Sort of, the single carb had a better torque curve down very low, but it wasn't worth the loss it had through the mid range and top end.

Start off by ditching the pipe, going to a good set of twin mid pipes will benefit the most for the bucks spent. After that if your not satisified, make the next step.

You guys have been taken over by 2 into 1 threads?

So much Anger in the HQ now.

I used to have all my pipes cermaic coated so my boots and riding pants didn't melt. My last set of PC's I had done in flat black. They make a fake chrome looking finish in the ceramic coat as well.

Or he got pissed at it, ripped it off, and threw it on the ground. It was laying on the ground, so it did at least fall off. Trinity=Shit

Put it in a box, drop a deuce on it, Write a note "Here is your shit back" and sent it to trinity.

Ahhhhhhh, I see "The Panty Dropper" in your sig pic.

If I had to guess what they would do based on other dyno setups I have ran them on, they would be 1-2 horse under the pc's across the entire board. At peak rpm they would shut off about 500 rpm less than the pc's would.

16 psi import cap.

They are both motor guys that live in bonney lake. They are still in business.

ok, just wanted to make sure you check. That is the reason the ones I build are angled back. Good looking box.

JD, Does that thing clear the rear shock resevoir when the suspension is full compressed?

I am sure it will be slower than anyone else who built the equivelant bike.

As far as that drag race with the pics up top, one major difference I can spot in the picture between the two bikes is the rear tires. One guy is running a lighter wheel/tire combo than the other. 8" rim Buffed haulers can get about 1.5 lengths on the same bike with 10" rim standard casing haulers (at least it looks like the red bike has 10" rimmed paddles on it). Just something I noticed in the pics.

The Problem here is, everybody is looking at peak numbers, and hell even the normal forum members are worried about how they stack up in a drag race. The Serval has port timings that serve as a motor you ride for MORE lower end and midrange hp. I look at those dyno runs for overall curve, torque backup, and ease of using the powerband when I am riding a sand trail, negotiating whoops, corners, and tree shots. If you search back to every post on here were I make a recommendation for carb setup, the only time 28mm carbs is recommended is when someone is asking about how to setup a low-mid motor with a smaller bore. I have recommended Single carbs as well, and still stand behind that for certain applications. I have also recommended twin setups on 30mm, 32mm, 33mm, 35mm, and 38mm setups. As well as larger singles in 35mm, and 38mm. So I completely call bullshit on that accusation. If Shane would have wanted more top end and less acceleration speed from his Serval (which he didn't), we would have went with a 30-32mm carb. We may have been able to put Lectrons on it and maintain most of the bottom end, but the cost investment to do that would have almost cost as much as his serval cylinders did. Wih the pro circuits being the right pipe choice for low-mid, it comes from riding bikes with different motor combination with all sorts of different pipes. Then dyno testing setups with different pipes as well. I dont know how many of you realize this, but I used to ride with a fleet of banshees. Between my family, and my friends there are 13 banshees, 14 if you count the one I owned (that was the third banshee I have owned). There is only one with un-ported cylinders on it. None of them run stock pipes. Every single one of the bikes is built for low-mid hp and torque. A couple of them are chopped cubs that dyno'ed at 96hp on a loaded crank dyno with a water brake. If you want to drag race, stay away from pro circuits. If you want to get a dune port, and recreational ride and drag race your buddies, stay away from the pro circuits. If you want that MX port, or trail port, and you want an ass ripping grunting low end to midrange machine with the 2 stroke top end we love, look at getting pro circuits. I had skeptics even in my camp when we went into dyno this bike, and everyone there who saw what started to transpire, knows what I thought held truth. The laws of two stroke theory completely applied to what we found. We ran every run identical with the fan, temperatures, etc...... Oh, and the bike was re-jetted for each pipe setup we ran as well. Not all the dyno charts out there are on this site. Nate McCoy has charts from shearers, cpi's, t5's, etc...... as well. His RPM numbers lined up with ours. The guy who ran the dyno on our runs had no stake in this motor, he did not build it, he didn't even know about the serval when we took it there. Everything he usually dyno tests is drag bikes (banshees and Raptors).

Indeed!

No comment in the difference in rpm?????????

You didn't say "on this motor" originally, you said "on a serval".

Granted a 10 mill requires more carburetion. However, you don't slap the same thing on a 10 mill Serval that you would run on a 10 mill Cub.

If anything has been learned, forget T5's with any serval, or any low-mid motor setup for that matter.

The runs are so different because one was loaded and one wasn't. There is a huge difference between the two. If you could just gear the bike and run it the same way on the dyno, then they wouldn't make dyno's with a Load cell. The guy who dynoed the bike is one of top dogs for banshee's and raptors on the west coast, his stuff is quick as well. He was really suprised when he saw the PC's beat out those CPI's.

At this point comparison wise it doesn't matter wether the dyno was loaded or not, someone is going to have an excuse for everything until they run them on their own dyno. I was hoping in the months upon months that I had been gone, someone had finally manned up and ran a set of pro circuits against some of the nuthugger pipes and finally got some results. However, I guess everyone is scared to find out the truth. Hell I ran the PC's agains the trinity IV's and the CPI's and everyone still had an excuse for the results, so i guess this is never gonna get figured out. It is too bad, you guys are missing out on some awesome low end and midrange power.
