Sounds like your chain guides are out of line or your speed changer is not lining up where they should be. Your chain is not running straight on the gears. Either that or you have a bent sprocket.

How do i fix the rear sprocket on my huffy rock it bicycle

on all single speed bikes, it has been my experience, that chain tension is the reason for the chain to come off, try tightening it again, since this seems to keep happening the chain may be stretched out now and replacing the chain and getting it tight should solve the issue.

I have a Huffy bike with a 48cc motor on it. The chain hits my fenders and now keeps popping off

which chain is falling off. the one from the motor? if so check to make sure the sproket (ps i cant spell) and gear fom motor is lined up. on mine i remember having to flip the rear sproket. are you using the chain tenchiner pulley? i think the one that comes with the kit dosnt have a deep enough gruve. i got rid of it all together, and just made the chain fit with like 1.5 to 3 inches of play. ive seen people use the tenchiner from the rear shifting gear on a mountain bike. thats what i suggest. if its the chain from your pedals thats falling of the the guys from the bike shop are messing with you or the alined the wrong chain. or maybe you need to resize the chian they just got the wheel straight.

How long does a chain normally last on a sport bike, katana 600,

It all depends on the quality of the chain and sprockets, how it is looked after and how the bike is ridden. I have known them last from 25 minutes to 10,000 miles. If you replace the chain you should replace the sprockets as well ( the chain will last longer.)

As "roadmaster' doesn't really narrow it down much perhaps a generic web search for "chain falls off bike" would work for you. YOU can see your bike. We can't even tell if its a single- or multi-speed.

How often should i oil the drive chain and clean it ? When must it be replaced?

Use commercially available chain lubricant to keep the drive chain from ever running dry. Usually it will be necessary to lube the chain every 200 to 500 miles, depending on how hard your bike is ridden and the conditions it is operated under. Chain lubes available at your local motorcycle shop are far superior to using any other type of lubricant. They are formulated to not fly off and make a mess of your rear wheel, clothing, etc.

If given decent care, you can expect your drive chain to last 10,000 to 20,000 miles. Lubrication and proper adjustment are the keys to success. Ordinary cleaning is not necessary - except for off road bikes.

It is time to replace the chain when you can lift the chain from the sprocket and expose anything more than about 1/2 the length of any tooth on the sprocket.

We have an 18" boys huffy bike and the chain keeps falling off. How can I repair.

If a single speed bike loosen the rear wheel and pull it back away from the pedals to get the chain tighter

If it has multi gears the arm hanging down has a ser screw that will need to be adjusted to align the chain to stop at the last gear

Chain keeps coming off rear cogs when you stop pedaling, and when you change gears , Have had bike to bike mechanic twice to fix the problem to no avail ! Alignment of rear derailer has not solved the...

Coming off which side ? - outside toward the frame member or inside to the spokes.

You should avoid using the small chainring and small cog combination which is silly on the one hand, damaging to the drivetrain and usually results in a lot of slack chain dangling down between the derailleur and the cranks.

Here are instructions on how to set the limit screws which determine the physical end limits where the derailleur can lead the chain.

Instructions for using gears on 12 speed Mesa runner

Not familiar with the exact model of bike but normally you start riding in a low gear. As you wish to speed up or find it easy to push the pedals just change up in gear and keep pedaling and the gear chain will move to the next gear cog. The secret is to keep pedaling when you select a gear either up or down and the gear will change. Hope this is of benifit.

Adjusting front derailer

Typically adjusting the front derailleur is a matter of adjusting the two adjusting screws on the derailleur. So turn the bike upside down. It should sit on its seat and handle bars. Find the two adjusting screws one will prevent the derailleur from traveling too far out preventing the chain from coming off. The other screw prevents the derailleur from traveling too far in keeping the chain from falling off that way. Now once you have found the screws slowly start turning the pedals like it was being ridden. Move the derailleur out as far as it will go if you see the chain is about to come off adjust the screw. Do same for inside screw. Now move the back derailleur all the way in and retest front derailleur, repeater with rear derailleur all the was out. Hope that helps. Oh, the back derailleur adjusts same way.
