My Bike is starting to become very hard to start The battery is fully charged and good, it cranks over for ages before its able to start and then the bike seems to work fine although it does feel like i have a slight lack of power lately Just wondering do valves tighten up over time just in case i have a tight valve? i have recently changed the spark plug as well so it isn't that any help is appreciated

yes the valves can go both ways m8, when i bought my scoot the valves were too tight.
when hammered the hell out of for a continuous period, tappets (valves) vibrate badly and they aren't oiled very well, due to their location.
is it the cold weather maybe?
there must be some form of distributor for the timing, on a car this would be a distributor cap, a spray inside this cap with wd40 / damp start would alway do the trick as they are water repellants.
the cold damp weather is a female dog for electicals on an engine and a scooter is hardly well protected from the elements.
when you changed the spark plug did you make sure the spark was strong visibly?
go backwards through the electrical system starting at the battery, tighten all connections and grease where appropriate (battery connections should have grease on them to protect from the wet).
good luck m8, there's loads of fun to be had diagnosing a problem, at least with a scoot you got more chance of being in the warm and dry whilst doing it lol

Try to shorten the vacume pipe going to the fuel pump. This pipe should be as short as possible. If this pipe is too long or become bad, the fuel pump will not pump fuel to the carb. Shortening the pipe made my scoot start better when cold.

i upgraded my fuel filter to a bigger better see through one about a year ago and theres plenty of fuel in the fuel filter so i don't think its a lack of fuel getting to the carb unless i need a new fuel filter

I could also see fuel in the filter. Try removing the vacume pipe from the engine and suck in it. Then cut it as short as it can be. It takes only 10 minutes to do. I have plans on changing that pipe to a stiffer one. I read about this problem on a finnish forum.It is very common in Finland during the winter. Then two days ago I had this problem myself...

mine starts up fine at the moment, but i do have to give it some throtle, and it is stored in a garage. i think its down to the temputure, becasue my bike plays up when its cold, where sometimes when im stuck in traffic or go to pull away from some traffic lights, it just stalls, no matter how lightly or hard i pull the throtle? doese anyone ells get this?
could your prob be to do with the fuel mixture hypojam or the choke?

I think it would definetly have something to do with your fuel mixtures being wrong all i can really say is adjust the idle fuel screw and if u have a moveable washer on the pin adjust that to

ok, i have adjusted the washer on the pin thats in the carb to the second from last notch down, I'm not sure where the idle fuel screw, is that the normal idle screw your talking about?
also is all this normal to happen straight after you have de-restricted it? because its starting to really bother me.

Idle Fuel Mixture Screw Adjust that to 2 1/2 turns out from in and that should fix your prob

ok thanks alot, are you sure it is 2 and a half turns becasue 1 of my friends says its only about 1 and a half, but i think i will go with your advise, as you sound like a pro at this sort of stuff

it gonna be a lil diffrent for each
varying factors such as how much a person thinks 2 1/2 is how tight it is to start with the width of the screwdriver handle etc
set it 2 turns to start with
i set mine to 2.5 it has improved greatly there is some power loss when fully open i put this down to the cold tho

mmm ok tho only thing is is i have to take apart my seat to do it so i cant realy test it once i have done it to see if it has worked or not becasue i might have to turn it a bit more. do you recomend anything? i think im just going to have to do it 2 and a half turns and then see if it works.... if not i will have to take it apart again and do it all again. thats a good point that you made about depends on how many turns from tightness, shall i screw it up tight and then un-do it 2 and a half times or not so tight
sorry for making a pigs ear of it

It doesn't matter about the screw driver either! As for tightness, I would screw the screw in quite gently, until it stops, then stop. All you are trying to do is cut of the fuel flow, so it doesn't have to be too tight. Then make a mental note of the angle of the slot in the screw, using this you can judge 2 and 1/2 turns anticlockwise
