Anyone know where is BM Motors in Bukit Mertajam? The shop makes BM Power exhaust pipe one??

I'll be going Bon Odori tomorrow, the Japanese Hungry Ghost Festival... Just dropped by the Penang Esplanade, looks like a big area is prepared for it.

See you all sunday morning... I can't wait to see those modded classics.

I think it's Hurricane front assy.

Ok, you don't go far... when RGV needs new shoe, I'll find you, ok?

I fart with smoke... 2stroke style.
Anyone looked at how the construction of the silencer columns in those pipes? Direct pipe with no muffler will be damn loud, muffler holes with fibre will be deep and foob-foob sound...

Sure, Post your info here... refer to Page 1...

What's that? Star newspaper?

How are you doing? Heard about it from Spayz.
Btw, do you park at multi-storey?

Thanks TryX for the photos?
My RGV is really out of the picture among these bikes... only 1 2-stroker there. You can see it at the far side in the 3rd photo.

So, when can TT or go jalan2?

need to open up everything. the symptoms are white smokes when engine running normally, though this can be mistaken if you overfill EO...

I used to riding Yamaha Sports. When I had the RGV, took me a day to learn the clutch. Gets easier once you have driving experience I guess.

Try this practise, do standing start, tarik clutch, masuk first gear, pulas minyak sampai 3k RPM, let go clutch, steady, then stop, then standing start again... until you pandai.

Takpe, pulas je minyak. Mmg ni motor CC kecik bah...

Not sure... I've not have experience driving something like that.

Saran, why you asking harrrrr? Your LC smoking like 125Z is it?

LC got electric starter ah? If you use kick starter, is it because of the kickstarter not return to original position? That could have a 'gear' sound to it... Other than that, you could be using a very thin EO? Something like 5W-30 perhaps?

so, it's the kickstarter sound then?

just to add, try to start engine without too much throttle... ya know, some folks like to brennnggg early in the morning once the bike starts when the engine is cold... it's like yanking you out of bed while you're still sleeping... not a good thing... haha...

haha, nice bedtime story. thanks.

Added on July 27, 2009, 12:39 amanyone mod side mirror one ah?

my bike use a short mirror to avoid hitting car side mirror. today i rode past a BMW 7-series, and saw the side mirror missing...

That way, when you signal, it won't blink. Right?

Bro, pomen blh pasang, senang je kalau nak pasang sendiri. Tgk rupa model, ada yg pakai nat, ada pulak allenkey.
Effect tak rasa, lbh kepada luaran je. Teori saya, to reduce twisting waktu cornering... sikit macam dengan kelebihan upside down fork.

Added on July 28, 2009, 9:39 pmWhat kind of knocking sound? Tok tok tok or tak tak tak or kraak kraak kraak?
When does it happen? Idling or high RPM?
New bike or used bike? Was the bike run in properly? What's the mileage now?

I'm thinking there should be a relay or flasher sold outside suitable for this mod, but need to re-wire a bit on the bike.
Re-wiring means change the wiring at the left hand switch to connect to the signal lights. When the switch at normal position, all lights on. If switch on left signal, activate left flasher, and likewise for right side. Doing it right also need to source some electrical connectors. I haven't know where to find this kind of socket. The mechanic way of doing this would be to stick the wire into the socket and black tape everything... Ugly and pray for no short circuit someday.

Since someone called me 'sir', I have to buka my textbook already... haha.

For the speedcalc, it's a calculator. Duh...
Engine crank + transmission + final drive (sproket ratio) and wheel size is the essence here. Since the parts here are all connected, no rocket science.

Example, 5000 rotation on the engine will move the wheel 200 times.
200 x tyre circumference you get the distance. Tada!!!

Compared to a boat engine, the maths is much simpler, because for 5000 rotation on the engine, you cannot exactly measure how far the boat moved... Itu panggil 'fluid dynamics'.

So, fishing, anyone?

***Additional talking, if you're not interested can skip. If I'm wrong, feel free to comment. This is a forum afterall.***

The difficult part of the math is the dynamic of the engine output: torque and HP.
Torque is how much 'pull' the engine can generate = pickup.
HP is max output to maintain that RPM, while all negating factors eats up the torque = topspeed.
*Negating forces = the reduced amount of air-fuel mixture at high RPM, friction, payload etc etc.

This means, you need to dyno an engine to get torque and HP, measure the weight of the rider+bike+nasi ayam tapau, to calculate the best combination of gearing suited for riding style and road condition.\
In short, highway bigger final drive ratio (17:44); city driving use smaller (16:49). Example quoted is the extreme for TZM lah.

Theoratically, you can use bigger carb, or even also install turbo to maintain or increase the amount of air-fuel mixture at high RPM, so that engine can reach unlimited RPM... until it starts to meltdown. Haha...
*There are people dedicated to break the 300MPH barrier, by installing turbo on 600cc bikes like the CBR-RRs.

Points to ponder:
1. When you read vehicle specs, why max torque is always before max HP?
2. How true is the saying: Torque wins races, HP sells cars.
3. How does a smaller cc engine out perform a bigger cc, during jump start and acceration?
4. How to balance between accel and topspeed?
5. Should I consider sprocket ratio when I change tyre size?
6. Why can we maintain at a certain speed just by controlling the accelerator leh?
7. What's the deal with high speed bearing, lightened racing parts, and all the other modifications?
