Jipin where is neutral?

[jim5.0]

Hello all,
A few months back I bought my kids a secondhand Chinese bike.

It has a Jipin engine with a centrifugal clutch & goes really well now. The engine has a red sticker on the side that says "125cc" and it certainly goes quite well like a 125 would.

The trouble is neutral is very hard to find with the engine not running and completely impossible to get with the engine running.

I presume that the gears are one down and three up (am I wrong here) but the neutral that I am finding with the engine not running may be a false neutral and not the real one.

Thanks, Jim...

i find it hard to get neutral in 1 down 3 up engines, may just be me tho

it sounds like its 1 down 3 up

with trying to find neutral its like a half click so dont just click up like you normally would changing gears

sit on the bike and rock it back and forth while going through the gears...you'll find it.

my quad is 125 centrifical clutch and the gears are as follows
toe down all the way is reverse then heel down nuetral,heel down 1st, heel down 2nd , then heel down 3rd if that helps at all

That's exactly how I do it with the engine off and it's the only way to get neutral but that is just not possible with the engine running.

Just to elaberate on that a little more..
If it is 1 down 3 up, kick the gear lever all the way down , you should find 1st gear..
then when riding or sationary if you kick up a gear thats second right, and so on......
but when your in 1st dont do a full kick up to second gear just do a half or soft flick up
that should be neutral there...

I think that therein lies the problem. I can click one down to first just fine but there is no half or soft click to neutral the gear lever just moves up and then into second.

I've been riding dirt bikes for 30 years so I think that I have gotten my children a bike with a sick gearbox somehow.

yep classic 1 down 3 up neutral syndrome..

not saying this is the fix for your engine but this fixes most..

disregard the first lot of writing on it.
the problem is that the detent spring for the gear drum arm looses tension, or even sometimes just works its way loose..

obviously this fix only applies to those engines with a star shift gear drum..
