Hi guys need your opinion on a problem Im having with my wee bike. Ybr 125 keeps cutting out on me whilst moving..electrics stay on and it seems to want to kick back into life with afew twists of the throttle then just dies as I come to a stop. Any ideas ? Cheers guys be safe. Sam

My wr is being a pig to start cold,valve clearence fine, carb cleaned and set,new spark plug x2. I have read the factory manual cover to cover and no mention of the spark plug boot resistance,I'm getting 11k ohm readings and thinking its to high should be around 5 k IMO. Anyone know what it should be?

Hi, new poster here. I've been having some problems with my Yamaha XT125x. It is a 2009 and it has an arrow exhaust system. I've found recently that the bike will not idle/tick over very well at all, I'll put the choke on for a bit and leave the bike to warm up but when I come back and turn the choke off, the bike will slowly deteriorate down to about 1000rpm, and then to 800 and it will die on me. It even happens sometimes after I have been riding for a little while for example. If I get stuck at traffic lights, the bike will sometimes just die on me. The other issue I've been having recently is that when I'm riding along, I will change from 1st to 2nd, ride for …

if i was to fit a 70cc big bore kit to my yq50, would i need to upgrade anything else for it to work properly?

My bike has had the same spark plug in for over a year. I have decided to buy an iridium one. The prices vary from £6-£13. I have read that they're are a lot of fakes going about, how do you tell?

heylo folks, i have a rough idea of how to strap down a bike in a shipping crate and thought i'd double check by having a quick browse online but i get the impression that there are several views on the subject with no real clear definitive consensus. anyway, thought i'd narrow it down and find out if you good people have a system you prefer or can advise on. havent had a bum steer in here with my endevours to get my bike back to the UK so far! using a steel-framed skid which is forklift only (cant be suspended by straps) and i have plenty ratchet straps to spare.

Does anyone know what the part number is for the throttle needle or were i can order one ive checked ebay and they only have the 175 needle ive tried allen carbs and they need to know the part number and i dont have a clue what it is

I don't have a service manual yet... wondering if anyone can give me the specs on ignition timing / point gap? Also.. do timing marks exist or is a dial indicator required?

Hi Guys, did anyone ever noticed that the front cylinder exaust sounds very different from the rear cylinder? Also while adjusting the intake valves clearance , I forgot to take out the sparks and noticed that the compression (when moving the crankshaft) was escaping trough the timing sprocket case is this normal? Should I be able to move the camshaft without removing the plugs? Sorry for these questions. but I'm not used to 4 stroke engines.

Help please, I have a fzs1000 I went out sunday with no issues, then yesterday I did about 100 miles stopped in a layby for a fag then the bike wouldn't start it just clicked on the starter, is it a battery issue or anything else causing the problem, I did have a meta alarm fitted but that decided to immobilise the bike a month ago so had it removed, the bike had been fine till yesterday

Hi i have a XJ6 2013 model, now i got i crack in the plastic case under the seat and i cant seem to find the name of that part or anywhere to order it. Please if anyone can give me a name on the part i can search for it, or if you know someone selling it online or something pleace let me know the website so i can order it Its the plastic case on one side, like in the picture that has a crack in it. Badly need hlpe with this.

so i have slowly been working in this rxs. did a top end rebuild new hear barrel and piston, still dosent seem to run as well as it should. seems low on power and a bit lumpy, then we have oassional bogging down. its sorn so i ant take it for a good ride. and how it is put together right now its not fit for the road yet.. thought id make a you tube vid of it see hat you guys think http://www.youtube.com/watch?v=NFTWUeWWlq4&feature=youtu.be

I have a power commander 5 installed on my bike but have no idea what it does and how it works can anyone shed some light please.

Ive just fitted 4 new indicators they come with there own relay they all work but they all flash at once insted of just one side any ideas?

One of my silencers has a hole in it . Does anyone know where I can get a silencer for a 1982 TR1. I've tried all the usual websites and can get fittings and fixings for the exhaust but can't find the silencer. Please, someone help me

does anyone know at all how you can get a idea if a bottome end of the engine is ok like the clutch and gears when the engine is not in the bike or running , it does turn freely and the piston goes up and down and it seems to engage gears and rotate is there a procedure for checking it at all or is it a case of putting it together and then testing it ,

I have purchased some crash bobbins from a company in Italy. They fit directly to the Engine one replaces the brake fluid bolt and the other (gear side) is mounted on a tab in front of the crank case. I am really not sure that these are going to help or worse still transfer the force directly to the engine casing. If anyone has any experience of this design I would appreciate your advice.

hiya guys, can anyone help me diagnose the fauly with my yamaha aerox yq50.. i was out one day riding it no problem then suddenyl it cut out. after about 10 minutes of sittin at the roadside like a lost spanner it started again. ran for a bit and then cut out, it done this about 5/6 time and now it just wont start. anybody have a idea of what it could be? carb is gettin fuel and checked and changed spark plug. could you point me in direction of what the most likely roblem could be and how to go about fixing it? any replies are much apreciated

I have a few questions and would appreciate some advice from someone that can point me in the correct direction. The Bikes the police and ambulance service use have a swich fitted wich allows the bike to keep running whilst the key is removed, for the purpose of powering the lights that they leave on, as soon as the bike is dropped into gear it automatically kills the bike. my questions are; Can you buy premade kits, if so what are they called? if not is it possible to make it happen yourself, possibly using a transistor from the neutral light? I only have a basic knowlege on electrics/electronics and would appreciate any help. thanks, kyle.

hi im a bit confused with what spak plug to put in my bike it has in it now cr6hsa which we think has been in their since new and it need's replacing. i was told that their are a number of spark plugs avalible for the ybr for example the one i have in it now is apparently meant for slow inner city driving (or its better at it), but i was told their is another spark plug that is better for higher speeds e.g. A roads. from what i could find on the internet it pointed to the NGK C7HSA for this so i went and brought it but now it comes to putting it in the bike and i am worried that it will cause it damage. if annyone could clear this up it would be greatly appreciated. …
