Hey so while I was breaking in my bike on an old abandoned street, I noticed whenever I got up to speed (4th 5th gear) and was engine braking, the rear wheel would sorta hop up and down. Not terrible but definitely noticeable. Any ideas? Bikes brand new and it was on smooth roads, the road was wet. Also just gotta add, holy shit this bike is fast. Scary fast! I also had the bike flame out quite a bit on me, whenever doing u-turns it would stall if I wasn't on the gas, and sometimes just cracking the throttle in neutral it would stall. Most likely gonna send my TB in to injectioneeringDebating gearing, 49 or 50? I ride mainly tight trails but occasionally do long dirt road trips. I want my cake haha haven't decided for sure but I'm considering either full wr trans swap or hybrid 4th and 5th with a rekluse exp. I've searched lots and read lots of info, very helpful site.
