Twist and Jerk By trailheadmike (Read 372 times)

I am still rebuilding my scooter from a horrendous pothole incident I had in early December. The hole was so deep that not only did I bend my rear rim beyond repair, it even cracked one of the three spokes. It also caused some body panels to break and some to actually shear off. I replaced the rim, and also replaced the rear bearing which was frozen, and now I'm working on the body.

Here's the thing - I find now that when I'm riding and then accelerate, there is a slight but noticeable little "twist" or "jerk" in the handlebars (to the right if that matters). Same thing happens when I'm at speed and then back off the throttle. I wonder if I'd even notice it if the scoot was new, but having ridden for a long time its definitely there. All else is ok. I was wondering if I had bent a front or rear axle, but I can't tell visually. Thought I'd throw the question out there before I start pulling everything apart.

Its a Vog 260 with a Linhai engine. thanks in advance all!!

Check your motor if it is a little loose or motor mount broke the torque will create a little jerk.
But something has a little play for it to happen when some torque is applied.

Funny you should say that, because there may be more play in the rear wheel than there used to be. I am not sure, because I don't remember what it was like, but it seemed like there was more than there should have been. Thing is, I have all the spacers that there should be, and the wheel was right off the same bike, so I don't know how to account for extra play. Hmmmmmmmmmm

Mike is the bearing in the swing arm seated where it was before ?

I'm not sure on the 250cc is there a top cross bar attached to the top of the engine , then to the frame ? On my 150cc the bolt slipped back and the cross bar on one side was loose . I dicovered it when I was backing between 2 cars when the rear wheel hit the curb I got a metal on metal clunk . The bolt was shot so was the nut welded to the frame . I got a longer bolt same thread . I tapped the nut then ran to bolt through then with the extra thread sticking out I put another nut .

Hold your rear brake tight push and pull the bike foward and backwards and look at where the play is .
