Virtually eliminate missed shifts.

Help eliminate false neutrals in the upper gears.

Find neutral easier.

Help prevent shift fork and gear dog damage caused by missed shifts.

Funny thing about this kit...... once you install it, it fixes the shift action and, due to human nature, the rider forgets it's ever there....... (until you ride another bike)

The kit requires 1-2 hours to install. Installation involves removing and replacing the clutch basket to install the new shift parts.
As of 04/12, use a factory Triumph Service manual section regarding clutch basket R&R - there are no Factory Pro installation instructions (need a bike to document install)

Have a "properly tuned" 955i? Still won't take full throttle at low rpm? Still sounds like it's gargling with socks in the airbox? Esp. in  2nd gear, "in-town" operation?

We richened and leaned the fuel , advanced and retarded the ignition timing and never totally fixed the low rpm "business" on the, otherwise stellar, (I think that the Cannondale / Sagem fiasco hurt Sagem in the mc industry........)

This mod allowed us to finally make the bike run smoothly at cruise rpm / small throttle opening.

Incidentally, the Sagem fuel injection worked fine - IF properly tuned. Tuning the FI with Tuneboy or TuneECU 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 955 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 that it annoys -

These will have to be purchased direct from Factory Pro / 415 883-5620
9-5 pac time, M-F.

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 MY 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 running, you'll have to do the rubber mod or the person doing the installation will have to do the stack and rubber mods. 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.

Needless to say....... there are no guarantees, no warranties, no implied warranties, no unimplied warranties, no warranties of fitness for any purpose, no fitment warranties or any responsibility for what you do in your spare time, your wife, your kids, the dog, your neighbors, your boss, your in-laws, your truck, etc. All taxes and duties are the responsibility of the user and so on.......... I'm not forcing you to buy this stuff that doesn't fit a triumph... yadda... yadda.... yadda...... (and yes, Marc Salvisberg wrote this....)

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...........

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?

Thanks   -    Kent

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


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.

Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting book with great starting ideas.
