A  lot  more information  is  needed before  anyone can begin to try to help  you .  There  is  a download  of the  service manual  for  the  400ex in the  forum's archives .. Go to  Browse  at the top  then   click  downloads  and   click through  to  the  Honda section  service  manuals.   If  the  motor  turns over ,  check the  spark  plug  for  spark  and  the  carb is getting fuel.  If  it doesn't  turn  over, then  check battery,   fuses  and  neutral switch   for starters..  Then    use the   service  manual  as  a guide  to  check  other components .

      Hi Guys!

      New member and could really use your advice. I would have to believe this has been an issue for others but a search here came up with nothing......? (Probably me not doing search correctly)
       
      I have an 87 Big Bear 350 YFM350FWT
      The OEM Mikuni BTM carb is shot and would rather replace than rebuild.
      It is no longer made and I have had good luck with NICHE carbs so I ordered a #K-CRB-0006 This was what they said was replacement when ordered. This Carb only uses 1 Throttle cable. The Slide is linked so it uses one. (OEM had 2nd cable coming through top to move slide)
       
      Problem is when I ordered a replacement Cable from NICHE (#C-CBL-0061) the Cable wire is a little short, not allowing Throttle to return all the way down to Idle position. I called NICHE and they are at a loss. Haven't gotten back to me after 2+ weeks.
       
      What would you recommend other than a carb rebuild?
      Can I just use 1 of the OEM cables (It is the right length) and snip/disconnect the other that went to top of Carb for Slide?
      Or ??
       
      Thanks in advance for any advice you have!!

      Hello guys, I hope I am not invading your space, but as you can see the current state of my project here it's not but about 50% ATV. I am hoping that some one here can point me to a wiring schematic that I can reference since the "Complete wiring harness" i purchased from Amazon did not include a diagram of any kind.

      The ones that I am finding on line vary greatly but none show the connections for the separate 5 wire connector coming from the motor.

      Can someone tell me where these wires go?
       
      Thanks in advance for all help!

      Hey all!
      I'm on a mission to buy my first UTV soundbar as a gift for my dad(a newbie on ATV). I'm aiming for something that offers great sound quality without breaking the bank – my budget is around $250. Right now, I'm considering options like ecoxgear, kemimoto, and boss.
      Does anyone have experience with these brands or specific models that you'd recommend? Any advice or suggestions would be super appreciated!

      Recently picked up a 1991 Lt230e for repair. Compression is a little low Id say, around 80psi, I also have spark but the spark is odd . When cranking the spark is a constant arc. I’ve got it to sputter but never fully turn on. I believe the spark is my issue, being constant and not detonating at the right time. I’m not sure whether this issue is an electrical fault like some missing ground, a faulty cdi, or a timing issue. Any ideas where I should start?

      I added more fresh gas it sat one day now, it's acting up again. Before cleaning out carburetor it wouldn't idle good and had gas leaks from carburetor. Now it idles pretty good but, if I increase throttle speed at a certain amount it starts missing bad. I'm going to try and post a short video. Just about ready to give up on this thing.😒  you can see reflection perking in video.
