Just get the 41001 manifold and all will be good

[QUOTE=powerpig Now reading this form maybe a far better pipe combo???[/QUOTE]
I drive my serpent SRX8 on a smaller track that is technical and about a 90 foot back straight. And then there I drive at thunder alley that is huge with long straight, huge everything. My keep off 4 with 41021 and 9901 is just fine. I'm am not the worst driver and nowhere the best, but I think you can get better gains messing with clutch rather than a exhaust manifold. I've heard Kortz quote in a video once, that guys worry too much about the minor things. Just learn to drive first.

What size carb restrictors you guys using in the mito4 ? I got the pre run version and it comes with the 5.6mm anybody else using that?

Ran a 6.5 last weekend and was able to get 10 mins on a slower technical indoor track. I still had too much bottom end power will most likely go with the 6 or 5.48 this weekend.

Anyone knows the measurements of the rear bearing for the Nova Drake Edition.

14.5x26x6 . . . .inner race is not offset. The Nova bearing (steel) is 16003. I am looking at a ceramic boca bearing for mine as tko only has that size in the offset race.

Hope that helps.

So , what is your opinion on the nova direct website engine offerings ? What would be your pick for buggy on a med track with good grip ? Why ?

Mito 4 for the power and gas mileage. If its really decent grip I would try the Bonito, because it has killer medium to top end speed and super easy to drive on the bottom end.

I have a question about these two engines !!!
Ultimate M5 and Novarossi P5XLT.
Two Engines Made in Novarossi

The engines are the same or have differences between one and the other. In internal engine
In terms of practical regime are equal 6000x36.200RPM.

if its only 150' straight you should be ok

2096 is the other great option

My understanding is you have to be one hell of a drive to notice a difference. I think Elite 5 value wise, and Mito 4 most popular. I choose Keep off because of the 2 needle carb ( easier tuning for me ) and a few other racers in my club running the same.

Came across this BX21 in a parts lot. I noticed it has the numbers 1000 111.
on the engine flange. wondering if anyone knows more about the numbers . I.E. Modified by? Limited edition? any other ideas as to the meaning of the numbers.

Thank you in advance.

Picked up this older novarossi BX21 with a buggy and noticed it has engraved numbers on it. 1000 111 on the engine case flange. Anyone know what they mean? limited edition? Modified? If so modified by who?

Thanks in advance.
