The_Hunter · DTR Member

have you got the Haynes manual? i have a pdf copy if you want?
there is a large section on bike failing to start

louisBOSS · DTR Senior Member

Right start here

Take plug out , put on head sparking ?
fuel ? /Put fuel on the plug , if it starts you have a fuel problem to the cyclinder
Compression , does it have any compression

bkray · DTR Senior Member

yh, mate, go check the easiest things first that you might not have, like the cut out switch, i had that problem. :L
check the fuel switch is on, and infact, if you have fuel in the tank although i shouldnt imagine its been run dry. >.>

well jus had a quick go at starting the bike... made sure it wasnt the kill switch which it isn't..... the fuel switch was on as well as the choke and petrols in the tank??? erm if its the battery howq would i know and if it is how would i charge the battery?? sorry bout all the questions people

Seiki · Admin

You can either buy a charger or take it to a garage to get charged

carl13671 · DTR Senior Member

Sounds daft,but are you using the choke the right way round???
Pull it up for on and down for off.

reefvodka · DTR Member

erm the choke is behind the switch to turn on the fuel yeah?? am i thinkin the choke is somethin else?? lol

carl13671 · DTR Senior Member

i think you have found it,
Its like a thin piece of metal sticking out of the left side of the carb

haha jus makin sure.... guess im gonna hav to wait till my mate comes and have a look at it to see why its not startin

CooS · DTR Senior Member

The choke is next to the ON/OFF fuel tap thing mate.... smile

If i was you i would do this:

- Change Spark Plug (new one)

If that dont start her up then try this:

- Put a tea spoon of petrol down the barrel (take plug out)

If that dont work then try this:

- take plug out and get a compression meter thing to see if it is the piston (about a 5r)

And if it is low on compression, im afraid it need's a rebuild! It could be from multiple things from heat seize to bad maintenance

well i bought the bike sunday from this kid, he was riding it then and i sawc him start it up wiv no trouble, mus be me doin somethin wrong???

CooS · DTR Senior Member

Errrmmm that is weird mate, in that case make sure you are doing this:

- Kill switch = OFF (the red switch to the left of the throttle, make sure its on the setting with an arrow and no cross through it)
- Fuel = ON (make sure there is fuel in tank lol) (the fuel tap is the left side, just below the tank)
- Choke = ON (push it up, toward's the tank, its on the left side, below the tank, metal lever)
- Try bump starting it (battery might not be powerful enough)
- If start's run for 1-2 min's then......choke OFF!
- Ow and also check there is 2 stroke oil in it lol

P.S if the worst was to happen, it sound's like it could be a heat sieze! Because my old Scooter (50cc 2 stroke) heat siezed, i was riding in the morning to college and all the way it kept miss firing but full working as normal! Then i got to college it started to splutter then cut out, and i tryed everything but had no luck had its fully rebuilt including the barrel as it had sized and ****ed barrel up

i say it sound's like it could be because, my scooter started fine but cut out when any rev's applied then it FULLY stop working!

But it most likely is somthing little, it's just figuring it out disbelief
