Problem with NSR150SP
-
this is normal ah.. in fact I use this RPM range to maintain speed and it tends to consume less petrol (5'th gear or 6'th gear at 4-5k rpm, should be 60-70km/h at constant speed)..
I think this happened to all bike coz last time I ride Yamaha skipper 110 cc oso like this.. -
for the turning to the right check your throttle cable ...it is properly tied ???Originally posted by toons9:hoizzz anyway since tis topic is problems wif sp i also wana bring up a prb i been having.....when i turn my handle to the right fully and slowly move my bike backwards lah wif engine off.....when reach certain part hor got tis screeching sound frm the wheel sia kns.....last time like dun have then recently keep having lor...then i move front dun have the sound only i move backwards got tis metal screeching sound....anyone got tis prb b4?? or anyone noe how to solve it?
for the screeching sound check your brake pad or brake disk maybe your brake pad worn out liao or yout brake disk is out of position
all the best -
i think the fuel needle in the carb position is rich. set it at a clip leaner ....think will solve the problem or reduce it .

HIHI
the problem arises becoz of bigger oil jet....that prevents the piston from coming up easily due to too much oil at the top....so u can either change ur way of riding or ask to change the size of oil jet...a power reels will help too,if u chose to keep the jet, u muz blow to suddenly increase ur combustion in ur carbarator, in this case , u will have a beta top speed and it also help to prevent piston jam,unlike a smaller oil jet....that have beta pickup...

i think hor... we thinking too extreme liao... wad i think is simply...the valve..
most bikes the valves open at this point if not near this point... tzm got valve...sp oso got valve...if the knocking is there after u full ball the throttle... it means.... yr yu jet is too big...pls bare in mind tt bigger oil jet does not mean it will b faster

.... huhhh huhhh.... sim ai eh mai kao....jia li tan wa pang buey gi ahuh li bo kiam wa,wa bo kiam li!! -
Yeah! U've got the answer... If u've never modified yr bike b4, leave the oil jet alone... That's the original setting... Juz tell the mech to tune the air jet...Originally posted by ^TzM 53^:i think hor... we thinking too extreme liao... wad i think is simply...the valve..

You sure your valve opens at 5k rpm?Originally posted by otacon:There's something wrong with my NSR150. I suspected is my carburetor that caused the problem. Whenever my rpm is before 4500 and after 5000, the bike goes smoothly. What happens between rpm 4500 and 5000 is that my bike will start to shake as if not enough fuel or too much fuel rushing in. So I guess between rpm 4500 and 5000, it's when my valve opens, causing this problem.
I hope you people understand what i meant. I was wondering if any NSR riders faces the same problem. Or whoever knows what the problem, please reply to this topic. -
Somewhere there lah. Anyway, i long time never ride my SP liao. Once in a while ride, got really very irritated by the carburetor.

I agree, cos my TZRR also like tt.Originally posted by LexZEUS:this is normal ah.. in fact I use this RPM range to maintain speed and it tends to consume less petrol (5'th gear or 6'th gear at 4-5k rpm, should be 60-70km/h at constant speed)..

I was just thinking if there's any newbies in the forum, have a solution to the above problem, but never see this topic and so I decide to bring this topic alive again.
Btw, what's market rate for a second hand's NSR150SP. My NSR150SP plate starts with FP. I asked one motor shop, they buying in at $2200+. I was shocked cos I bought at $6000+.

That means there's really no way to solve this problem. Haiz...
I am really sick of riding my bike with this problem. Somemore it's one of my dream bike and it turned out this way.

hi there. mi riding an old sp..
my valve opens at 7k rpm.
if u change gear at 5k rpm at every gear u wun experience the "extra" power lor..thus safer also lar..
1st gear 5 rpm change
2nd gear onwards 5.5 to 6k can change liao..
den speed about 100km at 6 gear.
conclusion---dun go so fast lar..lower gear dun nid to rev so high 1..juz up 1 gear,b4 ur rpm reaches 7k . -
Hmm...., think my SP also hav this "effect" at ard 5000rpm. CanNot maintain speed hor, but I heck care lah
Dun think it's a problem to me..., No offence hor.....
Coz I maintain my bike at 7000rpm most of the time. Then at 5000rpm, I feel my bike is telling me to open throttle abit more....
Kekekee.....
So I open loh....
I feel the more I open, the more my bike is Happy leh.......
Hahahah!~~~
No Offence hor, coz it's me and my bike.
