no petrol getting into the top end?

hi
there is no petrol getting to the top end,
i have taken the carb off checked for blockages or dirt but its going through perfectly.

it was working fine all day until then it started to cut out every time i idled now it just wont start.
i think it has heat seized but i aint got a clue.
anyone got any ideas??

 

whats the compression like?

does it take as much to kick over as usual

 

it kicks over perfectly
sounds like itds just bout to start and just doesnt lol

my mate said when his heat seized it sounded exactly the same

 

my speedfight does this :/


just wont start and theres beast compression & a spark, no fuel's getting to top end tho

kicks over fine, but just doesnt start, splutters like its gunna strt just doesnt

 

vacume/airleak?

 

thats exactly what mine does breamy
how you check for vacume/airleaks??
anyone else know of any possible reasons for this
cheers

 

quick thing to do which might solve it, whip off you vacuum pipe, apply vacuum/suck for about 20seconds attack vacuum back on and see if it starts

if it doesn't unscrew the float bowl about 1 turn on one side and tip it slightly see if fuel comes out

oh and make sure your vacuum is attached on the fuel tap and carb

 

done it all

r lasses dad reckoned there'd be a air bubble or summet in teh vacumn as i ran the scoot bone dry, but petrol pisses thru the carb when float bowl's off

fuck this

Some fucker come fix it for me, ill pay you and feed you etc, ill even skin up if your into that stuff

pm me

 

done em all too still nothing

i still think it could be to do with my top end
but are there any more possible errors which doesnt involve taking my top end off?

 

someone glued ya reeds toghether?

most probably an air leak make make sure your inlet theres no tears or rips in it

 

theres fuckall wrong withit

no air leaks or fuckall, stripped carb etc still fuckall up was nothing in jets or owt

i reckon its the wank immobiliser or some bollocks

 

If you believe its heat seized, the compression would be out the window. Drop a compression test on it before resorting to stripping the top end

should be around 120psi for a good one and at least over 100

 

well 2day i swapped my inlet and reed blocks with a couple spares i have and got the bike started but its a struggle and it just cuts straight out after releasing the throttle and lets out lots of smoke.

 

wheyyyy got petrol getting to the top end but also coolant i thinks i may need a new gasket
sound about right to anyone else??

 

mayb where u was trying to start it wih broken/open reedsd its filled the bottem end with petrol, try takink it for a good ride should clear it's self through

 

earlier i started it up with a strugle and tried taking it for a lil ride but when i tried going up the drive it was doing less than 1000 revs and just cutting out and sending me back down the drive lol
