Peugeot XR6 wont start properly!?

Recommended Posts

Hi I'm Rick and I'm new to TMBF I'm 16 so can only own a 50cc bike but 17 soon and hoping to get the CBR125!


http://www.youtube.com/watch?v=zKqYk3phdiM


It has had a new CDI, spark plug, spark plug cap, new battery and I've cleaned the carburetor yet it won't start!

It starts up like it did in the video with the choke fully on but if i let it drop RPM it will stall like it did I've cut out about 10 minutes of me running up and down the road as you probably don't need to see that.

It has had a new top end rebuild since a piston ring snapped and scored the piston.

I've replaced the piston rings and the piston itself just not the cylinder all new gaskets and one of the top bolts is missing would that matter?

The air filter was removed for this video as part of testing the bike.

It's had all fresh petrol, 2 stoke oil etc.

It is Peugeot's poor excuse of a motorbike called the Peugeot XR6 50cc 2 stroke.

Minirelli AM6 engine everything is stock on it.

If I undo the screw which the bowl is located fuel pours out so fuel is definitely getting to the carb.

After is started like in the video the plug was wet and sort of black, wiped off easily.

Sorry about the poor video i had my iPhone taped to the mirror on the bike, don't have one of them fancy GoPro things quite yet! =)

Any help would be greatly appreciated, thanks!

Welcome to the Forum mate........introduce yourself in the Newbies section when you get a mo....... :wink:


When you say a bolt is missing.....where exactly?.......if it's on the cylinder head you could have problems..... :wink: If it will only run with the choke on I'd be looking towards low compression as the problem. You replaced the piston and rings....but was the barrel scored?

Hi I will do that right away, thanks! =)


Yeah there is four bolts on the cylinder head and one is missing.

The barrel was scored but only a slight bit, hardly seemed worth replacing as I'm running low on cash.


Thanks!

Yeah....a missing bolt on the cylinder head wont be helping things..... :wink:

 

Would it be doing what it's doing though? I'll go to partsco soon and get a replacement, thanks =)

Well....if you have a decent spark and fuel is getting into the combustion chamber the most likely thing to stop it running correctly is lack of compression..... :wink: I had a loose cylinder head bolt on one cylinder on an RD350 years back....it ran like sh*t......and leaked fuel/oil from the head gasket area.....so, a missing bolt could cause your problems..... :)

If that was the only problem with it that'd be great, I'll go and get a bolt tomorrow and let you all know, thanks =)

i would say replace the head gasket as well but it certainly will never run with one bolt missing completly as the compression is blowing out round it

 

I've replaced all the gaskets in the top end there is just that one bolt which I'm hoping is that's wrong with it =D Thanks =)

where you have tightened the remaining 3 bolts down it could of damaged the head gasket replace the last bolt and washers if there was any and hopefully you will get away without doing head gasket again

I've been working all day trying to earn as much as I can for a bike at 17 so not been fiddling with it today, I asked my mum to go get me another bolt god knows what she got me probably something completely wrong but I'll be sure to try that bolt very soon, thanks for your patience guys and gals :D

the washers spread the load slightly for the nut to grip more of the surface look on this picture it is item number 6 is the nut and number 7 is the washer http://www.vespaspares.co.uk/HTML/spare ... 82151.HTML it would be worth ordering the correct bits from someone like this as you then know they are right

theres the other reason it wont start have you checked the condition of the barrel as well as i bet that also has huge score down it.you must of not fitted the circlips correctly looking at that or you put the piston in the wrong way round

 

This is going to sound idiotic but does the arrow go in facing forward, towards the front of the bike?

This is the cylinder and gaskets, is it bad enough for me to get another cylinder kit?

I seriously appreciate everyone's help given to such a newbie so far on this forum. Thanks a bunch.
