Melaka Bikers - It's not what you ride, it's that YOU ride!

sorry for not replying....i am a little bit busy nowadays..many assignments and presentations to do.. :(well.i am not familiar with the sprocket settings,but what i knew is the rear sprocket size is 40..and i not sure with the front sprocket...i think my piston ring is not suitable to use anymore..although no smoke came out,but i think the starter felt very light because lack of compression due to the old piston ring..am i right? :-\is this will effect the pickup?from my experiences with honda c90,if we lack of compression in the burning chamber,the pickup will lost.....am i right?this is the picture of the head...https://www.facebook.com/photo.php?fbid=306946186050963&set=a.306946012717647.72367.10 please give me your opinions about this..i hope you can see the grooves and a little bit of crack on the head..what can i do?porting it?how much will it cost?and please add me in your facebook to!!

base on the explaination seem like ur piston already loose. Better rebore and replace one size piston... or change bigger piston 57mm
base on picture, seem maybe something abnormal ( valve or piston broke) .. in this case just polish by sand paper until the surface smooth.
i inticipate the front sprocket might be 15... instead std 14... because std kriss will use 14/42 and if the sprocket was drop only 2 teeth, it will not affect on the top gear (unless your weigh )

nice!! congratz MB'ians!!! tringin nk bntu,
ok gak plan racingzonne tu, pape pn bleh survey2 lgi lkasi, P.Dickson pn cntek gak.

ke PD pn ok gak.. bleh buat ride kesana.. tp kena fikirkn juga sbb AG1 ni buat mcm family day... ada cadang nk bwk family skali..
rasa ada baik buat dlm melaka.. huhu.. tp tngok dulu suara ramai mcm mana...

PD  teluk kemang? ada satu kat eagle ranch... siap ader paint ball
klu nak wat team building sesuai ar...

THANK YOU SO MUCH FOR YOUR CONCERN! :)from what i observe and feel,the motorcycle do not have any pickup at all..but i can tell you that my motorcycle has top speed..i can rev the third gear as long as i want.if i change to fourth gear,the speed went down..when i start the engine with kickstarter,i can eel that it is very easy to start it.what i mean is the starter feel very soft and loose..i think it is because low compression in the burning chamber.i want to swap the block with 57 mm shark racing block. i cannot post  the pic of my head here because the file size is too big.....in the head,there are many grooves on it..what can i do to smooth it up? ???what do you guys think?

em what is current sprocket setting?
seems like the ratio is low that's why your speed drop when u turn to top gear...

regarding to the head surface... just use a porting tip will do..
for the pic you can upload at FB and just put the link :d
for 57mm piston, better get the high cam for it's match then you will gain more top speed

okeh sambung lg... kasi bikin belah kiri moto..


kasi cat ape yang patut

Salam
Alamak td post kat english section da ter buat tajuk pun english da...
saje nak kongsi pengalaman n pupuk semangat DIY dikalangan Melaka Bikers
Hidup Melaka Bikers

Okeh....sejarah motot berplet moto JFK9327... motot ni asalnya kepunyaan seorang brader kat jb... pastu motot ni di wariskan kat adiknya... adiknya lanyak sampai jem pastu tinggalkan kat bawah rumah sampaila kene rembat ( ni tak pasti sebab klu kene rembat takkan siap geran + purchase agreement sekali
motot ni last bergerak atas jalan adalah pada taun 2003 n lepas jem dibiarkan tersadai dibawah ujan.. pastu rim belakang kene rembat ngan malaun mane tah.... last2 motot ni aku jumpa kat kedai besi buruk (haha ni favourite aku la... g jalan2 usyar kot2 ader barang yang best leh beli murah2) so ternampak moto ni terselit bawah timbunan besi2 buruk... so aku tanye la... sekali ader siap geran n purchase order... dapatla rm3 rat sian tul tgk keadaannya...



pastu kasi lerai semua... mau cat balik

hahaha :Dthanks for your opinions!i have done the top overhaul,i have serviced the carburetor,i have changed the one way starter bearing!all by myself(except for the bearing,dont know how to change it.)you,re right,the petrol has turned to jelly like liquid.i have cleaned it.the carburetor is fine,but still have 'semput-semput'.i cannot adjust the fuel screw,the screw is jammed already... :'(and i have noticed that the head surface is rough.this motorcycle is second hand ones.mybe the old owner scrapped the carbon on the head with screwdriver and drill.because the surface is not smooth,it's rough and has many 'lekuk' on it.the piston is not tight.the compression is low...so,i only can get 100 kmh this time..mybe some upgrades at the block,piston and head will solve it..what do you guys think?

for kriss 110, it top speed should be around 115-120km/h... (depends on the rider weigh)
maybe sprocket ratio to low?
regarding "semput2" maybe there is still some jelly in the jetting... you may change the jetting ( around rm3-6... depend on shop)..
for the dent/dint head, maybe last time something was happen... maybe any one of valve broke? depend on how deep is it.... i think better take a picture and paste here
for the compression, if there is burning mark on the piston wall/skirt, that's means the ring and piston worn out... need to rebore and change a bigger piston

In other word, the engine needs major overhaul!..is that correct, Art Racingzonne?

no, just servis the carburator + top overhaul ( block and head )
