starts with easy start then starts first time afterwards...

Hi there,

I have a piaggio zip 125cc 2002... i am having problems getting it to start when cold? When i got the bike not only would it not start when cold but it wouldn't rev beyond a fast tick over... it would just die...

I took off, cleaned and reset the ignition pick up, cleaned the carb thoroghly, cleaned the air filter and unblocked the feed to the vacuum hose from the inlet manifold...

and voila.. once started and warm she revs beautifully and seems quicker than my other one (which is exactly the same but a 2003..)

there is quite a lot of ticking noise coming from the top of the engine... i'm thinking the valve(s) may need adjusting (havnt done this before, any tips would be appreciated..)

But still at the moment, I need the easy start to initially get her started in the first place??

could anyone offer any advice or suggestions please.

cheers.

 

Re: starts with easy start then starts first time afterwards

if its a 4stroke and the valves are going then it will be a bastard to start when cold! but usually its just as bad if not worse when hot! do you get any back firing from the exhaust or poping or banging. ticking noise is usually the tappets and not the valves

 

Re: starts with easy start then starts first time afterwards

thanks for the reply mate..

don't get any backfiring.. once started once (easy start) she will start on the button... its just the first attempt that is a problem..

As far as tapping sound, don't you adjust the valve clearences via the tappets some how??

From what i've found out there is a locking screw which you can reset clearences which sounds a lot easier than removing cam shafts and replacing shims etc..

have you ever done this?? any advice?

Some one else has suggested there is a choke problem or an air leak...

i will test the power into the choke and if its good i will swap the unit for the choke off my other zip which starts first time every time..

cheers
