Hello there people of the internet !
You might remember me from such hit as:''starter issues''. Lets call this a part 2 to that problem.
I did not feel like continuing it onto the same topic since this is not related to starter anymore.
So, the problem i have is that the bike runs straight to rev-limiter, if i turn off the choke/half-choke.
The problem is less noticeable if i'm actually trying to ride the bike and thus put more resistance for the engine. Riding the bike i can use throttle aswell. The bike will still want to rev, without touching the throttle at all, this all happens with half choke, it will just die if i'm running on full choke.
I never turned off the choke fully while riding, partly because i was concentrating on staying on the road.
My intake port on the cylinder is: 25mm
Intake manifold is: 27mm
Carburetor is: 22mm
My question is, does the oversize carb/oversize intake manifold cause the engine to suck more air and thus start to rev it.
But then again, it will rev even without touching the throttle.
The throttle slide on the carburetor doesn't go all the way down in the carburetor, but then again the idle screw is fully open and the mark of the idle screw on the throttle slide is as high as it will get, so this suggests me that the throttle slide was never meant to go lower in the carburetor.
As you might have guessed, the intake manifold doesnt sit perfectly on the carb/cylinder, could it cause the engine to suck more air and start to rev ?
