My big yellow lemon (NSR125R)

[c-m]

Onto my 3rd 125 now (theory booked for next week) after the KH was stolen and the NS was hit by a take-away driver. I fancied an easy-ish project, so ended up buying the big yellow leomon below:

couldn't take a decent pic in such a confined area.

The guy told me that the starter is gone and it needs a new wing mirror, fairing bolts and bulbs.

He bump started the bike, which sounded like a mosquito on steriods (my NS had a much better note).

Now however I can't seem to start the thing. I've sprinted along with with it but no luck yet.

more importantly however I noticed something perculiar about the forks.

Notice anything wrong here?

Looking under the bike I have also noticed this

what is this wire for and any ideas why it would be cut?

I would be guessing that wire is the reason you cant start the bike. When you turn the ignition on are you gettin lights and horn? When did the bike start "not starting"? Did you ride it home ok? The first thing you would want to do is solder that wire back, and then see how she goes from there.

the ignition is fine.

The guy told me the starter motor was dead, cheapest i've seen is about £79.99

At present when I press the starter button I hear a little click and that is it.

That little click you get is probably the starter solanoid engaging, I cant be 100% sure but that wire thats been cut looks awfy like the starter motor....

I can't tell what's what in the photo, but could it be the side stand cut out switch?

[biker_king]

i have the same bike as this, its the italian one rite?
the forks look the same as mine. connect that wire and see if she turns over if not the starter has gon look one ebay for a new one or iff you close by iv got a spare one you can have, also it is a good idea to change the spark plug on thies bikes.

[c-m]

I tried bump starting it again but to no avail. The guy did it right in front of me yesterday first time, not sure why I can't do it.

Anyway, I turned the ignition on and held those wires together, I can hear a spinning as if the starter motor is doing something, but it doesn't start the bike.

sounds like the starter gear ,remove the alternator cover (on the left hand side of engine), their is a gear with teeth on it that is supposed to engage on the teeth on the fly wheel, remove the gear and free it up .
also have you maid shure the fuel tap and kill switch are on ect.

[Aikman666]

To be honest im not sure if thats where it is, the one on my CBR sits ontop of the engine, the one on my RX's sister bike (The RS) would have sat underneath, and if theres a whirring noise coming from it, its more than likely. To be honest it sounds like the teeth on the gear that engages the starter motor have been stripped (hense the whirring). Do as biker_king says, then come back and tell us (or show us) what you find.

Also what method are you using to bump it?

I have removed the alternator cover and found a big circular magnet attached to a big cog.

The thing at the bottom is indeed the starter motor, I can see it spining around. I cant see anyway it would ever engage this big cog though.

TO bump it, i'm running along, jumping on it and dropping into either 1st or 2nd and letting the clutch out.

Solder that live wire back together as a start.

Then turn the bike over whilst checking the battery voltage. Make sure it's ok.

If it doesn't fire with good turnover/good battery voltage. Check Spark from plug and fuel.

And remember to try starting it with choke ON

Surely your lights work as they'll run off the battery, which may be too dead to start the bike, and them wires look like the starter motor had the wires cut, hence it don't work. The forks look fine, if your referring to lack of a nut on the end of the bolt, I'd say the nut was built in the fork, leaving the long bolt to just go through and nip it up.

For an Italian one it looks neat, I knew another lad with one Til he blew his engine about a month ago..

What's wrong with the NS?

i'll be able to do more over the weekend. go some more pics to get up, but left my usb at work.

The NS has whole list of things wrong with it, they are listed in another thread. its a cat c write off. Sold it on ebay yesterday for £140.

As for the NSR It looks ok initially but I think its been dropped heavily or in a bit of an accident. It was orginally black, though the spray job is very good. The fairings are damaged and the frame has been painted black, gold is the orginal colour right?

my plan is to first get it started and running, then carry out basic servicing, then tidy the thing up and get it on the road by the end of the month.

£140? Do I spy a seat convertor?

Yeah gold or silver, do a HPI and see what it says, an accident aint too bad as long as the repairs are up to scratch.

Ok so i opened the left hand side engine cover and found:

https://www.eastcoastlacrosse.co.uk/carl/nsr/Image543.jpg

I can see the starter motor underneath that large magnetic cog thingy

https://www.eastcoastlacrosse.co.uk/carl/nsr/Image544.jpg

the starter motor spins, but doesn't make contact with that cog, should it?

P.S can someone confirm that there doesn't need to be a nut on that left had fork?

Took out the plug last night too, to my supprise It was a BR7 surely that is way out.

I put in the Denso plug from my NS and and very nearly got it started by bumping it. I'm sure I have a BR9ES around somewhere, so i'll give that a try tonight.

Didn't think that needed saying Sure it's not an F? I'd see if alains knows about the forks for confirmation. Yes, the starter motor should be contacting it's coggy type bits.

whats to confirm? the left hand fork is threaded and theres a pinch bolt on the right hand side, im sat here now looking at the haynes manual for that bike (sold the bike 2 weeks ago) and there is no nut on the fork.

and if your motor is spinning but not engaging then strip it clean it and replace the brushes then try it

i've taken the starter out, it spins quite happily on its own, but when it engages the gear it doesn't move at all.

I still can't bump start the thing. It really wants to go and almost gets there but then dies. I think its because I can't disengage the clutch at all. If i put the bike into gear and pull the clutch I can hardly push it.

Check clutch lever adjustment, then cable is fine, then where it goes to the clutch basket.

Failing that, take the clutch casing off(undo all bolts and drain any fluids-but there shouldn't be any) then check it's sat right and not jammed/caught etc.

Also, check your choke lever/cable/the bit that goes in the carb is ok. Then report back.

No worries. Changed the plug, couldn't get my plug spanner in so ended ujp taking all the fairing and tank off, then realised that, that did offer any access to it at all. Used an adjustable spanner in the end.

I've taken the starter motor out, currently sitting my kitchen work surface. It looks ok, but it just doesn't seem to have enough power to spin the flywheel. After a new one ASAP.

Rode the bike up and down my alley way. The front brake is aweful, though the back is nice. The guy told me had recently put new pads on the front too
