From your description it sounds like some form of fuel starvation. Simple things first. Check the fuel cap of the tank to ensure the breather is not blocked/partially blocked. or it may have a rubber gasket which has become 'stuck' If its blocked as the fuel is used, a vacuum is created above the fuel which will in turn stop the fuel from leaving the tank. As you throttle up, you use more fuel and the vacuum is created. The throttle doesn't respond (like what you face when the fuel tank goes dry). May be helpful?

You may of course have more then one problem The Dash probably uses a common earth but the headlight issue sounds a little different. I'm not sure it would be a common earth problem as you say the main beam is ok, you see the light bulb dip and beam filaments will share the same earth wire. If the Main beam is unaffected then I would think its the Dip live feed wire or indeed the bulb itself. Might just be a dirty contact on the bulb. Check the bulb first. Then look for trouble.....

Nice work DT that looks like a huge piece of kit!!! I've got one of those small Maplin Ultrasonic cleaner, I say small, a carb fits inside, do it one side first then turn it over. I do find the more parts you put in, they don't clean up so well as they do when in on their own. I'm sure its down to 'interference' of the ultrasonic waves, a bit like throwing two stones into different areas of a pond and where the ripples meet the waves are dispersed. Experimenting with various solutions and temperatures, I found using just boiled water best and despite trying detergents etc I was quite impressed with the organic seaweed based cleaner it came with which was most effective for aluminium and brass.

Here's me in 1978 in my home town of Brighton on my first ever motorbike, all right........... scooter! I never purchased it to be a mod, I bought it for £12 because it was all i could afford and It was a stepping stone to get on the road. Other friends had various colours of FS1E's, a Vespa, Puch maxi, Honda 'Hairdryer' SS50, a Yamaha RD250 in blue and the best of all was the FANTIC Chopper! Remember back then the Limit was 250cc not 125cc. This was a 1961 175cc Li series 2 which i purchased a few years earlier in 1975 from a friends brother from 'around the corner' he'd owned it through the 60's in Brighton. It was therefore a genuine mod bike, purchased I might add..... BEFORE the 70's mod revival. This blue one went to the great scrapyard in the sky and It appears to be still registered to me on the DVLA website, not sure what happened there as I sent back the log book saying it was scrapped! I did purchase a bright orange one as a replacement for about £75 (loads of money back then!!) I put on loads of mirrors and flyscreen and then Quadrophenia came out and I sold it for hundreds of pounds!! can't remember how much exactly but I made a mint........and have never managed to make any money thereafter!!! Just Look at those Flares!

It's a digital display then, which is flashing the word "OIL" ?

Every now and then Blackhat likes to pull my leg on my ownership of a Honda, so when he said i'd got a fetish....... I thought I'd get in there first! ( I notice I replied to blackhat at the same time as DT50 posted, so mine got out of sequence )

and I've got a Honda too!

DT50's suggestion might be right afterall..... http://www.ebay.co.uk/itm/Harley-Davidson-Motorcycle-Black-Leather-Boots-Women-High-Heels-4-Zip-Up-Sz-9-5/131178333865?_trksid=p2050601.c100103.m2451&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20140211150826%26meid%3D6576927737016595693%26pid%3D100103%26prg%3D20140211150826%26rkt%3D4%26clkid%3D6576930821238577852&_qi=RTM1790005#ht_253wt_922 how about those for size!!, should be able to touch the floor all right..................won't be able to ride the bike though!!!

Jim I assume she's the pillion yes? Is the problem the low footpeg position ? if thats the case i wonder if theres any footpeg modifications, raise them up onto the frame/swinging arm I guess it will depend on what year the bike is..... Or is it she's perched up in the air and doesn't like it?............then add a sidecar!!

You don't have to change your bike....you could change your partner for a long legged one!! http://www.dailymail.co.uk/news/article-2252626/Worlds-tallest-teen-girl-towers-boyfriend-enjoy-romantic-walk-Brazilian-beach.html

No idea Drewpy, never been there either! I was just letting Nursejim know he was in good company.

Hi Jim ,another Welcome......... I've never been to Wrexham! However, I have just clocked up 35 years Nursing!

Where did he go?

It may be worth noting that car battey chargers and boosters are not designed for 12v motorbike batteries.

Have you found the same relay (as your link) on YOUR bike and confirmed its running the indicators? Ie unplug the relay and see what effect it has on the indicators and that it has 4 pins! The reason i ask is I've done a search on ebay for ybr125 relay and I found there are white 4 pin ones which look identical to your replacement, but its not for the indicator......... http://www.ebay.co.uk/itm/YAMAHA-YBR-125-CUSTOM-2010-Multi-Function-Relay-/291078877961?pt=UK_Motorcycle_Parts_13&hash=item43c5a73309#ht_2186wt_966 http://www.ebay.co.uk/itm/YAMAHA-YBR-125-57-STARTER-RELAY-3D9-00-ACA12115-M14-/251435929052?pt=UK_Motorcycle_Parts_13&hash=item3a8abfcddc#ht_2340wt_758 This link shows both the 4 pin white one and a 2 pin indicator relay in the same photo http://www.ebay.co.uk/itm/YAMAHA-YBR-125-CUSTOM-JOB-LOT-RELAYS-SENSORS-ETC-TILT-FLASHER-YBR125-C-2012-/281057891475?pt=UK_Motorcycle_Parts_13&hash=item41705b1493#ht_1297wt_758 and so does this link http://www.ebay.co.uk/itm/YAMAHA-YBR-125-2007-ERA-VARIOUS-RELAYS-/230953439326?pt=UK_Motorcycle_Parts_13&hash=item35c5e5d05e#ht_44wt_723 Heres a link for a YBR125 2006 model, and its two pin http://www.ebay.co.uk/itm/Yamaha-YBR-125-ED-2006-125-CC-Indicator-Relay-/390559761317?pt=UK_Motorcycle_Parts_13&hash=item5aef2d03a5#ht_1396wt_966 You see I was wondering why an indicator relay would be 20watts........... Can you post a photo of both of them? I'm intrigued why there should be two!.......unless a previous owner has ADDED them! now theres a thought! Your replacement link has 4 pins so if you have two indentical relays you will have 8 pins. Can you confirm that if there are two and that ALL 8 pins are in use? or are they just using 2 of the 4 pins of each relay? Or have you not taken the plug off ?

Thanks Welshwan, not sure why it didn't work for me Good job it wasn't a biker cam eh?

Uploaded today! http://youtube/eLZjq2vxD3Q embedded ...but doesn't show here!.....must have done something wrong!

and now its in the UK...........

Bippo's right , however, looking the chain over and oiling it is no substitute for removal of the chain and inspection. A stiff link is just that and cannot be assessed by a good look over with the chain in situ, you need to take it off. You won't be able to tell with the chain on. Plus with the chain off you can run the motor and the bike won't go anywhere!! however, if its clicking away then the fault lies in the motor side, if all is ok then its the chain or rear wheel. A process of elimination. I had this very similar problem on a chain years ago , clicking on acceleration, it was a stiff link which with the chain off, holding the chain up on each link I discovered the two solid links which were the ones which didn't move.

That sounds like a stiff link on the chain to me. You may find a pair of links which are rusted together, coasting (I assume you mean clutch in) disengages the chain. As the two chain links are seized they don't sit inside the teeth of the sprocket and 'ride' higher and clunk as they come off the sprocket. The faster you go the clicking gets more rapid. The same thing happens on a bicycle chain. My moneys on the chain, needs maintenance or replacement...

Glad to hear you sorted it, Why don't you change the title of this thread, you can edit your own post to "YBR125 Indicator fault - solved" and perhaps you could mention where you located the main fuse on the bike for others benefit should they have a YBR125 with the same problem. Every little helps!

Owners advice: Easily obtainable spares. Lots of used spares available. Lots of new genuine/ pattern parts available Some genuine parts are NOT available....but can be sourced from any combination of the above!! Perishable parts DON'T last forever! You will need to keep an eye on some of those, don't expect a 30 year old tyre to be reliable or trustworthy!! Cables need attention, chains wear if not maintained, Runs on petrol and oil, don't forget either! Easy to work on Reliable Can develop problems ALL easily solved with maintenance, attention and/or replacement Robust. lightweight, (can be an issue in gale force winds I won't ride mine in beaufort 8 plus) Good on and off road. Brakes work fine, no need to modify, you're NOT riding a rocket!! Electrics:- lights and running are all reliable however,light/battery can be modified to 12v (don't expect a light show though!) Engine: 2 stroke....need i say more? Has a good following on this website, lots of support. Bike gets dirty if you use it! Bike stays spotless if you don't Have I forgotten anything?

Damm well hit a pot hole on the ride home last night!! took out my rear light bulb!!! saw the 'light go out' on the dashboard! Not to worry......turned on the emergency bicycle light LED and rode home! Put a new bulb in this morning and all working again. Nice to know it all works, not just in theory! I'm a happy chappy!

Not that it will resolve the blowing of the bulbs, but this may be of some benefit to you a cheap effective means of monitoring the situation............. Plus when i had the same problem I also fitted a bicycle LED at the back as a "get me home solution" in case the bulb did blow again. I've actually used it for one night in 2013. Got me home 'legally' showing a red light at the back until i could put a new bulb in at home.

To get at the bulb Blackhat offered you a solution in the 4th post.. Once the screw is undone either prise the rim as suggested or you may need to turn the headlamp anticlockwise by hand to 'unlock it'. It should become apparent once you've located the screw........
