I have a derbi senda 50cc and I was wondering if my main jet size is too small because I ride on road and a little bit offroad here and there.
My main jet size is 70, my cylinder and piston seem perfectly fine and there's no sign of too lean mixture.
Should I test it with a new spark plug and run it for a few minutes?
Ok so I have this 2008 derbi senda and I noticed this weird branch section from the main pipe.
My questions are: What is that? Does it help with anything? Should I remove it and weld something to cover the hole?
And yes the exhaust is off because I had to work a little bit on it.
Ok so the other day I tried to mess with my throttle cable because the carb was not opening all the way.
Long story short when I let go of the throttle this thing from my cable snapped off.
It doesn't have any screw or something to hold the wire, I believe it was welded on or sum.
Can I just drill a tiny hole trough or just buy a screw-hold one?
Are the screw ones reliable? Please tell me quick cuz I just done fixing it a week ago amd just wanted to ride a bit...
Hi, how do I know if my bike has the right main jet size?
Mine is a 2 stroke. Are the methods the same for all 2 and 4 strokes?
I am afraid because I might seize my emgine if I don't act immediately
