False neutral between 3rd and 4th

[specter]

i have a 2007 kawasaki GPX 250r and have noticed when riding hard that when you change from 3rd to 4th lightly it slips into a false neutral?
is this common and can it be fixed
cheers

ive had it on a few bikes, poorly made kwaka gearboxes probly the cause, just make proper shifts, no half shifting

[chanceyy]

Have to agree with Bogan there, my ole RZ used to do that if I did a soft, (half arsed) gear change, needed a really positive change to stop it doing that ..

yea yea i thourght that too.
i was just wondering if there was a mechanical fix

Make sure the gear lever is adjusted properly on the spline too. If you have to really try hard to make the change perhaps you could move it a couple of notches on the spline so it is in a more natural place for your foot to reach and easily make the change.

The more this happens the more damage is caused to the dogs on the gears.

Kawis do have a bit of a rep for casual gearboxes on some models (ZX6s spring to mind). Your best low effort approach is to 1 check that you are getting full unfettered stroke of your lever & both parts of linkage (if fitted) are a parallelogram, ie same angle. The next thing is you could try buying a Factory detent roller (check factorypro site) & possibly a slightly stiffer spring for said detent roller.

You might find at the desperate end some oils are a bit slicker & aid clean shifting. Ignore additives.

Failing that it is strip the gearbox & shim for more engagement/ undercut the gears, but that's another story.
