    Hi there. I went to start up my ybr today and i noticed that the engine light flashed 3 times slowly then 8 times faster then repeated this fashion. I was wondering if there are any error code lists for a ybr125 08 or any other bike with same ecu? Thanks in advance.

    Hi there, I bought an old (1982) XJ750 a few months back, which I have been fixing up. She has got nearly 80000km on the clock. Currently I have problems with the way she is running: She starts ok, idles a little unevenly, but rides away ok. As she warms up, literally after 2 or 3km, she develops a "flat spot" at lowish revs (2000 to 2500 rpm). This gets worse and worse as she warms up, till (after 8 or 9km) I have very little power at anything under 3000 to 35000rpm, making slow riding almost impossible. She feels really flat as I try and accelerate, and then a surge of power as the revs gets over 3000rpm. She sounds fine at higher revs. And if I stall her I can…

    Hello there, first time poster. I'm looking at purchasing an xs250 as a project, it has a blown motor. The bike in question is an '86 XS250 RK, engine number 17E-105551. I've managed to find a replacement engine that looks to be in decent condition, althought it looks the same, the owner is not certain of the year or model of XS250 it came from. The Engine number on it is 19Y-000901. I was hoping someone here would be able to help me determine if it would fit from those engine numbers? If not, does anyone know of the development history of the xs? Was there a point where they changed the frame or engine? Thanks in advance.

    I posted last week about the problem with the exhuast clamp bolts rounding off. Well i successfully got them out. However, I cant get a new bolt into the holes. I have tried re-tapping a thread, but it is too tight a space, and i have tried several bolts but there appears to be no thread so i am really struggling. Anyone any suggestions? I have pics available aswell

    Hello. Does anyone know the stock size for an 84 xs400 maxim main jet size. Ive been trying to dial it in since I bought the bike. It has K&N pod filters. The bike had 2 different main jets when I first pulled it apart.I've had 125,122.5,120 and since I don't have 117.5 ill be putting in 115's tomorrow. Also I can find lots of parts and info on 83 maxims but hardly anything on 84's. Why is that???And before it is suggested I will not be reconnecting the stock air box. Thanks

    the headlight on my 1983 XVZ12T will not come on. We checked the voltage there was 4.5 volts at first, then we started to trace the wiring back and it jumped up to 12 - 13 volts. I have checked the voltage at the switch and there is 13 volts. the bulb is good, but the light still will not work. could it not be getting the correct amperage? We are stumped!!
