I have an XVS 125 (54 plate, 6.5k). I was out riding the other week and she started to lose power when doing 50mph. It only lasted for a second like the brake was on, and then continued as normal. This repeated a couple of times during the journey. I have replaced the oil and filter and put new plugs in to see if it helped. The old plugs looked like originals and appeared black at the ends, one was slightly wet on the thread. On the way to work, she did the same thing again when I got her in to 5th gear. It was an extreme downpour at the time and I initially thought this may have been contributing to the problem and the engine was not warmed properly. However, when I pu…

Last night she started fine but was still bogging when I applied throttle in neutral. So since she is still bogging and having gone through various things, I decided to clean out the carb today. I removed the seat and speedo, but when I came to remove the air filter, I noticed there was a lot of oil in it (she had previously had too much in it to start with). I recently changed the oil, plugs and oil filter but had forgotten to check the air filter. So I've now clean out the excessive oil, cleaned the filter and put the unit back together. I reconnected the small hose and silencer and fitted the air filter unit back onto the bike. I reconnected the speedo, two sock…

Hi all again, yet another question I will buy a manual at some point I promise. I was wondering about the tension of my cam chain. Reason for this is I have noticed that it seems a bit noisy( the engine I mean) when I have her out a run. Now I know it could be a number of things I.e valve clearance but as I have never done this myself before I thought I would check the tension on the cam chain I gather this does not self adjust as I can see a bolt with a lock nut on the side on the tension adjust unit so can anybody give me a run down on how to check/adjust my cam chain? Sorry if you's lot think I'm a pain in the ass but I bought this bike with the intension …

So .. as some of you may be aware I aquired a little SR125 for £120 (lol) as a non runner that had been stood for 6 months Anyhow I managed to get him running on Thursday, enough to ride him to my local car mechanic and show him, seeing as I had been pestering him all day for advice... When I got him to the garage, turned him off and left him for about 15 mins to chat.. went to restart and he struggled to fire up..! Eventually got him going again and drove it round the ind estate to try and get the squeak out of the rear brakes. So JOY! I was happy, went home and booked him in for an MOT just to see what it would need... Went to start him yesterday…

Hi I'm struggling to sort this problem. The break light is on constantly- (unless I remove the earth spade from behind it, then the rear light filament comes on.) I've removed the break switch and the light stays on. Ive tested the switch and it appears to be working. But it's disconnect to count it out. Can anyone suggest anything- is it a case of checking wiring?

I would like to fit a larger headlight to my 650 Dragstar as the stock item looks a bit too small. I don't really want to have to make any modifications and so a straight swap would be ideal. Does anyone have any idea of a larger headlight that would fit?

its driving me nuts!! morning all... i've had this bike a yr or so put new camchain on it as it came without on, i think it must of broke on the last owner.. anyway did that ,it could do with some new guide rails.. i have been useing it this last 2 weeks on and off.. but it wont start i have to unscrew the carb tip some petrol in it then it will start, the choke is'nt working right, it dont work unless you tug it from the carb end... the idle is up and down... we did a oil change last weekend and tons of metel fileings came out with the oil filter and the strainer at the bottom of the engine....we have stripped and cleaned the carb twice...any ideas??

we are restoring our rd400.. will the fork stantions fit from a lc?.. we want to put twin discs on the front....

ive just changed the entire engine but not the carb and the new engine can barely keep itself running because the idle is to low. Ive checked the valves and read a lot online and i cant figure it out please help

Hi Guys, Looking for some help with daughter's DT50MX - stolen and recovered tore all the dash and clocks off and twisted wires together. Bought a donor bike for bits with spare ignition and clocks. (the donor bike has points) Refitted and electrics working but no spark - it is a CDI model. Is there any way to test CDI for faults and would shorting all 4 ignition wires together cause this to burn out? Any help gratefully received. Steve

First post, first motorbike. Having ridden peds for about 8 years, I decided to up my game in preparation for doing my full test in a year or two. I bought a good condition yamaha rsx100 which a friend of mine who knows more about mechanics than me checked over. It seems to be in great condition, both mechanically and body wise. However, the one issue it did have was the kickstart lever. The ring of the lever has worn down and thus needs replacing. Being a complete noob. I bought a kickstart lever for an rxs100, believing the parts to be interchangeable. I appear to be wrong. The lever arrived, different shape, and the connector ring is too large to fit the…

Hi all, I have just recently bought a xj6n I'm new to biking and wanted to get some information on when or how long I need to lube my chain? If you can explain I will appreciate it, Thanks

How do u set the timeing chain and cog on the engine in a xvs 125

So im doin about 100-110 kph and it starts to drop power so i check on line and ask few bike owners they say carb or electrical so i get tank and all off carb and rubber y leg thingy ( which has few cracks ) then i decid il service it while im at it so drain oil pull out filter no bother like, then go to take out plugs (engines cold and iv gave a squirk of wd40) i get socket on it and f@#k its tight get about 2 full turns then pop plug snaps ( words were invented at this point ) so i start thinking wat am i goin do so off i take the head get a easy out into whats left of the plug and get i…

Hi guys, Just a quick one. I have noticed a clicking coming from the front of the bike which speeds up when I speed up. Now the ticking goes away when i apply a slight pressure to the front brake (not enough to slow the bike down) and therefore, in my knowledgeable opinion (which is just short of absolutely nothing) i'm thinking something to do with the brakes . Any help would be appreciated ps its a Yamaha XVS650 Dragstar ta!

Okay well i sold my old bike due to having an electrical problem that i gave up on trying to solve and now i have my eyes set on a mint 2001 dt125r BUT it needs all the lights wiring, all the wires are there they just need connecting apparently and i know for a fact that this would totally do my head in so i am just wondering how hard it actually is? Thanks all!

Hi all i posted his elsewhere on the site but think i stuck it in the wrong area. Thing is i have a xj600 pre and was wanting to know about putting wider tyres on the bike. I know there is a rule not to mess wiht this but im not talking 180 rear here. I was thinking of maybe either 120 or 130 rear and maybe a 100 front. Reason for this is i feel its a bit to prone to jumping into road rutts and you get pulled about a fair bit. Also would like a more rounded profile. Another factor is this is the first bike i have owned with such skinny tyres and i also ride a gsxr 600 so im not want to go risking anything. Dont get me wrong i love the bike and i seem to be using …
