Hello All, first post!
Need some experienced biker help with my KSR Moto GRS 125cc bike.
I start up and warm up the bike with the choke out and set off - everything OK -
2 minutes down the road there feels like friction on my back wheel, slowing down the bike, almost like I am braking. The revs on the engine start to slow down slowly even at full throttle. At the same time the back wheel will not turn at all and starts locking up. I sit at the side of the road for 2 mins with the choke out. I rock the bike back and forth after a while until the wheel freely moves again.
I can now continue down on my way, although with the choke slightly on, as when the revs drop below 4k when I twist the throttle it jerks the bike forward before engaging.
Anyway, I am wondering if anyone has a clue what could be going on. I have ridden bikes for a while now and I am completely perplexed!
Thanks in advance,
