It's not great, it's detonation when there shouldn't be and that stresses the motor. Try cleaning the carb and checking the air filter.

The carb should have o-ring gaskets, they are fine to re use as long as they are not brittle or damaged. The backfire itself will not likely damage anything, but the condition that is causing it could. I would start my checking the carb, air filter and valve adjustment.

backfiring can cause overstreatch of the head bolts and if it is on the down speed then it is usually overfueling and detonation.

      After looking at the wire diagram I saw the blue w/black stripe wire is coming from the neutral and reverse lights looking for ground thru the neutral and reverse switches. If it finds ground, the lights come on. The same wire also comes from the neutral relay looking for ground at the same neutral and reverse switches. So it was easy to trick the relay into thinking the engine is in neutral all the time without having the light on all the time. Just cut the blue w/black wire at the relay and ground it. Easy
      Sorry the pics aren't better




      Now it starts in any gear and indicator lights work as they should.

      So I’ve got a 2000 Honda 400ex absolutely love it!! I’ve had it for about a month, I ride with bruteforce 750’s, outlander 850’s and 1000 sxs’s and I was thinking of getting a trx450r carb and a full hmf exhaust. And probably doing the air box mod too, how much power would this give my 400? Just a little different or a big difference? Cuz if it’s not much of a different I’ll just stick with my dg slip on..... thanks!

      I think my rear brakes are stuck.  Is these parts in the right position?  Any idea how I repair?  I have to give it more gas to go and I can't push it when it's in neutral.

      Good morning!
      I have a 1999 Yamaha Big Bear 350 4X4 and I need to rebuild the carb. I have the dual-cable throttle model and I'm having a terrible time finding the correct kit for it. I'm not opposed to replacing it, but the only ones I'm seeing do not have the dual cable throttle system. Any help would be greatly appreciated.
      Thanks,
      Jay in WI
       
      P.S. I can send pictures if necessary.

      I recently picked up a king quad 700 that doesn't run in the hopes of getting it running by spring. It had been previously taken apart some and a few pieces are missing in the engine, but the frame is complete and in good condition. The motor will need a piston, rings, cylinder, cams, and a few misc parts that are missing. Also the cases will need to be split to remove the pieces of piston that are in the crankcase. The piston blew up at high rpm and did a number on the cylinder so I'm trying to find out if it would be worth rebuilding this motor it buying another engine to swap in. There may be more damage to this engine that I can see so I was wondering how bad the insides of it could be considering it destroyed the piston. I have found a motor for 1200 plus 200 shipping, the only problem is I don't have that much now and I would have to save up a while before being able to afford it. Any suggestions appreciated.
