Street Cup Won't Start In The Cold

Are you saying it is turning over but not firing up? Is it turning briskly or sluggishly?

 

How long since you refuelled?

 

Provided the kill switch is set to ‘run’ are you leaving the throttle alone? It is always tempting to tweak it slightly but cold Triumphs need religious adherence to the owner’s manual. And if you have previously flooded it....

 

Try an aerosol cold start can before deciding you have a real problem. About £4 from Halfords sprayed in the intake.

 

Solenoid?is it actually turning over (but not firing) or just sitting there clicking?

 

If it’s turning over then that implies that the battery is doing its job ...

which means it may be damp (as Cal sort of suggests).

 

Cold weather kills batteries; it actually lowers the amount of power output. It would be very interesting to put a voltmeter on the terminals when you push the starter on a warm day see how many amps it puts out, then try it again on a cold day.

If you have started it when it's cold, does it then start again easily once it's warmed up? If so then I'd be looking at the battery... Or, when you try and start it from cold, does it seem to fire on all cylinders, or is it missing? If so, tempting to say its damp.

Once tried to fire up an old Honda in the damp and in the dark. Arcing all over the place, like a bloody firework display! Wd40 often helps expell the damp.

 

Boil the kettle , lift seat or whatever's necessary to access the battery , pour boiled water (hot) over the battery , a bit at a time ! Raise the internal temperature a few degrees , try starting it again !! If it starts your battery is weak , put it on a float charger.
