X18 Performance Parts

Hello guys, I am an engineer and love my new x18. I was wondering what dream performance parts you would want for your x18? I am open to any suggestion because I have looked everywhere and am very unimpressed with what is on offer. Let me know if there is anything you wish you could buy for you x18 and I will design, create and get that part on the market to the best of my ability. I have seen talk of turbochargers, maybe fuel injection, whatever you can come up with i would be interested to hear. Personally I would at least like to see a nice quality intake that makes use of the intake ports that are on the front of the bike for starters. I am sick of seeing bogas exhaust systems which are meerley an annodized version of what is already on bike. I want to see these things rip, i believe they are a great platform for modification, the pit bike guys did it, we can too! Looking forward to hearing lots of responses, I will also try to design and keep costs more than reasonable because I know that pocket bike guys are not in the sport to blow thousands on gear, I bet most of you got into the sport in the first place because It is one of the few forms of motorsport, maybe the only you can get into for well under 1k. Ok guys cant wait to hear what you come up with, remember, I want to hear any suggestion, no matter how crazy!

If your really serious about designing certain performance parts, I would suggest a verity of different camshafts that would be a dirrect fit to these heads, I know that you can get camshafts for these bikes, but no one seems to list them as a dirrect bolt on, if someone could come up different performance kits for certain applications,"certain compression, carbs, valve sizes" something along that line, that would be specifically for the chinese clone four strokes it sure would make tuning these things alot easier. In my opinion to make these bikes a heck of alot more aggresive, compression, carbs, and camshafts are the biggest things you can do to get the most out of them. A good exhaust won't hurt either.

appreciate the reply, I am in the process already of chasing up these parts and trying to weed out of all the hundreds of camms etc that actually fit this bike, hoping to be able to group the parts together so we can buy some sort of performace package. So far I have found that sales reps at these parts places all fall under the one catagory when there job goes beyond looking in a simple parts cataloge.....and that catagory is useless. I have figured that the only way I am going to find what I want to know is to get an engine, which I have on order and personally take it to the vendors and sit the parts on the engine and figure which heads will comply with the engine. I have already spoke yo two brothers racing and they will be able to give me more info by doing this. I am sure that the likes of Takegawa, Kitaco and the rest have parts to fit this motor as it is so widely used. As far as the exhause goes I have one in the works that im nearly finished with on CAD, and it will be a real exhaust, not just a pipe that slips over the existing one! appreciate the input, ill keep you posted on my findings.

If you want to buy a Chinese import engine.............Buy the Lifan or Zonshen 120s.......They use a 52.4mm bore and 55.5mm stroke.....or buy the GPX 125 with a 52.4mm bore x57mm stroke. These are the only imports that are worth sinking any money into. They have much better internals and the heads on the Lifan/Zongshen are the biggest made. 27mm intake and 23mm exhaust valves.........
As for cams Crower G2 is the best for these engines with a nice 26mm carb.

The parts are already out there, all you have to do is look. I have already built and described and posted pictures of a great 114cc buildup and of a monsterous 153cc buildup with big valves. The reason no parts like cams are listed as direct bolt ins on the x18 is because there are many variations of the 110ccc engine. That means that you and I can have the same exact look alike bike with the same specs and they came from the same factory but if mine was built a week later and that factory ran out of engines from one supplier and switched to another then our bikes could take different camshafts. I have even seen this from the same importer on the same shipment to have two different engines. Yes the engines can all be 107cc (called 110s) and some of the parts will interchange but not all.
All you need to do is measure the length of your cam and you will know what fits, it doesn't get any simpler then that and only a psychic could tell you which cam your motor takes as none of the Chinese factories document anything so you could call them with your Vin # and they would only be guessing at what they put in your bike, heck I have even seen several bikes with the same Vin #, the Chinese have no clue.

What parts did you not see? I was quite certain that everything one could want is out there and reasonably priced.
If you really want to set this world afire please invent an affordable fuel injection system that is not $2k like the ones out there right now. Turbocharging would also be awesome, it has been done several times but never with too much success or reliable performance. I would think that someone with an engineering background could tackle such things much better then just a hands on wrench like myself so I hope you are the first to be succesful and I will be one of your customers for the above products. PM me if you are having a hard time locating a part or want to know what kind of cylinder pressures these engines can sustain reliably.

I've got an FMF shorty exhaust that I fitted onto mine. Seemed to give a little more "oomph" to the motor. If you really want to invest in parts, and have the facilities, I'ld suggest replacement bodies. The chinese use cheap plastic, and it cracks right out of the box. If you could make a mold, and use the same polyurethane that the big bike's use (i.e. Suzuki, Honda, Kawi), then that'd be money. The engine is fine, but definitely better parts. High compression pistons, bigger cams ect. Already mentioned.

Ooh, another front brake would be nice, and maybe some 12 inch rims...

Ditch the speedo, and put a tach on it. Maybe make a tach that'll fit in the slot for the speedo, that works with a one cylinder motor.

Ooh, maybe 2 cylinders... (220 anyone?)

Better bodies without lights...

Better handle bars... Put a set of Motrax grips with bar sliders on them...

Frame sliders...

Rear spools...

Better rear shock. Adjustable. Adjustable forks...

Gas tank that isn't a plastic cover. Like a real gas tank...

That's about all I can think of for now.

I'm pretty good at afrofab'ing myself. Sorry to all the haters, but it wasn't meant as a derogitory term. I've made my best stuff that way.

hey bart, you say you posted some pics of a 153cc build up and also a 114cc, where can I see these, do you still have a link to them or something. As far as grinding my own camms, i am not preparred to do that as long as the selection is as huge as it is now, i see no need, just weeding out the parts that do fit on these bikes, so the info about the bikes having different engines was very helpful. I noticed some of the pictures in the advertisements have bikes with a different, flatter looking crank case, obviously a different motor. Thanks for the info bart. My ram air induction system is nearly complete ill try to put a picture up soon.

Thanks alot man, thats great to hear what you guys want. I like the idea of making new plastics, I also have trouble with mine cracking at the bottor behind the front wheel. I have drilled holes and added extra bolts but they still crack. I have a friend who is an expert with plastics, ill see how involved it is to do this. I think because we already have the shape to take a mold from, it shouldnt be a big deal, just the paint will have to be done but the paint on them is not a complex job. The other advantage to producing the body panels is what you suggested about loosing the lights. I could make a set that doesnt accept light if thats what the people want. Im on it first thing tomorrow! I have found a place in lake elsinore that sells a unit which is up gradable depending on how much you want to spend $250-450 which is tacho, speedo, ignition timing, engine temp, exhaust temp and if you want a lap timing divice. This might be pricey to put on a bike that only costs $750 but its there if people want it. As far as the brakes go, I measured some mountain bike brakes up today and the bike seems to accept the standard mount (bolt centers for the calliper) the only problem is that the disk thickness on the x 18 is way thicker than mountainbike disks so maybe I can find a set that have adjustable pad width, but ill keep looking, because of the standard mound there are thousands of brakes on offer, im sure i can find some good ones. I have 6 piston calipers on my mountain bike that are unbelievable. And finally the 220. I would love to make a crank case that accepts the 110cc head.....twice that would be the ultimate. Venom motors sells a 200cc motor which although the cylender is nearly vertical could maybe fir and the bottom end looks very similar to that of what is in the x18.......I wonder how hard it would be to get that in there?? Love the input guys keep it up, its a real help to me and all of you when this stuff gets made. I want to see X18 popping wheelies at 80mph!!!1

Personally I like having lights since alot of our racing happens at night. I suggest making it an option, like something you punch out if you're installing lights, or leave in if you're going light-less.

You might also be able to vacuum-form lexan body panels. That way the entire body would be transparent and you could paint it from the inside (thus protecting your paint-job during a bail) and leave the headlight area unpainted. The only thing about lexan is that it doesn't hold up under long periods of sunlight from what I hear, and would need to be replaced every year or two if the bike were to be stored outside without a cover. But, if you're storing your bike outside with no protection from the elements then you have more to worry about than the farings. (Ruuuuust!)

I like the idea of vacum forming, once set up the panels could be fabricated for substantally cheaper than normal, which, in the event of a crash wouldnt matter, just get some new ones. That is what i want to do with all of this stuff, i want to make the stuff cheap in price, not quality, so that the sport remains fun, not like all other forms of racing where the guy with the most money wins. FUN FOR EVERYONE I SAY

85+ MPH pocket bike, yeah! my 153cc build

Here is the 153cc build up or some of it. The 114cc was a long time ago, you will have to do a search.

We're not allowed to register ours here in Cali, and thus our use of the bike has been downed to complete track bike. Oh well, he isn't legal for the streets for a couple of years anyways.

But yeah, punch out light holes would be the way to go. One mold, 2 different configurations at the consumers request.

Also about the paint. Leave that to the end user. I know, I've looked and looked for parts (cars, bikes anything) already painted and ready to just bolt on, but coming from the manufacturer's point of view: Don't paint. Too much of a hassle. Too many colors to choose, and trying to anticipate what color is the best seller for what month would take more resources than needed to make the dang thing.

Thanks for the link bart, looks very interesting. I went to extreme 4 strokes .com, how does the 114cc kit perform, im assuming thats the one you have fitted to your bike. Do you think it is gonna be alot of work to fit the 133cc i think it is that extreme 4 strokes offer onto the 107cc motor. It says that that kit is for the 124cc motors, do they have a different crank? what would have to be changed to fit the 133 onto a 107? I always thought a 124 was just a 107 with a bigger cylender?

That website is my website. I am a mechanic at a shop here so that is why I work on these bikes everyday, literally.
The 114cc kit is very nice, it is nearly double the stock horsepower when combined with the right cam, head and carb but even just the high compression cylinder kit is a very significant difference.
The 110cc engines (107cc actually) only have a 49.5mm stroke crank so with the 54mm piston that comes out to 114cc but the 125cc engines have a 57mm crank so with the same piston they are 131cc.
There are a lot of differences in the 107cc and 120 and larger engines. There are also many variations of the 120 and 125cc engines. The 120cc engine that I used for the 153cc buildup has almost nothing in common with the 110cc engine as the cases are larger, the crank is way larger the cylinder is longer the stud spacing is different. Essentially there is not one gasket that is the same on that engine but yet they are identical in design and bolt in the same just all the dimensions are different and slightly larger. Actually the cam could be interchanged with some 110s but the head is totally different with larger valves, different cam sprocket and different bolt pattern.

Speaking of parts:

Competition Werkes GP Pegs for a 91-97 CBR1000 will fit with a little shaving.

Any more words on any of these "dream" parts? Updates?

still working on the fairings nocontrol, thanks for checking up on the thread too. I have a love for the look of carbon fiber, but only have limited knowledge on how to build with it. I have spent alot of time lately searching through books and information trying to educate myself on how to form up quality parts. I know that this process is extremely expensive and would not yield any resale value as far as aftermarket fairings go but they would look great. My plastics guy is looking into the best way to produce fairings that are of decent quality and fit and also wont have the cracking problem. The thing that got me hooked on the carbon fiber idea is that i have been toying around with exhaust systems as i used to work for dubach racing making them for mx racing bikes, all of the new aftermarket mx exhaust are comming out with carbon fiber cans, no performance gain but it looks great, so i have been searching for someone that makes the tubing in the right size to use for the can. So as a summary we are all learning about carbon fiber so if anyone has made stuff out of it i would love to hear how it went and listen to any advice that you have on the subject. Just a note too, if you go to your local cragan auto store you can easily find brighter bulbs for the headlight and if you want to open up the hole where the bulb fits through on the fron of the bike you can get excellen bright bulbs to improve the nightime expierience.
thanks guys ill keep you updated.

I was wondering can u specify on upgrading the headlights, it seems I have to replace my headlight because it went out , I'm pretty good in modifying, but can u suggest what kind of bulb / housing of a bulb? perhaps a foglight, modified to fit within the light housing?

Also do you know what kind of voltage is a safe voltage to use?

Thanks, hope to see more of your upcoming upgrades.

x18tuner,r you just making plastics for x18? i got a x15 and need new plastics cause cracks everywhere. i want to get rid of the crappy duel exhaust but plastics have duel tips and i have to run duel exhaust.
