I also have the same problem... vibrating handlebars.. is it just normal?

 

not much of a solution. either got below or right above 7.5k RPM

 

Do u guys think using shell V-power on our bike is overkill?

if u r into performance, then go ahead. if it's just for normal riding, wouldn't 92 suffice?

[d0n]

hi fellow cbr150r user. today i just took over thisisme's cbr.

 

just a question, where to service bike regularly? i stay at sengkang. probably somewhr near me and my fuel gauge needs replacement too

 

welcome racer~

u can ride fast...but always ride safe!

 

hello lao jiaos..

need some advice

bike cannot start, i've checked the following:

1. tank got petrol

2. battery still strong

3. starter motor is working

4. spark plug got spark

5. fuel pump (i think) got suck

 

push start also cannot..

 

what else to check ah?

do u guys have any idea whats the problem?

how to check whether the fuel is entering the cylinders or not?

 

thanx a lot

if even push start doesnt do the trick, think we can isolate the issue from electrical components.

so it's prolly down to fuel or tuning.

fuel contaminated with water?

choke cable is accidentally pulled?

carb contaminated/choked?

guys. yesterday was riding at 6th gear at 6 rpm. suddenly it dropped to 1 rpm and then increase back to 6 rpm with some jerking. Is the clutch plates worn?

 

i suppose when clutch plates slip, the rpm shoots up cause of temporary disconnection between the 2 plates, i.e. as if u open throttle during neutral gear.

 

when was e last time u did servicing like changing spark plug?

 

how much does it cost to replace the clutch plates? wanna roughly know so will not kena chop~

 

er..just before u jump to conclusion that clutch plates are worn, maybe u can consider checking for other symptoms first?

[ashiem]

hi guys. have any of you guys have problem with heavy vibration of the handlebars when your bike goes over 7500rpm? is yes pls give me a solution cos im on the verge of changing my beloved bike. thanks alot. any tested and proven bar ends? or methods that successfully reduce/eliminate the vibrations?

 

on a daily basis ride, its normal for this bike to vibrate (quite power vibration)

 

from 7k rpm - 9k rpm. well, i figure it out, its either u go further rpm (over 9k rpm)

 

or below 7k rpm to get rid of this problem, ie : if u con'd to ride with this vibration, eventually, ur coversets will crack, n TRUST ME, IT WILL CRACK!..

 

solution is, either u ride with the correct rpm OR, get a freeflow exhaust....the exhaust kills the vibration least 50 %, less vibration i predict, well, thats what happend to me..haha, mine had less vibration after i slip on the free flow exhaust...

 

my twenty cents,

Quite recent. close to 2 months ago. did servicing such as changing of spark plug, engine oil, valve clearance etc. so far i've experienced around 2 clutch slips.

 

 

emm. other symptoms such as?

which freeflow exhaust did you get?

thanx.

Spark is firing so next logical step is to find out whether fuel is entering carb n cylinder or not.

Hmm but never opened 4stroke carb before.

Is it similar to 2stroke or is there any difference to take note of?

[ashiem]

performance exhaust CF-V2

 

best aftermarket exhaust rite after the MORIWAKI for cbr150

 

ps: they dont have yoshimura for cbr150, indeed, the MORIWAKI japan r best for cbr150

 

this 1 im using is the CF-V2....performance wise...2 THUMBS UP!...

Carb is almost the same mah. You open up the carb and you will see the float chamber. Remove the float to see if there is any left over fuel.

 

if no presence of fuel, it suggest that fuel are not fed into the carb.

 

A picture of a carb being open up with the float:

* Above diagram is a NSR150 carb.. But roughly is the same for CBR150 carb.

I agree with Don on this matter. If clutch slip, rpm should rev higher instead of lower.

 

Is it possible for the SP to mis-spark for a second?

Have u tried push-start as suggested by Don? If push-start also cannot, i believe your problem is magnetic coil. CDI does not spoil easily, Will.

ok many thankx.. ups for the diagram.. hee

hmm if the magnet coil spoil, can the spark plug still fire?

because i've check the spark plug and it fires.

Coil spoil, spark plug will fire irregularly or not fire at all. Since your plug fire, couldn't be coil problem

hi guys, i am planning on getting a brand new cbr150r out but none of the shop i check with have brand new set to sell. is there any shop out there i can look into?? i had check with bike production, mah pte ltd and Hkl

Quite recent. close to 2 months ago. did servicing such as changing of spark plug, engine oil, valve clearance etc. so far i've experienced around 2 clutch slips.

 

emm. other symptoms such as?

 

symptoms like jumping of gears after u have engaged gear. e.g. gear jumps from 2nd gear to 1st gear after u have engaged and clutched out.

 

another so called test of worn out clutch plates is when u engage gear 1 from neutral gear, whether does the bike jerk forward. but note that this test may produce wrong result as having improperly adjusted clutch biting point will also result in bike jerking forward.

 

in a very bad case of worn clutch plates, the bike needs to rev higher in order to achieve a certain speed. e.g. before, 90kmph at 6k RPM. after, 90kmph at 8k RPM.

 

based on what u have described abt sudden drop in RPM while maintaining throttle, it seems to me there is a possibility that it could be due to fuel or electrical issues as well. just dont want u to spend money for nothing.

 

thanx.

if i were u, i will just try out change of spark plug. if this fails to correct e problem, will tow to bikeshop. main reason is that i feel spark plug is one of the more likely culprits and it's cheap to replace anyways. if it still doesnt solve the problem, at least i know i can safely eliminate it as the cause of engine not starting.

 

im not gd with meddling w/ carb components. but i do know that unless the carb has been tempered with, if not, it probably wont have gone as haywire as to render a A/F mixture bad enough to not get the engine started one bit.

 

fuel flow wise, quite unlikely as well unless the bike has been parked for super long time when all the rust, dirt, water, etc could have caused major blocakge in fuel delivery. rocking the entire bike (along with the fuel tank) can probably stir the contaminants abit letting more fuel into the system. but if the engine cant start one bit, then maybe it's due to other causes.

 

let's not rule out xbfish's suggestion abt spoilt CDI also~

[d0n]

hmm if the magnet coil spoil, can the spark plug still fire?

because i've check the spark plug and it fires.

 

if coil totally conked out, then spark plug wont fire. but if coil is faulty, as in it produces insufficient or inconsistent current, then thats when it's hard to detect. same applies for the spark plug. it may give a few sparks when u test it. but sekali u put back into the cylinder the thing gives a weak spark.

 

so far i kena a few stunts from my cbr150 after abt 4yrs of ownership.

1. choke cable kena stucked open, so engine cannot idle properly after warmed up.

2. fuel pump faulty, so i see the rpm reading rollercoaster up and down when i maintained throttle. no amount of idling adjustment done can produce consistent results.

3. spark plug foul/fouling. engine cannot start most of the time. but after repeated cranking for 5min, it decides to work again. but i need to maintain 5k rpm and above to prevent engine from dying off. replaced e plug and all is fine again without having to even re-tune a/f. case of kena malfunctioning spark plug?

4. water contaminated fuel. have to rock the bike/fuel tank + open choke + full throttle then managed to get the engine fired up.

5. contact points at ignition key switch broke and short circuited. totally no power supply to bike (no neutral light) unless i turn the handlebars at certain angle.

 

hi guys, i am planning on getting a brand new cbr150r out but none of the shop i check with have brand new set to sell. is there any shop out there i can look into?? i had check with bike production, mah pte ltd and Hkl

try this shop called de xing.

i recently heard from a fren that they quoted him $6k for cbr150. maybe u wan to call & check w/ the shop. price may vary cause of age, affecting insurance premium, etc.

i have no experience buying from de xing. so no reviews from me on them.

lets chat in pm mode i assume...much easier..

[chipsmore]

hi bros, may i ask what is roughly the ideal rpm u guys shift gears up? i scare i might rev too high for my riding style. (for normal travelling.)

[ashiem]

according to manual book

 

1st gear = 10.5k rpm

2nd gear = 10.5k rpm

con'd until 6th gear

 

but mine, this is what i did to my bike, as THE DOHC system are build to sustain high rpm without error, compare to SOHC bike system

 

1st gear = 11k rpm

2nd gear = 12.5k rpm

3rd gear = 13k rpm

4th gear = 13k rpm

5th gear 13.5k rpm

6th gear = maintain redline

 

i tested with these rpm, i was able to clock at 170kmh on tangkak highway, my sprocket adjustment was 14-42
