Why 3 x K&N?

Can you fit triple K&N's, remove the secondaries keep the cat and NOT do a retune ?

Risky.. Get a dyno tunenot only to be sure you ain't running lean, but the power gains WILL be significant.

You could. However, remember that Triumph tunes are on the lean side to start with. The bike will run much better with a custom dyno tune, even in stock form.

:iagree:

Ro6ert,
Why would you want to keep the cat box?
Chunk that POS as soon as you start on the TORS.
I have exactly what you're talking about doing.
cat bypass, TORS, Gi-Pro w/ATRE, secondaries removed, and 5 k&N filters.
Ran WAY lean till I hooked up the Dobeck EFI controller.
Also gonna remount my single exhaust,
so goody goody, I get to start all over again...

What can you expect?
quicker throttle response (without the secondaries, and with the Gi-Pro).
more OOMPH off the line.
Better sound,(w/ TORS)
increased HP,(without the cat).
Thats about all I can think of,
unless you want to include wheelies on command,(setting 1, 2, or, 3)
and spankin other bikes, (Just cause you can).

NO to K+Ns ?? do you know what your missing :whistle:

I just see no real reason to put them on, no noticable gain and since I am no mechanic I couldn't care less bout ease of access. Looks much slicker without them too

Actually there are gains in both HP & TQ & more importantly spread of TQ ( broader) Dyno tuned, adding K&N's will give around 8-10raw HP/TQ peak but you will be holding onto the peakTQ for much further up the rev range, where the standard setup is gasping.

Catbypass Tors & triple K&N definately need a new tune. Pm me an email & I can send you an excellent dynoed tune I had done for similar set up .( You need Tuneboy to install)
