idle

I just built my brand new 49cc 2 stroke bicycle last week, and tried to ride it about half a mile. I'm really pretty sure it should be operating differently than this? what happens is the clutch DOes disengage and the bike rolls freely, until I let go of the clutch, and the engine starts just...

Hello, can anyone tell me what I'm doing wrong here...? I've heard from my experienced friend that: while my engine is running, I can squeeze the clutch lever to just coast and hit the brakes at the same time if i want. Yet, when i squeeze my clutch, it just revvs way up, way too much...

I just got my bike back up after a few years and it runs fine. However when I pull the left lever and stop the bike so it idles, the engine gets incredibly loud and starts vibrating hard. I've adjusted the idle pin thing in the carb in a few positions and it's the same. Any advice for getting my...

Hi, I've currently been running my bike without a tensioner because my lower chainstay is angled and I can't use one. But I've seen that the chain is getting very slack so I want to get one of the spring tensioners that attach to the gear case. Like this...

So i have a Baja Adventures 70cc pit bike. When i first start up the bike and let it warm up it idles fine but when i ride it and then stop and have it in gear or put it on neutral it dies. Any suggestions on how to fix it? I’m thinking it might be the carb. I have videos if you want to see.

So I started up the bike. Gave it speed, let go of the clutch, hit the throttle. Then the throttle became very limp. Then it wouldn't run when I started it and then it died. And on top of that now the throttle is limp and won't do anything. Anybody know what to do?

Alrighty where do I begin. I finally got my bike out of storage for the winter a month ago (it has a Grubee Skyhawk GT5A installed) after giving it the once-over twice I got it running nicely, no problems for the first couple of tanks running at a 25:1 ratio. After letting it sit for a couple...

Hi Im new as of this second to this site though i have been on browsing in the background learning as much as i can for some time now I have an engine that wont idle. It must have an air leak but i dont know where. I know i need a spray bottle and run the engine to look for leaks but the only...
