suzuki gs 125cc starts then doesn't

[cousolfc]

I have a 1998 or 99 suzuki gs125es its had a brand new batter, starter solanoid and spark plug, but if I go out for say an hour when I go back to go out it wont turn on all other electricals work (lights, horn indicators) does anybody kniw what the problem may be? Im thinking the wiring

[Efes123]

sounds like a good guess Does it happen every time?

Yeah went for a long ride cut out 10 miles from home came back on after like an hour of pushing, day after started first time went to shop and I little ride round my area, wouldnt start again, went out yesterday for 30 mins since then its not been back on, haven't tried this morning

[Efes123]

If it happens every single time, then it's prolly not wiring. Something is expanding with the heat and causing a problem. Struggling to think of anything starter motor

Does it try to start?

If I go to bump it I get some noise otherwise no nothing

[cousolfc]

Gunna read starter motor section in manual now

[cousolfc]

now no electricals are working and the bike hasn't started today. indicators worker when I tried horn it all stopped

[Efes123]

A real strange one this

I know you said a new battery, but have you put a meter on it? It might be that your rec/reg is frying it, but then I wouldn't have expected it to start the next day.

I'd start from basics again. Get a meter on each point.

[cousolfc]

what do you mean by meter on each part

[Efes123]

[cousolfc]

it does have a kill switch yeah think that could be the problem tbh, wiring loom comes tomorrow going to change it all then ill have a look at the kill switch whilst doing it as I have a spare front brakr lecer which has the starter button and kill switch ill check that one and use thw best one thank you.

[MattWadz]

Could have a shitty earth somewhere, possibly losing an earth or something on the killswitch? happened to my friends bike his killswitch was playing up and it took him ages to work it out as when he held it in a certain position the bike would start, then on or off it would die

Not sure how much use that is to you though

Check your earths and a general visual/continuity check if youve got a multi meter? be really handy to get one if you havent got one, can get them dirt cheap too

When you try and start it the second time, does the engine turn over, but not 'catch'? If so, then I'd be looking at coil breakdown - when a dying coil gets hot, it often won't generate a spark.

got 70 miles out of her today not had the usual problem. since I first postedd this thread today was the first time it worked seems to feel smoother. but its had no work done to it which I don't understand. gunna order the multi meter tomorrow or buy one from somewhere. when Ichange the wiring loom tomorrow ill check the earths, as a friend told me it could be a dodgy earth. don't get why somedays its perfect some days its not and some it won't start

This may sound incredibly stupid at first, but bear with.

I had a GZ, and the wrong bolt was in the clutch lever. When I pulled in the clutch lever, sometimes it wouldn't push the switch in fully and the bike wouldn't start for love nor money. It took a while to diagnose. Once the correct bolt was in never had the problem again.

So might be something to quickly check and check the clutch switch pin too.

[Nick 50]

Have you managed to get anywhere with the bike?

Iv manged 209 miles now not had the problem which I dont understand at all, still waiting for it to stop working.

[_Chris_]

Just in case it comes back... there are a few 'safety' features on this bike that could play-up - check the switches for:

1 - The clutch lever must be fully in to start the bike

2 - The kick-stand must be fully up if the bike is in gear (if you put the kickstand down before going into neutral while parking the engine cuts out)

3 - Kill switch
