Nothing is more disappointing than buying a new toy, like let’s say a mini bike for example only to have it break after using it only a couple of times. Well, this is exactly what happened to me. After about 2 hours of use my mini bike threw the chain between the clutch and the jackshaft. In this post I will talk about exactly what happened, why it happened, and how I fixed it. <\/p>\n\n\n\n
I was out on a camping trip with my family when I decided to take my Coleman CT200U for a little joy ride. I headed off down the road in the direction of the general store. About 5 minutes into my ride, the jackshaft chain went flying off my bike. <\/p>\n\n\n\n
I took a quick look and discovered that the master link in the chain had come undone. I walked the bike back to camp to take a better look. After a deeper dive I realized that the real problem was that the jackshaft sprocket did not quite line up with the clutch sprocket or the rear sprocket for that matter. <\/p>\n\n\n\n
This jackshaft misalignment put sideways pressure on the chain, eventually causing the master link keeper or plate to pop off. Then with nothing holding the master link in place, it simply slid out and sent the chain flying off into the road. <\/p>\n\n\n\n
In my case, the jackshaft sprocket was too close to the jackshaft mounting plate. I needed to somehow add a spacer between the sprocket and the bearing that holds the jackshaft in the mounting plate. As it turns out, the mini bike already had a bushing between the sprocket and the bearing, it just wasn’t big enough to align everything correctly.<\/p>\n\n\n\n
Here are the steps I took to fix the jackshaft sprocket alignment:<\/p>\n\n\n\n
