yes sir.. sir Chaz is right... you need to change your stock ecu to aftermarket racing(adjustable) ECU..

But if you want stock ECu.. here's the tip.

semi dome type piston 57 and 14/40 or stock sprocket combi the rest stock..

Im planning to buy after market ecu sir japs but i dont know what is the best ecu at this time coz plenty are good at this moment..any suggestion po??
Any update sa specs mo at this time sir japs??

 

[Kenshin18]

Sir japs can i add you on my fb account??

just to ask, is it advisable to use 4th gear alone in breaking up the speed of MC sniper 150? my new sniper is one month old, traveling long distance with 4th gear only with max. speed of 120kph. my 4th gear is freaking out! =)

 

[Kenshin18]

yes its freaking..why you dont use the fifth gear??thats why there is 1 more gear to speed up..

who among you here guys have used rc mini ecu for 177cc sniper? need your help
specs are:
option1 62cb forged piston flat
10 holes injector for 180cc
z5 cams 5.7 lift
open pipe
my question is what is your setting for this (on the ecu? ABCD) the number sequence.
currently our set is on 0911 good at top end with silencer but still has back fire.. not yet tried on open pipe
because of the crocs on the highway()
sir @JapSpeed need your master inputs on this..

Hi I'm new here just started my first project and i know is a little late to reply to this message but i had problems with my UMA RCM4 whichis the same aRacer mini c4,the thing is that your ECU has a default profile that is for stock engine 150cc (assuming you have a sniper 150)with stock exhaust,so because of this I bought the iLink cable and connected it to my laptop there they have different maps that you can get based on your mods,I don’t think there is an specific setting for any bike cause all have different things,I would flash one of those maps and start from scratch,is what i did with mine and is all good now,hope it helps someone...
That highlighted maps is what I would use if i were you,with the difference that is meant for a 160cc injector which is what i use on my 195cc and still was too rich before adjusting the ECU
(ABCD)
This ECU is amazing but only with the cable to get the maps.

Sir jap. Im from bacolod also. My current set up is spec v 57 semi dome, pitsbike ecu, uma coil, rest is stock. My concern is when i do rapid acceleration i can hear some knocking from my cylinder head but on normal ride wala nman. Is it normal for a semi dome piston? My current valve clearance is .6 and .8..ngayo ko advice pls.

Adjust valve clearance 10 & 15... Basi mabalian ka valve... Kung toktoktok sound delikado, kung tiktiktik ok lang...

Tikitik mn lng bro. Tapos kng idle rpm linong mn sya but kng arangkahon ko kalit mybati.an gd ko.

i think it's semi dome piston..

Sir jap mine is spec v semi dome and pitsbike ecu on my smx150. Which valve setting should i do on intake and exhaust? Im getting stuck on 9-10k rpm during high rev maybe valve float?

Check timing chain, tensioner & rocker arm...

Readjusted valve clearance to .6,.8. Looks like im having valve float sa 9-10k rpm bro. Do i need to change valvesprings as well?

Try racing valvespring like uma or other reliable brand... better use adjustable ecu...

sharing my latest set.
tuneboss ecu
cms t2 cams (5.8mm lift)
57mm dome type forged piston(spec v)
port n polish head

using 14x45 sprocket set(advance reading) rpm was very angry at all gears even at final drive, unfortunately speedo reading stays at 152kph but the rpm was very angry i guess i need to go back to the factory sprocket setting for more top end power.

I have on hand pitsbike valvespring bro. Okay mni ayhan?
