BH service I forgot how much he charged. but his service is the best I've seen, super damn clean. After service, the engine oil use liao 1000km still clean, end up I can travel 4000++km before changing EO, lol.

I've ordered a new batch of Royal Purple, but the cost price increased a lil, due to pos malaysia. all becoz of our gamen, increase petrol price. #&$*(!#@

+RM1. 1million postage gamen earn 1mil ady, ($(!*$#


when you gao tim the airflow, can reset carburetor and install adjustable CDI, ignition coil and firestorm booster to increase the low rpm torque. Mid rpm BH pipe will perform slightly better, and getting better n better all the way up to high rpm.

If you still feel the lack of low end torque, can change the manifold to bigger one, sure your low end and mid range sui sui, PLUS, your high rpm just drop a lil. (this is my current setup).


yes, if you play drag, usually accelerate at high rpm. BH custom pipe sure feels better than standard. As bizzy said, no ppl play on the road using low rpm one la... pulas sure at mid to high rpm


*side note: my fren js back fr oversea. I'll arrange the firestorm booster meet up session. Only 2 units available for grab.

yeee hawwww...
i missed my wild horse

thanks alex
yea, i m using PWK. BH is able to make a choke cable for me, so my bike can be choked, lol.


@Hiruka
Yes, I'll let you know when I balik PJ. I am usually driving, and my bike will be in Penang. If you are free, come join us at Penang TT la

btw, judging from the road you are taking, I have a different modification advice for you

1) 60mm block piston set
2) custom pipe + enlarge manifold.
3) 15-36 Sprocket set 415SSS
4) 28mm Keihin carburetor (PJ size 40, MJ size 120)
5) BRT dual band (it is adjustable, set it to 29 or 30 degree BTDC)
6) remove air filter

*** 7) port and polish if possible (need a pro pomen, if cant find, better stick to original)


are you wondering why I can give you quite precise setting? because this was my old setting on my 60mm engine with standard cam and original porting size.

The custom pipe + enlarge manifold I can ask BH to do for you.

Added on July 27, 2010, 4:38 pmhaha, means he can even use 15-39 standard sprocket to match the new engine power.
haiyoooo, i gotta be patient. luckily still got kelisa to play. I ady got new settings, and cut the cup to a funnel ady, wahhahaha. It is a lot better than last saturday

S-flow tak boleh pakai unless you using auto gear la. ytd I js killed a wira 1.3 modified, he one person and my car got 2 ppl


you are welcome bro. I js wana let u know the theory behind the modifications. I know how to talk experience only, but my hands on is very sux. pomen take 1 hour to finish, maybe i need 1 full day, hahaha.

If you can find another bike to use for 3 weeks time, perhaps u can post your LC to Penang, I can handle the whole modification for you, and we have so many Penang members here to test ride for you. It definitely costs more than RM1500, but imagine this, your bike will be modified personally by an ex Suzuki cubprix team manager who won a few champion before.

Then... you take bus to Penang, pay the shop and go for TT session with all of us here. After that, enjoy your ride back to KL


I like Aprilia 125, but it is street illegal... 125cc @ 30++ bhp, anyone??


can, but very expensive. about RM20 per piece if i recalled correctly.

engine installation is about RM100 i think. BH selling FZ block + piston + installation near to RM4xx. You can ask him and see if 4xx includes installation or not.


what are the things that need to be considered? mind to share?

time to use yoshi, kekeke

BH knows what to be done on FZ setup. I already mentioned, changing the block/piston alone will help a lil in performance only. You get more torque at low rpm, but mid rpm onwards, if there is insufficient air-fuel into your engine, the gain is very minimal. For example, u may get 12bhp @ 7000rpm with 135cc, and u may get 12.xbhp @ 6000rpm with 150cc, but from 6000rpm and above, power starts to drop becoz the exhaust pipe doesnt allow more foul gas to flow out of engine.


Share my experience to you:
right after I do port n polish on my kelisa, I use powerzone 3-2-1 custom ported exhaust header, but the mid pipe, muffler and tail pipe still standard. The whole car feels like a 660cc kancil, no power at all, even worse than my original port size.
but after I custom make the whole exhaust system, I can keep up with a modified wira 1.5L with 1st, 2nd and 3rd gear.


So, before changing the engine, allow more airflow in and out of engine 1st (change carburetor, exhaust pipe and open up the cylinder head port size), else the gain is really really minimal.

clak clak clak?? at what rpm?

if high rpm, definitely it is CDI cut
for your case... have to test it out with my body first

btw, the firestorm is available. My friend will pass to me in a few days.

fire storm 1st, limited units available. ignition coil can wait ma.
Royal Purple ady arrived at Pos Laju today. It will be less than RM50.


if the straw is very small in diameter, how hard you blow the air into it also useless right?

it's not too lean or too rich on oversized carburetor. It's about airflow speed.
In a super big carburetor, there are a lot of air molecules. molecules have weight, if the engine does not create enough vacuum to suck the amount of air molecules along with the fuel, the engine will under power.

32mm carb + 135cc - power is even worse than original carb!!!
32mm carb + 150cc - die also !
32mm carb + 166cc - come and race with my 28mm + 166cc and see can win or not?


In order to have bigger vacuum, we need bigger cylinder head port size, valve size, bigger engine block and piston (as in increased CC), and also a powerful exhaust system that can pull more airflow out of engine.


28mm is suitable for 176 - 200cc
26mm is suitable for 151 - 175cc
24mm is suitable for 125 - 150cc

2 stroke may have different rule of thumb. I am talking about 4-stroke NORMAL street riding. Racing 4-stroke can jump 1 size bigger, as the engine is always high revving. (where got ppl racing with low rpm one )


My bike is using 28mm carb with 166cc. The low rpm torque lacks a bit. So my current project along with the engine strengthening is to customize the air intake. Maybe I'll buy another indian cup and make one more funnel + a longer ramp pipe before it goes into the carburetor intake.



FZ exhaust cannot fit, as the pipe manifold is longer. We can take the tail pipe of FZ (as it the catalyser part) and pair it with a custom manifold of LC. But... are you going to spend RM4xx to buy an ori FZ pipe, cut the tail, and then spend another RM80 to custom made a manifold?

Added on July 28, 2010, 10:21 pmcompression pin is just to increase the engine compression ratio slightly. FZ block can remove, bcoz the engine itself has lower compression than LC block. Firestorm is a spark plug booster better than stromberg.

you are welcome. FZ camshaft isn't good too. It is a 270 degree cam, a bit on the high rpm side.
I'd suggest to use original cam with custom pipe + custom manifold. If not enough, the ori cam can be customized to give better engine powerband.


all the best in your studies. Faster get good result and back to the TT.


Firestorm is >RM100, but comes with lifetime warranty and money back guarantee if you feel no power increase at all. (I need to run in abt 300km to feel better effect on my Kelisa)
Yea, it is harder to start with compression pin removed (my bike also like this ma).

me nvr tried them before. its better to ask apek

24mm for 135cc, 26mm for 166cc (60mm). Since you travel more highway, 28mm increase top speed a lil and sacrifice some pickup on busy traffic.

the custom pipe + enlarge manifold will still rust when the black paint is burnt, unless you chrome the whole pipe.

port n polish is engine related, there is a lot of details in google.



btw guys, this is the advantage of funnel:

hehe, what u wanna mod bizzy?

@Spayz, too much air makes the mixture lean, prone to engine kabooommm. Let BH help you reset again la

@Devil, engine without modification use back standard size. I have huge power at the rear wheel, so I use 90/80. Front still 70/90

welcome bro.

its ok... kaboom liao got reason to upgrade to 65mm engine.

hahaha, this is the real thing.

you mean the chrome one ar... yea, gotta use different material that kenot rust. sure $$$ like hell. not worth la.

1. When you have good airflow and PnP, surbo is useless. In fact it degrades your performance, when the fan cfm is less than what your engine requires.
2. I am using racing ignition coil + spark booster

mushroom head + restricted exhaust = 1000W power supply to run Intel Atom and built in graphic... <-- no point.
standard carb + standard filter + custom pipe = 300W power supply to run Intel Core i7 and Radeon 5870 <-- sucked up.

In short, air intake and exhaust must match the engine capacity and port size. We cannot do one single entity only. So for performance modification, any changes in air filter/exhaust/pnp/engine size/carb, we need to reset the whole thing and match nicely.



This is the last 4 firestorm on hand. 2 are booked, left 2 only. Lets say bizzy and you take one each, then boh liao
