A 415 is my next move. I haven't busted a chain yet, but the bound-up so bad they were trash. Out of 600 or so miles, I'm on my third chain. I also don't like the back sprocket. It's a piece of junk. And the way it mounts to the rim, just isn't working. I don't have the means to cut the center to fit the hub right, so it's just kind of floating. And with my daily driving,.. well, it just wasn't meant for that. But some local guys have started a gasbike shop, and they've been great at helping me through this. They had their own sprocket made, and it's heavy duty and really cool. So for about $45 they'll set me up with a really nice wheel. SpookyTooth in Arizona sells a REALLY cool rim with a band break for about $150 and that's what I really want, but I just can't spend it right now. Their sprocket is bolted to the custom hub, not floating on the spokes. I also don't like the clutch lever. It's got to go. I plan to get a clutch lever off a small motorcycle. And I need to tweak the carb a little. It at least needs a better spring inside. All in all, I'm really happy with the bike. It gets me where I want to go, and it's fast enough for my lifestyle. I sold my car because this is all I need. No registration, no insurance. I'm onto this gasbike, and I'm not giving it up. With the Wald folding basket's, I'm good to go. This little 48cc anglefire doesn't always like the hills we have to take, but it still does it. If I lived in a flatland area, I'd really be a happy cruzer. I'll get some pics up of my cruzing route soon.
