The buggy engine is still too new to tell. The powerband with the 2100 and med short radius is very nice.
I did pit at 10:30 in the truck with the 2108 and med header so it's doable.

fired up the clocked fx today for the first time.....fired right up with the factory settings... just had to give it a little throttle.....had to run a pretty high idle with a sleeve on the head to keep the temps up.... i do 2 heat cycle fast idle tanks on the box before i run it on the ground at all.... tickled it just a little a couple times with the trigger and even though it is rich seemed really responsive...gonna be a BEAST!!! using bones break in fuel for the first time as well

Running 30% Byron's. And I haven't changed shims from the box set up. Runs great as is. I will eventually experiment with head shims I'm sure but really don't see a need now as it's performing flawlessly. You know the old saying " if it aint broke don't fix it"

2013's and 2058's are all I need. Looking forward to trying this engine if I ever get my hands on one.

Welp! Do any of you know the stock middle speed needle settings? I have mine flush against the carb, but I have a nagging feeling it's been changed (I had some help breaking in my engine; guy mistook the middle speed for the idle, lucky I stopped him before he went too far).

Well, I'll welp you ;-). It should be flush with the carburator house so everything is good :-)

So Frank If you had to pick. Ninja JX21-B02 .21 Off or the FX Royal?

Power wise
Run time wise
Carb wise

Love to hear your input. I looking over some of your Speed post about the Ninja JX21-B02 .21 Off.

Thanx sir

Either would be a great choice. Personally I always choose new tech over old tech, sometimes that bites me in the a$$ but the FX engine has been a great engine. The FX like most engines is very pipe specific.

I am still getting the truck dialed in. I am currently running the 2018 with med header in the truck and I was able to pit at 10:35 at amain hobbies (med-loose, hard packed, long straight)

In but the buggy shines with a 2100 and short header and it screams with power everywhere. The engine is still very new and was out of fuel at 9:30 when I tested it in practice, but I think this will improve as it loosens up.

The overall quality of the FX is very high end, its not flashy at all but all the parts fit and finish are very nice. Power is very comparable to the ninja. I think runtime will be up a little over the ninja once it breaks in. The FX idles better than the latest speed engine (if thats even possible) The FX carb is a little more precise more like a nova carb (small adjustments) Both are 3 needle and an easy tune. The only thing I am not thrilled about with the FX is that it takes 2x as long to break in as what I am use to with speed engines, not a big deal just an observation break in is more Nova like IMO. In the end I would go with the FX but I think you will be happy with either. BTW are you putting it in a buggy or truck?
