Bike not running right, loss of power, gas? PLEASE READ!!!!!

First let me start by telling ya I have a 2003 R1.... and I woudl like to thank everyone who reads this cuz i know its kinda long...... now heres the problem...

Some buddies and I went out for a nice long ride yesterday. I stopped at BP and topped off my tank using 93 which was already about half full. About 25 miles down from filling up on the E-way I was keeping it steady around 90 mph... not stepping down on it or anything... just cruzing at that speed.... I was in 6th gear and the bike acted as if i just totally let off the gas for like 2 - 3 seconds... then it would come back ( my hand never moved off the throttle) ... i was like wtf was that?

Then it did it again, ...... and again. I THINK the bike might of been running / sounding a lil rough also. I thought it might just be something in 6th gear so I put it in 5th. Went a lil while ok, then it started doing it. I thought it might of just been high speeds or high gears, but when getting off the exit I had it in first and it was doing it again... After getting back on the Interstate it was doing it again and then the bike just quit!!! I got it started back and the rest of the 35 - 40 miles back home the bike acted fine. No problems what so ever???

After getting closer to home I started really getting on the bike and what not trying to make the problem come back if I could but it wouldn't. Two things that MIGHT have smoething to do with it... I put 1/2 take of gas in right before the trip at BP using 93. (I already had a 1/2 tank, so i just topped it off) and getting onto the Interstate I did a big wheelie and after coming down I hit the rev limiter pretty hard and it make a loud back fire noise.... this could MAYBE or MAYBE NOT have ANYTHING to do with my problem. ....

Well the bike has been parked ever since yesterday but today after work I wanted to take it back out and see what was going on..... got it out and the first like 10 mile the bike seemed to be acting fine... then it started doing that thing where it was like it wasn't getting any gas, or i was letting off the gas for a few seconds (but i wasn't) .... I could also kinda feel like a vibration .... and it didn't sound right, and didn't feel right.... Im sorry I can't really explain it that well...... But I got it home and parked it. Please.......... any ideas?????

Go with the simple things first. Plugs and trash in the tank. Pull the plugs, check them fouling. Drain all gas in the tank, and flush out with new gas / fuel system cleaner.

Has the bike been sitting for a while? Is it new to you?

Kinda rules out trash in the tank, but maybe not. Good luck and keep us posted.

Check your battery connection and battery voltage. Loose wires often cause such intermitten problems. Further, your battery voltage after the bike has been sitting like over night should be at 12.8 volts. Further, if you then start the bike and rev it..the voltage should rise.

You would be surprised how F'ed up a bike can get without the proper voltage and power to its ECU.

Also, if you want to go crazy... check the voltage, then remove the battery and shake it... then check it again. You might have a plate going bad in the battery and it might be arching inside its case. Or it could be low on acid.

I would say before you go dumping out the expensive gas and changing your plugs check your battery like gasman said! That sounds more like it to me. But it never hurts to change your plugs!

What kind of plugs are in it now? I dont think you need the most expensive plugs on the market. But it's your rig, not mine. I'd find the root of the problem before I put top notch stuff in it. A normal set of NGK's will cost you $40 bucks for a set. I'd start there.

UPDATE!

.... First I want to thank everyone that is trying to help me with this nightmare problem.....

Ok, tonight I spent the evening taking the gas tank off the bike. I spent like an hour (no joke) draining the tank into a white bucket by flipping the tank upside down and getting the most out but then having to shake it for like 45 min to get the rest out (pain in the ass!) ..... but finally it was empty. I looked in the bottom of the white bucket the gas was in and didn't see any water what so ever and the gas was like a pee yellow. I didn't know gas was that yellow but then again I'm use to seeing like 87 for like lawn mower and what not. I thought the 93 might of just been a different color. I drove up to the Shell station and got 2.75 gallons of their 93 (which was the same color yellow) and put that in my bike. I turned the key on and off a few times to let the fuel pump do its thing (didn't see as loud but i could just be imagining things by now... ) And then I stated the bike which started right away... I let it run for a lil while and things seemed ok, but I did smell this funky weird smell that I've never smelt before coming from like the bottom of the bike... like near the kickstand? I don't even know how to describe the smell??? But I didn't want to go far in case the bike went out on me so I just took it around the neighborhood...... everything seemed to be just fine, no problem. I wanted to get the bike hot so when I got it back home I left it running.... came inside changed clothes and took the bike back out..... I bet I didn't make it not even 2 - 3 miles and it did that same thing to where it felt like the bike just lost power or as if i took my hand off the gas... I thought o ****, i better turn around and get it back home.... I turned it around and it was running like ****... doing that same thing, and just sounding and running like crap. Kinda bucking at times and what not. I got it back in my neighborhood and on my street it just died on me.... I tried to restart.. it did for a second then died... started again.... died.... started again .... died...... got it in my drive way.... started.... died..... THEN .... it wouldn't even turn the bike over................ i was hitting the start button and nothing was happening at all. ........... NOTHING .......... I turned the key off sat for about 1 - 2 minutes.... started it up right away and the bike sat in my driveway and ran for a good 10 min just fine before I turned the bike off myself and put it in the garage.............??????????????????????????????? ?????????? ................ No idea but I can tell ya it wasn't bad gas

I'm standing behind my inital re-action. Sounds like its electrical. I'm willing to bet its a crank sensor going FUBAR when the bike gets hot. Or something simple like I said... a bad connection or short.

Either way... electrical!

I hope it something simple and I do agree that it does seem like once the bike is hot it does it more....................... but then it makes me think... When this first happened and I had to make that 40 mile ride back home from where I was.. after it was messing up on me on the eway and then just died and I started it right back up..... the whole ride home it was fine... and trust me I know the bike had to be just as hot the whole way home?

........

Also..... I got it to the shop today. The service manager took the bike out for a good 20 - 30 min.... came back and said he couldn't get it to do the problem what so ever! I told him to keep it and take it out for a longer ride later on today and call me and let me know of anything that happened.

Well I went to pick up the bike today. The service manager road the bike 6 times over the course of 2 days....... never once messed up on him. I found it hard to believe but when I went to pick it up I took it out for a good hour and it didn't mess up on me one time..........? Its now sitting back in my garage... have no idea what could of caused this. But it doesn't seem to be doing it anymore?

It's the age old addege...you can't replicate your problem when you have it at the mechanic's. Keep riding and see if it does it again. Maybe it was bad gas and the jumping was the remaining gas in the lines.
