I'm rebuilding my gf's cb200 engine. I've read here and on other blogs that oil flow to the camshaft is a bit tricky.
My plan is to make an extra oil line from where the oil fillter sits to the both "cam-bearings".
On the non-ingnition side that won't be a problem, but on the ignition side it will be, due to obviously, the ignition parts.
When oil in the engine is sucked up by the pump and spit out at the other end, it goes directly (thru this 1mm hole between the crankcase and cilinder) to the head and cam. BUT, the oil gets to the other end of the engine as well, lubing the big-end bearing on the flywheel side.
I also noticed that the oil filter does not filter oil going to the head. Oil to the head goes from the pump directly to the head and there is a seperate oil path for the crankcase and such. Strange, cause the cam-bearings need clean oil so badly.
Long story short, my question is:
When i make an extra oil hose from the right cover oil line (remove the little pushed-in rod and fix a banjo) directly to the cam-covers (eliminating oil-problems due to gunk in the 1mm hole), will there be enough pressure left to oil the rest of the engine. The only reason i can think of why that hole is sooo redicilously tiny is to preserve oil pressure to get oil everywhere. When i make an oil line, the oil pressure drops. Will this cause trouble?
I want to do this mod because i think it's better than original and i'm competent to do it. And it will look sexy
Planning to do the mod a little like this, but than to the head and no retour line. Oil will go back via camshain.
cb200 engine is similar to the one (175cc) in the pic. The outside oil-line won't be needed.
the picture is being a pita, dunno why it wont embed. sorry.
