Aerox taking the piss..again

Right, hi people,, my rox has been being a total bitch lately, and after spending £500 on worthless labour by complete retards, im now stuck with yet another problem......

My bike now doesnt start, tried different/smaller jets and nothing......it was running a 100 main (which is too big for a polini sport+17.5mm carb+yasuni R+4.5g rollers+malossi multivar) ... and its starting to get me really annoyed because iv now spent over £2300 on it and the P.O.S doesnt even start !!! .. dont know if it bogs or what because it wont start...i havent got a CLUE whats wrong with it....

Anyone tell me why its not starting, even though everything is practically brand new ? got compression+spark+petrol+oil and whatnot... but it refuses to start and im honestly losing my rag with it.

Not much to go by, but can anyone help me out ??

 

is the fuel even getting into the carb and out of the carb ?

Have you check if your reeds are broke?

 

Reeds are fine mate and petrol is gettin about the place so it isnt that..

 

hmmm sounds abit strange have you tried starting it with the air box off for onyl 1 sec obviously so it doesnt damage the engine to see if there is a air blocked in the airbox or filter whatever you have.

is the idle screw set right ?

 

It doesnt start mate, at all........ take the airbox off and it gets worse and doesnt start still......

Idle screw has been fiddled with at every single position to try get it started and fail every time.

 

what did your compression test come in at and im taking it as you have checked to make sure your cylinder isnt leaking water into the mix ?

and whats your plug looking like ?

 

Plugs fine mate....... and compression is good too..... and no water leaks anywhere

 

so it doesnt have weak ignition or anthing ?

 

Nah mate, its all good thats why im annoyed so much lol.... i dont get it,,, bikes really f***ing me off now, shoulda scrapped it... £2410 spent on it and it doesnt start..what a joke

 

have you got a manual choke? if not that could be the problem

 

yer i have mate, its never been a problem before though, and sometimes have to start the bike with the choke pushed in...

 

i dont now what else it could be :/ take your cylinder head and barrel off and make sure theres no shit in your valves ect. also you havnt got a blockage in your exhaust have you ?

connor if the auto choke was stuck it wouldnt make a difference just wouldnt go anywhere but it would start

 

no point taking it off,,, it got taken off a couple days ago and all is fine mate... literally everything is fine,..but it just will not fucking start....

Exhaust is a brand new yasuni r so it hasnt got any blockages

 

how strong is the spark?. Rest a spare plug against the head, attach the HT lead and turn it over. You should see a very clean fresh spark.

Set all the mixture screws to standard and go from there....

How good is the battery...have you tried a booster to start it. Some ignitions wont fire unless theres 14V to them .....even tho' they'll turn over OK

 

Im pretty sure its a good decent spark mate,.. we checked yesterday and all was fine with that, didnt start but still had a strong spark.... and tbh..
I dont know what standard is.... all the way screwed in or out or ... ? iv also got 2 screws on the carb, both next to each other at the idle mixture screw, what is the other one ??

And the battery is on charge so will be fully charged up by the morning, its a 12v battery but only had 4v in it earlier...

 

take air filter off and put your hand on carb and try starting and adjust the air with your hand throttle / might help . also put some premix into your cylinder trough spark plug hole

 

Iv tried that mate, it just doesnt wanna start ... it came to life for a split second then died and exhaust sounded like it had a 'pop' to it.... also what are the 2 screws on the carb? one is idle mixture screw dunno what other one is ?

Might give that a try though, just means i gotta drain some petty from my tank as its hard to just get a lift to petrol stations for me...plus id need to buy some more 2t oil

 

well if it started for a second thats not electrical problem it petrol , when u take your petrol pipe off does the petrol come out ? try sucking the vacum pipe aswell

 

Iv done all that too mate, iv done everything i can think of on /to that fookin bike and iv got Nowhere at all i even put the 100 jet back in there and it now doesnt start..even though thats the only jet that got the bike started the smaller ones wouldnt start or they would and you couldnt touch the throttle or it'd die....

 

get some eeasy start or pour some premix straight into the cylinder and put plug back on and see if it starts then youll know if its a fuel problem
