Here's the deal I have a gtr 3port modded and I have not ran or broken the motor in yet. I also have the same motor not modded but I am currently running it in my zo1B. My ?s r has any one ran one of these modded? And if so how does it run? How did u break it in? What restrictor is being used? And what chassis is it ran on trug or bug? I plan on breaking in the modded one in very soon and I would like some input please.

Has Anyone Else Bought The New Pipe Yet? Curious To Here opinions

Got one on the way just now, I will post results when I get them. I have had good results with the VP-Pro RS-1 and RS-4 pipes with this motor so far.

Great engine

i recently got one of these engines the other day taht had basically only had the break indone. currently its only had about 3 litres on it. it seems i have the V1 carby on it tho because i cant get it to "rich bog". i have the top and bottom needles almost flush and the engine is still lean.

what other carbies can i put on this? preferably not the OS 21J cos it is worth more than i paid for the engine.

Set the mid range 2 turns out from flush pointing at 2 o'clock. Then the Arrow V1 and V2 carbs will run just like an OS and idle for days. :nod:

i have done this and then set the HSN and LSN so rich they are almost falling out and i still cannot get it to blow smoke, the engine is lean and if i put my fingers over the needles the engineblows shitloads of smoke and dies in 2-3 secs.

Sounds like bad orings on the needles....

Yes, install a new o-ring kit. OS o-rings will also fit. Then put a drop of thread lock on all the needles so they do not vibrate loose.

I recently put the 3+2 sleeve,rod and piston set in a new arrow crankcase. I can get it to idle, but once I try giving it gas it dies. I have tryed every needle setting they all have the same effect. Any help? The motor bearings are all new same as clutch and clutch bell bearings. Anyone else put the 3+2 sleeve in? The sleeve barely sits flush in the case. And can't get to go any farther.

Check the shims and see how the compression is.

The compression is tight. Because its new. The shims are how they come from the factory

Any help?

I have no idea unless you put the sleeve in backwards. It ran fine in my old arrow GTR-21. The sleeve is supposed to sit above the case, same as with the 3 port sleeve.

The slot in the sleeve is aligned with the pin in the front like it should. I was able to get to throttle up but still not running right. What is the factory needle settings again?
