i have a n2001bf 3port.... recently discovered that the piston skirt on the exhaust side was chiped out!:cry:...it runs fine but will not hold and idle!...it idles for a couple secs and then dies,no matter how much i turn the idle screw!....will it ever idle again,with the chipped piston?.....i really liked this engine!...does any1 on here have an extra piston they can sell or p/s set?...i dont have much $:(

There's only one way the piston breaks around the skirt area ;)

Piston/sleeve set is like 70$ I believe , don't quote me on that though

yeah i know:flaming:...why is it that the novas are the only 1s who dont completely mill off the back side of the back plate!....i have taken off backplates more than 100 times and no problem! then all of a sudden bam!....i hate myself:flaming::lol:

Toro Team
 

Wow broke in a toro team and raced it today, let me tell you something, it great, It's really similar to the FMS plenty of we'll everything.....

I know it's expensive, but it is just about perfect. I do think they should include a .10 shim in the box to replace the .20 to lower the head for 25% though, minor gripe. I found one from an old p5 and there you go. Break in took a bit longer with the billet piston, but not too bad. I geared up my Mugen Mbx6 to a 14 tooth bell from 13, and put my favorite 9853ss pipe on it, and there you go.....Blazing fast, easy to tune, I freakin love Novarossi engines.....

I second your statement, I have been running mine as it came out of the box on 25% with the 41029 header and the 9901SS pipe with strong results. Seeing as you have stated a change in head shim maybe I need to look into that as I may be lacking and not knowing it. Is the 9853 a better pipe then the 9901?

Thanks
Sean

hi guys need some advice on my nova 21-7bt,i run the engine yesterday on the track,but seems kinda weird it doesnt accelerate fast and cannot peak on the stretch,im using a 053 pipe,aluminum clutch shoes,1.0 mugen springs,am i using the wrong pipe on this engine,i bought this engine bnew and its fully broke,and other thing is this engine has the toro nero,plus 4 carb on it.

The 9853 will have a little more power at the cost of fuel economy. It depends on what u r looking for, as to better or not?

LOL well no need there then as I have tons and tons of power from this bad boy LOL:nod:

losi Re 10
 

Anyone try the losi re10 pipe on the nova plus 4 p5xlt or the fms yet??? For the truggy

I got the 2084ss/41021 combo on my FMS that I just started breaking in,I just barely ran 2 qts thru it and it feels really good, tune isn't even close to what it should be and neither is break in. Anyone thats been saying that its weak on low end power is full o' bull poop!!!:nod:

:lol:

I've run the RE10 with the 41020 header on my FMS in my 09 XT8 when I don't have my +4 in it. Really like that combo!

can i use the novarossi 21-7bt long stroke turbo button on my nova plus 4?

What's the correct shimming of the plus 4 engine?
It's used and came with 2 copper and one shinny one.

Should be two .30mm aluminum and one .20mm copper , if its older it could have been shimmed at .70mm ('08 version) .


.70mm would be more ideal for 25% if that's what you are using .
