Kickstart has a life of it's own

[Motorman33]

Please help.

Whilst riding motorcycle the kickstart starts activating, up and down. Very dangerous. Fortune was with me as was going slow at the time. Please explain what is wrong and is there a simple fix. Been too many years since I tinkered with a motorcycle gearbox, so for the life of me I can remember very little.

What bike is it for a start?

[WD Forte]

Sounds like the return spring is bad/broken or the pins/parts it locates on has snapped orf
As above, saying what bike you have helps and usually gets you off to good start here.
Not providing relevant info from the start is a good way
to irritate folk and get sarcastic answers

The Motorcycle model is

KYMCO PULSAR 125S

[WD Forte]

Y'see? didn't hurt at all did it?
My lad had a 2009 model and we had the engine apart to fix it up
and I took many pics
IF I haven't binned them, I'll see if I have any with relevant details in it

We didn't have to look at the kick start so this is the most relevant pic I have.
The RH side pic is where we cleaned out the oil strainer.
The kickstart gears and ratchet etc are behind the case casting so
you'd probably need to split case to replace anything.

You could try removing the oil strainer, clutch basket and gear selectors to get enough access to fiddle with it but I doubt you'd be able to remove/replace anything doing this.

If that's all too much arseache,
just strap it up and keep the electric start healthy.
We never had any issue with the lads ES as I recall and again as I recall, the kickstart was a bit wanky to use anyway.
IIRC It seemed to have to travel a lot to do anything useful

Thanks guys. Very helpful.

I remember taking apart the case of a G.P 100 and never did get it working again, so I doubt I will be going down the road of splitting the case as I remember all the hours involved, including reading the Haynes manual. So will most likely strap the kick start in the up position as WD Forte suggested.

Now if the spring has snapped is there any chance of it ending up in the gears Last thing I want is to go flying.


I'm thinking of changing the gearbox oil. Been having gear change issue's for some time. Seen a few customer review on this model motorcycle and seems there may be gear issues but hard to tell with customer reviews as some state great and reliable whilst others unreliable and gear box problems. So I don't know what to think. What are your thoughts

CG125 copy-engine, right?

I'm a novice in this respect.

[Rogerborg]

There are two common engines used in Chinese 125cc bikes: copies of the Suzuki GN/GS125 overhead cam engine; and copies of the Honda CG125 overhead valve pushrod engine. Other engines (or weird mutants like water cooled variants) exist but are far less common.

It looks like yours is the CG125 copy. This means that pretty much anything that applies to the CG125 engine should apply to yours.

Thanks.

Does that mean the Suzuki and Honda parts will fit the Kymco as I can't find many suppliers selling parts for the Kymco Pulsar.

[WD Forte]

Engine/gear box oil is one and the same on those engines
Our Pulsar had the XL/GN copy OHC lump as opposed to a CG OHV type

Broken bits in engine? dunno, possibly
its worth removing the Rh cover to clean out the centrifugal oil strainer
at times anyway, so you could check for debris while yer at it.

Dead easy to work on and parts cheap and easily available
from Ebay, CPMO or even David silver spares

While I'm rantin on...
keep an eye on the cam chain tensioner
Ours had the chain slip causing bent valves and during repairs I found the tensioner to be a bit iffy.
Once we fixed it it was good reliable little runabout

Just remembered the fifty quid bike thread which may have some useful info

https://www.bikechatforums.com/viewtopic.php?t=301946

I stand to be corrupted but AFAIK the Pulsar S has the same OHC engine
as the lads Pulsar LX the only difference is the S has a more 'classic' round headlight and seperate clocks

I also remember:
the exhausts rot like buggery and can often rattle as the inners detach, I migged ours up
Front brake crap, rear brake good
I swapped the vac fuel top for a manual type from my CX spares box
and dumped the vac operated exhaust gizmo system

Thanks,

All useful advice and links. I have downloaded the user manual now so when I find the time will do the service and maybe check for any bits of spring floating about. If I get hold of a camera will send a pic of the engine to find out if it is a CG 125 copy.
