There can be multiple reasons for this. Low fuel presure is one cause of this.

If you had dropped the bike the impact can loosen the fuel lines inside the fuel tank. Issues with the fuel pump can cause a low fuel presure. In my case the fuel line was loose but still pushing some fuel into the lines. There is no issue a low rpm cause there just enough fuel to run it at 2000 rpm or lower but not enough pressure to run well at high RPM.

2004 triumph daytona 955i. Engine makes a single knock that can be heard when transitioning from idle to throttle. Does not knock continuously nor throughout the rev range only once when opening throttle...


Apparently it's the SAI value that's causing this symptom on my 955i - It closes at 2000 rpm (or so) going up and opens again when the engine speed drops below 2000 rpm. I'm told that some bikes have noisier valves than others, but they are solenoid driven so a click or knock is to be expected.

My poulan wild thing 2375 bogs out when throttle


Make sure that the air cleaner and muffler are not plugged. Check the carburetor screws and nuts for tightness. After turning both needles CW to stops (lightly), back them out CCW 1-1/2 turns each. Start the engine and allow to warm up. Open the throttle and adjust the H needle CW somewhat until the engine speeds up, but is 4-stroking. Correct adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Release the throttle and adjust L CW till the engine runs fairly smoothly, but allows the engine to 'follow the throttle'. Set the idle speed screw so that the chain doesn't turn, but the engine keeps running. Hope this helps!

Could be throttle bodys need synching,first adjust your TPS
(throttle position sensor)as per factory instructions.It will show you how to in a haynes manual.If the problem still persists,it will need throttle bodys synching.Its just like carb balancing on older bikes.they do run out as milage increases,its no major problem.
