carbs gs1000

[KEITH KRAUSE]

I haven't run vent tubes on the bike since the early 80s...so I forget what it is like with them! Cross winds, rain etc seem to make no real difference to running..and I have been through a bit of weather in my time....

It depends on your set up as to how much you'll be effected.
I have the tubes off, but if I hit a good crosswind the bike will act like I hit a sudden headwind and slow just a moment. If the crosswind continues, I'll experience the effect longer. Otherwise, it's perfect.
The Dynojet instructions require the removal of these tubes and warns California riders specifically.
I have the K&N chrome ovals and they have the ability to be mounted so they are not all exactly in line with each other. I turn the middle two "up" and have the outer ones "down". This helps the middle two flow a little better in my opinion. The filters don't block each other as much. What I really want to mention is the crosswinds seem to have less effect now. I don't know why the different arrangement helps, all I know is it does. It's not a big deal either way. The main thing is having the tubes off in the first place.

I have K&N chrome ovals, but they are one filter to two carbs..a big oval shared filter. maybe this makes the difference. I have not noticed any cross wind effect in 20 years, well at least as far as tuning goes..some of those winds do make the bike lean over and move around a lot!
