Question To De-Snorkel or Not to De-Snorkel?

I recently installed a Tec Bike Parts de-cat x-pipe and aftermarket camshaft on my 2018 Bonneville T100. I'm still in the process of embedding the camshaft but look forward to the higher mid-range torque and approximately 30% increase in brake horsepower. I also plan to take to a local dyno service to install a Power Commander and optimize the ECU with a richer map.

The only other engine performance modification I'm considering is to de-snorkel the air box and install a high-flow filter. This should deliver incremental BHP as well in the neighborhood of 5% based on data I've seen.

So my question is do I really need to de-snorkel? If I go ahead and re-map the ECU without de-snorkeling, will I regret it?

Just trying to sort out the pros and cons and thought this might be a useful forum for discussion.

These questions just seem to keep coming up. The search function is your friend. If the only information one gets is from purveyors of "performance" parts, then these are the things that get purchased and installed.

Your bike's air induction system is already very good indeed. None of the after market "performance" "high flow" systems can beat that big updraft dry filter. A system flows well or it doesn't. Yours does.

For what you're spending on the 900cc, you could have had a T120.

The extra money, coulda had a t120 comment pops up a lot. Main problem with that logic is the t100 is a better handling bike.
To de snorkle takes 30 seconds. Do it. If you don't like the slight intake increase and supposed power increase put it back. Its 1 screw.

The Street Triple handles better, has more power and here in the UK costs less money than the T100.

Logically all T100 (and T120) owners should be riding one of those instead


.

Whenever I see a bike advertised with 'a shed load of extras' I often wonder how well it handled with a deckchair, lawnmower, some hose and a rake strapped to it.

There is absolutely no "logic" when it comes to either choosing or modifying a motorcycle. There are simply too many variables, most centering on personal perceptions of what a motorcycle is supposed to do and look like.

I have done the Tec cam and Xpipe.... it took me 5 mins to de snorkel.. only one torx head screw... for me it was good... for you it is 5 mins work to find out..if you don't like it..then its ten minutes work all up if you re install... simple answer for the snorkel question.. i have original filter in it at present so can not answer that part from experience.

For me the sound alone was worth the 5 minutes to remove the snorkel.

Lucky your not on my payroll mate. 5 mins! Step into my office.
The filter for me is just not worth it. I'm not letting more unfiltered air into my bike. Someone did a dyno on an aftermarket and found it lost a little. That was in the war and peace sized epic thread on cams.

Absolutely correct that a filter change alone has a marginal if any effect, true on almost all brands of bikes forums.
But with a DNA you do not give up filtering quality, they are just like a K&N but enlarge the surface area of filter media for increased flow. I would not use an MWR filter as they are simply a thin pc. of oiled foam. They even have a disclaimer on that for their racing filters.
Without further intake mods there will be no gain, removing the snorkel according to some tests will offer a small percentage and measurable gain on a dyno, but in real life you probably won't notice it, except for that growl which your brain may interpret as going faster. There is probably more difference between a dirty filter and a clean filter than two brands of air filters.
That all said some bikes with specific air boxes can significantly benefit from a filter and intake upgrade, but the 900cc WCTwins have the same volume airbox as the 1200cc bikes with 2 throttle bodies. They, even in stock form are getting more air than they can use.

But if you are like me, you change the filter to a HP one after the original wears out and remove the snorkel just to maximize the air flow and add that little growl.

Yup it was @jsobell - oh and BTw was 4 mins talkin' to my union rep about whether i was gonna start a demarcation dispute if I did the job - 30 secs trying to find a driver and torx bit - and 30 secs actual work time..lmao. Fun fact.. i have now spent more time answering whether a snorkel remove is a good idea or not, than i did in takin' the dang thing off..chuckles.
