21t gigi gear yg ikat kat crankshaft ke?...xtau la...bagus ke tuka bende tu @ same je ngan std nye sbb bergantung ngan setting spocket gak...

kalo btol gear tu tuka yg kat crankshaft gigi gear blkg housing clutch xyah tuka ke bro?...

sory...baru nak blaja... Korek, Potong, Rebore, Port, Polish Blok & Potong Head V2 - Page 8 Icon_biggrin

x yh tuka.
hu3.
pakai gg gear 21 tuh ley la sumbat spocket kecik2 kt blakang.
disadvantage die mangkuk clutch cept bunyi.
tp brgantung gk ngn cara ko jokey moto.

Aku nak mod block angka bertukar 54.7mm (bore) 53.8mm (stroke).

Ade sape2 penah buat tak?

Aku tak nak rebore besar dgn stroke masih 54.7mm (standard) sbb aku nak maintain CC 125. Lebih sikit takpe.

& lagi kalau rebore besar nnt bnyk barang perlu tukar, minyak pun boleh tahan juga kan?? Minta pandangan otai2 sekalian..

Mcm ni bro..125z standard 53.8mm (bore) & 54.7mm (stroke) kan? Jadi aku nak modi angka bertukar aje dari 54.7mm utk bore & 53.8mm utk stroke.

Nilai stroke kalau dapat lebih pendek dari nilai bore lagi bagus die punye horsepower. Kalau ikutkan angka standard tu die lebih kepada torque & penggunaan minyak die pun tak berape bagus.

Tapi kalau aku modi dengan spec yg aku buat kat atas nilai CC die ttp sama. & kalau aku nak bore pun aku akan guna spec ni bro 56mm (bore) & 51.5mm (stroke). 126CC cuma lebih 1CC je.. Question

Nilai CC tak mau lebih dari tu nnt jd RXZ lah pulak. 125z tangki 5.5 litre aje bro lainlh kalau 13 litre & aku bukannya bawa racing pun. Aku rasa spec ni kalau long distance bolehlah tp tak tahulah mcm mana die jalan nnt.. cheers

Saje nak kongsi & utk buat eksperimen.. Very Happy

aik?nk tukar stroke jd 53.8mm?heheh...boleh,bro trim blok tu,jd pendek..hehehe,pastu rebore,saiz 1.00...lpas tu,kebabommmm...hahaha
aku rs xle r bro,mne leh pendekn stroke sk2 ati je..kalo nk pendekn,mgkin kne tukar rod len yg lebih pendek..
blok rxz ngn 125 beza stroke 0.7 je kalo xclap aku,tu pon dh kne tukar rod...
btol ke aku ckp ni? Korek, Potong, Rebore, Port, Polish Blok & Potong Head V2 - Page 8 452355 Korek, Potong, Rebore, Port, Polish Blok & Potong Head V2 - Page 8 452355 Korek, Potong, Rebore, Port, Polish Blok & Potong Head V2 - Page 8 452355

Tu lah nak tahu pandangan yg lain ni, mane tau ade yg dapat & penah buat..

Kalau stroke masih standard 54.7mm tp bore 56mm + 0.7mm, RXZ lah jawabnya. Barang 125z semuanya tukar RXZ. Mana boleh..!! hehe..

CC besar minyak pun boleh tahan juga. Tangki RXZ 13 litre bro..

Napelah engineer yang buat 125z ni tak ikut spt mana nak buat RXZ. Patutnya resultant, bore dibahagikan dengan stroke adalah sama dengan 1 keatas, baru ada speed (horsepower) mcm RXZ!!

Torque terlalu tinggi banyak benda boleh rosak.. bunyi longgar sana sini dalam enjin. Korek, Potong, Rebore, Port, Polish Blok & Potong Head V2 - Page 8 313242

cc besar xsmestinye kuat myk...tgk care gk...aku byk jmp rxz yg myk jimat,ada lg jimat dr 125z stended...
engineer dh blaja tingi2,mst ada sb dorg bt mcm tu,dh dpt master,phd dh kot...hehehehe...
semua part2 dh ada calculation,material,ketahanan,speed...
tp keje manusia,xda la sempurna mane...kn?

RXZ minyak memang jimat bro sbb enjin die lbh kpd horsepower oriented. 125z torque lebih sbb itu minyak kuat dari RXZ. Kalau nak jimat minyak nilai bore kena lbh besar dari nilai stroke utk mendapatkan horsepower (speed).

Sbb itulah aku nak cuba buat eksperimen ni.. nak tgk camana. hehe..

Moto 125z tp barang rxz termasuk carb, minyak die mcm mana bro?? tak sampai beberapa kilometer dh kong padan muka nnt tolak moto.. haha

Ko pakai moto standard kh bro?

hehehe...clap tu geng...motor 125z bleh lg jimat kalo pkai karb rxz...
skrg stended je,dlu pkai blok saiz enduro,dh port,karb rxz...myk lg jimat dr 125z stended..ngn rxz pon lg jimat...ngeh2...kne cr setting yg btol2 cun

Kalau 125z stendet mmnglh minyak tak jimat sbb torque die tinggi lah bro. Kalau torque tinggi minyak pun boleh tahan. RXZ torque tak tinggi tp horsepower tinggi minyak pun ekonomi.

cth pengiraan: stendet

125z: 53.8/54.7 = 0.98
RXZ: 56/54 = 1.03

Kalau lebih dari 1 makna nya horsepower oriented, tp kalau kurang dari 0.9 makna nya torque oriented.

Note:
Engines with long strokes have a lower compression ratio, poorer fuel economy, poor exhaust emissions, greater friction and have crankshafts that are subject to greater destructive forces.

Kalau 125z x stendet mst bore die besar kan? Agak2 besar sikit dari nilai stroke stendet 54.7mm. Carb pn kena tukar juga paling tdk pun adjust angin atau tukar pilot & mainjet. Ataupn RXZ lh jadi nya..Bore besar stroke stendet CC die besarlh bro.

cth: 0.7854 x (5.67 x 5.67) x 5.47 = 138cm3 = 0.138 litres = 138cc

Besar lagi..! TZMlh jawabnya..

Selagi resultant bore/stroke = 1 atau lebih, horsepower oriented mcm RXZ 56/54. Spt mana saya kata td kalau horsepower minyak OK tp kalau torque mmng parah.

Kalau motorcross/offroad aka naik bukit lebih oklah. Senang crt aku ambik cth kereta rally setting kompom torque tinggi sbb nak dptkn pick up & cornering.

Pasang injection belum pasti boleh jimat minyak. Kena ambik kira silinder enjin dulu bro, nak horsepower ke nak torque lebih. Nak laju boleh bro tp tak tahu ade ke tidak mereka2 yg penah cuba formula aku ni. Kalau ade feedback blh aku improve ckit. Tp CC die ttp sama cuma nak ekonomi minyak tu aje. Sbb itulah aku ambik spec 54.7 x 53.8 @ 56 x 51.5, janji CC die ttp sama. Jadi tak pyhlh nak tukar carb @ apa2 yg lain. Kalau tukar pn pilot, mainjet & adjust angin ckit & modi coil juga sbb horsepower die tinggi nnt short circuit pula sistem elektrik.. study study study

Tp kebanyakan moto 125cc kebawah mmng torque oriented. Kalau corner mmng layan. cheers cheers cheers

bro,xle nk bt mcm tu...kalo nk pendekn stroke,agak pyh,n akn mngangu lubng2 inlet n outlet dlm blok tu...1 lg,rod pon akn kkne tukar,sb blok dh kne trim,jd pendek...
n 1 lg,kalo xclap aku la,rmai bdk2 jek rod...bg stroke tingi...mgkn power lg bes,xpenah dgr lak yg downkn stroke utk dpatkn fuel saver...kalo dpt fuel saver pon,mgkin minyak kuat....tp kalo bro dpt squarekn bore x stroke,tu pon da ckup bes...mcm motor ss110..bore=stroke.
papepon,kalo experimen ni berjaya,aku tumpg gmbire...hehehe

Kalau pendekkan stroke, block pn kena selari jugalh bro. Potong dari belakang. inlet & outlet masih pada kedudukan yg betul.

Stroke tinggi, torque die jg tinggilh. Layan corner bolehlh tp sprint x leh lh bro. Jd horsepower kena tinggi.

Ni aku dpt info yg menarik utk rujukan. http://www.flamesonmytank.co.za/Articles/torque.htm study study study

potong dr blakang?dr head ke dr enjin?stroke pjg,torque tinggi,stroke pendek,high rev,tp torque low...
