The bike went for carb. wash already. Immediately after leaving
the shop problem comes back. I notice something - My bike is a
V-Twin. When started, the front part (is it call piston?) give out
more heat the the rear one (very significant difference). I suspect
that the rear one is "eating snake", so might have affected the
performance. In another words, the engine not balanced. As to what
caused this, still figuring out. Might be spark plug, carb. choke,
piping problem, or even piston not tune properly... who knows? I
only beginner leh.
