to go for a real ride to see what changed on the bike, but I'm going to assume that I'll loose some top-end while gaining a bunch of mid-range. Thoughts? --Steve Bassen

Ride the bike......

The extension of
the laboratory for engines of
the Swiss Federal Institute of
Technology was completed in
about 1935. Its architect was
Rudolf Otto Salvisberg
(1882-1940). He had a successful
career in Berlin but returned to
Switzerland after the advent of
the Nazis. His architectural
style was somewhat similar to
that of Erich Mendelsohn. The
staircase of the laboratory is
in normal use but well
preserved. Edited to the tunes of Chemical Residue by Herbie Hancock. |
