I installed a 135 jet after I put my snorkel and exhaust on. If you know anything about a carb, unlike me, I would recommend it. I noticed a big difference in power, but still a little sluggish and backfiring a bit. I have been told to adjust the carb, but I know nothing about a carb, so to the shop it will be going. Good luck

Jet Kit

After i put my snorkle on I lost a little power and had the hesitation in the throttle response. I got a Dyno Stage 1 jet kit. After I installed it I had great throttle response and a good amount of more power. Im glad I bought it, it's great. Ebay has good deals on them.

maclove73 what kind of jets are you running in the bike now with the aftermarket exhaust? the oem 135 jet and some carb adjustments should fix you up. also looking at your picture's the snorkle looks pretty close the the exhaust pipe.

progigger some people have good luck with the dyno kits and some don't. you also have to watch out for the fake dyno jet kits on ebay, there are alot of them going around.

Everything in the carb is stock, never been touched. Dirty4man, I had to build another mounting plate for the snorkel, the one I used in the pic was too thin. The tube that runs into the airbox is not as close to the exhaust. Plus, when I installed the Supertrapp IDS2, I wrapped my entire exhaust with header wrap from where the headpipe mounts to the engine all the way to muffler. This cuts down on alot of the heat produced by the exhuast. You can barely feel it on your leg (95% of the time I wear shorts) after you have been riding on trails for a few hours. Got the idea from Highlifter.

that header wrap is bad for steel headers. it makes them rust real bad, it holds moisture/mud in against the pipe. not good
but if you have a SS header then its not to bad.

You can get them in any length, they cut them off of a big roll.

Here's are all the vents. on the foreman 400 and 450 all the vents are ran up front and hooked into the top of the frame just under the pod.

front and rear diff
front and rear brakes
fan
carb
fuel tank cap

Thanks for the reply on the vents Dirty4man. Those of you that asked about them, Dirty is right (he is the one that explained it to me). I built my snorkel off his design, just attached the vent lines to the snorkel is the only difference. If you turn your handlebars to one side you can look straight down at the frame and see the lines attached to the frame. On mine, five were attached to the frame (front diff, rear diff, front brake, rear brake, and fan). I used tee connectors to connect the rear diff and brake to one line and then to the snorkel, then the front diff and brake to one line then to the snorkel, and the fan vent line was lengthened and attached to the snorkel. I lengthened the carb vent line (located under the seat) run it under the tank and up into the light pod.

from what i've read you are suppossed to run the vent lines into the snorkel. when you bike is running you'll have a vacuum inside the snorkel. you just want to run them into the headlight pod or run them up the snorkle but not tie them in.

The only vent lines that should not be tied into the snorkle are the carb vents. It's ok to connect the other vents to the snorkle.

mtp0007, if you attach your carb vent line to the snorkel, as the snorkel sucks in air it will create a vaccum and suck fuel up through the vent line. The purpose of the vent line is to let air into the carb to help push the fuel through.
