Hey y'all just got the eBay engine kit on my walmart 29 bike. Since it didn't come with instructions I had to search and search. What oil do you use for these little engines. The chain did come off the sprocket once last night, I think it was wobbling right and hitting the rear motor mount, I grinded that down. The chain idler, it still confuses me. Seems like the chain has to much movement around there. Well I will post more in the forums, we just had monster tornado cut our county in half. Thats the reason I ordered the kit. But I must say it's really cool.
