air box mod - new way? reversable! / aftermarket exhausts.

Post by S2Mumford@aol.com » Fri Jun 08, 2001 1:51 pm

That's a great idea, too late for me... However, according to one of the KLR geniuses, the opening in the stock airbox has a greater area than the carb does. So as far as I understand it, the airbox mods do nothing? I would strongly suggest leaving the airbox totally stock. Also, in a high mileage application, Big Gun exhausts are a pain in the ass. They need repacking, and they self destruct at the front and rear of the can. I lost some of the nuts on the inside of the front flange. The folks down there have been really cool regards repair and replacement of their system, but I shitcanned it anyway and went with a Laser Produro. No repacking needed ever, stainless steel, sounds good. I will let the list know how it works in the long run, but I put 2100+ miles on it last week and I love it so far. I want to see the pics of Mark Cheramy's Big Gun which shit it's pants on the road home from Moab... Cheers CA Stu A13

You also have to consider the path the air has to travel between the air box opening and the filter. Relative to the stock opening the holes made by the mod will be closer (i.e. less restriction), so it "should" provide increased flow. In addition I have wondered about the path the ambient air must take to reach the topside of the airbox underneath the seat, and how much this would offset the closer proximity to the filter. I took some other advice I heard on this list and modified the air box cover, figuring I could always get a replacement cover if I wanted to undo my handiwork. Ideally we should be getting dyno runs and/or taking airflow measurements in the air box in order to quantify these modfications. I didn't do this myself either, I just started playing around. I have the Big Gun Quiet series, a 150 jet, 3 1/2 turns and air box (cover) mods. It sounds better an runs cooler, hopefully it won't foul the plug (time will tell). The weight savings alone with the new pipe makes it worthwhile, since I am endeavoring to bolt on a bunch of other stuff. What I'm wondering about is the screen in the airbox. I've heard people mention removing this to reduce restriction. I was tempted but have held off for the moment.

What is the average time(mileage)between repacking? The Laser is interesting. Is it any lighter than the stock exhaust? Looks a little less bulky.

The Laser Pro Duro is not much lighter than the stock muffler. I am guessing around 1 or 2 pounds lighter. For more information and pictures check out my review at: http://jlyonamf.tripod.com/LaserProDuro/index.html John The Laser is interesting. Is it any lighter than the stock exhaust?

Depends how you ride, but the way I ride it is about 1100 - 1400 miles max. The first time I repacked the BG, after about 2000 miles, you couldn't even tell there had ever been packing in there in the first place! I should qualify all my whining by saying I bought the FIRST Big Gun ever sold for the KLR650, and they have made lots of refinements and changed the design significantly since then. The man to check with regarding the latest generation of BG's is "The lister you've been waiting for", Mr. Andy Cohen. Take it away Andy!! CA Stu <-- didn't do a "Flying Wallenda" South of Moab, like some people did... -----Original Message----- What is the average time(mileage)between repacking?
