Korek, Potong, Rebore, Port, Polish Blok & Potong Head V3

kalo nak port lubang angin ngan minyak,
adakah perlu mengikut ukuran?
atau bleh port sesedap rase nye,
egt nk wat sendiri, brg da ad, tinggal nk wat jew HEHEHE

tp nk taw ukuran nye cmne dulu, mintk tunjuk ajr
port lubang angin,minyak ngan ekzos

nk tiru spect aku kasi rebore blok ko tu g saiz 1.00 terus...baru sama dgn spect aku...
tp aku tau ko xkn wat sbb ko bijak orgnya...heheh

Wakaka... man, ble2 bley DIY blok aku...
servis buang karbon jer dah ler...
hehe....

ezad: amboi2.. byk mase lapang btol mmbr br lepas spm neh yek..? wakakakaka.. bleh wat sendr, tp kalo 1st time yg sgt2 1st time elok la ade org brpengalaman bg bimbingan skali.. ceit, mcm skema je ayat aku..? haha.. tp tu la die, mende salah port performance mungkin tk dpt mcm yg diharapkan, overport plak susah/tk bleh dpt setting ngam, terus buang je blok tu nnt.

yap: yg mane satu nk diportnye bro? kasi experimen yg bukan orimoto la.. piston pn besar.. kne plak ko 'tiru' spec manjaNGAN, lg mencanak2 pegi.. piston 1.00 rxz tu.. pergh.. wheelie tk trun2 bhai!!

ape nie??? aku sikit pown x paham nie... saiz piston rxz????
Jom... marilah DIY block aku.....

maksudnya cari blok ln wat port..watla byk mana pun nk wat smpi nipis sleeve tu pun
blok 0.0 tu kasi simpan...
senang papehal kemudian hari...
bkn senang nak cari blok 0.25 standard ke bwh skg ni...

ouh, oke2. bro berpengalaman x? HAHA egt nk try pinjam )

nk pinjam ape ezad...blok ultra tu ke...huuu...mcm harapan je...
aku dpt tgok lobang ekzos dia tu pun just bila dia nk diy je..diy pun bila head dia leaking..piston berkematu & etc....
kalu xharapan la nk bkk tgok lobang ekzos dia tu...heee

ouh, bukan pinjam blok, tp pinjam encik ultra untuk melakukan kerja2 seperti berikut

manjaNGAN: wahahaha.. rahsia kejuruteraan bro.. gua melabur beriban ratus mane leh bg free2 je. wakakakaka.. padahal kalo aku nk copy tegak2 spec blok skg pn tk mmpu lg dpt 100% rasenye..

ezad: alamak.. nk pnjam aku ek? aku bukan reti nk pegang drill utk porting tu. benda nk kne ari2 main + try n error bbrape belas blok yg naseb mungkin jadi, mungkin bakal dbuang ke parit. sbb tu pomen yg complete alatan n pengalaman je brani nk porting blok neh dgn perasaan kompiden..

kalo da modi,blh jimat kn minyak sket x??kalo tuka jarum rider ngn pantel gamma mane lg cun??

kalo modi minyak akan kuat dr std...ikut tahap modi gak...

contoh kalo wat porting...kalo kite da porting lobang angin, kite kne set balik minyak utk bg mixture minyak n angin sekata balik...lobang exzos lak utk kasi up lg RPM, so bile da hi rpm kne la lbeykan minyak ckit br bley support...

slalu org pakai jarum panther kat carb RXZ...

sbb aku pnye blok br saiz 0.25,,ulang alik g kls mnyk koyak r,rm10 utk 3hr,,mcm bwk kreta plak,,,bwk slow lg koyak,,igt nk jimat kn minyak sket,,erm tgk moto membr aku jarum die pnjng sket,,myk save,bwk laju pon kaw jgk pegi nye,,ade komen x?

no komen...haha...

xkesah nak set carb mcm mne pun...yg penting mixture minyak cun...plug kalo color perang gelap ckit tu kire da ok la...lps da set carb br bley tau minyak kuat @ x...

minyak slalu kuat kalo moto kuat membobok...lg2 pakai carb 125Z...masuk RXZ nye carb bley kurangkan bobok n low rpm jd ringan...tu pengalaman aku la...mcm carb TZM@TM@PWK xpenah try lg...

stended pun bg ak dh kuat...ni kan plak yg dh modi...



ni ak nk tnye ni.....
kalaw moto dyg dh potong head...akn cpat panas kan..
so..kalaw bwat jalan jauh....boleh ke maintain cara ride moto stended...
mksud ak bwk mcm biasa...140-150 n bheni2 mcm oto stemded..
ataw perlu urgkn klajuan...n lbih byk bhnti

bleh je kasi naikkan takuk kt jarum tu. mksudnye jarum tu jd lg ke bawah.. maybe ade risiko jam jugak, tp mmg kadar penggunaan petrol lg kurang..

moto aku blok modi + head potong 3mm + *, blk ujung minggu batu pahat-kota damansara dgn kelajuan lbey kurang spt yg di'bold'kn.. er, meter keta ye.. bukan 125z..

*pnjg plak kalo nk cte spec keseluruhan + (blok calar segaris akibat seramik dlm plug pecah + head berlekuk2)<-----ade gmbr kt myride..

ak nak tnya erk..
market harga blok racing 125z brapa yer??
taiwan made pnya...

mksud bro xde problem la even bwk laju?
ak risaw jln jauh ni...xpenah lg jem sorg2 atas highway...hahah

sbb tu la modi neh kalo bleh berperingkat..
leh bace mesin tu.
kt mane nk full throttle, half throttle, 'pancing rpm'.
tiap kali nk power; drop gear, perah kaw2 kemampuan enjin mmg cpt jahanam la mesin..
n bukan aku full throttle spnjg jln, ble rase enjin ade berat sket aku slow down la sket rpm kt 5-6k ke, ble rase nk pepah blk tarik je la smpai rase tkleh gi dh.
n kaw2 tu bukan kaw2 all the way jugak.
maintain kt rpm 8-8.5 je, ade time smpai 9k, pastu maintain blk kt 8-8.5k..
telinga kne sentiasa peka.
dgr je knocking siap sedia tarik clutch.

bleh terangkn x bro ttg knocking tu?
knocking ni dsebabkn modi headkn?
ape efeknye?

abg_apis: eh tkdela kaw2du smpai 240 meter 125z.. dh tkde nombor/takuk dh kt ctu. moto spec standard modi je, ekjos pn standard carbon dh tepu.. 170kmh meter 125z 2nd model, rpm +8.5k, beh kuang 140kmh meter keta..

babet: bace neh; engine knocking
knocking bleh jd berpunca dr 'minyak trbakar awal'.. phm2kan la ye ape die ckp..
dipetik dr link td tu:

Quote :

Causes of pre-ignition include the following:
- Carbon deposits form a heat barrier and can be a contributing factor to preignition. Other causes include: An overheated spark plug (too hot a heat range for the application). Glowing carbon deposits on a hot exhaust valve (which may mean the valve is running too hot because of poor seating, a weak valve spring or insufficient valve lash).
- A sharp edge in the combustion chamber or on top of a piston (rounding sharp edges with a grinder can eliminate this cause).<---bucu2 tajam kt combustion chamber/piston(maybe berkaitan porting blok/head atau kt sistem 4stroke aje)
- Sharp edges on valves that were reground improperly (not enough margin left on the edges).
- A lean fuel mixture.<---minyak kurang
- Low coolant level, slipping fan clutch, inoperative electric cooling fan or other cooling system problem that causes the engine to run hotter than normal.<---blok/enjin pns melampaui suhu operasi ideal
- Auto-ignition of engine oil droplets.

head tk modi pn leh jd knocking.. lg2 ble rpm dh lbey dr kbiasaan enjin standard(kt 8k je kot..?).. kt rpm tinggi neh dh tentu suhu n tekanan lg tinggi. tp ble head modi(skim contohnye), compression jd lg tinggi, n kt high rpm lg kaw2 la suhu n tekanan.. psl head modi, gi cari blk info psl skim, modi kawah, squish band, squish chamber..

encik ultra dan sesape yg berpengalaman...

motot tua sye nih igt nk gak porting cket....tapi dah bace dari V1 sampai v3 ni..
masih lagi kurang kefamahan dari sudut porting tu sendri..

tgk dari gmbar2 sume nye berpiston besar n lobang angin + minyak + ekzos di port kaw2,,,

kalo takat nk dpt kn rpm lebih dari 8k(skrg gear 6 bole tarik smpai 8k je)..dengan blok dah di rebore 0.5 ni...ade x formula yg sesuai tuk blok tu bro?? wat mse ni head da skimmed 1mm,pilot 20 menjet 120,kotak angin buang air filrter tebuk lubang byk2...spoket 15/38..

sye igt nak up lg sket performance moto tua ni...tolong2..

eemmm... cm biase nye ntar bengkel yg wt.. sbb ad ukuran die.. x bleh sesuka hati korek... mcm blok aq lubng angin + mnyak skit je usik.. skali imbas mcm x usik... cume lubang ekzos n dinding je yg bnyak wt.. lain pomen lain skill... sblum port rpm mati 7.. pling kuat pon 7.5.. lpas port n condisi mtor tip top rpm 10.5.. spoket 15-35..

spe2 ad pngalaman psal resleve story skit baik buruk...
