It sounds serious, cam chain tensioner or conrod bearings, get it looked at fast before it causes more damage.

The mpem has they key codes stored it it, do you have a key that came with the mpem?

It looks like your compression is too low (worn rings from dusted motor) Push starting spins the motor faster than kick starting and when hot the rings expand just enough to seal off. Before kicking a cold motor try putting in a squirt or two of engine oil in the plug hole to see if there is a difference.

if you have one of the kill cords that is round and it snaps onto a round button that has a silver dot in the center that when the kill lanyard is snapped into place makes a connection to the silver part inside of the kill lanyard itself. most the time its because it is still verifying that it is the right key. they are programed to match you CDI box/ignition module of your ski. this prevents theft. if you clean both the key and the button the key connects to with some rubbing alcohol to insure a good clean connection will most likely solve the problem. when you put the key on the ski you should hear a beep then wait 5 to 10 seconds before hitting the start stop button . that gives the ski time to recognize the key is in fact the correct key to the ski.. hope this helps

You should purchase a voltage regulator. If the headlights are the original wattage, your issue is most likely a faulty voltage regulator. You can find them on amazon really easily and all you have to do is remove the front plastics/ fairings unscrew the old one, and screw the new one in. Then attack the cable and you should be good to go!. Really really really simple and most likely will solve the issue and maybe even make your engine run a little better.

On the side of the engine casing you will see a black rubber/plastic cap. Unscrew it. you will notice it has a dip stick attached to it with two markings. The bottom line is the minimum oil level and the top is the maximum oil level. Good oil level should be some ware in between. Run the engine for a about 30 seconds while it is on the center stand on level ground so that the engine is horizontal to the ground.Open the dip stick cap only after the engine cools for about 10 minutes. Wipe the dip stick with a dry cloth and then dip it into the engine with out screwing it shut. Pull it out and see what is the oil level indicated. Breaking in involves riding the bike under 40Km/hour the first 750 Kms. Also remember to vary your speed as often as possible and shift gears too as often as possible. Do not ride at a constant speed for long. Change the engine oil after 750Km's the first time after that every 2500km or 5000km according the to the grade and brand of oil you are using.Do not rev: the engine a lot ( or go at high speeds in excess of 50Kms/hour ) for the first 2500kms.

where is the horn mechanism inside a w900 kenworth

jetting would be 45 pilot and 165 main jet but this changes dramatically depending what altitude you ride at - you might want to check your fuel air screw it should be 1.5 to 2.5 turns out from fully closed
If you are running to lean you will get a very big clue when you ride it the bike will backfire, pop and crackle every time you come off the throttle.
Also might be worth mentioning your header pipe on any YZ four stroke will always glow red especially when bike is idling. These YZ's are deigned for only one thing go hard and fast which gives them heaps of air flow for cooling but if you notice your header red when you pull over or leave it idling minute or two then thats pretty normal
Cheers mate let me know if you want more info etc... Good Luck!

The O ring needs to be replaced.

air filter , idle needs tweeking ,

If this is a ZF Meritor Trans and you have driven through Salt
remove the tailer cords from their plugs and clean out the corrosion

the corrosion causes the Tans ECU to go nuts.


if it is an Eaton unit it most likely needs a new XY shifter
