Dio Boggs at Mid Throttle only

[el_walto]

My scooter is all of a sudden is bogging, slowing down mid throttle.

If i can get it to full throttle without stalling it works fine. Idle works fine; full throttle works fine Any Suggestions?

Just cleaned carb and replaced head/cylinder 500km ago. Could this somehow be the auto choke?

Having the same problem and haven't found a solution yet. Seems to run fine right when it starts up and then once warm it starts bogging. Makes it seem like the bystarter to me too.

this happened to me. What I found what my problem was a small air leak on my intake side. Check your vacuum lines, intake anything to do with a leak. Mine would idle good and full throttle was good just towards the middle of the throttle area trying to get full throttle it would bog. And sure enough the leak was small so it wouldn't really affect the idle as much and when I full throttled it enough gas and air was going in that it didn't show it had a leak. So check it might be a leak.
