new sound on my ninja 250r

kimolottie_06 · July 11th, 2012, 11:29 AM

Hi guy's. I have a question. I just replaced my chain on my 09 ninja 250r. it has 16k miles on it atm. i ordered the stock chain and put it on the bike and washed the bike completely (motor and all) with soap and water with a brush. The weird thing though is after i did all that to my bike. The motor has a strange sound when i drive it past 30mph. and its similar to the motor sound of a 4-wheeler. It gets louder when i go faster. It never made that noise at all b4. Is that normal for it?? sorry ima new driver and i dont know too much about them. had the bike for 3 months now and bought it at 10k miles. also it only makes the noise while driving. i can rev the motor up standing still and it not make the noise.

Welcome Kyle!

I bet your hearing some chain noise. Check chain tightness and wheel alignment. If either one is off you may hear noises.

Yeap sounds like the chain to me too, Did you grease it properly? is one of the chain links sticking anywhere?

Could it be from the sprockets?? I thought they need to be changed out with the chain?

EthioKnight · July 11th, 2012, 12:43 PM

You should have changed the sprockets when you changed the chain (or at least made sure they were alright),..., another possible issue could also be the valves. I hear either loose or tight valves (can't remember which) produces a distinct and pronounced change in the sound of the engine and considering you bought the bike @ 10K miles, are you sure the 7,500 miles valve servicing was done by the P.O.
Just some ideas, hope you get the issue resolved

the valves i dont know about. I checked the sprockets and they were great. and i know its not the chain i got it set properly and wheel alignment is on perfect.

and i hope its not to expensive to fix. because i got to get my carb's fixed already. Gota get the needle valves replaces and cleaned up. Ty for all the help guys also.

What type of chain lube are you using? How did you confirm wheel alignment?

maybe your chain is too tight. maybe your wheels are going to fall off. maybe you just need earplugs.
