Simply take off tupperware (seat off, METIN box out) and have a look where it belongs to.
No. That looks like the end of the 'puke tube' - a tube which drains the airbox.
hey guys, thanks for the reply. i havent checked exhaust gasket as i dont think there should be difference between no-load and load, i thought if it was gasket it could be heard when on center stand...for the unusual sound at 53 and 59sec, its probably toolbox as i carry one under seat so i probably rode over small bump and it rattled little bit :-) i was thinking maybe it has something to do with PAIR system? from what i've read it should dump some fresh air into exhaust to burn excess fuel that leaves cylinder unburnt-this might explain why i hear something similar to spark knock? and it would probably resonate thru head back into valve cover part resulting in echo ? it is weird it is always there, only after half throttle and only under load... i am running out of ideas however i will visit kymco authorized repairguy in my hometown to let him listen to this, he has years of experience with kymcos so he might be able to help without actually taking apart half of the engine hehe, will post what i find
and to the valve clearance, i used 0.1 feeler gauge however, its very loose on both valves(still cant stick in 0.15) so we are somewhere between 0.1-0.13+- and as there are no start/performance troubles and tapping i guess its all fine =)
