hi guys, is OS SPEED .12xz SPEC II legal for EFRA and is 3 port?
thanks...

Yes, and yes.

Sorrymaybe an old question but what's the best pipe for the OSxz blackhead and where do I start to look for one, Thanks for any help

Never mine found it OS 1050

hai..here i have a question..now i'm using os xz blue heatsink..i feel the motor are not powerful than before?the compresion is still tight..but the car didn't have top speed n the temp. are so high..148degree..what should i do?and i more thing..is there any side effect if a take out 0.1 shims..?i'm blur..

You are running the engine too rich. If you are reporting it right, 148 degrees is way too cool. You should be running temps between 180 degrees to 250 degrees, depending on air temps, humidity, type/size of track, etc. Get that temp up before you start doing things like removing head shims.

Before you say that, ask this question:

Are you running 148def Fahrenheit or Celsius?

He probably meant 148C which is nearly 300F, very hot indeed. Do not remove a shim if the engine is already running hot. You may have the needles too lean and that is why the engine is down on power. Richen both needles up at least half a turn and see how the power and tune changes then retune from there.

Didn't think about the Celsius angle. Thanks for pointing that out. I forgot that this racer may not be from the US (since the US are the main one that still us fahrenheit to measure temps). So, if he is talking Celsuis, he needs to richen it up and drop the temps.

thanks guys..u help me alot there..i forgot to mention 148'celcius'..i'm really new in this gp rc..anyway i'll try ur suggestion to readjust the idle..actually i'm from malaysian...tqvm

forgot to say that i already richen it and of course the temp will drop..but..the power of the motor also drop..thats is my main problem here..

Well, let's start with:

What fuel are you using?
What plug?
How much running have to done with this engine? 2 liters? 10 liters?
Clutch setting?
Do you know what the elevation is above sea level where you are?
What pipe?
