DAMN....I jinxed myself. Not half hour after I wrote my last post, I ran the engine and the red silicone used inside the crankshaft has come off. Nothing else seems to have been damaged as It happened at slow speed, but DAMN...engine will be out of commission and I haven't even raced it. Let's see how JP fixes this issue for me.
Well I'd like to report that Mugen will replace the crankshaft for me. I called em up and they simply told me to ship them the crank with a letter explaining what happened and they'll send me a new one back. They were very helpful. It sucks that it happened but at least Mugen is taking care of it.

Mine ran great this past weekend, in 90+ degree heat it was running at 225. On a tight technical track that I have limited experience on, I qualified 14th, finished the B in 2nd. bumping to the A main. Started 10th in the A and after 30 mins. finished 5th.

This is one of the best engines I've ever had, and stock! It has no fangs on the ports at all, and runs with modifieds.

Just ran my engine this weekend and I have mixed feelings about it... It gave my great low-rpm response but only that... Maybe it is not already fully broken in... I made about 10 tanks with my break in fuel and nad about 6 more with 16% fuel and it stil hasn't came to life...

So.. what I did, just put my NovaMax back and made the quals and finals.. Man, what a superb engine!!!

cheers...

I would like to retract the previous statement about the new JP FX3. This motor gave me nothing but trouble all weekend at our state titles. They are a waste of money, and the quality control on the motors is not very good at all( this is just my opion). I saw 3 of these motor damaged, and another few eat conrods like there was no tomorow. So guys I won't bother buying one again.

Default FX 12 T-03 (S)

Mine has been running great, and I've been very happy with it's power and performance.


However, the ramp they put in the crank came out today, and the engine wouldn't run, pulled the air filter off and saw telltale red paricles, and after removing the carb., you could see where the silicone, or whatever it is they use, has dislodged and is blocking the crankshaft opening.

Now there are 2 incidences with the silicone coming off the crank. It might be better to remove the silicone?

2 out of ...............?
All Fx's on my track are doing great, no problems here.
Also did you read your FX-instructionguide?

No I cant read French. But I will figure it out.

I was asking Would it be okay to remove the red paste from the crank, then there would be no worries about the paste coming off during a race.

The paste is a performance mod, the engine will run just fine without it, but it flows the fuel down the crank better with it.

Red,
when I saw the crank and how it was put in there, I can see that is was just for that to push or guide the air and fuel down the crank better, but what im trying to get at is, at the moment the red paste in your engs is off and blocking the end of the crankshaft. Well removing it will not allow that to happen, just looking at it as preventative damage. Stop it from happening all together.

Ad two more to that!

There were two seperate incidents at my local track and both were also JP's.

I wonder if the factory installed silicone "ramps" in the Rex and Top engines will do the same thing.
