Since I decided to run without the air box lid, I'm installing the 158 main, 42 pilot, and needle clip on the 2 slot from the needle end, air screw out 1/2 turn more than stock. The plan is to start engine, let idle to warm up, adjust the air fuel mixture with the airscrew for best idle, set idle RPM with idle adjust, then ride and peroform a plug check. I also purchased a rev box from White Bros.

I just purchased a Pro-circuit T4 slip on and K&N filter with outer wears for my son's 400EX. From reading on the web concerning jetting - so far the conclusion would be to start with 155 main, 42 pilot, and needle clip on second position from the bottom, air screw out 3 turns. Dealer said to start 1 size larger on the main - 150. (Sea Level) The 155 main sounds like a good starting point - what do others think?

I will run them WOT in 6th gear and post pictures in March. I haven't changed the plugs since the bike has run good. I'll be removing the TORS system this week and performing winter maint ( oil change, filter check, polish the rims and chrome.

Those pictures were NOT taken after WOT in 6th gear! Those plugs have been in for 2 years - and the last 15 minutes riding was driving on the flats at mid trottle, followed by 1st gear idle through camp.

Bansheerider29X, From looking at my plugs from normal riding, they look a chocolate brown - thus I think the jetting is ok at sea level - but I'm going to check anyways with new plugs...will warm up the engine, change plugs, run WOT for 5-6 seconds then kill the engine and coast to a stop. Plugs will then be pulled and inspected - will also take pictures. Thanks for the TORS information - I will check the Toomey web site for removal help. It would be fun to meet up with the locals for a ride! I grew up in Murray and rode dirt bikes and 3 wheelers at Jerico for many years - the "pole" is a life saver!

I have a 36' Tahoe transport - so the plans are to stay in the Oasis camp ground JUly 5th - July 10th. I will buy main jet sizes 270, 260, 290, 300 and will do a plug check upon arrival. I want to remove the TORS system as well - need some instructions to do this. I will also have check my 2 400EX's as well. The 400EX's are stock, but I'm going to add a Pro Circuit T4 slip on and a K&N filter before the trip.

I have a 2003 Banshee with Toomey T6's, K&N airfilter, air box lid on, snorkel baffling removed. I'm planning a trip to St. Anthonys in Idaho and Little Sahara in Utah in July - and need some advice on Jetting. The elevation at St Anthonys is ~ 4900' to 5400' , and Little Sahara is ~5100'. My Banshee jetting is as follows: Mains: 280 Pilots: 30 ( stock) Needle ( stock position ) I've run it this way at Winchester Bay / Sand Lake (sea level) without any problems - runs great and has not fouled any plugs! According to the web link below, for a temp of 90F and altitude of 5500', the mains should be 2 sizes smaller, jet needle raised 1 clip position, and air screw out 1 turn. http://204.71.0.3/motoprof/moto/mcycle/carb101/carb101.html I've recently been told that 280 mains might be lean at sea level - and I plan on doing a plug chop in March to verify. I rarely run WOT - but have noticed that the quad doesn't accellerate like I would like at WOT. The front sprocket has also been reduced 1 tooth for "Duning". I just pulled the plugs that have been used for 2 years - and link to pictures below. http://community.webshots.com/album/207050119IVYybQ/1 Any advice would be appreciated - Thanks!
