Wow..14mins run time on a buggy? Thats super amazing! I tried 3 tanks and it ranges from 9min 45s to 11 mins with a 7mm venturi. Temp was 120c when it ran out of gas. Of course the pipe plays a major part, but its the fingers and track layout plays a major part as well. As for me, im more than satisfied with the performance and i wouldnt take the risk. Better to pit at 7mins..

Just driving around the back yard. Engine temps at 210 or so. I think it rips but I can tell once it drops its nuts it is really going to scream. I used the WERKS break in method. I use that on all my engines. I have over half gallon on this motor with 30% WERKS. I am racing it this weekend broke in or not.

What pipe ru using? Have u tried the 086 or 2060? What plug ru using?

Yes that's in a buggy on a good medium size track medium grip as well...
I'm much the same but when you race against 5 of the top drivers in the country on a club day just to make the A, I need good runtime cause every little bit helps...

nice quote. racing kinda competitive now. not just the a finals. all finals are tough. the arrow give me better confidence. awesome motor. and it runs along with the big boys which left many smitten

Has anyone had trouble running Werks plugs in there Arrows?

This engine like to run with OS plug P3 and maybe P4.

you should be running OS plugs..P3 for steady idle, easier tuning, P4 for more power and better runtimes

I thought I would try the Werks plug and it seems to be running fine though. Only issue I had was it didn't seem to want to thread in the head correctly for some reason. Either way, just to be on the safe side I have a new head and some bullitt p3 plugs on the way.

Same with me confident that i'm going to get good mileage with plenty of power as well and it will run all day long without a problem at all...

Are these the stock settings for the arrow? Ready to put her on the ground after a little bit of break in time.

Be careful turning needles all the way to the closed position (never turn MSN/LSN to full closed).

The needles should be set from the factory, but here is the right settings for an Arrow:
-HSN: 3 turns open from closed
-LSN: FLUSH with the ball link body
-MSN: FLUSH with the carb body (generally, slot pointing around the 9 and 3 o'clock hour - though not always, so do whatever is flush)
-Idle: Set a 0.75mm idle gap with the venturi insert out! Arrow says 0.5mm, but once you fire up the engine for the first time, you can lower it as needed.

I keep OS plugs in stock so let me know if I can help

I ran a WERKS plug in the arrow and it sucked. Only running a P3 now.

The Arrow was ripping today. Love it. Running a WERKS 2057 pipe today. Love it. Sounds pretty nasty as well.

Now wE all know this 3 port engine run very good,is there possible they will have modified version like OS speed,or maybe 5 or 7 port?
