5000 this will make someone a killer drag bike at a awesome price.

All of the cp cylinders have different deck height per stroke. Servals are no different. At this time the 54 and 58 are available and both have different deck heights. Calvin usually makes it even easier on us by posting up the blueprints so we can get it perfect.

Here is a copy of the port layout Calvin gives us. Port layout for CPI-S6858P_Serval_Cub.pdf

TTT

The operating range of these or any other cylinders are not soley reliant on durations. Something I was once totally hung up on myself. It does not take a high port timing to get a motor to rev or make peak power at a higher rpm. With triple transfers and triple exhaust it takes less port time to get a motor to rev. Tradition has it most stock non tripple ported cylinders will rev better with a high port timing 200+ but I have found after many discussions with Calvin and many different port layouts that high ports are not always better reving ports. Yes on my dyno this motor peaked a little lower than I expected it to but with more load on the motor I'm sure it will peak higher. The operating range with this cylinder is very broad and the motor will make power over 10k rpm. Which is where I feel the pc will fall short. We always build a motor to suit and pipe to the motor. I think nate told me his made power over 11k but still came on at 3500-4500 which is basically off idle for a two stroke. I will gladly test a set of pc if someone has some.

I understand how a 2 stroke pipe works, not claiming to be an expert pipe builder but it is a important part of building a motor, no need to explain. The characteristics of a PC or any other low-mid pipe in there inherit nature of design IMO, will never be the pipe of choice for this motor. If you think that you can make another 10 peak hp out of this cylinder by using a low-mid setup then i guess I fail to understand your logic. You say your looking a motor that is basically a tractor but you come back with "I know the motor can make 90+ hp with pro circuits, mid tension reeds, and 30mm carbs"??? I hope that there is better setup and i guess im a little confused at what you are looking for. You said that you did it with a 7mm cub, lets see that graph and let me compare it to one our cubs. I honestly dont want to compare your dyno graph to the serval that we built because its comparing to different breeds to each other which would not be fair for you. I know that you think your logic is the best possible setup, and it may be, but until you can test it lets lets leave it at that, "theory". I hope this continues to grow as a discussion and not an argument because i do not want to steer away from the good of the thread. Have you ever ridden a big motor. I can assure you that i can show you a bigger motor that will make more power from top to bottom than any stock stroke stock cylinder that you have ridden. Maybe that would be something for you to consider. The problem with a motor like that is who wants 120+ hp in the tight trails, maybe you, but for the most it would be too much.

Well only testing will see. I still agree that there is power left on the table as i know that i will be able to improve on this setup. I will however agree to disagree that the pc will ever be a pipe of choice on this motor as i just do not see that small of a pipe ever being able to keep up with a cylinder that flows as well as this one does. I hope that I am proven wrong as my ultimate goal is to improve the sport and offer the best combination available. I will try and get it back on the dyno in the near future for some more test. If your interested in getting a setup together shoot me a pm and we will set you up.

Testing is the key here and we want to test more setups unfortunately we do not have the time to do all setups. You have to keep in mind that this is not a stock cylinder this is a triple transfer triple exhaust big intake motor with low port timings. This is a new school of thought making a low-mid motor so testing is what is going to have to happen. Nate tested with many different pipes and many different timing/dome combos and even stock carbs and stock reeds. In the pipe world on every motor that we have ever tested the t5 is so far from a top end pipe it isnt even funny when compared to a true top end pipe like the shearer. I was actually surprised that Nate said that the motor did not come on as soon with them as they did a shearer as well. I do agree that more compression will make for broader tq curve but the low timing does not surprise me with this port layout. Comparing two bikes together and attributiing the ability of one to "come out of the hole faster" to the port timings is far fetched. There are a million variables completely unrelated to port timings that this could be attributed to, like bike weight, suspension setup, clutching is a big one, rider weight, rider ability, tires would be huge one... Now im not saying that a higher port timing can make more low end power, nor that a lower port timing motor cant rev because I have been proved wrong and tested this myself many times. Post some dyno graphs of your low end motors so we can see. I will say that I have tested and seen a lot of nicely done port jobs on stock cylinders setup for dune riding, and this is as nice smooth of power as I have rode.

Yes the cub/serval dome will fit a stock style cool head. Were really able to pass on the savings as a package deal. On top of the fact that there are a million combinations of packages that we could do and never suit everyone. PM me and ill set you up with exactly what you need. Andy

Ok guys we got a few to many bikes in the shed so were dump a few to make room for more projects. The bike started as a 87 j arm Banshee Here is a list of mods 421 Cheetah w/ powervalves polished cylinders Hotrods 4mm longrod crank w/ maxload 1-5 ND Duneable Transmission 40mm Lectrons on Alky UPP Intakes VForce 3 Reeds 12" K&N Filters with Outerwears Billet Clutch Basket DD Lockout with DD Lockout Cover Cascade Billet Stator Cover Lonestar +10 Billet Swingarm JJ&A Drag Axle Stellar Performance +2.5" Forward Drag J Arms Fast Fibers Front and rear Hood with custom Paint Drag Bars Nology Pro fire coil Pingel Tether Kill Marvin Shaw Comps all the way around RDZ 2 out the left drag pipes Front Skat Smoothies on .125 Douglas Wheels Rear tires will have a choice of some 22x11x8 10 paddle SLS or some 22x11x8 pro wedge II we were running a 22x11x8 14 paddle stg extreme on this bike Im sure there is more that i am missing. Pictures really dont do it justice. Any questions just pm me or call 918-273-1700 just ask for me. Locogato rode this bike at the hq ride so he can also vouch for the way it performs. Sorry for the dirty pictures its all i could come up with. Asking $5500 Andy M&M ATV 918-273-1700

A stock style head will work. Standard cub domes will work.

Ok guys after huge demand we decided to do a blowout Serval Cub sale! We are going to do 2 kits one with a cool head one with out.

LOL 1/4" to 3/4" of an inch i think you may have left out a 0 there.

If that was oem bearing thats most likely your problem. The crank needs to be welded and a good bearing put on it. Andy M&M ATV

All of the manufacturers cranks can break i can show you about every type of failure on all of the major manufacturers cranks. With that said wiesco, i would stay away from, because the center axle is not welded and you cannot get to it to weld it once the crank is assembled and it will let the crank become out of phase. Hotrods have been fairly good cranks the rods have good yield but lower tensile than some, but the welds are junk and MUST be re welded. I have seen many billet cranks come apart on the snout of the crank and typically use a hotrod rod. These cranks are taiwan not chinese. They are assembled here in the US by I think this bansheehp guy. Again the welds are not even close to sufficient so we order them not welded. We pin every crank that we order and use a different outer pto side bearing and wrist pin bearing. The rods have a much higher tensile than hotrod but a lower yield % so they will not deflect and return as well as a hotrod but will not bend as easy. The rods are as good as anything out there right now but we are in the process of improving this as well. We have broke or had customers break every brand of crank out there but as long as the motor is properly tuned and the cranks are setup properly they all can last very well. Andy M&M ATV

Wow what a trip! We couldn't have asked for better weather. That has got to have been the most banshees I have seen on the dunes since pre 450 days 10 years ago lol! I wanted to thank Tyler for help putting this trip together. Thanks for all the support that everybody has given us the dinner was just a small token of our appreciation. It was really good meeting everybody, I am terrible with names and since everybody seems to have 2 lol (real name and screen name) it makes it harder to know who is who. Everything seem to run real well some really good running bikes this trip. Our dmx didn't like the pulse pump hose being unhooked very much lol so it blew up, but other than that everything ran awesome. Thanks to Jerry and Justin for bringing the heat on there bikes and representing us very well. I have to give a huge thanks to Tim at Stellar for riding the shit out of my bikes and getting me parts to make it all come together, hope you enjoyed yourself brother. Most importantly I need to really thank Justin, my right hand man, if it wasn't for all the long nights and weekends it would have came together for us man!

We will have them all done planning on bringing 8 bikes if all goes well.
