Hi people, My bike (2009 Husqvarna wr250) has been running like a dog lately. It won't hit band when its cold and it's just generally not running like it should. I took my reeds out and there is a slight light gap between some of them, roughly .07mm gap. It's not a huge gap but I'm not sure if there's meant to be a tolerance of some sort as it does not state such a thing in the workshop manual. From what I know reeds should be dead flat with no light gap at all. However, I will be replacing them just in case. Some people who I have spoken to have advised making sure thet the carburettor jetting is set to standard. I have the Husqvarna workshop manual and have found the "standard jetting". Problem is it's just a whole heap of numbers and codes so I have literally no idea what it means. The only thing I understand on it is that the pilot jet should be set on the second slot which it already is. I was hoping someone on here could make sense of it. I have attached images of the husqvarna manual jetting information. Thanks for the help in advance -Ryan
After doing the basic mods to the ttr 230 (changing the main jet to a 130 and pilot jet to a 38, removing silencer in exhaust and the air box mod) the bike now does not want to start. I bottomed out the fuel mixture screw and took it back 1.5 full turns and it will not start. The bike was working fine before the mods. What have I done wrong? EDIT: I’ve adjusted now so it’s 1 turn rather than 1.5 and it starts now, but when I rev it a bit, it cuts out. I then immediately stop revving it and it returns to idle and then idles normally. Any help is greatly appreciated.
