2007 Cr125 Please Help!

[peterttr230]

Hey guys I have a 07 cr125. I went out the other day on my bike and it would not stop fouling plugs and I couldn't even ride without it fouling. I dont think it is a jetting problem because it has been running perfect for quite a while. It fouled plugs once in a while when I was riding slow as the bike is not set to idle and is meant for racing. I was playing around in the mud the ride before, could it be dirt in the carbs or a blocked carb line? choke stuck on? float valve to high, dirty? Fuel mixture screwed? ( I will mix a new tank and test before I tear anything apart) Please help me and give your opinion I would like to ride for the rest of the season and will be cleaning everything + new rings and piston during the winter. Please help , thanks for reading!

Start with a fresh batch of premix..... then go from there.

Have you cleaned the air filter? Vintage Bob

I havn't cleaned the filter since the last ride no, but I do clean it every couple rides. Would that make the plugs foul though? I will check it out tonight thanks!
