I have a 1986 Honda FourTrax 250 It is in really good condition the only problem is minor cracks on the plastics. Never really had an issue until now.

Here is what happened I was riding and everything was normal and then I came to a stop and turned off the four wheeler for maybe 5 minuets. Once I was ready to get back to riding I realized that when I turn the key on, the neutral light didn't come on ( I was in neutral ) So the electric start wouldn't work so I kicked it. It started up fine no issues but once I started moving Clank Clank Clank! I stopped it immediately. I think it is the drive shaft because that is where it appears to have the sound and issues. I didn't want to drive it home so we hauled it by chain. It makes the noise in neutral and up, but I don't think it does in reverse.

I hope I can get some help on this it would be much appreciated!

sounds like rear differential needs to be looked at. they wont start at all unless the c.d.i. '' see's '' it in neutral ( dash light ), how you were able to start it without a dash light beats me ?, unless the bulb burnt out ?. it also wont ele start unless the c.d.i. '' see's '' it in neutral.

Thank you for responding! So the bulb isnt burnt out because it was working the 5 minute before I turned it off, but I think kicking it bypasses it and starts maybe, but I dont know. Im gonna crack into the rear and start looking more into it in a couple of days.

yw, make sure its in neutral ?!. to test the bulb the easy way, remove metal plate, right foot rest, behind it, metal plate, under it, two switches, rear two are neutral and reverse, forward switch is oil temp sensor. carefully pull the two rear rubber boots off the switches, the very rear switch is your neutral, turn key on, ground that bullet connector to the engine near by, neutral light should light up ?, if it does ?, and you know its in neutral ?, then the switch is bad, it will not electric start unless the neutral light is lit up on the dash, safety feature to keep you from electric starting it in case its in gear ?.

i highly doubt your gonna do any more damage to it than what is already done ?, as long as your not pulling it for many miles ?, you should be ok. either way, your gonna have to tear the rear end down, may as well start by dropping the rear swing arm, check/inspect the swing arm bearings, u-joint right there, then work your way to the diff, chances are, your pinion gear, pinion gear bearing, ring gear bearings, all the oil seals need to be checked/replaced ?.
