    Are you talking about the little screen that sits on the very end of the exhaust can? the one that screws into the tail end of the exhaust?

    Because if you are ... then you're going to be okay!

    That little screw-in screen in the back of the muffler is an additional "noise suppressor."
    (see parts # 18 and 19 in the following parts diagram.)

    The spark arrestor piece that makes your bike safe for riding in the woods is *INSIDE* the muffler and can't come out.

    Yes ,parts #18 and 19. Tell a Forest Ranger in the Gilas that is not a spark arrestor:eek1. Guess I will wire it in this time.Those big threads are a dead giveaway that something goes in there.

    Unlike their seats, which I love, I have only heard negative things about the tail rack. I don't think they make it, I believe they are just selling someone else's product. Someone on this thread tried one and posted that it didn't hold up. If you look at how it is trying to carry all the weight with a little bit of cantilevered support, it just looks read to fail. The Pro Moto Billet rack is the way to go, but it is pricey. I am saving my pennies for one.

    Hi fast

    SeatConcepts does not build that rack. I use the GiantLoop tank bag on my 500 and a front fender bag for a spare tube from Dirt-Bike-Gear. You could also use a DBG rear fender bag that attaches to the rear fender....OR a GiantLoop Mojave for day rides. I use the GL tank bag, front spare tube bag and for longer day rides, the Mojave.

    Good luck
    Garrett

    Just leave the screen out & screw the nut in, tight! You're then legal, let him do the stick test, as mentioned the spark arrestor's inside.

    I can confirm this works. I set my tps to .640 at the closed position and can now chug at low rpm without worrying about stalling. You can chug then pin it. I also use the jd tuner at recommended settings. Super easy adjustment.. only took 5 minutes. I have alot more confidence in the bike as I can now stay off the clutch. My TPS reading at full throttle is 3.9v and does not matter.. the bike pulls hard.

    I have no time on my new 500 yet but been reading some on tires

    it comes with Maxxis cross SI 7311 on front -but doesnt use the mate which would be the 7312 for the rear?

    instead it uses Maxx enduro 7314 on rear
    its mate would be the 7313 for the front

    WHy you think they did not use the matched tires ?

    If it is that easy/straight-forward of cure or improvement in rideability ... why doesn't it just come that way? :huh

    Emissions reasons ....?

    Thanks for the idea boostracer:clap. I think I will safety wire the ring down to an endcap screw also though.Anyone make a nice little end snorkel that directs that heat flow down away from my right turn signal?

    Does the "FI" trouble light still stay off after you change the TPS position?

    lol so as you can see Im a little freaked out about loctite. I know Ive seen some posts about it but cant seem to refine the search function enough and Ive been reading for way too long in too many places to not find an answer yet, so here I am.

    In the manual my loctite shop supplies should include -
    loctite 243
    loctite 2701
    loctite 648

    If I look at any stores or online I cant get the numbers to match so I have -
    loctite 27010
    loctite 24010
    these are both gel type which is really nice to work with, stays where I want, easy to deal with in general.

    I think I read that theres differences between whats listed and what I can get is because its European numbers vs. US numbers. Does anyone want to rehash the loctite info for me again please? What Im most interested in here is what to use on the sprocket bolts for the rear wheel, counter shaft sprocket, brake rotors and caliper bracket. I plan on doing alot of swapping this year from supermoto to off road set ups and really looking to do whats in my best interest on keeping it quick. What is also sending me for a loop is the coloring and I guess what got me thinking I might be using the wrong stuff. The rear sprocket bolts came with what appears to be green, the rotor and caliper bolts appear to be blue. The 20710 that I was using for the listed 2701 is red and the 24010 used in place of the 243 is blue. Have some green in the toolbox but it said for use after the fact?

    On another note, while looking through the manual, on page 13 there is a picture of where to locate the shock absorber part number. They show a sensor bunged into the exhaust. Does anyone have this? Ive asked somewhere before how exactly the EFI on these bikes performs its duties and Ive ALWAYS seen exhaust sensors on EFI, but not on my EXC. Is the system just a glorified carb where its not really sensing and doing all the functions it could be? I recently put the FMF mega bomb and 4.1 system on along with the twin air power flow kit. Reset my JD tuner back to how it came (suggested settings, not stock settings) and the bike is a complete monster now. Every and any issue with flame out or stalling while chugging at little to no throttle input has been eradicated. I did set the idle setting on the tuner up a bit until the idle smoothed out. So what Im getting at is on my SXV if you do anything like exhaust etc... you need to map or tune it in some way. Is it critical on the EXC? I just don't want to run it and burn a valve or something or run it in a bad fueling situation. I have a dyno tune scheduled in a few weeks so Ill report back on what we find out as far as tuner settings and F/A ratios across the board but in the mean time Im just looking for some input on the EFI and how its doing its job.

    Thanks for reading, thanks in advance for any help.

    The efi system is really not the best system on our bikes. It is not a closed loop system and won't compensate for altitude. It does some for temp but if running in too cold of temps it will overfuel and get gas in the oil. This is what the guys getting snowbike kits are dealing with. Currently a few guys are testing out a dobeck controller that uses an o2 sensor and will constantly adjust afr . Making it a closed loop system. Nice system and not too expensive. Not sure when it is going to be sold. I will also be switching out between dirt and supermoto. I would also like to know what locktite guys are using.

    Did not know it was an open-loop FI system on these bikes.

    Installed the X bushing and also got the same. About 1/2" lower seat height where i sit. I'm guessing Synergy Seals are measuring the change at the rear of the seat for marketing reasons.

    What are peeps running for handlebars? I bent the stockers and would like something with a little higher rise. Any hot tips?

    Try moving the handlebars to the forward position before doing anything else. Ride the bike for at least a day to get used to it before you change to something different . It made a big difference for me on steep downhills.

    What Bengt said, position 4 plus Pro Taper Pastrana Freestyle bend. Those are great tall bars.
