    It’s more for sound to help quiet it down. Some have said the FMF has been melting the stock right rear turn signal and some say it’s been no problem how is there such a difference in pipe angle.

    Wait until you try it without the Q4 insert and the air box lid off

    It tricks ex pulses, works like a longer headpipe / stepped pipe,,,as in adding more low/mid and carring upper rpms longer.

    Basically it is a shorter headpipe that thinks and works like it is longer(like looking in a mirror ),like KB,, lol got ya,,,KB

    Maybe there is the occasional user that does not need the extra noise and every little drop of power.

    Does anyone else find it a pain in the ass to check the oil level with this shitty little dipstick that's wedged in between everything? My YZ has a site glass and it's so much easier to use.

    I get like a full quarter inch difference if the bike leans ever so slight while I'm checking it. I feel like this is a fairly necessary measurement though to be such a haphazard shitshow in terms of accuracy.

    I know know on the YZ, the manual is off by about 100 ml from what it states is should be replaced with oil + filter change. It's easy to check on the site glass though and I usually top it off until I get it where I need it.

    With the CRF I want to make sure im running enough oil for wheelies but this dipstick sucks. The manual says 1.15 L but I put in 1.35 L figuring I'd check to make sure it wasnt too overfilled but now I cant even get a reliable reading on the dipstick.

    I put in 1.22L by recommendation of the tech at my dealer. It's pretty easy to keep it close with the sight line on the side of the bottles.

    Correct, I was looking at liters when I typed that, I meant 1.22 quarts. Nice catch!

    Have only had the bike a few days. Coming from riding Harley's on the street the throttle on the L is crazy. Seems like it's all on or all off. It's not the slow response you get with a 850 pound street bike. I'm sure I'll get use to it but the learning curve will be interesting. I'm not looking to "uncork" it but would love to smooth things out a little.

    Is a Vortex the only thing that will help smooth things out, and how much will it help with a stock pipe?

    The vortex does not have a setting to be run with stock exhaust. The power commander does tho I believe.

    As far as the throttle jerkiness I dont know of other solutions. I have the vortex/fmf combo and love it.

    G2 Throttle, JD Tuner, and stock exhaust here. Contrary to popular belief, I can plonk along like a lazy trials bike all day long. Mine is as friendly way down low as my 250X is.

    That is exactly what I'm looking for. I need some details. How hard is the JD Tuner to install and set up?

    Does anyone have a Power Commander File that they'd be willing to share for the 450L with full exhaust? Just ordered the PCV and Yoshi.

    Installation isn’t difficult. Tuning one needs basic jetting knowledge as using preset, or ‘suggested’ settings, rarely works well, and can leave most impatient people frustrated.

    It’s a great tool that people tend to discount and overlook as most are in a hurry. Just my opinion.
