    Hi Guys Been away for awhile as bills have to be paid. Bike running lousy..dies at high revs and wont idle. Removed carb today, stripped everything, soaked in boiling water, sprayed carb cleaner and blew all out with compressed air. Refitted carb but she`s leaking fuel badly out overflow and still running lousy...seems to get better with choke out. Could this be floats or maybe needle and seat?

    I have a 2009 YBR125, which I have ridden for the last 2 years or so. Yesterday I had a bike to ground interface, which resulted in a need for a replacement front mudguard (easy and cheap) and instrument console - the back casing is mashed and the glass on the speedo has broken. Now... BrooksBarns have a speedo for a 2005/6 YBR on their site for about £34. Looking on the Yamaha parts finder it would appear that some of the internals have different part codes than for the 2007-2009 model, but are they still compatible? I have seen kph ones on fleabay for around £45 but I would rather have one that is in mph for obvious reasons. Unfortunately from what I can see the p…

    Bike going great from 5000rpm upwards..below that its sputtering and not idling. Wondering now about the oil/fuel mixture. Its running on the autolube system and someone suggested it may be drowning in oil..so he suggested a hotter plug. I`ve noticed in the manual the oil delivery can be set so wondering if I should fiddle with it.

    picked/nicked this from the 2 stroke forum. never heard of it before, but you can dye plastics. there's not loads of colours but if you want to be "back in black" ( see what i did there?) worth doing for £6

    Hi Guys. As it turned out the ignition coils where both all right . I got them re tested. Left the bike into a proper bike shop while I was away. It turned out to be the throttle position sensor and the CDI Unit. The shop is testing a spare CDI Unit tomorrow to confirm if mine is fecked. Will keep you Posted on the outcome Mel.

    Tail light was working all along then yesterday suddenly nothing..brake light still worked. Swore a bit as I wanted to get the bike MOT`d today. Changed the bulb and still same story. Stripped off bracket to check wiring and everything looked ok. Here`s the kicker..so swopped the 3 wires around going into tail light bracket and now it works. I`m confused??? Anyway it got the bike thru the test and she`s 100% road legal.

    Hi folks, first of what may be many questions as I try to resurrect my little imported 175. I have tried Yambits, Wemoto and CMS to no avail for the air filter element. I have the cage, if it is Indeed the right cage, but the filter itself was just some old sponge stuffed in the air box. Anyone know what would be compatible? The box is vaguely diamond shaped when looking in, and maybe 4 inches deep. Cheers Mark
