I got the chance to break my motor in over the weekend. I have the JPX Plus.
I tried several different pipes on it and the one that seemed to work best for me was a Werks 053 pipe with a double bent header from SH.

With this combination I was running the motor right around 190-210 degrees throughout the day. With roughly 3/4 of a gallon on the motor I hitting 10 minute run times with no problem. The longest run I got out of the motor was just a hair over 14 minutes.

I must say so very I am extremely impressed with this motor. The only thing I want to know now is how many gallons I can get out of it!

I dont now that it matters but I did take the carb apart and seal the needles and carb pinch bolt. I checked the front and rear of the block but saw no leaks so I didnt do anything to seal the block itself.

i would be impressed if the run time's kept up with that....but knowing these motor's the run time will come down as the motor break's in...you wont feel full potential till over a gallon.

NeoNot, thanks for the review. At 3/4 of a gallon, how is the pinch on the engine?

Please keep us informed.

Picco's hold mechanical pinch for OVER 2 gallon's....Dont be surprised to feel it even longer then that.

Picco's have THE HARDEST cranks in the industry...ask any modder and they will tell you the Picco cranks Eat Bits/file's alive they are so hard.....the Only thing i would HIGHLY stress is a New rod after break in....with the crazy mechanical pinch the rod tends to take a beating during break in and the initial running of the motor....Get a rod to be safe.

Runtimes on these jammin's are affected in a huge part by setup..... I get fantastic runtimes with these engines with all the power anyone would ever ask for...IMO these are very underrated engines

What pipe would you suggest? I have heard the 086 pipe works well with this engine.

It is every bit as tight as it was before I started breaking the motor in.

As fas as the con rod goes. I have seen no ill effects to it at this time. I have been using a heat gun to get the motor up to 200 *F before firing the motor so this may help a little as well.

I still think I might be able to squeeze just a little more run time out of it. I am still a little rich on both the low and high side. It isnt a lot but there is still some room for adjustment.

I am not sure what everyone else likes in pipes but I tried several out last weekend looking for changes in power, heat and run time. I tuned the motor each time I ran with a new pipe and none of the pipes gave me better run times than the Werks 053.

I also tested an OFNA 063, JP2, JP3, SH 2060 and an RB Concepts (dont know what number it is).

The 053 seemed to offer the best overall preformance. I had good bottom end with a respectable top end.

I dont know how much of a difference it mades but I also tried four different headers as well. Double bent header from OFNA, double Bent header from SH, short curved and long curved header.

In the end I went with the SH double bent header. It seemed to offer a little more low end punch with a minimal increase in run time for me.

I was getting 11 to 12 on mine, but that was when I some how changed my radio settings and tuned the motor with the barrell only opening to 3/4, but still had a tonne of power and ran 220-230

I noticed the barrell, adjusted it and was way to lean up top 280-290, and had rediculous power, to much really. After bringing run temps and putting the proper tune on it, the run times dropped to 8- 8 1/2.

I am not concerned about overpowering the track and would like to increase runtime and decrease power. A few recommended the 7 mm Picco inserts, has anybody tried these or found something different.

Are there any fast guys going 10 at your track? I don't care about slow people, what are the fast guys doing?

If none of the fast guys are making 10, the track wont take ten and you're not at much of a disadvantage only going 6. If fast guys are going 10, you need to rethink your set-up.



As for the 2013, great mileage pipe with good power. Runs a bit hotter than some others though.
