I've ran mine since they first came out. Here in FL, we race at least 3 or 4 weekends out of the month, so I would say that mine has at least 4 gallons ran through it. It is a fast motor .... ran past a Murnan 12+3 out of the corner...down the straights, and runs a temp of 220 (on an exergen) and getting 5 1/2 min on a track that is known as a motor killer.(your on throttle almost the whole time)

after over 20L on my ninja, all looks fine but ahhhhhhhh

i have had two very hard crash on the manifold and damage the crankcase. but you can see a small hole inside.

man thats bad luck.
i just do this to my fls pipes

Well I guess that is a flaw I ahve had the asme on both the FLS pipe and muy regular pipe and the same with tmy crank case as well while at the GLC....

Oh, then i was thinking about the quality problem, i never had this breakage problem with the other brands (i only used NOVA, MAX, RB) even crashes the manifold to bend. Other then that, the NINJA had the most power and speed (to me)

Could it be that the stiff connection of the FLS is transmitting vibrations throughout the engine/exhaust, which have been dampened by the spring connection of the old one-piece pipes?

No, i'm using the Mugen 2501 pipe, (also show above) maybe the manifold was too stiff , the manifold not even bend but crankcase was break.

Boss and Falcon plugs are identical to the Mugen plugs...The Boss engines are a mirror brand of the Ninja motors, the Boss products even come on fancy plastic cases just like the Ninja products....... Boss=Ninja and Ninja=Boss

best ceramics to get for next year?

Acer

where are the boss products found?

What nitro is everyone running?

And what %?


Are the ninja's easy to tune, and do they hold a tune well?

I know I will have to tweak it and all, but in general?

What need to be done to the engine out of the box? I knw carb sealer, anything else?

tornado 16 or 20% never again will i run 30% but maybe 25%
in general i always take a new motor apart and clean it,the sleeve i use a round rubber bit on a dremal and clean the ports carefully oil and put it back together and never take it apart again.
and ya seal the carb this is a must.
break in look for mike's post on this thread way back.

I wont take it apart lol... That scares me

I dont want to mess it up, once I work with them more I will.... But not now, atleast not me doing the operation......

20%, the hot fuel at my track is Werks, anyone use that? And I will run 20% also, 30% runs awsome, but the wear on the engines isnt worth it....

It will be fun getting back into nitro

what's the differences between the MR21-R01 and the R01A?????
