Folks,
I think I fixed the problem with the rear jerking a bit when accelerating. I was able to find the swing arm on my JCL MP-250A. Although the bolts were not loose per say, I could turn them with the wrench. I had to use 2 wrenches to tighten them since there was a a nut on the other side. I also tighten another bolt holding a bushing from the swing arm that was bolted to the frame. Again, it was not really loose but I was able to tighten it a bit. I did check every other single bolt I could find. Now, the jerking seems to have disappeared, yay! It seems that the extra bit of tightening did the trick.
I also checked the CVT to see if the main bolt holding it was tighten and it was.
Thanks to all who provided some help. Seems my ride is now back to normal!

Thank you, folks, comments much appreciated! I'll tackle this next weekend and will let you know how it goes. Thanks to Cruiser to help me identify this elusive swing arm bracket. I should be able to find it now. I did check all the bolts I could find yesterday and tried to tighten all of them. Except for the missing bolt holding the gas tank to the frame, all other were very tight. LUKE: how can I verify the if the variator (CVT) is the problem? @jrryan: you're here too? Glad to see you around!

Hello. I was told I might get help here. For a couple of weeks now, I've been feeling that the rear of my JCL MP250-A has been jerking a bit when I turn on the gas at low speed. Someone suggested that it might be one of the bolts holding the swing arm. This afternoon, I did remove the plastics to have a better look around the engine. I did find one screw missing from the corner of the gas tank that holds it to the frame and did replace it. However, that I didn't fix the problem. I've been looking all around the front of the engine to find that swingarm which is shown on the Roketa part image here: It is part 21 on the picture. So, I need some help to direct me to find this swing arm on my MP250-A. Does anyone know? Thanks in advance! -Laurent.
