Yeah, i agree too. I wish i have the money to buy the FZ 150i block and piston, all the fuel injection system set and put it in my 135lc :twisted:

Hello guys, I did a little bit of googling, referred to the service manual and came across this site, Link Both the parts that you mentioned, are actually two different parts. Needle jet are inserted from the bottom of the carburetor while the pilot jet from the top. According to the...

The next best in terms of what? performance or fuel consumption? Yamaha Nouvo scooter definitely suit your father.

Diverting back to the topic, which is on how to modify this 135LC to match 125z and rxz. Assuming this is street tune, bigger displacement is the way to go. Bigger valves with custom camshaft to suit the increase displacement. Highest engine compression ratio possible on your local gas pump.

Maybe he based his opinion by using the following theory. Two-stroke engine, one power stroke for every engine revolution while four-stroke one power stroke for every two engine revolution. So, to match the power output of two-stroke bike, he doubled the four-stroke engine displacement. I...

What he mean by that is, the ignition timing is set too advance/early.

I don't agree with the idea that is cooler is better. The thermostat will switch on and off the fan to maintain the engines temperature at the 'correct' operating temperature without overheating. Meaning that at 'correct' operating temperature, the engine produce maximum power by compromising...

Huh, that is the chinese copycat version of yamaha bike. That things don't deserve to be called a bike!

High octane fuel have octane rating RON99 and above. Both the fuel you mention is the 'normal' fuel, used by majority road user.

CR Here we go again. Hawkey135 method is simply to increase engine compression ratio. The higher the CR, meaning that the fuel is compressed more, thus more power generated and cleaner emission (CR = volume of combustion chamber when piston at TDC divide by the volume at BDC). Another method...

if singapore version have it, then we Malaysian can get the whole part needed to the conversion from carburettor to EFI from Johor. Should be interesting, can't wait to see how the Johors mechanic managed to do that.

Yeah, when you are coming to Malaysia, to really experience the underground scene of illegal bike racer aka rempitsm, visit Kuala Lumpur on the Friday nights to Saturday nights. It's a chaos expecially at the usual hangout place like Dataran Merdeka. But the police patrol car are everywhere now...

Really? i had this impression that thais is the king of bike modification, be it cosmetic or performance mods.

Yeah, but a friend of mine was able to hit 185km/h on his 135LC. But, his bike was stripped to frame, cylinder bored to accomodate 65mm piston with high compression ratio using mixture of alcohol and nitro. After we do the shake down, we stripped the engine and guess what? the conrod twisted. To...

To do 190km/h on a moped bike would be suicide imho. And to achieve that kind of speed, serious modification would be needed. So i'm assuming that '190km/h' figure is more likely to be '160km/h' considering speedometer error. Care to share your bike setup?

May i have the catalogue plz, my email address is tq

'Knock knock' sound and damaged piston? The only reason i can think of is detonation. I assumed, your bike engine spec is factory stock. Would you mind to share, what kind of fuel are you using?

I've heard a rumors saying that the Malaysian version of 135LC, only the first batch are fast and has better quality while later batch using Taiwan parts and tune-down to meet JPJ requirement. Is it true? can anyone verify that claim? I do take this rumors seriously because this tune-down...

Would you mind to share, what is the stock front and rear sprocket on Malaysian 135LC? thanks.

Thanks dude for the spreadsheet. Now i get the basic idea on how tyre size, gear ratio, sprocket size and combination are effecting the bike speed.
