iv got a volt meter and checked each cell 1 by 1 and they all read 2 volts then checked the overall voltage which was 12, i then put me battery charger/conditioner on it over night .

its helped but it still wont fire up when standing

but as iv said b4 after a 5 min drive it will start up without pushing it, but if it is off for longer than 10 min i have to push it again.

iv set the mixture screw so the bike runs lovely with good acceleration and top speed and iv set the tick over screw so it just ticks over nicely

i got this bike about 6 months ago and it started and ran fine, i could start it up 1st time every time, then when i couldn't get an air filter for it i had to put a performance one on it , then re jet the carb then put a new exhaust on

and since iv done that it wont start without pushing

You should get around 13v ideally 13.6 from a good battery in a stand alone voltage check, with pipe carb and filter mods you are asking a lot of the starter/ cdi combination. All that extra gas needs a comparatively bigger spark to get it going.

The bit i'm curious about is the dry plugs when on choke, are you sure the choke works? As i have never had a bike that refused to start on choke have dry plugs unless the carbs were the issue.

She will start on the bump because of the much greater draw when the engine is spun on the bump.

Try squirting some fuel down the carb as you crank her over, use an old 3 in one can or such.

edit..... just noticed you said one carb

hi when i removed the carb i gave it a dam good clean and replaced the choke cable, iv checked the choke and it works better than it did when i 1st got the bike,

but as iv said surley the plugs should be smotherd in fuel when u try to start it with the choke but mine are dry as a bone

iv done a plug chop and all seams fine, the mixture is as near to spot on as i can get. so im stumped

it dont take alot to bump it

normaly i push in the startor switch for about 15 seconds then push it in second for about 9 steps then dump the clutch and it starts.

but im just thinking of when the winter comes around cause i use it in all weathers i dont fancy trying to bump it in the snow!

and yes its just the 1 carb thats shared between the 2 cylinders

dear frien.you shold use NGK dr8es-L sparks.and the problem in your bike is the carb balance problem.you should balance them correct.if one of the carbs take more fuel from the others it will not easy start when it is cold.try to adjust the balance screws.

roadstar 125??? )) sorry dint see your bike.have a compression check.if your bike is weak this is the problem when starting cold bybye

yeah its a sachs roadster (german ) 125 that uses the virago v twin single carb engine. and as for the compression check i dont have the funds to get one done, but as iv said b4 its only stoped starting since iv put that new air filter on and re jetted the carb, it works lovely when the engine is running and i can get 70 out of it on a straight but its just this starting problem thats holding it back.

once iv got that sorted im going to hack it to pieces and chop the back end off to make it into a custom fighter.

should shed a bit of wheight too.

How do you adjust the mixture on the xvs 125 my plugs and exhaust are sooty. i had the bike tested last week ad the CO was 9!!
