Just got myself a Nighthawk 250... anyone knows what is the standard size of the front and rear sprockets of the bike? I feel that the engine got a bit stressed when I cruise ard 80kmh. Can I up the front sprocket by 1 tooth and down the rear sprocket by 2 tooth? Will it affect the pickup and fuel consumption? Any shop to recommend doing this mod?

 

wow.. almost 5 years to get your nighthawk..

 

i got this info from a website:

Front 14, Rear Spocket 33

Tire: 90/100 Front, 120/90 Rear

Spark Plug: CR6H5A

 

i need to change my clutch plates soon as gear changing is very rough.

rear wheel bearing also gone

chain spocket looks like 3-5 years old..

 

but despite all these small glitches, it still brings me from A to B.

no leakage whatsoever.

Yep..been riding a majesty250 all this while..only recently want to try out a nighthawk Anyway, thanks for the info...

 

Still thinking of changing the front and rear sprockets to increase top speed so that the engine would not be stressed at 80-90kmh. Anyone knows where is a good shop to do this and roughly how much? Thanks in advance..

hi guys, i am sorry if i am three years late, but i have to mention that the Nighthawk 250 is nothing but a solid solid bike.

 

I have been riding one for the last 10 years and prior to that, my dad was using the same bike i have now for like 4 years making it 14 years old.

 

I started off with a japanese cb 250 and three years got it upgraded to a sport rim model from the brazilian model. It is surely a thoroughbred but an amazing bike lah..Please ask any questions on the bike. Afetr ten years, i think i should be able to answer anything or any questions on the bike.

cheers

Thanks alot bro.

Btw, my nighthawk seems to have a loose steering cone. Its like when I brake the front wheel hard or when I go over humps, the front fork made a sound and I feel as if they moved backwards abit. Could it be the streering cone bearings??

Anybody knows where is a good place to service/change the steering cone and how much am I looking at? Thanks alot!

need to check the steering cone then we can determine the extend of the problem that exist. you've gotta lift up the front end of the bike to check if the bearings are worn out.. the handle bar should not sway left or right easily if the bearings are working.

 

any normal bike shop should suffice...

the problem might be the front springs or the lack of fork oil; the front fork needing servicing.. mine is due for one already...

best to send to a mechanic to check it up..

might be engine problems- piston, lack of EO, worn spark plugs?

push and cant move- was your gear still engaged? or in neutral?

spark plugs fouled with rain water? thus the sudden stoppage

 

how did u check your bike for 'spark'? you mean checking whether the spark plug is working? can only use visual eyes to see the tip of the plugs.. can check any other way?

[I_Ride_A_Bike]

anyone has any info on the front fork springs on this bike- Honda CB250 Nighthawk?

need to know the rate, length for upgrading purposes... i only know the diameter for the front fork is 31mm..

 

thanks!

HI, Im riding a cb250 nighthawk.

Heres my situation, currently i have the disc sport setup on my front wheelset. But i would like to change it to disc spoke setup, because it provides a bigger range of tyres that i can use.

do you know if theres any wheelsets that is compatible?
