Hi,
as we all know almost all motorcycles of today still need periodical valve adjustments. So they aren't hydraulic lifters.
But there comes my lack of experience: Are modern motorcycles still flat tappet cam shaft driven or do they rely on roller cams?
For example: The Piaggio 125cc Quasar engine, used in the GTS 125ie - I have googled pictures of their cylinder head - but I can't tell the system they've used, I can see two actuator arms, springs and hidden underneath is the camshaft. What kind of system is that?
Or a Suzuki Boulevard C50, first picture on the right on this site: http://www.bikerbits.com.au/adventures/boulevard_adjust_valves.shtml
what kind of system is that?
More pictures of the C50 cylinder head here, should be the first offer: http://www.bikerbits.com.au/adventures/boulevard_adjust_valves.shtml
-> btw. I'm not sure If I'm allowed to directly link this?
Thanks for the education,
Alex
