Re-Routing your air cleaner

I've been thinking about getting rid of the stock air cleaner on my elite E... has anyone run a flexi-hose from the back of the carb, into the under seat storage compartment and put a filter there?

I'm thinking it'd be
1) quieter
2) less likely to suck up rain
3) less of a pain in the * to get the air cleaner off for repairs

What would be the drawback to this (aside from less underseat space)?

if it was under the seat it may not get enough clean air, and it wont reduce noise, and the very small amount of rain that would get it isnt going to affect the performance because it would be absorbed and dried... i think you would be wasting your time

A fair assessment, thanks

Don't use flex hose, you want the air flow to run smooth to the carb, you can't keep h.p. quiet.

If you want to run a hose, it would need to have smooth walls. Problem is that 2-strokes want short air intakes, so it might be too long.

What's wrong with the factory system?

There's probably ~nothing wrong~ with the intake...

However, I prefer dry paper filters to the oiled foam filters. Additionally, it seems like every time I have to do anything to the carb, the kickstart/drivetrain, anything under the air cowl... The Air box has to come off.

Granted, I should at some point stop frelling about with it, set it, and ride it...

I thought perhaps for cosmetic and ease of maintenance purposes, that this might be a decent plan.

I just came up with another reason it's not... the carb is on the "Swingarm" and will move independant of the seat bucket, so that hose will be moving all over, messing up the airflow.

What about those short, stub nosed conical chrome filters (like the ones on the slightly larger performance carbs for the DIO engine)? I know that they're a lot less quiet, but they're not so "In The Way". Any of those small enough to fit on a stock sb50p carb?

Do a search in Perf Tech on K&N, there's one that I found that works, p/n is listed. That said, you have to upjet a bunch to get it to run that way. I never could get it to work right, though some have.

yea. im gonne start running a foam filter, after research i found out they work well on aeros with a stock carb...
