@ Sonnyjha - anu gamit mong sprocket combi paps?? TIA

16front 38rear.. pang dulo pinili ko kasi ndi nman na iniinda ng engine ung arangkada pag kargado na makina mo..ndi kona msyado ramdam ung lag ng arangkada..

what is the highest speed that you already have attained with that sprocket combination bro?

 

[Sonnyjha]

pakiramdam ko half palang ng 3rd gear yung 120kph tumataas pa ksi kaso wla na kalsada..

1st gear -65
2nd gear - 100
3rd gear - 120 tumataas pa..
4th gear - wla na kalsada..sa mindanao cguro masarap magtest dun sa road nila sir traxx..

kaya naghahanap me ng 21teet ng 4thgear mas mabilis sna maatain ung final gear if mpapalitan yung part nayun..

 

[Rolly]

have you tried sprocket combinations 16/42 or 15/42 (F/R)? try mo bro para magamit mo 4th gear...

 

[Sonnyjha]

natry kona dre mag laki ng sproket sa huli kapos sa dulo..mabilis umiyak ung engine talo ka sa r150 at CBR150 sa duluhan pag gnun..

 

[thopiang]

kung loaded engine nyo, try 15/38 or 15/37, kahit 250cc pa yan kaya hahahaha

yeah tama kadun master.. kaso nkakalungkot minsan pag naramdaman mong wla ng ibang motor na mkaabot syo..parang nagiging loner ka nlng mag isa sa buhay..pero kahit na kargado na motor natin ndi ko maramdaman na malakas sya sa gas.. racing carb nlng dkopa pinapalitan sa engine ko chaka bigvalve..

eto: also try to usse 30mm carb and a big elbow with big mouth pipe, it will sound like a crazy 450cc, run like hell and consume gas like you have your own gas station hahahaha

yikes... ok lang sana to if kasing laki rin ng 450cc ung gas tank natin..eh kaso 4liter lang san mkakarating yun?balikan lang yun snpedro alabang malamang..

 

[Rolly]

i am currently using Keihin PE 28mm. performance is better than the stock carb and fuel efficiency is even better than stock. i can have 35-40 km/liter depending on my driving mode.

during one of our rides, i even consumed lesser gas than one rider using a stock bike...

what are the standard sizes of the main jet and pilot jet of a 30mm carb bro?

 

[Sonnyjha]

ahmm...ano po ba tlaga ang totoo? nkakatipid ng gas or nkakalakas ng gas ang carb? medyo OT na ata tayo mga bro...whehe!

 

[rr117-sacker41]

ahmm...ano po ba tlaga ang totoo? nkakatipid ng gas or nkakalakas ng gas ang carb? medyo OT na ata tayo mga bro...whehe!

depende po yan sa settings ng mj at pj
paglaki ng mj paglakas ng konsumo ng gasolina......d b mga master?

 

[Sonnyjha]

ahh so meaning kahit stock pede rin lumaklak ng gas pag sinagad ung settings ng MJ.. yan nlng tlaga kulang s MC ko chaka bigvalve..

i used wabron 30mm carb with accelarator pump (same as stock) - 45 PJ and 105MJ

buo pa po ba yung liquid cooling nya mga naka 61mm? I mean same as stock pa rin yung cooling jacket nya? Thanks!

 

[Rolly]

yes. there are no modifications needed when it comes to the cooling system. the volume of the cooling jacket may be a little smaller than stock due to the larger diameter of the cylinder. so far i have not experienced any overheating yet.

 

[sprinter]

hi guys...is it ok if i rebore the original stock cylinder block from 54mm to 60mm?

will it withstand the preassure and does not cause decreasing volume of engine oil or other effects?

 

[Rolly]

AFAIK the Diasil Cylinder cannot be rebored and even if you were able to rebore the cylinder, it would become too thin and might cause problems such as mixing of coolant and engine oil. IMHO you would be better off buying a new big bore cylinder block...

 

[sniping_area]

it can never be rebore but can be re sleeve using pin 15 piston set...

comparing 61mm to a stock bore...

 

[technician]

pafs something wrong with the installation pag nagleleak... wala sa bore ung problem.
