Hey guys..I'm new on the forum ..been reading every time i had a problem with my bike, but now i didn't find anyone bringing this up..I have the bike since 2013, it's a 2009 model with 10k miles on the clock(now it's got 13500 miles).About a week ago i've noticed for the first time after a 200 mile ride when i've got of the bike with the engine hot, running and on the centerstand, that i can see the oil level in the engine sight glass right about where the minimum indicator is..That leed me into thinking that the oil pump does not pump all the oil into the engine, and just a small amount while engine is hot, running at idle and on the centerstand..because i live in fucking romania i dont have a qualified yamaha mechanic or workshop to be exact, and just went to my local motorcycle mechanic that told me that these r1 2004-2008 engines are renowned to have week oil pumps and as the oil gets hotter it gets really thin and the oil pump does not pump it fast enough..the oil i've always used is 10w40 motul 300v that he said it's very thin for this engine that gets very hot, and this oil is more for the race track..his recommendation was in the first instance to change the oil to a 10w60(wich he said he used in all of his bikes) in the ideea that it will be easier to evacuate by the pump when the engine gets hot and the oil won't get as thin as this one..I have no ideea if what he says makes sense cause i am thinking that the oil pump will have to work harder with this heavier oil..
PLEASE!! I am asking u guys for some help(i don't know anybody here with this kind of motorcycle, and guessing there are very few in romania)..put you're bikes on the centerstand and warm them up to 210-220 when the fans kick in, and watch the oil thrue the engine sight glass..tell me if the oil level rises to the minimum mark when it gets at 210-220(or after 10 min of running when it's very hot)..I wanna know if this is a thing that this engine does or is it a problem with mine..thank you
