Jumping Out Of Gear

Post by Jamz »

Everybody gets the odd false neutral, or sometimes an unclean change from first to 2nd.

But lately i've been noticing a lot of times, especially during overtaking, the bike kept jumping out of gear into neutral.

First i thought it was me being crap, so i started being careful, and it seems that it jumps out of 2nd gear at 8,000rpm or over. :?

It's fine in every other gear, and in 2nd it pulls fine in gear up to 8000rpm, then *PING* as if by magic it jumps into neutral!!! :x

It seems to be more a problem with the selector (i have had this apart so maybe i've put it back together and it's a bit out) - but wouldn't it do it in every gear??? :?

Likewise, if teeth were stripped from the cog, then surely it would affect the lower revs when you bear in mind i have Um Plenty Big Torque well below 8k.

Any ideas??? :?

Oooh and it's worth mentioning my clutchplates have been worn and slipping for a few months - but don't think this would actually affect gear selection?

LOL don't go telling me i've gotta change the chain again!!! :cry:

It's only a couple of hundred miles old and in excellent condition! I take good care of my chain and adjust and lube it regularly.

As far as i know the clutch cable is ok - wouldn't both of these affect all the gears? :?

Top Tip try changing your oil to Silkolene 10w40 Ride

Yes the cheaper oil i used to get a lot of false neutral then i changed my oil seems to be okay dont know why but for £10-£15 could be worth trying if it works for you job done if not then at least you have changed the oil

And no i dont work for Silkolene :D :D

Hope this does help out

My issue is with spending around £60 on the clutchplates and gasket when i'm gonna need that money to insure a ZX9-R... :|

Chances are i'm selling the 444 as is....

LOL that's not gonna be the best selling-point for it!

If i can sort it simply and cheaply before i sell it, then i will.

Or i can at least let the buyer know exactly what they'll have to do to fix it. :D
