Have an idea after eading all this in mult posts,it seeds the fuel doesn't overflow in most cases untill the ign is turned on activating f-pump which motor at normal op temps & not always when just real hot or overheated either ,but most say it happens more in hotter weather.

And most also said when this happens they eventually get motor fired up after being a littl loaded up and when the motor fires the flooding over stops as maybe fuel pressure even out or some coller fuel enters the carb ,who knows.

What i plan to do is since fuel seems to overflow like when stopping for fuel then trying to restart 5 mins later after carb/fuel line heat soak & the fuel pump is activated when ign is turned on and fuel pukes is put a small toggle sw (mounted for easy access) tied into hot wire to f-pump.

Then when in that sitution with hot start simply turn the toggle sw off ,then post filling biuke up get the bike fired up 1st then flip on the fuel pump after motor is running for 15-20 seconds relieving some fuel pressure or getting cooler fuel into the carb.

I also plan to insulate the fuel lines from f-pump to carb that run inbetween the cyls to keep temp dowm some there too.

Then for safety sake i am going to try to reroute a longer fuel overflow hole from carb out to drain under the bike and not all o=ver the side of the motor & possibly onto hot ex pipes too ,thats an accident waiting to happen there for sure.

But every time i read about carb puking its always post hot shutdown uppon refire a few mins later but only happens when fuel pump is activated when ign is turned on and that's why i fugure switching off f-pump for hot refire like when fueling up and letting motor run a few seconds then flipping on the elec f-pump should remidy this issue since thay also stated after motor fires up the overflowing fuel always stops or at least in most cases.

I never had this happen to my 06 R* yet likely because i just got it and its not been over 60 deg here in NE . But i am going to install the switch on fuel pump,insualet the fuel lnes inbetween the cyls,and get fuel overflow hose extended to drain under bike and not onto hot motor and poss ex that could end in disaster fire like i red someplace thats already happened to ther R* owners.

Its a crime that Yamaha can get away with this even in small #'s becasue it such a safety issue.

But anyway i figure if the ign sw idea works its simple to install and no big deal to flip off when shutting down hot and then simply flipping it back on post refire hot .

I have also read that shtting off fuel few blocks prior to hot shutdown has helped to reduce carb overflow on hot restart but not in all cases i read,some report that it didnt alway work for them.

But there is 1 thing that is conistsnat here which is the fact that everyone repots the fuel only over flows on hot refire when ign switch is turned on and f-pump is activated and over flow stops in most cases when motor is fired up and it runs ok after that so my switch on f-pump idea may be an easy fix for this issue in most cases,you never know.

If i find this works i will then look for some kind of relay and or device that can be tied into hot wire to f-pump that delay 12volt power to fuel pump for approx 20- 30 seconds post ign sw being turned on giving plenty of time to get otor refired and running before f-pump activates/turns on so you wont have to deal with turning f-pump on & off anymore.

Only thng is if bike sat for long enough time and fuel evap'd out of carb you would have to wait 20-30 seconds to f-pump to activate and pump fuel into the carb to fire bike up which is no big deal either.
