Series of question of mods.

[harun1991]

Hi wanted to ask, cus recently went to my mechanic and ask what are some mods that i can do to my sp to make it faster as in terms of performance wise.

 

He said that adding an airbox would increase by 20-30km/hour. I was kinda blur because his explaination is abit too chim for me, any bros wanna kindly explain to me why does adding an airbox to my open-ported SP would increase the speed?

 

Also another question, is using revtec/power-abuser/hotwires nology all this good for my bike, as in terms of performance wise cus have read good reviews on power-abuser and thinking want to get it.

 

Another question is what does a brake pump(rear) and a water pump do? kinda lost.

Bro save the money,change to a bigger bike...

 

Brake pump (rear) refers to ur brake pedal which is also called a master pump(brake pump),upon pressing the brake pedal,brake oil is pushed to operate the slave cylinder which is your brake calipers.

 

Waterpump is used to create flow in your cooling system.

 

Go to the library or google bro,pic up books on automotive learn more.

i think he meant top speed wise. ("He said that adding an airbox would increase by 20-30km/hour.")

 

things required for engine to move(combust)

AIR + Petrol.

 

 

bigger airbox means more air which means if u mix with more petrol, it gives better performance.

 

 

revtec/power-abuser are actually voltage stabilizer; they "boost" to give a constant or higher voltage to the sparkplug which burns more fuel as it is stronger, thus increasing combustion which also means more performance.

 

im not sure about hotwire nology. but i assume its meant to boost ur electronics.

wow guys thank u both.

Get a big bore kit and then have the block & piston ported, your crankcase flowed, a larger carburettor, larger main jet and a better exhaust system (full system, not a slip on end can). Mind you, your fuel consumption will be quite high after getting these done.

You could use a cone filter instead of an airbox too. You will loose out some bottom end power but there is a gain in power once you pick up speed and are higher up in the rev band.

Change your sprockets for better acceleration or top end. It's either or for this. Lose the top end for acceleration or lose your acceleration for top end speed. Personally, I'd go for a larger front sprocket and have the acceleration because top speed is kind of pointless on Singapore roads.

I'd suggest you save your money and instead get the bike back to peak stock condition first. Different modifications work together to give an overall improvement in performance, and must be considered together. Simply doing one thing alone (e.g. big bore, pod filter, porting) will not yield good results.

 

You need to really understand the mechanics of each type of mod, and decide what you need/want.

 

If you use your bike for daily commutes, having a fire breathing top-end rush monster will make your daily ride miserable. Generally speaking, race bikes make piss poor commuters.

Moral of the story, More speed more petrol. Best is turbocharge >,

Beware of carroting. Never trust your mechanic or anyone else to suggest "performance modifications". You won't know what their riding style is. Every rider has different priorities in specific machine performance and handling... even sound and feel.

 

Airbox is not a "performance enhancement" and will not magically increase the top speed.... that's because they're more or less standard equipment these days. The stock SP's intake integrates a pair of ram-air ducts creating a low-pressure "force inducted" effect on the intake at speeds above 100kph. This is on the STOCK bike and Honda's engineers have had millions of dollars, and all the time in the world to perfect the STOCK SP, which gives you a balance of performance, reliablity and ease of use (accessibility of power).

 

IMO, mastering the stock bike is the best way to "tune" it. Ride it for a year, then another year. At the end of it all just spend $20, change one part and there you go, perfectly tuned SP. Don't spend a few thousand bucks on a small bike. They won't survive the abuse long enough to pay off! Minor changes such as sprocket size selections create a big effect and cost little. Good maintenence practises also means you can ride like a hoon and never suffer a breakdown. In the everyday commuting "race", peak horsepower is usually never used. You want torque, acceleration instead.

 

I would recommend following @ulysses_sc advise because he is right on the money. Look at his riding experience!!

 

If you want a higher top speed, well, get an RVF next time

for SP i think its kinda pointless to over-mod your bike in the name of performance... at the end of the day its still a 150CC engine so there is only so much horsepower u can generate anyway... even with ported block and larger carb, you may be able to clear meter.... but all the ppl at the petrol kiosk near you house will know you on a first name basis because your fuel consumption will increase drastically...

 

things like power commander, rev tec and top range air filters should be reserved for larger cc bikes... save your $$ on your SP and spend it on your 2A or 2 bike

[stoner]

Well... Before thinking of performance.... Think of handling 1st.

 

Most Sp on the roads now are getting on with age... My humble questions to you are:

 

a. How are your wheel hub bearings (Both front and rear)?

b. How is your Bike frame? Any cracks due to stress or pass incident in which you have no knowledge off?

c. How are your brakes? Are the master brake pumps doing well to "stop" you?

d. How is your cone bearing?

e. How is the compression of your block?

f. How is your radiator pump doing? Any over heat? Been serviced?

g. How are your tires?

 

Well, I have just listed a few items that comes to my mind with regards to Bike Handling... In regardless of any bike (big or small ~ in terms of CC), please look into your bike handling 1st.

 

I have seen too many "Trick-Out" bikes... running on "Tread less" Tyres not because they are slicks but because so much $$ is spend on "Tricking Out" their rides and having no $$$ for Rubbers...

 

Work out your $$$ and ask your self how long you intend to keep your current ride... At times, it's better to have the bike at peak handling condition than having a speed demon ride with rubbish handling in which could sent the rider to Never Never Land...

 

Sorry if I sound like a wet blanket, but without Control / Handling....Speed is nothing...

 

Just my $0.02 of thoughts...

 

Cheers!

You're absolutely right :thumbs up:

 

I have been occasionally called upon to inspect used bikes for purchase by other forumers and one of the sad things I notice, sometimes you can see a very nicely restored SP with a nice inventory of "power" modifications but with one fatal flaw.

 

The brakes are literally, non functional! Even scarier, I had to re-tune the carb because it was setup for top speed runs and the fuel economy was atrocious. Way over-rich and unstable, and it has 'worse than class 2A' consumption.

 

Just imagine how scary it was for both of us. Here we had a fast bike that possibly cleared meter many times judging by how everything that can come loose, did so. It does regular top speed runs.... without the ability to stop. Don't do that. Ever.

 

To readers: Remember, Porsches are famous for their performance not just in terms of power, light weight and handling... they typically have excellent brakes that can generate more horsepower than the engine!

SP top speed 180km/h? is it accurate??

add an airbox +20-30km/h = 210km/h top.

a bike which is light don think is stable at tat speeds...

i rather upgrade to a bigger cc bike...
