YZF750 shutdown

[IceCream Bandit]

When I ride my bike at high rpms for extended periods of time(reaching top speed on highway) my bike cuts out, I switch it to reserve and it's fine, if I slow down and drop the revs I can take it off reserve and it runs fine; it does it even when it is nowheres near empty. Anyone know what the problem could be?? <p></p><i></i>

Good job Columbo I pretty much figured that out already, not to sound like a smartass but do want a gold star? I"m personally thinking there may be a problem with the fuel pump because I can switch it on reserve and it runs fine. I am unclear of how the fuel delivery system works, I know there is a vacuum hose to the pump assembly but is that for the reserve and the electric is for the regular operation; or is the vacuum line for the regular operation and is the electric is for the reserve?? <p></p><i></i>

Ohh, Ohh, are you giving away GoldStars? Think my grandpop used to have one, must be worth a mint in classic circles.<br><br>The pump will be required at any stage I’d imagine & the vacuum hose just stops the tap leaking when you pull the hose off. You should hear the pump working anytime the carbs have drained of gas. Do you?<br><br> It is possible I guess that the filter on main is blocked, usually it would be reserve that should more likely get blocked.<br><br>May be able to see something with a flashlight & an empty tank. Failing that the assembly comes out easy enough, but sealing it after is important.<br><br>Can’t find that damn torch, all I got is this cee-ga-ret lighter & . . . <!--EZCODE EMOTICON START :x --><img src=http://www.ezboard.com/images/emoticons/sick.gif ALT=":x"><!--EZCODE EMOTICON END--> <p></p><i></i>
