Hi there,

I'm rebuilding a 99 F4 to a stuntbike.

Now i've heard about a problem whith stoppies and wheelies whith this bike because of the carbs??

Does anyone know more about this problem and how to solve it?

Thanks a lot!

Is still think its a weird solution to just close the fuel supply.

Hope to hear different solutions

Are there problems whith high wheely's to?

go try it out steve! just roll some stoppies as soon as you get the dirtbike bar, see what it does.. maybe its not too bad, maybe it is..ask scott chychul on this forum, he kills an f4!

The shutoff valve works great for stoppies. The setup costs about $6 and is easy to hook up. I have the valve attached to the subframe on the left side, right behind my knee. Now when i do stoppies i just turn off the gas before i speed up. You can run it for a few minutes with the gas turned off before it starts to loose power. After i do a few stoppies, i turn the gas back on for a little while. I can practice stoppies for over an hour strait now and the bike still runs great. If i don't turn the gas off the bike will die on the first or second stoppie and will run like **** for 20min.

Oh and the carbs are fine for wheelies. Even on the bar it doesn't sputter before the oil light comes on.

isnt it possible to make a switch for the fuel pump??
Or is shutting the fuel pump off not enough ?????????????????

Oke. I recieved an e-mail whitch sayd that just turning the fuel pump off isn't enough.

Until now the only solution is to close your fuel line whith a valve.

I'm going to inform if it's possible to do this whith a swith and a electric(magnetic) valve. Hope it possible and not to expensive.
