My F2 when I clutch a wheelie up, I'll drop the clutch, then about half a second later the chain snaps and pulls the wheelie up, and the chain continues to slap every half second until I set it down.

The chain is tight so it's not the chain what the hell is wrong with it.

 

chain has a tight spot or there are teeth missing off of the sprocket.

 

Oh yeah I forgot to check my sprocket I'll go do that.

 

sprocket has all the teeth. It was happening yesterday in the day time, then stopped at night, which leads me to believe that it's only happening when the bike is hot. There's 10w40 motorcycle oil in my bike maybe it's getting too hot and the clutch is slipping?

 

how about the front sprocket? doesn't sound like a clutch problem.....

 

Front sprocket is good, both look brand new. The chain is rusty, I dunno what the problem is I'll clean it with WD40 and lube it and see if that helps.

It's doing it at high RPMS now too not just in a wheelie.

 

sounds like a clutch problem now.

dopes it do it in all the gears or just first?

 

All gears at high rpm, I did notice the chain is kinked in some areas but I doubt that's the problem.

 

I'm gonna go get video of this so you can hear the sound.

 

Ok, the first video you can't really hear it slapping, but it does it 3 times at the top of first gear, and twice at the top of 2nd. The bike does this at any speed if I clutch a wheelie.

Second video is of the chain as I accelerate in 1st gear.

deff titghen that chain.

my guess is the clutch

 

if you have kinks and rust then its a bad chain PERIOD. clean your chain with some kerosene then lube it or replace it

 

From the looks of it your chain is pretty loose...
