got 7 atvs off CL recently for a good price. one of which is a yamaha warrior. anyone know where the vin is printed on this bike? Haha good place to start as I do not know year or size yet. The former owner says needs exhaust ans and clutch work. he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears. things I see: clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box. I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first. also, battery (looks brand new, what a shame) is dead, 0 volts. Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last). any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like. lol I'm spoiled on my automatic polaris

I have a 2005 Sportsman 500, Instrument cluster will not illuminate, hi/lo beams work though. Any tips or troubleshooting info is greatly appreciated!
Something i have wondered for years is about the firing order of a parallel twin. Yes i am aware of both pistons going the same direction at the same time, but do both cylinders fire at the same time or at different times? Just being curious since i have always wondered.

I have a 2016 Yamaha Kodiak and find myself with a start issue.. I changed the battery so it’s not that.. here’s a video of me trying and then boost starting.. can anyone give me pointers as to a starter motor issue or fuse or wiring or whatever ?.. I find myself without a vehicle with a tow hitch for the 1st time in years so have a dead and stranded ATV to fix !
thanks in advance, suggestions welcome

1987 YFM350FWTB 350 4x4 Big Bear when going uphill will sometimes act like the clutch realeases then re-engauge all at once.
Seems to maybe be little more often if the engine is at about 1/2 throttle instead of at lower rpms.
I have the Factory Service manual and checked the external clutch adjustment screw as ok and the H/L/reverse shifter lever linkage as adjusted correctly. It appears to be maybe a internal (inside the case) clutch issue or ??
This is the type Big Bear that has the manual shift lever on the left front fender and has the manual foot shifter lever with 5 speeds forward.
Can someone tell me how the primary and secondary clutch operates?
I assume one is mechanical and one is centrifugal. (what I'm asking is one clutch for the higher rpms and one for the lower rpms or ???. (the clutch appears to only momentarily release at the higher rpms is why I ask. The cycle has about 3000 miles of low speed through the brush hunting and has been well maintained, oil changed, etc and no deep water or mud useage.
Anyone been into a similar issue with the big Bear ATV????

I live in Minnesota and bought a 2016 CFORCE 500 HO. I am in hope to see if there is anyone in the US that is experiencing this sudden drop off in RPM below 4000 RPM. I have uploaded some videos of my issue on YouTube. I will list three of the four I posted. The fourth can be found on my channel but it is a comparison between my Polaris 570 and my CFORCE 500.
I quit on my first dealer because we just did not mix well together. I brought it to another CFMOTO dealer that just became a CFMOTO dealer in January 2016. They are in a large ranch and agriculture area in a neighboring state that is pretty close to where I live. They have close to every brand available. They are a much larger dealer than the first one I bought the unit from.
I brought the unit three weeks ago to them and they have worked on it a good solid week and have given up on it. I have read reports from owners in Canada that the dealers there were aware of the issue and have had success in fixing the herky jerky drivability issue.
I am picking it up tomorrow and bringing it back home. It has been to the trails of the Black Hills this year and was new in late April. 300 miles on it. It has never changed. Very hard to ride on the trails or when I herd livestock.
Here are the links to my videos.
I can't accept that this is normal operation. Does anyone from CFMOTO China scan these posts?
I need help that CFMOTO USA has not provided.
ok it will start up an run but quits a lot till it gets warm, but has a bad miss an wont idle, I have a brand new Honda carb on it, good gas flow, new plug, but when I let the throttle go below a quarter, it backfires through carb an tail pipe:confused: so it has never had any electrical work or mechanical work done...it just started all the sudden, I'm think it may have ignition coil breaking down, or cdi box going bad...anyone had this trouble before? let me know what you did to fix it. thanks:skeptic:
I bought this old three wheeler that I found in a barn. It looked pretty rough, but I have it running now and functioning.
With the switch set to "run" and the key in the "on" position the electric starter does not work when I push the starter button,
However, if I cross the solenoid it will work and it will start the engine - so I know the starter motor is good and it works.
Now, it gets a little mysterious. When the engine is running, AND the headlight is on high beam, the electric starter will engage when the starter button is pushed.....When its already running! (when the headlight is off or on "low" the starter button does nothing, only when running and in high beam will you hear the starter motor zing when you push the starter button) So, I know the button actually works, but only after the engine is already running and the high beam is on!
So to recap: with the key on, the starter button does nothing. crossing the solenoid will make the starter work, and after the engine is running the starter will work with the button!
Has anyone else had this problem? Can anyone point me in the right direction on solving this one?
