Yamaha YBR125 new owner/rider

[seanz]

Hello all!

 

Total new comer to bikes here. I've just done the CBT and picked up a 2006 YBR 125 to learn on. (Same as the one I sat the CBT on, has carb and old) it's been sat in a garage for a few years unused. So it'll need to be completely cleaned and new rubbers here and there. But aside from that...

 

It's not working (no spark, no manual) and that's why I've found myself here. I've got no reading on the alternator coil? 200k ohm range with o.oo on the metres screen? 

 

Can anyone recommend a thread for this issue? Since this must be a well covered subject on here. Or simply a list of what to look for on my new ride. 

 

Many thanks in advance and happy to be here! Look forward to hearing from you all and trawling through. Because of the current time I'll have to do that tomorrow now though. I'll be driving to Bristol tomorrow, so slow to reply. On to legoland the day after with the kids. Shall answer in the evenings most likely. (It's my less handsome brother in the photo )

Hi Sean, welcome to the forum. 

First place to start is the kill switch next to the throttle, make sure it's in the run position. 

You're probably going to need a new battery, any fuel left in the tank will need to be drained and replaced with fresh. 

Also, the carb's will need to be removed so you can clean the jets. 

What a great experience for a new rider, you'll really get to know your bike.

Welcome to amazing the world of two wheels. 

Have fun.

And fresh oil and filter for the engine would be a nice treat for it.

The YBR is a popular bike so you'll probably find videos on YouTube for all these jobs. It's a great bike too... Good choice.

Hello  and welcome Sean!

 

nothing wrong with the choice of bike and you didnt get a chinese bike (even modern ones are terrible) . 

 

been up and down capacity and technology over years, currently on a late carb bike again (suzuki gsf650s).

dont be down hearted on carbs, when its clean and set up the fuelling will be so smooth and brilliant that only the very best and expensive modern FI systems can match at great cost. the only faff is the  "choke" but you get used to that.

FI have to get around ever tighter emissions bs, if the closed loop circuit design isnt done exemplary which is difficult and leads to jerky throttle when opening at low revs which carbs shouldn't suffer from.

 

the other thing which the bike might run on E10, but with its age of its rubber components "an advice" would be gentler on rubbers to run it or if your gonna leave it in for long durations with E5, unless youve got a future plan on changing the rubbers that the fuel will be in contact with as a maintenance thing while in your care?

 

there are a few members on here that are quite electric minded if its really troublesome.

other basics are the ignition barrel, ignition & side stand switch, fuses, relays, battery terminals, electrical points and ground wires.

check over and narrow it down for us all for further help.

Cheers all, Ridewithstyles yes, I've got a few bits to bell through. Found a wiring diagram online for the carb model. However it didn't come with a side stand? So one less thing to check. I'll get on it over the weekend and check all the above.

no side stand? or do you mean centre stand?

Sorry for late reply. Yes, the kick stand was removed or not there when I bought. 

[RideWithStyles]

Hmmmm. worring.

should still have the sensor (a metal moving flat pin) that the side stand uses, other wise the bike will not start unless its been bodged or by passed for using it track side?
