Working on a 99 F4 Track bike and thought it was ready to go for my next track day.


Put in some new gas, tank is 3/4 full and started it up. Runs well, idles perfect ect.


Pulled the bike off of the kick stand and leaned it to the right a bit and the bike died. It started right back up. Leaned it to the left and it kept running, Leaned it to the right again and it died again, this happens every time or when I move the bike to the left and right and slosh the gas.


Do the F4's have a tip over switch like my 600RR had?


What in the fuel system could be causing this?


Any help is appreciated.

 

Dont know, go to a online OEM supplier and look at the schematics. Should be able to tell then.

 

Checked the repair manual and no mention of it in the wiring diagrams

 

I would look at the wiring. Sounds like you have a slight brake in a supply wire. Take the seat off and try moving all the wires to see if you can replicate the fault.

 

They don't have a tip switch unless this has been modified. As far as I can see, turn the hndle bars fully left then fully right while bike is running, does this cut engine?
