Any other way to keep the chain from hitting the tire besides getting a narrower tire, or with the tensioner? I don't want to go any narrower with the tire than it is now, and the chain keeps hitting the knobs on my tire. Sometimes when I ride it jerks kind of violently. Also, my frame is kind of damaged so using a tensioner in that spot isn't an option. My sprocket isn't concaved, and my wheel cannot be pulled more to one side or the brakes will not work.
I got lucky - mine barely hit the knobs for a couple rotation and done.I think I'm going to try and cut the knobs off, but I like the knobs. Is there another way? has anybody made some kind of a 'tire guard' thing, that blocks the chain from hitting the tire?
You want to make sure that your engine sprocket is in line with your drive sprocket, keeping the chainline straight. I use a steel rod laid accross both sprockets after the rear wheel and motor are in place. If they aren't in line you will be more apt to throw your chain. On one of my bikes I have some wheel rub, now I'm sure this will raise some flags, but I let it rub and it cut its own uniform grooves into the tire and now it runs great...Kelly"Just make sure the chain run is true."
What does this mean?
