Limp Mode

[jackel46]

So I have a 2000 Ultra 150 which seems to be stuck in limp mode ( it won't go above 3500 rpm's or over 10 mph). So far I have replaced the air temp sensor, water temp sensor, and the fuel level sender switch and it still is in limp mode. If anyone has any ideas of what else could be causing it, please help. Thanks....

I just had the top end redone over the winter, and put brand new carbs on it. Doesn't really seem to be an engine issue, all plugs look good.
