Bad engineering practice

just reading the snorkel removal thread ,and it is in my opinion not only bad practice, but completely unecessary to have a great oval hole open to the elements in your airbox. imagine if that was your car running that set up bad idea ,what i did was modify the snorkel to flow more air and protect my airbox from water intruision,and it does happen no mater what you read here,I road tested the bike and its probably my imagination havent done enough miles yet, but the mid range feels stronger and its staying in ! comments .

stock snorkel





modified snorkel

I say ditch the whole affair for individual air filters. Why waste time with the airbox and snorkel when it has been proven that the individual filters make more power with no downside?

I did the snorkel trim thing at first too. Bike went from lean to super lean and felt like she only wanted to rev to the moon, nothing at the bottom or mid whatsoever. Tried to rejet, broke my carbs, got a new set, rejetted and did the KARK.

Pabonne,

Broke your carbs? What happend? I just received my Polaris bellmouth but I am waiting to install it till after I get my pipes and re-jet. Did your re-jetting go bad? What should I avoid?

yeah my bike is not running lean so iam in a different position to start with, and i cant see how putting the snorkel back on is going to make it leaner, i would think richer,but if it did run lean and it should not ,that would mean iam flowing more air ,and an increase in jets size would put it right but thanks for your comments its interesting..

I am sorry you broke your carbs. However, what I find interesting is that your bike went from lean to super lean ...... that would tell me that it was pulling in more air (maybe?).

Wonder what would have happened if you would have followed that path, and simply installed larger jets to compensate for more air?

I'm no tune up expert...just asking a question.

Unrelated to the snorkel, just provided impetus to remove the airbox since I had the carbs out already. I broke the carb casting trying to remove the anti-tamper plugs covering the idle mixture screws. DOH!

Maybe I confused things here... I went from lean with the "in-tact" snorkel in place, to even leaner with the trimmed snorkel in place. I never tried it with the snorkel completely removed because I felt like I was just making things worse instead of better.

Probably would have been fine. But I got the carbs from SCCTrim and he through a couple of K&N cones in on the deal. So I re jetted to that set up and the rest is history.
