[Fcuk12]

Sometime skill is hard to teach... Have to take time.

 

If u wanna to make nsr150 fast

 

Change

Reeds

Stuffer

Spacer

Manifold

Carb keihin pj 32

Open pipe

Porting on cylinder and head.

 

Lik this I think is enough. If u wanna to change to class 2a or 2.

 

Cost abt 800-1200

 

Maybe i just make do with it first ba. Its NOT THAT BAD LA. can move. can pick up. can go more than 150....

next time then upgrade or what ba. haha. unlucky me lor. get cui sp. oh well....

[Fcuk12]

Anyway, service valves and power valve is it same? service carb does that mean valves are serviced already?

[Fcuk12]

Does anyone knows stock sp carb is how many mm?? as in like i got see ppl say selling what keihin 32mm carb....

 

and does anyone knows what are the stock sizes of the carb pins and jettings? like the idle jet, main jet and pilot jet? or even their own carb jettins sizes?

There are two type of valve for sp.

1. Intake valves (using reed valve)

2. Exhaust powervalves

 

Carburettor is a different component.

Sp carb is keihin pe28mm roundslide.

 

Chaning bigger carb will release more potential

 

I'm using mikuni tmx28 bored to 30mm.

Using ahm chamber pipe

Main jet 180

Pilot jet 15

[KeraKing]

wa jialat sia. maybe i go check on the jetting pins? as in the sizes.....

quite weird my fc so good for an sp...

 

Whats so jialat about dropping gear on a two stroke bro.

Thats the ways its mean to be ridden.

 

Why u keep on saying u want to check on ur jetting sizes?

Do u have knowledge about it?

Jet wrongly will cause engine seizure which will damage ur piston n block..

what japlangzi gives is good advice.

Spend some money to unleash the potential of 2b sports two strokes which will satisfy u n ur wallet in a very long time.

cos i feel that maybe its my jetting sizes too small thats y fuel keep cant flow thru causing loss of power and weird fc of 29km/litre.....

Hi guys.

Im new to the sp world...but ive a question to ask.

Anyone know where can i borrow stock foot rest for inspection? Just went VICOM and they fail me for my footrest.

They mentioned about rubber footrest.Anyone?

[japlangzi]

There is no cui (lousy) sp... Is how u look at it.

 

Standard sprocket size front 14 rear 40. Check ur valve is it jam? Change the cable at ur rc motor and near ur cylinder there. Clutch skin is it in gd condition? Piston ring loose? 2t intake cannot too much. Carb setting...

[1ape1]

alright! just nice. i got a question to ask eh! LOL!!!

 

When i am moving or riding on my SP, when about to stop, i change gear from any number to gear 2. then at the point of gear 2, i wanted to change to gear one. but unable to gear down and i hear some gear biting when i tend to kick down.

 

so i fast pull my feet up then kick again, the gear went to gear 1.

 

why ah?

 

clutch cable? housing? gear? =x

 

Referring to this )) i am a new rider too (post #138736)

[wad3v3r]

btw guys, this might sound stupid...

How fast are your pick-ups? i have tried my friends kr, and his pick up was really fast compared to mine. the sudden open of throttle has the sudden surge of pick up power without needing to drag till 9-10 rpm and u feel your whole person like kna pull back. While mine, if i open suddenly, the pick up is kinda slower (can feel the considerable difference as compared to his), and mine my whole person wont really kna pull back as much, and the bike sounds like as if it is struggling to accelerate(but still does hit high speed eventually).... My fc is 29km/litre with me changing gears at 9k rpm which is weird since like everyone here say normal is 220? or max 250?

 

my throttle isnt that sensitive as well.... kinda not very smooth when moving off. from move off till i hit above 4k rpm, the bike has like no power.

 

sorry for long post but i just wna know whats the problem here. head exploding soon as i did alot of research online but couldnt get an answer. dont wna tio carrot for nth if i jitao go to shop.

 

Hope to get some answers! Thanks in advance

 

ur answer is to buy a kr
