1999 YZ 400F flogging?

[danny86]

I have a 99 YZ-400F.

The bike has ran perfectly fine in the past. Recently, I started to shift without pulling in the clutch ( trying new things)

Now, all of a sudden, at very low RPMs, If I pin the throttle, the bike just bogs until a few seconds then starts moving again.

Again this only happens when Im going slow and I being to open the throttle all the way

Is this a jetting problem ?

Thanks

Flogging? You're bike knows a dominatrix? Its early, what ever? If you are saying you let the clutch out, and it does not engage right away, could be the cable or something wrong with the clutch. Or, the engine is loading up and smoking bad?
