I go the third week of august every year. We have reservations at the koa. We have always had good luck with the weather in August.

That is definitely not good on a brand new motor. Did you know that the "stock" curve in the dyna is not the same as the oem cdi's curve? If I read that right you added 3 degrees to the "stock" curve in the dyna. That would be 3 degrees at 3,600 rpm's, almost 4 degrees at 6,000 rpm's, 5 degrees at 7,000 rpm's, a little over 6 degrees at 9,000 rpm's and 7 degrees advanced at 10,000 rpms. I don't know that that would have anything to do with a cold sieze, but you may want to change the timing around in the dyna if you plan on keeping it and running pump gas. I can post up a pic of the stock curve drawn on the dyna sheet if you want.

I just put a +6 on my bike with the serval. I was running a +4 with my previous setup. I am going riding next weekend. I will see how big of a difference the 2 inches makes. Glamis will be a little different than where we ride up here in Oregon. We generally run them a little longer for the tree shots.

I haven't had mine in the sand yet, but I did have it on the dyno and I did not have any slipping. As Snop said, it's the fast heavy duty clutch with 6 heavy springs. The lever is a little stiff but I have one of the easy pull levers with the bearing in it. I do have a slingshot incase this doesn't hold up at the dunes next weekend. I just don't want to add the extra weight to the tranny if I don't have to.

I got my battery and rectifier from trailtech. It came with a wiring diagram too.

I have a +4 that's still on my bike but coming off soon. It is black and it is the roundhouse style carrier. The carrier is not for sale. I have another guy that I sent some pictures to this weekend and I am just waiting for a reply. If he does not want it I will let you know if you are interested. It is in decent shape, not perfect. The coating came off in a couple spots and there is a little rust starting.

I have a +4 roundhouse on my bike right now that will be coming off. I'm waiting for a call back from stellar to find out if I can get a +6 before my trip coming up in a few weeks. It is black and in decent shape, there is a couple chips in the paint/ powder. I believe it is an alba swingarm. I'm keeping the carrier. I will probably let it go for $250. Let me know if you are interested.

I'm 6'4" 220 and my bike does just fine. With the stock setup it would want to two wheel in the corners. The +2+1's made it way more stable. It was a huge difference. Depending on where and how you ride will probably determine how wide you want to go. The +2 work well for most.

No, a stock clutch is not going to handle this. Bare minimum you will want a billet basket and a heavy duty clutch kit with heavy springs. I haven't got it in the sand yet but just riding it around and doing the break in, this has power everywhere. You wont regret it

Here's a few pics. +2 +1's with YFZ 450 shocks. The ride is way better than factory and the shocks are fully adjustable. I picked up the shocks for $165 and they were already powder coated that color. You can't go wrong with Tim's stuff. I just ordered a +4 swinger for my wife's bike today. Got rid of those ugly factory lights.

It wouldn't let me edit my post. The cpi's and shearer's are very close in comparison until they get to the top. If you take that 3-4 hp gain that the shearer's had and apply it to the cpi's curve in my graph it would put the cpi's right about where the pro circuit's already are. The shearer's in Nate's graph gained nothing down low with bigger carbs/ reeds. There was not a major gain in the top end from the stock carbs on this graph infact they pulled the same peak hp.

Andy, if you look at Nate's graph they red line is the shearer's with stock carbs and stock reeds. The green line is the shearer's with 38's and v-force. There is only a 3-4 hp difference between the two setup between 7700 rpm and 9500 rpm. The bottom is identical. I think the graph is posted on page 6 or 7 here. I got this info from atvdragracers from his post.

I guess we will never know until one person puts all of these same setups on one bike, on the same dyno and runs all of them to the best potential. I'm completely happy with my bike the way it is right now. If somebody can run all these tests and prove to me that buying all new carbs, intakes, reeds and pipes is going to make a substantial difference I will throw in the towel and pony up. Until then, the pro circuit's came out better in our testing.

Windy- Here is the link to Andy from M&M's first dyno run of the serval. Look at his curve as it is closer to my unloaded curve. His also peaks at 80 with cpi's and 34 pj's. It peaks at 8,456 rpm. The pro circuits peaked at a higher rpm than that, a little over 9,000. Andy, I'm not bashing what you did here. I appreciate the amount of work you have done with calvin on these. I am mearly trying to show that we have three different dyno's that show completely different peak numbers with different but similar setups. http://bansheehq.com/forums/index.php?showtopic=134580&st=0 Windy- The reason I refered to Nate's sheet was because even with the stock carbs and shearer's the motor peaked the same as with the bigger carbs (86.6 hp). There was just a dip in power (about 3-4 hp between 7,700 to 9,500) between the two different carbs and reeds. I was trying to point out that if you added 3 or even 4 hp to the curve for the cpi's on my graph in that same rpm range you would just hit where the pro circuit's already were. With looking at these three charts it as plain as day that you can not say all these dyno's are with in one horse power. With nearly the same setup Nate's dyno show's 6 more hp than Andy's, and a huge difference in the peak rpm range. The only difference that we know of was the 34 pj's on Andy's and the 38's on Nate's. Nate also said they tried some different domes, I can't find what size dome's or compression it was running. Windy- I appreciate that we have been able to keep this a discussion and not a bashing thread. I know that you and Snop have butted heads in the past over the pro circuits and small carb setups. This is my bike not one of his. Snop has definitely been a big part of helping me get it setup and like I said before I was skeptical at first of the pro circuits. After seeing what it does and seeing how it blew the cpi's away from the bottom to over 9,000 rpms on this particular dyno I can't see changing anything.

I will start this off by saying Snope is a good friend of mine and I was skeptical about the pro circuits my self. After we made the pulls and I saw the difference I was shocked. I was half expecting to be looking for some shearer's or cpi's when we got done. After the testing I am keeping what I have. I know we were not able to test the bigger carbs with the cpi's, but I know that Nate McCoy did. If you go over to atvdragracers.com and check out the serval thread in the two stroke tech header, go to the second page and look at that graph. You will see that the red line which is shearer's with stock carbs and reed cages is the same on bottom as the cpi's and shearer's with bigger carbs and v-force 3's (which are the upper two lines). The red line falls off a little on mid/ top but peaks the same hp number. They picked up about 5 hp by putting bigger carbs on at the top of the mid range. Now if you look at my graph with the cpi's it dose not fall as much in the mid range as with stockers. The Pro Circuit's are 4-6 hp more all the way through and they start pulling before the cpi's. It is just speculation, but I don't think that you will pass the pro circuits until the shearer's or cpi's hit around 9,000 rpm. It's going to be an argument unitl somebody has the time and money to put all of these combo's on the same dyno. I am extremely happy with the setup and after looking at Nate's graph with the compairson of the stocker's verse the bigger carb's I feel even better. There is more than one way to skin a cat! This cat got skinned with 28's and pro circuits! (Pun intended) okbeast- This was not a waste of money. I had a 4mil stock cylinder in this bike to begin with. I know it could have been ported more and I could have sqeezed more out of it. I was running 175 psi of compression and running race gas. I know have a serval that is 20-25 more hp and on pump gas. The stock cylinders were probably more of a trail port and Snope was beating me with his ported 350, his bike runs hard. This serval will pay for itself in two years with the cheaper fuel. How can I go wrong. A waste of money would be spending another $1200 to buy new bigger carbs reeds and bigger intakes along with a new set of shearer's or cpi's to get a little more on top.

Here is the "unloaded" graph with the RPM on the bottom instead of the MPH. All three runs are the Pro Circuits.

Builder, I know you weren't knocking my bike. I understand why people reacted the way they did to the graph, we were expecting it. No hard feelings here. I'm glad you are going to have your bike down there so we can line up and see how they compare. Don't worry I am nowhere near 150. I'm 6'4'' and about 220. I'm just excited to get this thing in the sand where I can get some traction.

Builder, I see what you are saying. I understand that the numbers from this dyno may be misleading to some. I will most definitely be at the HQ ride in a couple weeks. I am looking forward to having our two bikes there for a real world comparison. We knew the numbers were going to come out this way because of the dyno and that's why we tested the different pipes for comparison. How are you setting your bike up?

The only curve that is in mph is the unloaded one, which is probably the one you would want to overlay. I will see if we can get that changed and emailed to us. It wont be quickly though. Nate McCoy tested stock carbs and reed cages with shearer's, cpi's and t5's. he said the t5's failed and the cpi's and shearer's were around 80hp and 50ft lbs. I get what you are saying about testing the bigger carbs with the setup we had but we only had about 3 hours to get the testing done and I dont have a set of 35's larger intakes and v-force reeds. Kind of the same thing when you didn't have a set of pro circuits to try. We tested what we had. Going by what Nate found with the stock carbs and reed cages we pretty much tested that with the 28's and stock reed cages and cpi's yesterday and the pro circuits came out on top. I am not saying this is the best setup for everybody. The bigger carbs my pull a little more rpm and hp up top, but that's not what I was after. I can't justify $150 for bigger intakes, $300 for bigger carbs, $200 for v-force 3's and $600 for a set of cpi's or shearer's. I am going to run what I had. I am very happy with the outcome and I am really looking forward to pulling up next to people and surprising them with my pro circuits. The intakes were cleaned up a little, not timing changes or anything.

Here's the setup 4mil Serval with cleanup 22 cc domes with .054 squish 156 psi 92 octane pump fuel stock reed cages/intakes with boysen power reeds TM 28mm Mikuni's p4 175 nozzle air screw 1.5 turns Pilot- 25 Needle 5L1 1st clip Main- 460 Pod filters Pro Circuits with 296 silencers BR8ES plugs at .024 Here's the timing curve we had the best results with. It's basically curve 3 modded a little. If you have a timing plate I wouls say put it at +4 and call it good.

Now remember this dyno is going to read lower as it has the eddy current brake on it. That being said we tested the pro circuits with 296 forest silencers and 304 factory sound silencers (the outcome may shock you). We also tested the CPI's and Trinity's. We wanted to test these all on the same dyno so there would be no confusion or trying to compare numbers from different dyno's. This dyno is known the be very conservative. Here is the chart with the 4 setups that are listed above. We also tried some different curves on the dyna ignition and got the jetting sqaured away. I understand the Pro Circuits may not pull to the moon, but I know for a fact that is not where I want my power. I'm not constantly running it at the redline. It's not a drag bike. (Light Blue) Run 19 Pro Circuits 296 (Forest Approved!!) (Red) Run 23 Pro Circuits 304 (Factory Sound) (Green) Run 26 CPI (Dark Blue) Run 28 Trinity Stage IV Just to clarify THE PRO CIRCUITS WITH 296 SILENCERS ARE THE LINES ON THE TOP OF THE GRAPH!!!!! HP and Torque for all four setups. Same curves without torque and the writing out of the way. Pro Circuits by them selves I will get a picture up of the timing curves and give you guys all of the jetting and setup specifics in a few minutes. While I'm doing that go order some Pro Circuits for your Serval

Yes the throttle response is good, and its even better since I dropped the pilot one size. If you are in 3rd and drop near idle and then peg the throttle it comes right bike. The higher the gear the longer it takes to come back into the power band. Most of those pulls up the driveway I was rolling in 4th or 5th and easing into about 1/2 throttle.

Alright, here is the helmet cam video. Like I said it's nothing spectalcular as I was finishing break in.

I have a helmet cam video of me riding it at a friends house. The video is nothing spectacular as I was finishing up the break in. I wasn't running it all out. I got the video compressed last night but the uploader on Vimeo was't working very fast and it said it had about 3 hours to go and was only at 8% after about 15 minutes. I shut it down and went to bed. I will get the video uploaded this afternoon and post it up. I will get some video of the dyno pulls if the guys at the shop don't mind.

The bike will be strapped to the dyno on Sunday! As soon as I get the sheets I will post up the results.
