I just broke in my Axial .28 and I have a couple of concerns.

First I sealed the engine up with copper sealant just to be safe. Got everything installed and went to test her out. I used the heat cycle method and broke it in. I followed directions to the T. After every run I set it to BDC and all. And my temps are at a constant 235-240 degrees. Here is what I noticed.

During and after the break in I notice a bit of garble in the sound of the engine. It starts no problem and and is producing lots of smoke a full throttle. It is sooo powerful and super fast however , again the engine just dosen't sound smooth like it should be. At least compared to my stock engine. Almost like there is a small bit of water bubbling through(that kind of sound) It has never been near water yet and it was a great day.

Also, yes it does do wheelies an all no problem. However, if I let it sit and idle for a minute or so while checking temps or If I refuel it and I restart it. The power isn't there at the beginning. I know that it probably needs to be warmed up first but even at a warm temp and I restart I just dont have the power at the beginining. After a few min of driving and opening it up a bit then is when the power returns.

I also looked over the engine and it is as dry as could be. Thinking that there may be some kind of air leak.

I just dont know. Here is a couple of videos. I hope that you can hear what I am talking about with the sound of the engine.

I would appreciate any help. I know this problem is not letting it perform up to it's full capabilities.

Thank you.
