Im not sure if this question has been answered or not, but does tyre size 80/80-17 fit to LC135 front 1.6 rim? or the mudguard need to be altered as if the tyre will rub the mudguard? I have seen 80/90 fitted ngam2 almost hit the mudguard  and 70/80, but not sure about 80/80 & 90/80. I've seen also Y15 with 2.5 front tyre suit with 90/80-17 need to alter mudguard buat lubang.

And if i want to fit the 1.85 inch rcb sp522 on the front what size of tyre will be suited? and again need to alter mudguard ke? TQ

is that 65mm block?

76 x (58.7 + 8)
yours is like 303cc now right?

I wonder is this for drag or daily usage?

Berapa harga cam fz ye?

Apa beza high cam dgn low cam?

Woah tasty recepie. Head nak korek berapa mm? X pernah kacau head so x tahu

Gear box 6 speed R15.

Plan to upgrade :
Blok UMA 62 / 63 mm
TB standard / UMA 32 mm
Cam standard / UMA R1
Exhaust UMA cutting standard 28mm
Injector standard / UMA 160cc
ECU TuneBoss
Air filter K&N.

Con rod standard / need to change?
Valve spring standard / racing type?
Sprocket not sure for daily use

Which 1 is compatible?

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 ?

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.

mine using Keihin PE28 local, there's a gap between the air cleaner box like 3-4cm... during heavy rain, mesti kantoi semput2 then mati engine

can go for bike wash?

sedapnya vacuum pasir 

if u keep the box but remove the filter.. can feel difference?
