Kx 450 2014 1 hour failure today

<< < (2/3) > >>

sandblaster:
Owning a bike salvage company I have a unique perspective on 4T's,
I get way more CRF450's and CRF250's then any others.
Next I get a fair amount of Yamaha's.
Then Suzuki's.
It's then a toss up between KTM's and Kawasaki's but I get very few of either.
This could be due to the area I live in as I don't know which of these bikes are sold the most.
I sure hope you get taken care of.

Clintc:
Run in full tank if fuel , dropped oil , put filter in
Went out first lap out  started to cut out before table top
Then just turned off
I then restarted are rode back slowly to pits
Stop at pits it started overheating and making squealing noise

Filter is correct

It was making funny noises when I was running it in.
I've come straight off 6 years with a honda.
But the guys down my local track say kawasakis are noisy.

I found on the 14 that depending on the conditions like temp and altitude affect the mapping.  The chips that come with them only help a little.  I found on the last one I worked on that it was running lean, it ran fine for the first ride and then after that started running weak in the top and overheated.  He brought it over to me and I pulled the plug and it was way lean, at about an hour on the bike.  Did looking and found they needed a remap to make it run right.  Your does not sound like an isolated case.  Let us know what the dealership says.

If it blew up with so little hours I'm sure Kawi will stand behind it. I heard of a 12 that put the rod through the cases but with any brand your going to have a percentage of failures, unfortunately yours may one of them. I had a 500 that the  casing was not cleared out on the discharge of the water pump, bike was still running after several weeks, I asked for a complete new motor, they gave me a complete new bike, sure it depends on the relationship you have with the dealer. I currently own 4, 450's and have bought and sold maybe 6 more with never a problem with the bike. as Alward says they are lean from the git go, maybe  some emissions thing or bad gas, not sure but you need the tool to richen them up, it also gets rid of the popping on decel.

the amount of hondas you get most likely has nothing to do with there reliability. look up the sales on honda VS all other dirt bike manufacturers. even when you go to the track (at least out here) theres 50%+ honda. Different story at the desert races, all orange.
