Hey guys, need some help. Really scratching my head on this one. 03 crf450r project. Brand new 13:1 wiseco piston in it. Bike will only start by push starting it. And when it does start, seems like it's super low on power. Feels like I'm riding an underpowered Harley. No hit at all. Piston hasn't even been broken in yet, that said, haven't revved this thing up either, it just feels super weak. What would cause these symptoms? Could it be the carb? The bike is popping a lot but I didn't think the carb really could change the power this much and even have the bike run? Before you all ask, the timing is right, I've triple checked that and the valve gaps are in spec. Only thing I can think of is carb or cdi but I'm confused on this one for sure. What do you guys think?
