So I'm having a problem with my throttle. When i'm at speed either maintaining speed or acceleration my throttle jitters, it's completely inconsistent.

I've recently changed the plugs, tightened the chain and cleaned out the carbs. I've inspected the harness, checked the grounds and all the connections, but can't figure out why this is happening.

Any suggestions/help would be greatly appreciated.

 

Fuel flow restricted? Is your whole bike shuddering? Or just the throttle body/control.

Hope it helps.

 

Didn't forget any connectors? Is your fuel pump working correctly? Might be starving the carbs somehow.. Then again, might be an electrical issue.

 

Hi all,

Thank you for the responses, I finally figured it out. The problem was electrical due to the fact that I changed the dash for an aftermarket unit. In this process I didn't realize that in the wiring diagram the 20km/h (pink/yellow) wire is a sensor related to the ram air solenoid. Since this was closed when I was at speed the engine was basically being starved and hence the inconsistent throttle response. Thus if you are not using a dash, or are using an aftermarket dash, you need to ground that wire to open up the ram air. The bike is running perfectly now!

thank you for your suggestions and help.

Cheers.

 

i have my speedo wire unplugged because if its hooked up my bike will stall, should i grond that wire too?
