2013 kx450f piston

Recommended Posts

Is the 2012 and 2013 pistons the same? I've looked for top end kits for a buddy and can't find anything for the 13. But there's plenty of options for the 12.

Have your local dealer cross reference the part numbers if there the same then yes

Stock pistons are not the same (slightly updated to -13), but they both fit both engines.

yes you can buy it it will work. I just installed a 13 piston in my 09 and it works perfectly! smoothed out the powerband and has more low end in the 09 model. the piston I took out was in perfect shape and still had the coating on it, but had a different piston profile around the top.

      Hey guys, I have a 2012 KX450f and it is giving me major issues. I will give you a run down of the history of it. I bought this bike a few months ago and have only ridden it really once, yes once! When I bought it everything seemed to check out, it ran fine, started fine, sounded fine, so I bought it. Took it out to ride and the first hill I hit it got really hot and overheated like a SOB and spewed coolant everywhere. I thought to my self maybe it was because we were riding trails slow before so maybe when I actually got on it it got too hot. After that though, it began to overheat every 3 minutes no  matter what, I would ride it for 3 minutes, and have to stop to let it cool down because I was scared I was going to melt the top end. Got home and started inspecting, found out that oil and coolant was mixing both where the oil is supposed to be and where the coolant is supposed to be. After some research I found that the 2012 450 had head gasket issues. Assuming that was the issue, I took the head off and got it resurfaced (it was actually decently warped) and put new gaskets in everything top end related. Piston and cylinder looked brand new by the way. So I put it back together, started it up, and it instantly started spewing coolant and oil mixed out of the crank case breather hose. Like literally as soon as i started it and it would make a puddle on the ground in 10-15 seconds. I'm at a loss here, brand new coolant and brand new oil, brand new head gasket and resurfaced head, and it instantly started doing the same thing again? What could it be? Is it worth my time or do I part the bike out? I have put way too much time into this bike to want to tear back into it again unless it is something cheap to fix, if not I am going to post it on craigslist and let someone else deal with it. Overall this whole experience makes me want to go back to a 250T! XD

      Hi new to this site.
      Ive just bought a cheap kx450f with what i thought would be a minor issue.
      I was told it was only running with the choke on and i thought easy fix, just a blocked jet. So i pulled it apart as must of the person before me and i find a broken soround thing that the plastic case sits on around the pilot jet. So i appoxy that back on unblock the jets and clean it all out, put it back together and now i try starting it for the first time and see the fuel dripping as it was when i bought it. When i look closer i see it is seeping from what looks like a crack in the float bowl. Ahhh
      So my problem is. Looking for a cheap carby might solve all my problems or just a float bowl at worse case. Now i can find many kx450f being wrecked nearby so im wondering are most 450 carbys the same? Will one of a yz450f work? 
      Can someone please help

      I missed tracking where this little top hat came out of in my 2011 kx450f. Was thinking clutch or right side engine cover. Any help would be appreciated I can’t seem to find it in the manual.
