funny seriously though its a really solid engine with a smooth power and very strong , personally i like 86 pipe with medium round header on most all novarossi engines and this one is no exceptions .

I run a Novarossi 9853 pipe with the short round header.

The Plus 4 has a very smooooooth powerband compared to the 21-5k. The 21-5k has some more bottom punch.

53 w/ short header is another great combo , a touch better in the truggy make sure you use short header with 53 pipe .

well from what I have seen out of my stock 21-5k You WON'T be dissappointed. I have run mine with the three lower JP pipes(1, 2, 3) and out of them I like the 3 the best. I have been meaning to pick up a dynamite 053 to try on it. You can't beat those pipes for the price.

I have a nova 053, but the header that came with it is that the short header? how long is the short header and i will measure it.

got this puppy today and it started right up first time. i dont really know how it compares to my Ninja Jx.21 it feels like the topend will be better but not sure yet, got a nova 53 on there and it seems to be a good feel for it.

Novarossi Factory Tuned engines are the same with more rotor timing. Wont be as good all around as a JX21. It wont be junk though either. Only bad thing about novarossi is the 1 gallon before its broken in.

Yes they take a long time to break-in but because of that they last forever. The pinch in an os engine would be gone two times over before the pinch of a nova is gone. Meaning the good pinch. But from what I have seen os engines runb remarkably well for not having any pinch. Nova's are strong too. I love both brands.

we will see during the racing season..it gets on the pipe pretty quick, and i think i will be just as happy with it as i am the Jx...but man is the ninja smooth
