Ok replaces the gas and fuel filter still same problem.... Tore down and checked the throttle position sensor and saw no big spikes.......Just general drop when you hit the throttle....

So now Im confuzzled..... what to do??

 

I would really like to help you out on this one. Did you do a fuel pressure check in the line between the fuel pressure regulator and the injectors. You might have enough pressure for starting but when the flow increases as you accelerate it might be dropping off due to a resrtiction in the system like a swelled o ring in the quick connects or a twisted or pinched fuel line. Did you dowload the manuals? Do you have the D&m kit and software. There ar many things that can cause problems but if you dont have the tools or info to fix them it will be very frustrating. You said something about a fuel line update which makes me wonder if they damaged the line . Are you the one who drowned his dale in a river. I need as much history and info as possible to help with the diagnostics. Its the best I can do without the machine here .How far are you from wausau WI PM me if you like.

 

Im about 5hrs from Wausau...... I didnt drown my dale.. it just went out a couple weeks ago while riding down the straight.. I have the parts and bike manual..... Fuel line has never given me trouble...R&s did the re-routing..... Like I said whne I hit the throttle the meter dropped slowly...

 

My bad ,there was another post about the tps that had to do with water.

 

I was just reading the service bulliten on the fuel line O ring problem and the classic symtom is engine stalling upon throttle opening. You have to install a pressure guage in between the fuel pressure regulator and the fuel injectors and measure the pressure with the engine running. If it changes from specs then the fuel line connector orings are swelled, the connectors might be loose or the line is pinched.

 

Ill check it out and see......

 

Hey, my Cannibal was doing the same thing, turns out the pos. battery termial cable was loose because the nut was missing, I just found a new nut, and it's running better than ever., Hope this helps. Also maybe check all of your fuel lines, check for kinks.

 

My bike used to drown out when you cracked the throttle open real quick. All I did was bump up the idle. It fixed my problem and made my throttle response better. I don't know if this will help you because I don't have the GP fuel system like your bike has. Well, I hope I could be a help to you.

 

Alright...............Fixed.

Thanks to Swamper38's it was the positive terminal on the battery... Tugged it a lil while running and Boo YA...

I just wanna thank everyone for their help... Im glad it was only this.......[img]i/expressions/face-icon-small-happy.gif[/img]
