Do you mean rust?
If on chrome part, can try Autosol. If on steel than you'll need to smoothen it with sandpaper and re-spray with high temp aerosol spray.

re-spray means i need to take out the exhaust first?

Leave it, the exhaust will last longer.
If you want to do it right, need to sandblast, treated with chemical, and apply heat resistant paint. That cost might as well consider a brand new pipe.

Recently heard the kuda sound Y15ZR in person.
To watch it on youtube is one thing, but to actually come face to face with one, is another.

I guess it appeals to different type of users, but I am not one of them.

Tomorrow, 27-28 October, Cubprix at Batu Kawan Penang.

i like lc135 v1 sound. more on the quiet side for me. can even hear the chain more than the exhaust sound if ride it casually. nice to sneak around

Just asking can I change my lc 5 speed clutch to the 4 speed no clutch ?

And does it give any problem to my bike if i do so ?

dont think so, sell the 5s buy 4s or swap one bike terus

assalam n good day to all pro/idola/bos/sifu.
sy nk mtk suggestion/advice. hopefully ade yg sudi menolong.☺
problm my tenggiling(y15) is my top speed blm memuaskan hati n need guide to improve the top speed.

FYI, my spec is:-

-c/block spec 65mm
-s/head 22/25 with porting sesedap rase tp blm bt CR
-camshaft t3
-tb kawahara 34mm with injector 180cc
-clucth standard tp (tukar spring racing)
-exhaust yy pang cut stad 32mm
-sproket size 14/35(before this use 15/35 but 5th gear rpm drop n try chge frnt srkt to 14, the result is my 5th gear can merayap but just can reach to 10k rpm. feel like no power to get more like others gear)
-ecu api
-rim sukan 125z(bunga lawang)

in my future plan is nk buat CR @ besarkan size monifold exh to 35/36. tp nk tanya pd pro/sifu, both of my plan which 1 should to do. or do the both? or any other suggestion/advice.?

TQ IN ADVANCE..☺

additional info:
- my current top speed is 150km/h(bike meter)@10k rpm/5th gear (diff with the other gears can reach to 13k rpm). 0-150km/h is very fast..
already try dyno but the result still same n ddn't get any sggst frm tuner. but dyno meter already reach at 195km/h( not sure for my meter coz just stand o/side from the room.

jack 4mm. balut crankshaft buat berat.

Hi all, nak tanya sikit abt LC V1

Previously bought:

• CMS block 62mm + forged piston
• M-Mate 19/22 head
• TLC camshaft 6.5mm/330°
• TLC Valve Spring 8L 48mm

Actually planning nak upgrade using the 62mm, then found out where I am right now, susah dpt suitable exhaust pipe and kalau pakai 62mm ni, the carb upgrade will cause the coverset tak dpt tutup habis. So i decided to upgrade pakai block FZ je (57mm) so that can just reuse the standard carb and maybe pakai exhaust pipe yoshi, R9, etc.

Nak mintak sikit advise for FZ block:

• should I use standard head or FZ head or better to use the 19/22 head that I have?
• use FZ camshaft or the TLC camshaft that I have?
• use FZ valve spring or the TLC valve spring?
• use FZ piston or change to a flat or dome piston? read somewhere that the FZ piston compression a bit low

The endgame for the upgrade is for slightly more power daily use, plug and play, easy setting, standard original carb so coverset dpt tutup semua rapi, and 150cc exhaust.

Thanks for reading, hope otai otai dpt recommend

All exhaust still have backpressure even without stopper or any parts that act as stopper. Even you use manifold it still have backpressure. Internal structure difference from one brand to another and usually internal parts does'nt have detail. The only option is low or high backpressure. Cutting standard always high backpressure and low backpressure is opbr, daeng, leo vince and others.

Good setup. 14-35 is your final tune?
Y15R with 62mm spec use 14-40 lower than 14-40 usually cannot achieve more than 10k rpm. 65mm spec might need to up your spocket size. 14-35 if you already change your gearbox ratio.

There is no problem with big carburetor. There is big space. Even Keihin FCR can be install and dont interfere coverset. My bike install UMA 32mm, UMA max flow air filter which the biggest air filter and I even install oil cooler at the airbox placement. Still does'nt interfere with my coverset. What suitable pipe did you expect? Silent and perfomance use cutting standard expect UMA exhaust. You need to find suitable tuner. Tuner will tune according to the spec.

Fz performance is same like standard. You improve this and that still side by side with standard one. I already experience it, on convoy, saturday night and going to work.

bila pomen cerita harga bearing C1, C3 etc i was like

Using PE28 / PE30 carb, the centre coverset can close properly? From pictures that I've seen, the centre coverset mostly open and the carb can be seen jutting out. I might be mistaken though.

I'm ok with loud pipes, just that where I am, most of the racing pipe are rated for 150cc max.

As for tuner, I assume you talking about the mech? I can't find or haven't found any suitable mech here

My LC135 sprocket ratio now is default;15 39. May i know if i change to 15 38/37 will improve my top speed and make long riding more comfortable?
I usually will go 100/110 kmh

my lc currently using PE28 + uma max flow air filter, no problem at all

in the periodic maintenance table, item no. 3, what does it means? is it the top overhaul service? anyone knows when do we need to do top overhaul service?

get GPS speed first, dont look at meter motor.

before anything, try cheapest option first, up rear sprocket to 36,37. pepah dulu seround dua tengok gear 5 boleh naik 11-12k rpm orait dah tuu. or maybe tukar cam yang ngam dengan machine tu. my bike spec 63 std modi, head 19/22 sprocket 14-37. berat 80kg

Boleh sumbat masuk eh? Cause someone I know using PE28 carb, cannot close the centre coverset

check valve clearance means just open and check the valve clearance using feeler gauge

Anyway, I'm not so sure if my regular mech know how to tune carb properly for 62mm. Takut nanti dah beli carb and pasang everything, he cannot tune properly, lagi banyak masalah.

So I figured might as well plug and play with FZ block je
