Twitches after the beginning of the movement! Help me, i'm so tired
Hello ppl's, sorry for another thread, but I really need help.
I have no one to consult about my problem.
Noticed this about a month ago
I have a problem, when the engine is warm, there are jerks at the moment start move. Also, if I go to idle speed and fast open throttle motorcycle starts to twitch 5-6 seconds and then normally accelerates.
I thought it was FPR again, but there are no signs, all the pipes are heated identically, bike rides smoothly on low rpm (2-3k rpm), in a vacuum hose is no smell of fuel.
What was done:
I cleaned the injector, changed spark plugs, checked the ground on the frame, checked the fuel pump pressure, there is normal, did valve sync, measure the resistance spark plug wires (1 cyl 4.88, 2 cyl. 4.69, 3 cyl 4.96 4 cyl 5.16).
What else can I check? Does this sound like a clogged fuel filter?
Sorry for my low english.
