| stroke tu pjg blok,dr kt head,smp kt enjin tu...kalo dh ptg,mst la jd pendek,con rod pon xsesuai la...nt piston kne head... aku blaja pon dr forum jgk..kalo slh,btolkn la | |

Head x payah kacau dulu takut compression die terlebih tinggi, bukan potong enjin tp kat block end. Stroke & block perlu diselarikan dengan betul supaya lubang intake kat block berada pada kedudukan yang tepat dengan muka piston.

ley la try nnty.ki3.. ptong blok. nk try tgk con rod ape ley pakai. mybe pakai rxz punye conrod kowt.ny da msuk budget overhaul da nieh. Bro aku dpt info Yamaha Enduro DT125 boleh pakai kat 125z. Bore x Stroke = 56mm x 50.7mm 56/50.7 = 1.10 0.7854 x (5.6 x 5.6) x 5.07 x 1 = 124cc Best ni boleh cuba, cun lagi tu..boleh kejar RXZ. hehe.. Minyak pn ok tak mencurah mcm air hujan. |

Slalunya aku dgr ramai yg modi spec die ikut size & pakai piston enduro tp stroke stendet. Tak pasti pulak block enduro ngam ke tak pakai kat 125z ni. Maklumat yg aku dpt tu kureng jelas.. Kalau nak stroke pendek kat 125z, spec enduro ni mmng ngam. Aku suka spec ni. CC die sama lagipun horsepower die lebih tinggi. Fuhh..kene cari bnyk info ni sblm modi.

| ubah stroke nnt timing api ke plug kene kasi ubah lg satu tukar rod pendek stroke xde ubah,yg ubah nye cuma jarak piston ke crank nak tukar stroke kene ubah jarak pin rod kat crank nape nak tukar rod pendek?tukar rod pendek kalu nnt volume campuran petrol kat crank dah jadi sikit..baik kasi potong permukaan atas blok @ potong head utk dapatkan compression lg tinggi | |

| hua3.btol gk.so solution die.sumbt piston besar dari ubh pnjang stroke.cc up ckit je.lg pown minyk x de la parak.rekod ak.pkai keihin pwl,piston enduro 0.0,bm power chamber cutting standard n reed valve carbon.ak isi penuh kt ipoh.kt tpah isi rm1.10.then sampai la ak kt shah alam dgn brbaki minyk 1/4 tank.setting n rekod trbaek ak prnh buat. | |

Lagipn piston akan tenggelam sedikit ke bawah. Utk mmperbetulkn kedudukan inlet, potong bawah block biar muka piston berada pd kedudukan yg betul dengan lubang semasa intake. Potong head tak boleh buat moto lajulh bro. Bikin piston pecah, rod bengkok & overheat adelh. Kalau nak buat moto "UP" (henjutan), compression tinggi tak cukup utk memainkan peranan. Enjin tak cukup stabil.. Volume campuran petrol a.k.a CC (displacement) pn kene betul jg sbb itulah bore pn kena besar bagi menampung keupayaan lejangan (stroking). cth perbezaan: 0.7854 x (5.6 x 5.6) x 5.07 x 1 = 124cm^3 = 124cc = 0.124litre tp kalau bore kecik?? 0.7854 x (53.8 x 53. x 50.7 x 1 = 115cm^3 = 115cc = 0.115litre Nmpk tak perbezaan??

mcm ko cakap piston tenggelam tu btol la kl rod pendek,tp jarak dr tdc ke bdc ttp sama,xde ubah
nak kira lejang = jarak dr tgh crank ke pin rod kat crank
@ jarak dr top dead center(TDC) ke bottom dead center(BDC)
TDC = kedudukan piston kat atas skali
BDC = kedudukan piston kat bwh skali
jadi walaupun ko guna rod yg pendek,jarak piston tu travel dr atas ke bwh(lejang) ttp sama,xde ubah..yg berubah cuma offset kedudukan piston tu jer,dah jadi rendah skit dr asal
kl dolo2 punya skema org buat 2 stroke,diorang akan cuba sedaya upaya utk tambah cc kat crank,ko plak nak kurang kan cc kat crank,pelik tu
p/s:tu rumus nak kira apa tu?nape pelik sgt?patut kl stroke 56mm,bore 56mm,cc = 137.93cc Maaflh bro jgn salah faham mungkin cara penerangan aku tu kurang jelas. Sbnrnye mcm ni, kalau dah conrod pendek, piston tenggelam jarak stroke jadi memanjang sbb itu kena potong block bwh. Sbnrnya penerangan aku itu berkaitan cuma tak tahu mcm mn nak menghuraikn dengan lebih kemas..hehe. jgn mare Yg aku xphm ni apasal CC ko kat crank. Crank @ crankshaft? Bukankh CC tu volume berkaitan bahagian pembakaran dalam enjin?? Formula pengiraan CC (displacement) = 0.7854 x (bore^2) x lejang x bilangan silinder. Nilai dlm cm^3. Aku guna spec kat enduro DT125 utk modi kat 125z.. Cantek budi bahasa..x pyhlh nak main ugut2..

| piston tenggelam stroke jadi panjang?camner tu?mmg le kl pki rod pendek(without adjusting the stroke point) bahagian bwh blok kene skim sbb piston dah turun..tp nape nak ssh kan diri pki rod pendek?xpasal2 duit dah habis utk bkk engine,skim bwh blok,set manifold ekzos etc etc..kecuali la kl pendekkan jarak pin rod(pendekkan stroke) kat crank,baru le kene skim bwh blok tu,rod plak rasanya bleh jer pki yg asal
aku rasa ko silap paham tinggi silinder blok = stroke kan?dear,thats only one way to calculate the stroke,but u have to understand that stroke = distance travel by piston,not the cylinder block high
okeh,yg saya tau dlm 2 stroke ada 3 isipadu kene amik kiri 1.isipadu silinder 2.isipadu head 3.isipadu crank-->this one determine the flow(volume from vacume suction),gas suction from carburetor to silinder
no 3 tu besenyer dah factory default(from r&d proses),xleh nak buat apa2 kecuali...hehehe
kl btol2 ddk kat jepun x kisah le..kasi perkenalkan diri dl kat forum yer
p/s:ambe ni budak baru bljr,otai kalu xde bising2 mcm ambe,otai sumer senyap jer baca ini thread lalalala~ | |
