2005 Honda Recon Engine is Seized

Can you try to free up the piston from the jug? Because we need to figure out what happened and go from there.

Try spraying pb blaster in the spark plug hole and let it soak for a bit. Then just a little turn to free it from the cylinder wall. Then check your timing. It could be binding up in the valves and not letting it turn.

Or just take the jug off and let’s start inspecting parts to again, see what happened

I’ve blown pistons and luckily was able to figure out what happened. Could be simple, could be time for more. But we will figure it all out together.

We are all quadcrazy.

In would start by pulling the cylinder off of the engine and then the piston out.  Take a good look and see if you can find where the failure happened. Maybe the wrist pin clip came out, the rings maybe went etc. As @06kfx440 stated check the main crank shaft for any play.  If all else checks out on then your good to go.

If it’s just the cylinder head and piston then try to locate a new or used on on eBay.   If you find a good used cylinder head then spend the money and put a new piston in as well.  Makes sense to do this since your going through the effort. Make sure your oil pump is working properly and that the oil is getting to the head and lube all areas up good prior to start up. 

My guess is it was prob a failure of some sort with regard to the piston and the wrist pin clips or rings.

      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, what is the best method for installing bearings into their race? I've set one in place and tapped it down until it was metal on metal. Is that sufficient? Surely it's not supposed to go into the race until flush? Also. does the coil spring on the seal go into carrier bearing housing not facing out? Thanks! 🙂 Seal goes in until flush correct?
