Well I think I will start a thread on my X18 starting from the day I pulled it out of the crate. Uncrating was fairly easy and straight foreward. Now the fun begins. First I gave the bike a thourough assesment of assembled "quality" and like so many of you comment, it was pathetic at best !
Right off the bat i'm finding cross threaded body mount screws, plastic components that were barely "snug" .
Next moving on to getting it started. I know many of you suggested swapping the oil, but for my initial quick break IMO. the std oil is fine. I'll put a few easy hrs on the engine, then dump the OEM stuff . Initially my X18 would start no problem but would not idle. So after searching I found the idle screw, and after about 2 turns, now we're good I have an idle. My engine has a slight surge to the idle, and i'm thinking the carb is jetted "EPA" lean, so I might open the carb up and see what the jets look like. Right now the first step is to put the engine through a few "heat cycles" I believe heat cycling the engine tempers the internal components for longer life. People will argue this comment, but i've been doing this for many years with excellent engine relibility following new or rebuilt running. Here's a few pics for those of you that didn't follow my "pulled trigger" thread;

Took it for a ride after a quick once over, holy crap the dam chain was SO tight i felt resistance pushing the bike around (I thought the rear brake was dragging. I will post up a correct "how to " for adjusting your chain. FYI adjusting your chain snug with the bike on the side stand is NOT the correct tension, and it will be tight and beats the crap out of the wheel bearings ! I will explain why later.
So for my initial ride, the engine was tight and revs were a little slow, but all to be expected of a new engine. The gearbox shifter good, and should only get better over time again as things break in. The clutch adjustment was horrible, and the bike would jump as I put the bike in 1st gear. I realized there was about 1/2" of clutch lever free play. So now I have about 1/8" and the clutch action is way better. I personally already don't like all the "mini" hand controls, and the "feel" of the bars and controls is VERY important, so i'm thinking full size hand controls. I am even thinking of fabricating slightly longer handlebars if the cables will allow. Power was nice, and fun. The biggest problem right now is the lack of steering sweep. Thats my #1 priority as the bike just doesn't like to corner sharp. Those steering stop pins relocated is the FIRST necessary mod. Lastly the brakes. The front brake is "ok", the rear absolutely sucks ! I'm not sure if the brake pads need to be "burned" in and will get better, or if the currnet braking performance is what I will have from now on. If the later is the case, I will absolutely need better braking ! All in all it was a blast to beat around my work !
What do you guys want me to do as far as each mod ? Should I keep the mods within this single topic, or should I start a new thread specific to whatever the mod is I am doing ? It might be quicker for a member to search for a specific mod if it carries it's own topic... just some thoughts. Last comment as I start moving towards mods, please be patient as I am working huge overtime at my work, and i'm going to night school for CAD, so go easy on me if it seems like a mod is in limbo ! I will also make sure I take tons of pics along the whole build !
I bought acomplete front and rear set of brakes off a '96 KX80, so my first mod is to retrofit the KX80's brakes into my X18. The brakes are probably going to be a tight fit, but WELL worth the effort (or should I say LACK of braking effort) LOL

You won't get aany complaints out of me.After all i started a bike build thread and thought it was only gonna take me 3 weeks. It turned into 2yrs and i forgot a had the bike.LOL So i won't be rushing you at all.LOL
Started tearing off the bodywork. What a friggin PIA setup with the OEM 6mm phillips pan and nyloc nuts !!! I am going to use 6mm stainless pan screws and 6mm "U" nuts for ease of bodywork removal. I also made a good call to purchase a Mikuni VM20 carb, as the OEM carb has a lot of EPA friendly smog crap that need to get yanked. Even the exhaust has a "clean air" injection system. Lastly the swingarm chain adjuster end caps need updating. I also plan on "indexing" the swingarm for ease of future chain adjustments keeping the rear wheel aligned. Here's a few more pics :
aThey put a smog valve on it. rip that crap off, and put a small plate over it. did that on my ZX1 110cc dirt bike. All it does is dump dirty air back in your engine. I took that tuned air system off and a new 26mm Mikuni carb, which is over kill. Also put on a oil cooler and modded an X12 HP Side Exhaust w/ is 4 lbs lighter than the stock muffler.
I had to take the body off two weeks after I got it. Them nuts under the tank and the body panel is total Crap.

Yea, I pulled off the muffler to gain easier access to the seat pan nuts, and I noticed the OEM muffler is heavy ! Modding the muffler is on my list as well.
For the clip ons i use X1 X2 stock clip on bars. They are way better than stock ones that come on the 4 stroke bikes. With the x1 x2 clip ons you can adjust how far in or out you want the bars,in terms of length. Plus the move the bars forward by an 1/2'' maybe a little more.I had to get rid of the crappy ones that come on the X18/X15's anytime under heavy braking the bars would move on me.This would **** me of real bad and no matter how much i tightened them. They still would move i think it got to the point the bars were bending under the pressure. Plus with the x1/x2 setup you can swap out and use different bars.I'm eventually gonna put on my carbon fiber clip on bars if i ever find them.LOL Oh yeah those little pegs that limit the steering sweep.Just take them off, those were the first thing i took off my bike.

Thanks ! I source out a set of those early X clip ons !
If you keep the stock exhaust can, open it up and remove the hunk of crap that resides there. It will take some work to get the inner can out, however; it will be worth it. You engine will thank you.
Technically it's not an "EGR" system, but more so all's it is, is a vaccume operated pump that pumps fresh outside air in and feeds that air into the exhaust.
I am also NOT in the least impressed with the chicken scratch welds ! For my safety's sake my frame is getting stripped, media blasted, then i'm going over all the welds with a TIG torch and fuse the welds in better. The a quick powdercoat (i'm thinking matte black for a custom look) and we will be ready for re-assembly !

Look up a thread by unproracer..he did a mod to his frame that made it alot stronger by adding tubes from the trellis continuing it to the vertical tubes that attach to the rear swingarm.....
That fresh air systerm was installed on X-22's way before the new models...On my X-22's I used that system to my advantage by using it to powersuck the built up pressure and heat from the rear crankcase vent hose aswell as my homemade head breather mod that runs off the front valvecover cap..i hooked then into a Tee and into that black cylindrical looking tube with 5/16" hose nipple.....It works the same way as a vaccuum balance system for drag cars when hooked up right..........
To enhance scavenging all you need to do is wrap the pipe with exhaust wrap.....the superheated gasses escape faster too..........
I knew it was gonna be a short matter of time before you were gonna rebuild it to your liking...lol.......Have fun

Odd thing about the "fresh air system" Out of curiosity I dissasembled the unit and to my surprise it was not a "vacume" pump, but a one-way metal reed type valve (like a 2 stroke intake ). I'm not understanding how the fresh air gets up into the exhaust, unless it's just the backpressure pulses that are strong enough to draw fresh air through the reeds and into the exhaust ?
That reed air valve lets air into the exhaust, to make a cleaner burn. My ZX1 extreme dirt bike had something similar, but it was broke on arrival. I contacted MPR, even drew them a picture and they tried to act like they didn't know what I was talking about. There under new managment Now.
I had to Sick my credit card company on them w/ my first Cag. I had to sign a release that I would not sue them bla, bla, bla, but I got my parts. They sent me an A2 seat/tank, for my A1.
I PMed you. At PB Parts, scroll down the main page and click on the bike you want parts for X1 or 2, X18, what ever.
I fixed the OEM one and put the other away. Now its on the Lucky 7. The body was broke on my C1 too. I sent Tsun photos of the broken tail, and they sent me a new seat/tank. I fix the old one Bobbed the tail, is in the Avatar photo, the new one is in a box. One thing I learned on these bikes..... As long as you have a replacement part, the old part will not break, its always the part you Do Not have that Breaks,lol,.

Well had a good few days of dissasembly ! These bikes are def not rocket science engineering. There is a lot of improvement to be had by some imagination, finding better parts, and welding..
My first task is some added frame gussets near the backbone angle, and then hopefully source out a shock soon to get the next phase started !
Here's some more " down to the frame" pics:
BTW, can you guys tell me exactly what engine I have based on the pic ? Thanks!
