Anyone with suggestions as to how to keep a 421B engine running for longer than 5 minutes? A bunch of bought this engine and it just wont run for any of us. We've tried medium to hot plugs but nothing works...at idle engine flames out when hot.

Was wondering which NovaRossi parts (piston/sleeve/bearings/crank) are interchangable with the NovaMega EVO4 MS?

Is it possible to use a P5 case with on-road Piston/Sleeve and use it for on-road?

Is it ok to use a off-road engine for on-road?

SalvadoriRacing

crankshaft is also different..............the carburettor as well, but i think you can tune the engine with the offroad carb......

kitracer

Try using a longer manifold or more angle one.

Thx for differentiating the tuned and normal version.

Another question? what's the difference between 2015, 2017, 2018, 9901 & 9886 pipes?

Thx.

Hi guys! Does anyone know the factory needle setting for the NOVA P5X Buggy engine? Thanks in advance!

i can't answer you're other questions but i have seen a few off road 21's used at our track. the powerband is lower in the rpm range and they don't have the same top end but they work. the smaller the track the better they will do.

I'll be using byrons 30% fuel soon, but I don't have any info on my Novarossi PT21 SP1 engine as to how many mm and how many shims to use for it. It's an older top engine as seen here:

SalvadoriRacing

as far as I know every .21 engine is properly set to use 25% nitro (except for rally game versions).......you should be safe with 30% but if you really want to avind any risk put another 0.10mm shim........

Sounds good I'll get two just incase. Thanks a lot!

SalvadoriRacing

if you set the head clearance too big you end up leaning the engine too much to get a good performance and it will be dificult to get it running at reasonable temps...........

When I ment two I ment an xtra one just incase. What can happen then if I run it with 30% stock will there be any signs I should look out for? I'll take the head off to see if there are any shims on there.
