Lingering revs and no running without choke

[declan]

My bike has been started for the 2nd time today and it don't like to run without the choke on it will slowly die and if I adjust the idle it kinda makes the bike a little erratic like revving to 3k on it own

[declan]

@declan I should add the pv is currently disconnected as I need to solder a snapped wire

[Calum]

SO I always found that the bike never started with the stock carb without choke. So choke from cold is normal.

Once warm however it should be fine.

I would make sure the throttle is not ajar.

[declan]

@Calum I did install a throttle that's not meant for it and had to make it work so I will double check it just not sure it will run fine without choke as long as I hold the throttle on slightly

[declan]

@Calum do you think the a/f mix is off and if so lean or rich?

[Jens Eskildsen]

Its lean If it wont idle without choke when warm. Is the airscrew around 1,5 turns out?

You need to clean the carb, pay special attention to the idle jet, and the internal tube between that and the airscrew (remove the airscrew and make sure the tube is clear by spraying fluid (carb cleaner, wd40, brake cleaner or compressed air ect) through it

@Jens-Eskildsen do you know of any carbs which are a direct replacement for the dt? And not got to the screw yet will do tmoz thank you for helping me out btw.

[Minia]

A thorough clean of the carb might be the trick. Certainly did for me numerous times.

[Jens Eskildsen]

The stock carb seems to work fine for the bike, so no I havent reserced if another one is bolt on, but wouldn't think so.

[Calum]

I run VHSA, inlet needed some modifying mind you. Works a treat.

[declan]

@Calum what just making the hole bigger to fit the carb?

[Calum]

@declan Yeah tht did the trick.

You can buy a 28 to 32 converter also.

@Calum thanks! What revs do the the dts go to on full choke
