Hey there Russ. I can't help you but am pondering the same question. I think the pod type setup looks good but am wondering if riding in the rain has any effect on that open filter element.

I've been really happy with the K&N direct swap for stock but it does mean I can't tear out the airbox and reclaim that space.  However, it is better protected from the elements.  I am considering pulling out the rubber intake boot to increase flow.  Someone mentioned that in another post.  I'm just not sure how much difference it could actually make - nor if I actually need it.  Flow seems to be pretty good now.

I have seen (Be_Savage I think) that a Raask pipe and a removed snorkel gives 32 bhp (didn't say if it was rejetted) compared to 24.6 std. This changed the 0-62 time from a quoted 8.1 to 5.94.

Not sure how reliable these numbers are.

When are you noticing the leanness?  The main jet realistically only effects WOT (3/4 throttle and up).  Most cruising (unless you're going 70+ on the highway!) is more effected by the needle.  And 35-50 in 5th is effected some by the idle mixture screw along with the needle.  Of course there is overlap on all the circuits and so many factors that the right jetting should be different between many of us depending on where we live and the altitude we ride.

Just some things to think about!  You can use everyones more common jetting settings as a start, but be prepared to spend some time playing with the carb to find YOUR best setting.  Try to do it spring or fall so that summer and winter won't be too far off, as it WILL change with the season and with altitude.  

That's the big plus of the Supertrapp, you can 'adjust' your jetting throughout the seasons without getting into the carb.  Just add or remove disks.....they also make similar items for airboxes, check out this link:

could be a fun winter project to make something that does this.....

Not sure who you were talking to Greg but if it was me, mine's a bit lean on the top end and seems to be year 'round.  I have a 152.5 in it and was considering bumping it to a 155.  It's easy enough to play with and I have several jets in a plastic box.  Just not sure if I have the 155.  I think I do.  No rush.  Gotta get her started first.

I've removed the rubber snorkel several years ago. The effect will be that you have lean running Savage (try riding without the side-cover of the filterbox, that has the same effect). After removal of this rubber snorkel I enlarged the mainjet to a 165. It ran great, great torke, great sound.
A few years later I drilled 4 holes in the exhaust of 6 mm each. And I enlarged the main jet again till 170. A year ago I had to take the cilinderhead off and I flowed the in-letport. Now I'm driving with a 172,5 mainjet but the carb needs to be rejetted by a professional. And I need a new exhaust (The one I've now is kind of rusty...) so when I've changed the exhaust I'm going to a tuner for a better jetting off the carb.  

The top speed didn't increase much, but the torque is much better. The tuner will make a dynojet-run which I can post here.
But I'm still saving some euro's...


At this moment the bike is running very lean with a little throttle and probaly much to rich at full throttle.  So I really have to get this bike rejetted by a prof although it is riding fine.

Haven't had a chance to troubleshoot the electrical issue yet.  Life has gotten in the way.  Hopefully I can play with it some tonight.  I've had the battery out and on a tender for nearly a week and it seems okay.  No notable breaks, abrasions, etc.  No loose connections.  Fuses are good.  We'll see.  Anyway, I definitely have a good increase in top-end power since the rejetting/muffler change/air filter change but plan to try the 155 main when I get a chance.  Unfortunately, I can't add a baffle to the MAC - at least it's not designed for it.  I wish it had more of the base thrum of a glaspack than the loud rumble it has now but I still like it a lot and the increase in power is good.
