08 YZ450 false neutral 3rd-4th

I was riding at Sand Mountain this weekend when my YZ450 hit a false neutral upshifting from 3rd to 4th. It was towards the end of the 3rd day of riding so the oil was getting old. But it only did it once and after that it was totally fine. Is this like semi-normal or do I have a problem? And I do use the clutch when I shift btw.

thanks

Why aren't we assuming it was rider error?

i think that when its rider erorr it can only happen in 2nd or 1st, unless you hit the shiffter twice.

it never happend to my 06 450, it do jump somtimes cuz of rider erorr but it only goes 1 gear down.

Indications that the problems are rider induced:

> Only happened once.

> Happened at the end of 3 days of riding.

i would run 20-50 oil when you plan to ride in the sand. Sand will make your bike run a lot hotter, and depending on the oil weight your running it may break dwn sooner. I also found 20-50 or even 10-40 make it a lot easier to find neutral on my 08.

I've had this problem while racing a couple times. Mine was when I was hard on the gas going from 3rd to 4th. IDK coud have been an error on my part :p but the bike went into 4th then popped out into neutral and into instand rev-limiter.:lol:

I was running a 15w50 oil for that exact reason, a little thicker oil might not break down as fast. But I read on a different thread on here that short shifting under a load can induce this false neutral. Which I did because I was doing heelclickers and I wanted to just concentrate on those instead of shifting right before the upface.

I think i may be developing a problem with my 07. Everytime i go up a hill hard on the gas in third it hits a false neutral and then clunks its way ito fourth. It's a pita. I have even went up a couple hills with my left foot completely off the peg, and it still does it. I'm looking forward to some more posts.I would really like to figure this out aswell.

Are you saying that, on the '07, you are already in third and then, under a load, it pops out and ends up in 4th?

That would be worn locking lugs on the sides of the 3rd "wheel" gear (output shaft) and the 5th wheel, along with damage to the #3 shift fork.

Yes that is what it does. So you are saying that the dogs on my third gear are probably starting to round, and that my #3shift fork may be bent?This is what i was leaning towards, but it's good to hear it from someone else.I guess my problem doesnt really have anything to do with a false neutral, although i do miss gears its usaully rider error.doh!

That's what it sounds like.

I never had a problem with my 06 450, but my 08 450 seems to find a false neutral between 3rd and fourth as well. It happens at least once a weekend. Seems to be when I'm hard on the throttle.

I asked a tech at my work(mx shop) and he said it is possible to not shift fully into gear. Is that true? Can you miss a shift like that from 3rd-4th by being sloppy with the shifter?

Of course you can. If you apply too much torque before the gears slide completely together, or just don't move the lever far enough, you miss.

ok cool, so as long as it doesn't do it a lot, im good.

thanks

In 2006 we bought a new 06 450. From the first day it had problems with the 2-3 shift. It also would drop out of 3rd from G forces like jump faces. I changed shift forks, shifter arms, and 4 gears but could not fix it. A lemon ? Possibly but it could not be trusted. I traded it off with less than 15 hours on it for an 06 450 Honda. I do still have my 05 YZ250 that I think is the best bike ever made.......

My 2008 is hard to get into neutral when running. But the bike only has 12 hours of run time on it.

I have a 08 aswell, but I don`t think its too difficult once you have got used to The Feel. However, my dad misses the neutral 4 times out of 5.

That's clutch drag. Totally different problem. Start with adjustment.

False nuetrals are a common problem on these bikes when being ridin aggressive. Thats why the shift forks were changed for 09, many many complaints of this from racers.
