Bike starts well but stalls as soon as goes in gear

[drmmanish]

Hi all,

I have a cbf 125 Honda which has about 8500 miles on it. Started the bike today..no issues.. But as soon as bike goes in first gear the engine stalls! Tried it a few times..same problem. The clutch at my end seems to be working fine. The engine on start sounds absolutely fine.

Was wondering what the problem could be.

Many thanks for advice.

Side stand or side stand switch problem?

Heh, I tucked the switch on my HN up under the seat straight out of the crate - they're a known failure point on those bikes.

The CBF125 side stand switch apparently looks like this:

Find it, make it not broken. Give it a clean with WD-40, iso-propyl alcohol, or whatever you have to hand, bit of a wiggle, clean any crud off, see if that gets you going. Worst case you can just remove it and either leave the circuit open or short it, depending on whether the switch opens or closes it with the stand up.

Put the bike in first with the engine off, pull in the clutch and see if it rolls. If it does move onto switches.

Hi guys,

Just to say a big THANK YOU. It did work. I mean when the bike is not on the side stand it works well. Is it supposed to be like that; I mean when on the side stand is it meant to not run?

Many thanks.

Ps: spent my weekly petrol money in one day on tube!!
