Newcomer needs help

[keen93]

Hey guys im new to the forum and wondered if anyone can help me? Ive been riding a ybr125 for 6 months now with no problems until recently theere has been a problem that gets worse every time i ride. There is a grinding noise and feeling near the front end of the bike that only happens on acceleration and happens more in lower gears. It tends to happen on revolution of the wheel. Any idea would greatly appreciated!

Thanks

Wayne

Hi K93

You have to do some investigation before anybody can offer worth while opinions.

But I would check my brake pads and wheel bearings if the noise is coming from the front of the bike and occurs when the wheel revolves.

The list of investigative questions you need to find the answers to can be many and varied but the sorts of things you need to be thinking about are!

Does the noise come from the front wheel or back or when applying the brakes?

Does the noise happen whilst the engine is ticking over under revs when stationary?

Can you reproduce the noise with the bike on the centre stand and spinning the wheels?

If you cannot whittle the problem down to a specific area or component I would nip to the nearest motor bike shop and ask them to just give it a quick look see, They will at least be able to advise if your bikes problem is dangerous,

Grinding noises are not a good thing and they can be the final signs of component failure so if I was not sure what the fault was I would be very careful riding the bike until I had got a good idea whether it is dangerous, expensive or both.

Hope you find the answer soon

Hey thanks for your advice, figured out it was the front sprocket that gone. The retainer that keeps it on is split so the sprocket itself is loose. Replacing it tomorrow thanks again!
