Problems with my bike

So I recently purchased an 03 600rr. It came with several mods on it. The list of mods include a power commander 3, speedo corrector, 2 brothers slip on, and a steering stabilizer. Well, last night, I filled up my tank all the way, there are 6 notches on the indicator. I took it to downtown area today from my house which is about 1960 area going the limit, and again down to 610 and Westhimer area later that day as well going the limit. When I got home, the notches went from full, down to two. I noticed that I had pretty low mpg for a bike so I just disconnected the pc3 ground wire so it wouldnt turn on anymore but is still connected everywhere else on the bike thinking that would help, this was before my ride to 610 and westhimer. After doing that, my bikes oil light came on twice while I was riding and killed the engine. That never happened before. Any ideas? Is it the mods thats killing my mpg? Should I reconnect the ground wire to the pc3? Any and all advice will help. Thanks in advance!

-Dan

The RPM runs around 6 and just under 7 at around 7mph and I filled her up with Shell V-Power if that makes a difference at all. Thanks again!

Something very similar just bit me. The red light you are seeing may not be the low oil pressure light. Look very carefully at the annuciator (warning) panel when you 1st turn the key on. I think you'll see a small indicator symbol that shows low oil pressure. If so watch that indicator when you start the bike - if it (the small oil pressure indicator // not the red light) goes out and the red light stays on - it most likely doesn't have low oil pressure. If you have your owners manual look at the page that explains all the warning function. Also - when you start it watch the oil sight gage (if it has one) and when you start it if the oil in the sight glass goes down - that is a good sign.

prob throwing a code because its not getting a signal from the pc3 also try changing the map thats on the pc3 or go back to stock gearing for better mpg because if its go a speedohealer the guy had changed the gears on the bike prob to -1 front and maybe +2 in the rear so that will cut into your mileage right there

Also check your air filter and oil to make sure everythings In order and clean

forgot to mention he did replace the front and rear sprockets to -1 in front but it is stock at the moment and +2 in the rear. Air filter and oil should be fine, recently serviced by Motorcycles Unlimited. Thanks again! I'll try to change the map on the pc3 later today. Not entirely sure on how to do it but I'll manage. I really just want to take the pc3 and the speedo corrector off.

well both those trips would be around 80 miles, depending on where you live on 1960. Was there any traffic??? Because that can eat up some gas quick. What is you average MPG? I would definately plug everything back in. Electrical systems dont like to have gaps, thats prolly where your code came from. If your bike is regeared, and has a PC-3. Then i can see how you could burn that much gas IF there some traffic.

I live right by 45. Not exactly 1960, Richey Road, it is first exit south of 1960. I just plugged the pc3 back in and I reset it back to stock settings. Now all I need to do is change back to the stock rear sprockets and everything should be better. I wouldn't say it was an 80 mile round trip each way, maybe 60 or so, and there was no traffic.

Well here is a little update on my bike problem. The only thing different from before is that I replugged the pc3 ground wire back to the battery, and that stoped the killing the bike randomly. My mpg still sucks though. I filled her up again with shell v-power today with 2 notches left on the indicator, took her back home (it was maybe a 7 mile drive round trip) and I took her out again to the starbucks off west road (maybe a 20 mile round trip) and it dropped a notch. I know I dont know alot about bikes, but I do know they are supposed to have awesome milage and my camry takes less gas than it. Probably will take it to Motorcycles Unlimited later this week...

the power commander is prolly killing your mileage. gearing doesn't help. put it back to stock and watch your mileage go way up.

If i remeber correctly my RR got poor gas mileage also.

Just cause your riding at posted speeds doesnt mean your going to get great gas mileage if your not using the appropriate gear.....just a thought
