I'm in the middle of repairing damage from the chain coming off of this from the previous owner. (I learned this is somewhat common on these for various reasons.)
What are you guys using to either help keep the chain correct and on the sprocket or guarding your engine in the case that it comes off / breaks?
Is there an upgraded guard that can bolt around the sprocket in replacement of the currently broken OEM alluminum?

I recently purchased a raptor 80 for my grandson for christmas. I am trying to make sure it is running properly. i have rebuilt the carb and adjusted the carb idle then the mixture to middle of where it runs rough and it runs great for about a min or 2. then it stalls out. I can usually choke it and it will start so i feel it is lacking fuel. the fuel shutoff valve has been changed and i checked it for good fuel flow. any ideas of what to check next. I am planning to vfy fuel float height tomorrow. I visually checked it by turning carb upside down when i had it apart and it looked level. any ideas are appreciated.
Thanks.

I picked up this ATV that had no spark. The previous owner said he was driving it and it died and would not start. He discovered it had no spark. He replaced the CDI and the coil with no luck. He got tired of it and I bought it. I replaced the stater and now it has strong spark. Now, it starts for a second or two then dies. It will not stay running. I have checked the timing and it is spot on. The valves are adjusted correctly. I see no warn issues with the cam. I put the original CDI and coil back on it. Same problem exists. Compression is at 65 psi (has decompression mechanism),
I took off the muffler in case the issue was clogged pipes. No change. I replaced the spark plug. No change. The carb was an aftermarket so I put a Niche carb on with no change. I bypassed the fuel pump and that did nothing to solve the problem.
I don't know if this is a carb issue or an ignition issue. I am looking around locally for an OEM carb to try out but not sure that will fix the problem.
Can anyone help me solve this problem. I am running out of ideas.
Thank you for your time

I got a 2005 350 Raptor Special Edition and I'm dealing with a no start issue; the weirdest thing is when I'm cranking it fires and slows down showing signs of pre firing, smoke shoots out the carburetor every time it sparks. every electrical part (CDI, Rectifier, Stator, Coil) has been swapped out from previous owner, the top end of the engines all new and I cleaned the carb out, anyone got any ideas or similar problems, also is it possible to have a bad spark timing
