Default Replace/Repair/Adjust Chain

Hello All,

I'm the guy with the $15 motor bike that I bought at a garage sale last week. I keep snatching defeat from the jaws of victory, and I had a gumption killing moment today I'm seeking advice on.

I realized that the reason the last guy got rid of the bike was because he had stripped out the engine mounts. I got impatient, and started it before I fixed the mount, and it jumped off the frame. It looked OK, so I spent the morning re-tapping the engine mounts (a cool thing to learn how to do, I must admit). I got it all back together and found out that when it jumped off of the frame I broke one of the links. Then, when inspecting the damage, I lost the master link (grrrrrr).

Are the chains with these 50cc motors basically standard? I know I can order a master link from zoombicycles.com, but then I'd still need the replacement link. Anyone know a place I can get one of those? Should I just buy a new chain? What do you all think?

Thanks!

Cory

Hey, Now I'm replying to my own post!

I scrolled down the page, read a thread on chains, and saw a related threads section. Learned a fair amount.

Still wondering though, anyone know what kind of shop carries these 415 sized chains besides online retailers? Where would I open the yellow pages?

Is there a way to search these threads?

Thanks again!

Cory

You can go to the main page and search threads by keywords. I have replaced the chain with #41 chain. I got mine at Tractor Supply Co., 10 feet for under $15. and also a pkg of 5 masterlinks for another $2.

I went to get a #41 chain. Did not work for me. My old chain was metric and #41 is standard. It is much wider than the chain that came with my kit. And it would walk on the sprocket. Glad I didn't take off on a long trip. The chain walked into the frame of my bike...ouch...
