anyone know the stock carb settings on 421 bnx buggy eng?

i did it yesterday i used a material i found here, it is like thin silicone but is used for sealing pipes, it can "survive" in high temperatures and under any fuel contact

the engine improved the way it is working, although it doesn't drop the RPM immediately after you return the throtle to idle position, it takes some time less than before. Also the temperature of the engine droped some degrees C.

today (i think..) i will receive the o-rings for the tuning niddles in the engine so i will replace them too.. i have this will seal the engine totaly.

thnx for your help

what kind of exhaust system do you use on a long stroke engine?

i´m going to buy me the new NOVAROSSI PLUS 12-3 and it´s a long stroke engine.

Mielke 2501 mit kurzem konischen Krümmer geht auf meinem R12L3 gigantisch.

Schreib mir doch mal eien PM wenn du den Motor gefahren bist, würde mich sehr interessieren wie der so geht.

Ach ja, und wo kriegts du den Motor her und für wieviel?

Gruß, Stefan

hi stefan,
hast du noch was an deinem motor gemacht.
wir haben 2 jungs die hatten schon keine kompression mehr
nach ca. 3 liter.

dieter

sorry guys for writing in german

Hallo Dieter, ja meiner hat das volle SMG-Programm und geht gewaltig

Ich habe meine eigene Methode die microcasted Motoren einlaufen zu lassen und die hat sich hervoragend bewährt. Meine ersten beiden haben auch sehr bald Kompression verloren, nun nicht mehr.

yes I have the same question. I have 52607 pipe set sitting around. Would this be a good match?

Also, can someone plz shed some light on how Plus12-3 compare to OS speed 12 TZ tuned?

Can anybody recommend a good pipe for the Novarossi 35 plus 21? Thanks

the 2052 with the five fin conical manifold is very good combo!

I just received a Novarossi 2630 pipe and have noticed that the
inlet to the pipe is a smaller diameter than my mugen and max/nova pipe.
2630 fits loosely into my mugen and max/nova header.
Do I need a different header or is it supposed to be loose?

Thanks

PM ist unterwegs!

Ich überleg grad ob der Dieter und ich auch das Mielke 2501 haben. Ich weiß nicht genau welches Habbecke Rohr dem Mielke entspricht

For our english speaking friends:

PM is on his way!

I´m just thinking about if Dieter and I have the Mielke 2501, too. I´m not sure which Mielke Pipe is like our Habbecke one.

hey all,

do you run your engines under hight external temperatures? these part of the year here we have nearly 40 degrees C, should i protect the engine and not run it? do you have a threshold in air temperatur over which you don't run your engines?

if not is there any measure you take against the high temp?

antony

just put a #8 glow plug and let it go........

thnx for the hint,

do you you change the percentage of nitro in the fuel when the temp rise? i usually run my LL5 with 16% nitro.

Anyone have any exp. on Plus12-3 ? I am torn between it and OS 12 TZ tuned. Any comments would be appreciated!
