Title: 400ex WILL NOT start(goes tactactac) Post by: Miami450R on March 05, 2006, 08:04:44 PM my bike was turned off and started like 4 times in a row.....
i went to start it again n it went TAC. and wudnt turn on n the greeen neutral lgiht runed off. it came back on after a little while n went tac agasin once i pressed to start my bike. i charged my battery to full. i put it on. this time the light stays on , but bike jsut continuously goes TACTACTAC when i press the start button. we checked and there IS spark coming from the relay , we tried to put it directly by getting the wire and connecting it to the battery n it STILL wudnt start , btu wouldnt click either.and the neutral lgiht turned off. we then put it back on. n still nothing. now I think that is either the starter , or the relay... anyone had this problem before?? anyone think they know what it might be?? thanks.

Why don't you borrow a friends battery that you know works for half an hour and see if it works??? Title: Re: 400ex WILL NOT start(goes tactactac) Post by: Miami450R on March 05, 2006, 08:13:44 PM it was working perfectly. exccept that last time i went to start it. it chrged till it said full. it starts PUSH starting it. but elecrtic start jsut wont..
Title: Re: 400ex WILL NOT start(goes tactactac) Post by: LakeMaryKid on March 05, 2006, 08:22:40 PM I had this problem with mine before also. I forget, it is either the battery or replace the fuse behind the left rear fender in front of the battery. Im pretty sure it is the battery, have you tested the voltage in the battery yet?
Title: Re: 400ex WILL NOT start(goes tactactac) Post by: Miami450R on March 05, 2006, 08:25:26 PM the fuses are good we testeds the voltage in them.and we also tested the voltage in the battery. the tac tac seems to be coming from the tube(starter) above the back part of the engine.the starter.
My dad is positive it isnt thew batery. but ill try with my neighbors 300ex battery tommorow. Title: Re: 400ex WILL NOT start(goes tactactac) Post by: Yamaha72 on March 05, 2006, 08:36:37 PM Try your neighbors battery tomorrow and if that doesn't work then you might have tore up your starter. Is your motor higher compression than stock???
Title: Re: 400ex WILL NOT start(goes tactactac) Post by: WOODY_450r on March 05, 2006, 08:40:38 PM try too push start it?!?!?! if that dosent work then its not the battery!!
Title: Re: 400ex WILL NOT start(goes tactactac) Post by: Miami450R on March 05, 2006, 08:46:48 PM i can push start it n it starts up right away. lol.
it is a higher compression piston then stock yes. it is a JE high compression piston with 11/1 ratio Title: Re: 400ex WILL NOT start(goes tactactac) Post by: Toomey on March 05, 2006, 08:51:50 PM When our 400 has a low battery (preety often ::)), it does that, just goes nac nac nac, like a baseball card clipped onto a bicycle in the cartoons. It's always been the battery when it clicks. Our neutral light also acts up sometimes. Don't you wish the 400 came with a backup kickstarter, and you could just take off all of the electrical junk.
Title: Re: 400ex WILL NOT start(goes tactactac) Post by: Moose on March 05, 2006, 09:13:10 PM Another thing to try is, with the charger hooked up and at 10 amp output, try to start it after 30 minutes charging time. If it starts, then it's most likely the battery needs replacing. If the battery is not a sealed type, be sure to top off the water level before you charge it.

i connected chrger to battery. pressed start button n it turnd on. the battery is shot. lol. thanks alot for all ur input guys. Problem Solved!! Title: Re: 400ex WILL NOT start(goes tactactac) Post by: Yamaha72 on March 05, 2006, 09:23:16 PM If it is not your battery than the high compression piston culd have messed up the starter... But it sounds like a common battery problem. My sisters Raptor 80 did that when the battery died.
