Hi, I'm the new owner of a used WR426. It's my first offroad bike. It looks like I get used with this bike and I observed the detail described below. When I ride the bike in the first gear and I roll off (release) the throttle the engine doesn't idle but stays little higher even I roll off the throttle by hand. More than that, if I want to idle the engine I have to use the rear break. Another scenario: I pull the clutch, roll off the throttle and the engine doesn't idle but it's a little bit higher. At this moment, if I release the clutch lever then the engine idle when the first gear is connected. Very important here, when I pull the clutch again, the engine idle. First assumption is about throttle cable but I do roll off the throttle by hand, not just release it. In neutral I roll on the throttle 1/4 and release it immediately. Very rarely the engine idle after this action. The second assumption is about the carburetor. Maybe a cleaning is required but the engine (+the carburetor) should be consistent and doesn't idle in above scenarios. The third assumption is about TPS. I read on this forum about TPS mod and I disconnected it today for a while. It looked like the idle is better. I'll continue to experiment with TPS on/off. I cannot figure out how TPS can influence idle. Please, can someone give me some suggestions or logical explanations? Regards.
