Hey guys,
I've got a mainly stock '14 wrr and have recently begun feeling/hearing something while in 5th/6th gears, going heavier on the throttle on uphill roads (mid rpms, around 90+ kph)
It's like a low rumble/vibration that I can hear slightly, but feel more than hear, kind of comes and goes, like a droning sort of feel/sound, but more consistent while holding mid/high rpms at high speeds up hill.
I'm guessing I've been noticing it since changing the rear tire a couple months ago.
My chain is tensioned right around 11/12mm from swingarm at measure point.
Regarding the tire: It's an MX tire that is not DOT approved (a mistake I will not make again on this bike, please no lecture
..the knobs are almost worn down now.
Any thoughts much appreciated!
