yes bro, and still in PG12.
After playing 4 wheel for 3 years, really can't tahan traffic and miss my LC. But reviving it cost a bomb, 4.5k 

It's worth though, the fun is back.

yup. once modified, hard to turn back. It is poison.

Now I am still using old 15-37 sprocket, feel kind of short with new engine. Did some calculation to find the targeted top speed for each gear. here's a list, hope it helped others

UMA 62mm forged piston, UMA race cam, UMA valve spring, CMS head with 22/19 valve, custom PnP.
Remain 4 speed, as it is auto clutch version.

I see. Any brand for 65mm?

I choose UMA 62mm because it is very solid, heard quite a lot of reviews saying this forged piston is very durable, after 3 years usage still won't makan engine oil.

oh, shark. My friend said this piston will habis around 1 year, so didnt recommend to me. However, he is trying to gt 65mm UMA, and then jackrod 8mm --> 221cc

If he is successful, most likely I'd convert my engine with 8mm jackrod too, but using 62mm. That time will become 200LC liao 

It's ok to mix different grade of EO, as long as they are the same brand. I've tried for years, and the effect is good, if u get a good mix.

Challenge on 1km drag. So your bike can win 125z or not?

yea. ori is 5-speed, but can modify to 6-speed (i didnt mentioned it is a new modification, my bad). Bee Hock has 1 in his shop. but I pull till 4th gear 10krpm ady no balls to go further.
wah, 21hp. what's your setup, mind to share?

Finally the custom pipe is done. Power curve characteristic doesn't change much. Biggest change is overall torque increase. Low rpm sacrifice a lil torque for better smoothness, top rpm can pull longer. Midrange become even stronger.

Pulling up on ~5% slope, 0 - 133km/h (GPS) in 700m. LC standard meter should b around 175km/h

Added Firestorm after that. Engine becomes quieter and the midrange pull is even stronger.

stainless still 29mm.

This UMA is ady damn good base. Just need to increase the efficiency with better intake-exhaust setup. Will experiment with custom powerbomb when I have time.
Thanks for the sharing.

thanks for the input. maybe it doesnt work well for kapcai. I know Kelisa works damn well with it. Feel like increase another 100cc.
