Hi all! I'm installing a 49cc Skyhawk kit from gasbikes and I have a few questions on the rear sproket / rag joint assembly for this particular bike: With the two rubber gaskets sandwitching the spokes the sproket will no longer actually be on the hub....is this correct? The thickness of the gasket between the sproket and the spokes is too thick to allow it to slide onto the hub. If I tighten everything down after it it's properly centered will this be enough? Also, anyone have any issues with the 415 chain rubbing the stock tires with this assembly? Or do I need to get more narrow treads? Thanks!
