Rather difficult question to answer

[Nzpure]

bike does have a problem with third gear, at low revs it tends to jump out, i just miss 3rd altogether and go from 2nd to 4th, its fine shifting down though.

I know its almost impossible to give the 100% right answer with out more info/looking at the bike. But whats likely to cause this, Does it sound expensive to fix or cheap if you do it yourself?

Make and model of bike would be helpful, or you could take to an outdated black mechanic specialising in outdated black bikes.

Dogs are worn or a shift fork is bent. I'm going with the dogs being worn.

Fixing it yourself depends on how mechanically minded you are. Have you ever taken a bike gearbox to bits before?

LOL its not for my bike its one im looking at buying its a 07 zx6 ninja. ahahah should have mentioned what bike it was ahahah. I am mechanically minded, Never taken a vehicle to a mechanics yet.

Nope but there's always a first time.

Protip: mechanics LOVE to get boxes full of random bits from customers and the instruction "Oh I know whats wrong all you need to do is blah" Cost you a hundy and a box of beers tops.

I would just replace the detent spring first and see what happens.

this would be my diagnosis based on what youve said too. Id lean towards dogs more than a bent fork though.

its likely to be the dogs if its jumping out of gear.
Alternatively a maladjusted gear change lever can cause this, if the fulcrum is not correct for your foot it often doesn't slot in correctly.
Had it on a few bikes, and with a twiddle of the 10mm nut its all good again!

Lol yea mechanics just love that. Just tryin to get an idea of cost to fix it, worse case scenario kind of thing. Gives me leverage to push his price down and make it a worth while purchase.

[tigertim20]

jump on a bike specific forum, and have a looksie through threads for those who have had the same thing, and what it cost to get it sorted.

my question would be... WHY is a bike only 6 yrs old jumping out of gear? What K's has it done? If low.. I'd be very very suspecting of an abusive life being had by said machine... whats next in line to fail???

[SimJen]

if its a cassette type gearbox then you don't have to split cases or remove motor from frame.
But if its not, then could be big $$

done 40 odd k, Apparently a common problem. However my searching skills appear to be lacking as i haven't as yet found a fix or even whats causeing it for that matter.
