Hmm yeah I am convinced it was. I have been riding it a bunch the past few days, and by now, 2 tanks later, its cleared up entirely.
It was weirdly intermittent, I guess it picking up an amount of water into the pump would give me weird engine running for a minute or so.
The seal on my gas cap is a little crusty, but probably just more old than anything. Which parts get replaced typically?
I'll probably seafoam my bike again since its been a long time since, and couldn't hurt after the last couple big engine jobs.
Thanks for the suggestions guys. Shes running great, hit the twisties a few times lately, and its been great fun.

|Kennylxix||Yeah water in the fuel can cause all kinds of running issues.|

Hmm will do. I looked at it yesterday in the garage and it *looked* okay, no tearing and not kinked. It is old though, maybe it would be worth replacing. Water picked up by the fuel pump would cause strange running and low power? Thanks

I'm thinking the gas cap may be allowing water to enter the tank.
Water in the fuel will do what you described.
I'd check the condition of the seal and look inside the tank to see if any water is sitting at the bottom.

The priming sound you hear is the fuel pump running. It runs constantly when the engine is running.
It's possible a little water got into the tank. Water is more dense than fuel so it will go to the bottom. It may have worked it way through the system and fixed itself.
It could have been electrical as well. Without it continuing to happen there's no real telling.

As I suspected.
Let er warm up a real long time in the garage to maybe boil off any remaining water inside the bike, hit the freeway on my way down to the local twisties, and rung the hell out of it. Worked totally normal.
I've found though that my motor stays warm pretty long when its in my stagnant garage though, so to me it was literally cold after like 10 minutes. Typically, after 10 minutes, the whole block is still radiating heat out of the bike. Oh well, it is back to normal now.
That's gotta be electrical right? It didn't feel like ignition problems, it felt like fuel delivery problems. But of course Im using the same tank of gas right now. This gas is a few weeks old, I filled the bike all the way up before taking it apart for a repair, but it ran fine at when it was dry. So it's not the fuel.
Maybe I was tripping, but I swear I could hear the fuel priming sound while the bike was running when it was soaked and I just got home and started troubleshooting. It sounded like it was continually running or something, but I couldn't hear it clearly enough to exactly say, but that was my immediate thought, so you could probably imagine the sound. I secondly thought it might be my fuel cap key hole whistling like some bikes do, but I opened and closed it and it looked fine and had no weird pressures or anything.
Is that possible? Could the priming action get stuck on? It didnt happen just now when I wrung the hell out of it on the twisties. I got it real hot to make sure all the water is gone, and it is.
Thanks for the input, if a cheap replacement of wires or sealing something up would help with this, I'd be all on board.

First thought would be electrical because of the heavy rain. The other thought would be water somehow got into the fuel tank. Let's see how it is after it dries out.
Riding in the rain will keep things cool. Being able to hold onto the clutch cover 10 mins after it's been off doesn't seem unreasonable.
Keep us posted.

Throttle issues in the wet?
Was all giddy to have my 300 fixed, it ran perfect, and today I got stuck in some thick rain, and my throttle was acting up.
The bike sat 2 hours in very heavy wind/rain unfortunately while I was in class. Not like damage concerning amount of rain, but definitely a lot. Then I had to ride it 10 minutes home on the freeway.
Starts up fine, and didn't stall, but the throttle response all across the whole band was dummed down a bit. Not as much pull at all rpms, and when I pulled off the freeway and came to a stop at my exit, it had a lower idle around 1000rpm. It came back up to 1450-1500 (where I set it) when I blipped the throttle. I noticed trouble downshifting because the throttle response was weak, it wouldnt gain enough rpm so it felt.
Got back to my garage, did an oil change I was planning on doing for a while, and while running the bike to get the oil circulated, I noticed if I give it throttle while it is idling, it stutters briefly, then ramps up rpms. Every time it stutters like that, but once its above idle it at least sounds normal.
I am going to let it dry and go out for a nice normal ride probably tomorrow if the weather allows to see if its better. It was running literally perfect before the rain. I've ridden in rain before, but perhaps not this much of it.
Ideas? Things to check? sounds electrical, but I suppose there could be water in places its not supposed to be. Oil had no milk, so no water in there. Also, the motor was surprisingly cold after riding in the rain, even with 10 mins of 70mph operation. Parked and did the oil change like 10 mins later, and I could touch the clutch cover easily, it was lukewarm. Oil was not hot at all, just warm.
