yea it looks like the one used by the blogger, he writes some interesting stuffs as well, thx for sharing.

I have installed the filter last night. Gone the carb. 'ceh ceh ceh' noise and this morning on the way to my workplace, everything works well until around 7.5k rpm (110km/h) my bike is like suffocating. previously, I could revving up to 12k rpm (not yet full throttle) without problem... also the exhaust fume is stronger. yup my carb. is now rich and i feel too rempit will try tuning the carb. later, if it doesn't work, only then I'll send it to shop.

For me it depends on your reason, if its purely for speed than I would just upgrade the LC4s.
If its because you want a new bike with new tech, than buy a Y15.


I'm using CJ Ipoh but older version than the one on the video. Can confirm with fiber it sounds 'padat', I don't know how to explain the sound in English


Pening UMA ni tak bagi saiz manifold ekzos dia. Sekarang ni pula dah ada 2 versi ekzos dia. Satu yang lambang warna ungu, satu lambang warna putih. Tak pasti mana yang model lama, mana yang model baru.
Tengok dari diagram dia bagi, internal ekzos baru tak sama dah dengan yang lama. Macam ada nenas (aku tak tahu nama betul apa, ini istilah geng kereta ) dalam tu.


Yeah your bike sounds rich, to confirm you should check you spark plug for black soot.
I would suggest lowering your main jet 1 step.

right now im not using air filter.

i should install one, right?

That type of carb filter has these characteristics and effect:
- make carb runner length longer, top end gone. Effectively, it doubled your intake manifold length, so low end may gain just a bit. At high RPM, your bike is suffocated.
- small plenum area, AF-ratio becomes rich all the time.
- hard end cover at the top of filter, multiple resonance effect making bike loss power at different RPM range.

Compared to stock airbox with the following characters:
- shorter runner length, better mid to high end.
- bigger plenum, less likely to suffocate.
- better noise suppression, less likely to have resonance effect.

I have seen in YouTube on how to change main jet for my carb., I don't think I can do that by myself... too complicated, I am a newbie je

do you mean the air filter is no good? it's only RM11.90 can you suggest any good air filter? I ride passes through EKVE and SUKE highway construction everyday and even worst recent weather always raining heavily

can Apido 180 50mm serves the purpose? or I just go for Uma max flow 50mm?

hi guys. i feel like something's wrong with my lc135 2018. starting my motorcycle with electric starter need many tries.. and i feel like my motor is getting underpowered. mileage 2.8k.

those measurement of these filter, which part of the filter or carb it is referring to?

eg the uma, 50 55mm is size of ?? for carb 24-28mm is which part of carb 24-28mm?

Yes, you should because your carburetor without air filter is not easy to maintain. It need to clean and tune back when the idle start not stable. Better use UMA Max Flow type because cone air filter which is UMA Power Filter type air flow is to restricted.

Hi,
Check your choke lever or change your plug.

Hi,

Does anyone have recomendations for LC135 V2 modification to reduce fuel consumptions ? My current bike is totally standard right now. I am not going for very high speed, just to drastically reduce fuel consumptions.

I am not sure what it's called but it's the part where air-suction taken place and it's attached to air filter system, air intake maybe? in my case, Keihin PE28, it's the B diameter which is 50mm. while the filter in the ads refer to the inner diameter of the filter.

I have ordered the UMA sport max flow 50mm and while waiting for it to arrived, I have removed the cone air filter and only using its 'neck'/ 50mm rubber hose to connect back to the air cleaner box. gone the suffocation problem during 7.5k rpm

your full tank now can go for how many km?
mine for average RM6.00 / RM2.20 per liter RON 95 which is 2.72l can still serves me for 115km. previously while still standard, I can go about 140kmh average. got few times about 160km if I rode 80-90km/h only.

From my daily ride to work, I managed to go 108.8 KM, before the fuel gauge hits exactly at the red area. From what i understand, in the red zone you can still go around 20-30KM right ? So, I would say pretty close to 130KM for full tank.

thx for the infos,

how much is the filter? saw online is like rm120 ??

your fuel consumption looks normal, i saw a post recently at FB selling fuel injection set for lc135 but not much info about it and i am not sure whether it's really worth to replace the carb. sys.

most are selling with that price, RM120 but iinm there 2-3 sellers at shopee selling at RM88. i bought it from shopee at RM75.41.

merch. subtotal	RM88.00
ship. - pos laju	RM5.04
ship. disc. subtotal	-RM5.04
promo code app. (maxis)	-RM10.00
redeemed 259 shopee coins	-RM2.59
order total	RM75.41

during 10/10/2018, got RM15 voucher with min. spend of RM80 but for only those early, the price might go RM88 - RM15 - (free ship. coupon) = RM73.

Just sent my lc 4s to workshop convert to fuel injection,hopefully can get by this week to test out

Wow! Are u using the fuel gain kit injection set? Interested to know as well how is the result of the conversion to fuel injection, especially in term of bike performance & fuel consumption rate... I'm a bit disappointed with the fact that Hong leong yamaha simply never upgrade lc135 to fuel injection...

Baru tukar yypang cutting standart. Rasa menyesal pulak, bunyi angin carb, bunyi ekzos, bising betul. Tp nk buat mcm mna, pakai kotak angin nnti angin tk support, pakai ekzos standart nnti asap tk lawas. Adoi, tk boleh jd silent killer

Pakai uma max flow ni angin boleh support ke kalau spec 62?
