Wei u still in China?

My clutch plate RM85 is original yamaha for lc135.. i dont use other bike clutch plate for my bike bcoz idk they got any other side effect or not.

Yar la business ma bro. They think short term only... About brand i wont let the foreman decide i rather go get the stuff and ask them fix for me.

Maybe can try this shop TLC

Address: 16 jln taming kiri 2,tmn taming jaya,

Lastime i also think more bigger valve is better but after the foreman explain to me. Bigger is no use if u play drag. If want put bigger valve must calculate too. Bigger valve will not have much power if the bike cc is low. So mean more bigger valve need higher cc if not the bike will tengelam when shifting gear time.. Bcoz lubang besar but power tak cukup..

If want the bike fast is simple only invest on a strong block 60mm onwards. Carburetor, hi cam, pipe, CDI. If want play head your bike must at least 200cc onwards only can think to use big head valves. If not the bike will only have top speed and no power. Which only good in highway. Not on the road.

Cannot one. if u want follow cubprix spec your bike tottaly cannot ride for everyday use. Those cubprix bike not using normal pistons. they using dome pistons. Compression very high. Pick up very good. if u pull your throttle hard on highway. Than u will findout that your engine have so many leaking problem. They set they bike for track use only. The bike also cannot use starter d. If u can tahan tukar pistons, valve and block every month maybe still can think of it.

If really can do like cubprix spec early early many ppl will do alrd no need to using big block d... 4stroke not like 2stroke.. if 2 stroke even a standard pistons porting the block nicely the power alrd increase so much d.. If want do like cubprix spec only can do on 2 stroke bike. Is wasting money to do on 4 stroke bike. Bcoz need to sacrifice alot to get that kinda power.

Normal pistons wont get 22hp d. If really want modify like cubprix better get a 125Z. No need change big pistons one. Porting, change carburetor, Put chamber pipe. Enough for you to kill TZM liao

Sometime we see ppl ride slow ma also mati juga..

The secret is on they piston and the ring.. You see the bike really must warm up before race bcoz they bore the block slightly longgar abit so when bike really warm up piston will kembang until fit nicely on the bore. Not too tight and not too longgar.

They engine run at high RPM + very hot all the time so for them np. And they change block and piston every 2 or 3 race. But street bike will be problem abit bcoz we dont everyday lap. If piston longgar got bunyi one.. And will damage the block.

Cub prix have rule and regulations. If u join 115cc category. You cannot make your bike more than that cc. No care you use what bike also. And they gearbox have spec also. Cannot simply change the final gear, only aloud to change whole set of gearbox. And the tyre must minimum have 70 - 80% bunga if not u have to change tyre. And all they fuel is RON95 from petronas. Main sponsored.

four stroke bike very expensive they spend estimated rm100k per year for a single bike. They all race to promote they brand. they got earn one. But if we the privater want to join than we will be burning money alot. Because no ppl will want to sponsored you until you can prove that you have skill.

Yar laa that why so much mat rempit bcoz no place for them to race legally at a lower cost.

If they got skill than ppl ambil la if no skill how? Rempit laa... If not what else?

Actually a jockey salary every month basic they take like RM1500++ depend on how good they are. And if u win a race they give u 4k for each race. If you are a overall winner at the end of the race they give u 15k. This cubprix rider alot depend on side income. From the sponsor. Why i know this because i got a fren is a full time jockey in cubprix. But alrd retired because of the age. He use to race in 115cc amateur category. But now he cant race anymore bcoz he over the age limit.

Im talking bout amateur 115cc category. Not sure bout other category. And definitely kuda jockey earn more than cubprix jockey..

Change bigger bike.
