Yamaha Workshop

Hi everyone As I state in my greeting message I am totally new to biking I own a aerox 100cc 2-stroke scooter and need help with a couple of things please any help would be greatly appreciated. 1. When should I use the manual choke? 2. When I bought it I was informed that the under seat storage lock was jammed is this easy to fix/ could I do it myself or should I take it to a garage? Thanks

All sorted. Can delete this thread if need be. Cheers

Now, this is likely to be a very noob question, but i am a tad confused. I want to get a brighter light for my 07 ybr, so have been looking into the options Everywhere I look i have managed to work out that the headlight for the bike is a H4. http://www.autobulbsdirect.co.uk/yamaha-ybr-125--2007-07 So i went along to halfords and purchased one of these. http://www.halfords.com/motoring/bulbs-wiper-blades-batteries/bulbs/halfords-extreme-brilliance-hbu472eb-h4-car-bulb-x-1 However, When i came to replacing the bulb, it had a very different fitting: http://www.halfords.com/motoring/motorcycling/motorcycle-parts/halfords-bike-it-motorcycle-bulb-hmb395-12v-3…

Been meaning to sort out the rear light and no indicators working. Neutral light and headlight working fine so I`m wondering about flasher unit for indicators and the loom to tailight looks dodgy (hanging under rear mudguard perilously close to the tyre. Any ideas how to go about sorting it out..electrics not my cup of tea.

Does anyone have any recommendations on installing usb to the YBR (or indeed any bike); any particular make that you would point me at? Any issues with connecting direct to battery or is it better to find something switched to ignition (headlight)? In short I'm looking to have USB power and a reasonably waterproof mount for an iphone 5s - mainly i want to use it for satnav but while I'm here i might as well ask for opinions on bluetooth headsets for answering the phone. At the moment I have pretty much taken the view that while I am riding i will not be answering the phone at all, but it would certainly be interesting to hear opinions from more experienced riders. …

howdy folks, does anyone know if you can fit the fork covers/shrouds from a vstar classic onto the forks of a vstar custom without have to change actual forks & trees, etc? Grave

Hi stupid question but which way round do they go, does the silver spring round the seal face up/outside the fork or down/inside the fork. New seals were fitted but still leaking and hence failed its mot, 1st mot since owning it. Stanchions are fine. Not sure if they were put in the wrong way round or maybe not driven in correctly. Cheers

Bit of late summer maintenance work today, checking over stuff as you do. Plugs 1 and 4 look to be running a little rich, 2 and 3 are fine, bikes running good If my understanding is correct, is this the air adjustment screw? If it is (and both heads look mullered), is it in or out to weaken? Thanks

Has any body used Powerhouse in Sheffield for work and if so are they any good ? Has anybody had problems with seized tickover adjuster and any ideas how to free them ? While I am on, how easy is it to remove spyball alarms ? That will do for now thanks. Mike

So, I've got this bike which I've left sitting out in the rain for years. It's in a sorry state. I've been out and given it a wash this morning and had a look at what needs doing, and cosmetically I've got the following list of jobs: Replace chain and sprockets - rusted to a lovely autumnal colour - needs binned and replaced Replace exhaust - matches the chain in rustiness. A replacement exhaust which isn't chrome would be perfect. Decide what to do about the wheels - the rims have rusty patches and would need some serious work to restore them, but cost of new wheels?! Would love to get replacement wheels which aren't finished with chrome. Front disc looks a tiny bit…

What do I need to do to stop my bike running lean and a bit sluggish after fitting a full arrow exhaust .I'm relatively new to bikes so help would be appreciated.

Hello im having a little trouble with my rectifier, Most likely my bodged up wiring lol Basically im here to ask on the Dtr125 loom you have 3 power wires coming from stator (Am i wrong ?) Yellow/Red, Black and White Yellow/Red for the lights after rectification White for i assume just general power (like battery charing) and this is the one im confused about the Black. Why is the black connected to a live ? Isnt in an earth ? Im having problems with my lights. The bulbs keep going pop Normally i wouldnt ask about the black but what ive done is put the DT125re engine to a DTr125 loom and have done as follows (all 3 power cables on DT125re en…

Well tried my RD250E (1979) for the first time to day - a bit of a shake down Well the good news is it is still quick and smells great, I forgot how Revvie they were and how much you need to be in the power band, suprised at how easy the front wheel gets lite Gear changes felt a little notchy but will adjust the clutch later and see if it improves to be fair used to ride them in trainers back then but know its boots all the way. I would appreciate your thoughts on a couple of things, firstly the brakes feel rubbish plenty of pressure from the lever but didnt stop very quick. Maybe I am just used to modern twin disc fronts or they need bedding in for a while - …

Hi all i have been restoring a Honda Mt5 moped for my son. on rebuilding the bike i made some pre mix fuel as i have had the oil pump off.i think i put to much oil in this. the bike started and ran ok for a few minuets then died. the oil pump had primed and was pumping into the manifold so far to much oil was going in to the mixture, i removed the plug which was fouled and have since drained the carb and fuel tank and refiled the tank with fresh fuel,the bike will not start. my question is could the oil in the fuel block jets in the carb as there does not seem to be fuel getting to the chamber as the plug seems dry. any advice would be fantastic cheers nigel

ok so time to start using the real 2 stroke oil res. filled it up. started the bike let it tik over on idle for a bit.. More smoke than you can shake a stick at.. My diagnosis? To much oil getting thru.. my question? how do i adjust it on this stupid thing?

Hi I haven't had my dragstar for long but when I got it home I noticed underneath was slightly oily on the left hand side of the bike kinda near the side stand along the frame and surrounding areas. Cleaned it all down and had my first run on it today went about 20 miles or so, had a look under and again was fairly oily, doesn't seem to be the sump plug but appears to be coming from up higher in that area and spreading it around the lower areas. Can't quite see very well as the bikes too low to the ground. Can anyone help with ideas as to what it could be ?

Hi all I'm looking to go about installing my 16 apes onto my dragstar. I've never worked on bikes before I bought this so if I ask lots of questions you know why haha I've got the bars and new grips. Now is there anyone that can do the work around the Cambridgeshire, bedfordshire area? I can get my cables extended if I take them off and get them sent away, how easy is it to remove the brake, clutch and throttle cables ? Next is the electrical side of things. Now would I be able to do the electrics myself ? Bare in mind I'm not quite experienced in electrics. Ideally if there's somone in my local area which could do the lot then that would be perfect

the rear cyl. does not fire, front fires fine, rear coil tested good, any suggestions?

Hi, ive got a 1990 yamaha dtr which im gonna be rebuilding but the engine thats currently on the bike is a 2006 which isnt wired in at all so i was wondering if it'll pay me to get a 2000-2003 engine to go on as i cant find any 1990 engines about at all, i do have the origanl engine but it was droped n apart of the engine casing and it'll need a whole rebuild n new intenals but i do have a wiring loom for the 2006 engine but i'll just have to wire everything in on the bike, im just kinda lost on what im gonna do so i thought i'd come on here n ask you guys for some advice. thanks in advance

Can anyone explain the difference between adjusting a throttle needle up/down versus the airscrew on the carb? The way I understand is they are both affecting air fuel ratio.
