What did you do to your bike today?

[Mototrav22]

Anyone have a drill press w/vise? Need to drill hole in handle bar. Installing new clips..

Took off my tank today and checked all the vent hoses... none of them were clogged... what else would cause vapor lock?

[Dougk35]

Does the "vapor locking" happen when the engine is cold and or warming up? If so probably not a vapor lock condition. Vapor locking happens when a fuel line gets hot and usually happens after stoping the engine, because fuel is not moving in the lines. Example: Go to the store on hot day. Stop engine. After 5 minutes come out of the store. Engine will not start.

That happened once in utah, once I opened the tank cap I was able to start the bike almost immediately.

Other times it has happened on HOT days in the middle of traffic. Bike will just stop. Open gas tank, too much pressure has built up.. Happened at the poker run to twin peaks a long time ago.. not sure if anyone remembers.. =]

Then it happened when we went to valley of fire. bike was just dying in the middle of going 80+ engine would just stop. bike didnt start working right till we went to the gas station, poped the tank cap, was able to get almost home before pressure built up again..

Your gas cap should have a vent in it.
If its not working right, pressure will build.
This can cause issues with starting the motor.
My Kawis have this issue sometimes when left in the sun (pressure builds faster than the vent valve can evacuate).
I just open the gas cap to vent and then start it up.

What do you do when it happens mid ride? =D

I had this same problem beginning of the summer, turned out to be the fuel pump filter & screen. Pull the fuel pump and check, clean and or replace.

I've never had it happen mid-ride or with engine running.
But, that might point at another issue (not the pressure buildup in the tank).

Maybe I have multiple problems.... lol

But it only happens on hot days. either issue...

Fuel filter on gsxr is notoriously ridiculous to clean.. it runs fine idling,etc, even at high rpms it delivers fuel fine...

Like Jr said, it could be something related to the fuel pump.
Ive seen fuel pumps work intermittently, and if they overheat they can do it more often (if faulty).
Maybe not the filter, but perhaps the pump itself.
Is it the original one ?
