nice video and bike, the carbon fibre wrapping i nice.

 

btw anyone using K&N air filter for sp? the panel replacement type, not the open pod type. https://www.knfilters.com/air_filter/honda_nsr150.aspx

where to buy and how much? need tune carb after that? because i now not running filter, only air box and after the ovehaul and decarb my fuel consumption go up a lot so i thinking of asking mech to tune.

the K&N air filter,drop-in type.

Price around S$100.

The last time i checked for k&n filter was with Unique. Sgd$120 including installation. Need to order & wait something like a mth+- somemore. So I forego it. What i hv now is normal stock filter which is just a sponge ordered by tsk when i overhauled. Rm$80 only.

 

For carb setting, there is an air screw next to your idle setting knob (yellow star/flower shaped knob). The normal stock setting is 2 turns out (counter clockwise). So if you want leaner setting (more air) you gv it quarter turn out. But you must be careful, too lean & there will be too much heat, or you get hanging idle (idling speed can shoot up to 3-5k revs & stay there). Normal setting gives abt 21km/l or so. Mine, I lean out a bit.... abt 23-25km/l. But if always in stop go traffic, consumption will be quite bad. Sp is bike most happy on the run! haha

 

btw, can anyone tell me how hvg an air filter improves engine breathing as claimed by k&n? I would think hvg no filter is freer air flow, just that lots more dust enter the cylinder?? So filter is to trap dust only??

Hi there guys, I'm a new NSR Rider. I just got my bike and it feels a little sluggish when I throttle. Went to Unique and they said that it's due to tuning of carburetor. Do you guys know of any other place that can do servicing for sp including tuning?

 

Thanks guys. And is there any WhatsApp group for SP riders?

many factors can make the bike sluggish:

1) tuning.... too rich or too lean air fuel mixture affects combustion hence power.

2)carbon build up in exhaust....need to decarbonise. Only can do in jb. Very smokey job.

3)carbon build up around rc valve & combustion chamber.... do full service at workshop. Any workshop can do it. But I like planet motors at ubi or go to tai seng kooi motorsports, jb.

 

But also be aware of bike characteristic. How are you throttling? below 5.5k revs, the bike is rubbish. You will only get to feel some decent power come in around 6k revs. Beyond that is practically power on demand. RC valve opens at 7k revs, & opens bigger at 9k revs. So you will feel extra kick once the valve opens. Keep the bike in the powerband. quite often you will have to downshift a gear or two to really get going. Otherwise really no pick up or power. its not the same as riding 4 stroke bike, where there is power in the lower rev range. Generally 2 strokers have very little low end power. They are all about mid range & top end power.

I usually throttle normally, reaching about 5k rpm however, for me to get to 5.5/6k rpm, it feels like it needs more effort, throttle a little bit more. Different when getting to 7k, because definitely that'll require more throttle. I just want to know if it's normal to throttle a little bigger. If it's normal, then I don't think there's much problem with my bike. Just not used to it. Haha.

I search knn website, with shipping it will be about 70+ SGD, cheaper than order from shop.

And my bike running lean, sometimes my throttle will stick and go down slowly, other SP riders said running lean easier to piston jam. Dk whether it's worth it to buy the knn filter or stock on enough, ah boy say $15 for stock lol.

You mean your revs will stick & go down slowly? If yes, then that is a lean symptom. Gv your air screw a quarter turn in & see if it helps normalise things. If not, then gv another quarter turn in.

 

Yes, running lean also can cause seizure cos of heat. Petrol also acts as a coolant. So if your air-fuel mix too lean, there wont be enuf coolant inside the cylinder => faster heat build up => piston expands faster then cylinder=> seizure.

 

Ah boy only sell stock air filter only $15?? Wah! like that nxt time i better chk for parts with ah boy, & then gv TSK to install. Go for stock air filter can liao la....what for spend so much for k&n? The only advantage of hvg k&n will be its longer lasting, but since stock so cheap, replace every few yrs also no prblm. Its just to trap dust only. Ask mech to wash it every time you go for full service.

[Crazybiker]

Then I better get carb tuned soon, also my throttle response not so good. Like don't have the snappy quick acceleration from before.

 

And I'm thinking of reducing 2t intake because using motul 710 also got smoke during idle and when whack throttle. Because when overhaul the mech increase it so lesser chances of jam in future..

 

 

Btw anyone got service at project motor in Yishun before? Heard he's good in sp

[jbdoggy]

To further add to the confusion, too rich oil-fuel ratio also leans out air-fuel ratio. So lets say you want more oil, you need to jet your carb for more fuel.

 

How much your 2t consumption? I was like topping up 1l 2t every 50l of petrol before my seizure. Its now abt 1l to abt 95l or so petrol. But unlike premix where the ratio oil-fuel ratio is fixed whatever your revs. Pump is variable dosage. So it will consume a lot less at idling & consume more at higher revs.

 

I also use motul 710. Dont believe all this anti smoke formula thing la. As long as 2 stroke, will always hv smoke. Morning & cold starts definitely more smokey. All the leftover 2t from the prev ride which did not burn up all condense & settle around the cylinder & crankshaft area. The moment you start in the morning the new 2t+ last nites condensate burn together gvg more rich oil mix. After warm up, will be less smokey. The thing is better brands of 2t will hv less visible smoke (less white). Even aftr my new pump setting after overhaul i still kena nea letter for smokey exhaust=> resend inspection. I also recommend Elf Moto 2 Race 2t. This i find better then motul. Also ester synthetic. Seems smoother, & smoke less visible. But cant find in sg, only Jb. TSK recommend to me. RM$90.

 

Motul you can get cheaper if you order frm this 1 guy Iride Sg (look up facebook or carousell). $22 per pack. But if you order 3 or more packs he will deliver to your house for another $3. Motortiam sell I think abt $26-29 per pack.

[Crazybiker]

Liqui moly is good also. $22 from most seller. One guy sells $20 but no stock now.

 

It's smooth and no smoke even if whack. But that was before overhaul and using a moderate/low 2t setting.

[Crazybiker]

Damn my rear brake is dragging and need to service it. I see videos and I can diy. Just need to get the brake piston seal.

 

Anyone know the price of the seal?

[eyfeyf]

Hi anyone know any shop that do full servicing for sp? i went to many shop but all of them say difficult to find parts.

 

can anyone recommend any shop?

try project motors in yishun, he does quite a number of sp. but you doing servicing or overhaul? servicing only need to change gaskets unless they open gearbox then need to change bearings also

how to find brake pads suitable for our bikes ah? i'm thinking of changing to semi sintered pads for more braking power and less brake fade. but i need to know the model number and such.

 

stock for rear is : 06435-KW6-841

front : 06455-KW6-844

 

but aftermarket ones how to find? need to manually check each brand website?

[jbdoggy]

Im currently using Vesrah high performance organic pads. Very good stopping power & good feel too!. The ones im using is same model for ninja 250.

do you have aftermarket caliper as well?

Nope. Still stock. No point spending so much to mod your calipers la....unless your calipers are quite gone case. Frm my own experience riding the last 2 years, the stock calipers are already very very good!

 

If anything, better to spend $$ on a good set of pads (not to say stock pads are lousy). organic, semi sintered or sintered... tk your pick. Just know the pros & cons of what you decide to buy:

 

Organic: Cheapest. Not as much stopping power as sintered & wears out faster. But provides very good feel & does not wear out your disk as quickly as sintered.

 

Sintered: Most expensive. Best stopping power. Not very much feel & wears out the disk fastest.

 

Semi sintered: Its the in between. feelwise more then sintered but less then organic. Stopping power more then organic but less then sintered. disk wear faster then organic but slower then sintered.

 

For me, feel is very very important... hence i chose a high performance organic. An upgrade from stock.

 

 

but aftermarket ones how to find? need to manually check each brand website?

 

Can go to any mototiam & ask. Motoworld also sell - Mostly SBS if im not wrong. But also depend on if you have a particular brand in mind or not. My Vesrah pads was what they had.

hey guys. recently my friend was riding my bike at around 120km/h and he did a sudden brake without clutching in. the engine died but when i try to kickstart it, it does not have any compression. does anyone know if its the rings or the block or piston? i didnt have time to take apart to take a look at it yet. thanks in advance.

piston seize Liao, need to open up and see the extent of damage. Might be able to save the block but confirm need to change piston and rings.

 

He brake because of other vehicles or what?
