i know a LOT of talk about the shitty cam chain tensioners...and most know i do a lot of engines so i thought i'd show a pic of one that failed on a 2009 R1..
here is one a kid brought into us that was bone stock, 1,200 miles on it...riding it on the freeway...downshifting off ramp (he races too and is not an idiot/hard on bikes) downshifted to 2nd coming to the stop and "clack clack" shut her off...brought to us, we heard it and stopped INSTANTLY...pulled valve cover (again new never touched bike) and the intake cam was 2 teeth forward from stock!
We were gonna build his bike anyways for racing, so now we just started it a few months early....but here is proof the tensioners do not work well...
Pulled head and here's your proof yamaha... sucks.
(yes its a mess...this was the second we pulled head off to show customer)
So come on Jay @APE finish up those tensioners!
