i think your mj is too small current jettings are good for stock bore... so you need more mj on it... IMO

Thank you very much boss Japspeed, a how about the gas consumption sir? if i change to bigger mj? and a/f mixture sir if you have any idea?
change your mainjet to 115 sir.. nakakatakot yang mainjet mo... mabuti pang mag over feed ka kesa under feed.. masisira engine mo nyan//.

just to share my experience about main jet.. depende rin pala to sa ginagamit nating cam.. sa tuned 57block ko with stage 1 cam kaya 110 to 115 na main jet.. but this time i am using stage 2 cam. bitin ako sa 115.. at bitin ng kunte sa 120mj pero okay parin naman ang takbo...
laki ng pj paps..

Good pm Sir Ojie just wanted to ask if you use uma racing cdi too? and about the spark plug did you use the original spark plug before you use ngk G-Power plug? because at this moment I am problematic cause of wet fouling of my spark plug resulting in hard starting, am using 62mm bore too but not uma, swrflatslide 28mm 37pj 110mj still not changing the mj as the other concern member adviced me to change into bigger mj but for now my gas consumption and spark plug analysis resulting in rich condition. I already ask my mechanic to tune my carb but i still have the problem. please advice and i hope some other new member get usefull information in my post here Godspeed Ridesafe to all.

Nope sir, im using brt powermax dualband directly bought at Bandung (indonesia) as in singapore theres alot of this fake brt cdi. Plus i also change my coil to yamaha yz 4ss ignition coil with ngk g-power spark plug . my mj is slightly bigger 120 because i like to rev all the time so i played safe. My plug burn so far was tan color which is gd. Ohh and btw i jz tune my carb with 1 1/2 of air screw. I just change my racing cam to rextor.r cuz hv higher stroke 6.2 if im not wrong. Hope this help.. For pwk28 carb i hvnt tried yet. Its so ex in here.. Lol !

Don't use normal stock spark plug as i was advice by the mechanic (brt) at Bandung that "if u using big bore block and ported or polish head & also open exhaust (aftermarket) its best to use ngk g-power and run a little rich in ur settings." I personally tried using ngk r plug but g-power still the best plug for me. For imc uma cdi, i hvnt tried it cuz for me its troublesome cdi which u need to find the mapping. Plug & play is better. Dualband powermax was recommended to me.
good day sir,
hows the performance of ur SWR 28mm?currently im using this carb 110/30 still in stock set up but im planning to upgrade into super stock (PnP head,rcdi,cams stage2,Vspring).any recommendations on jet sizes?and fuel consumption.as of now medyo matakaw sa gas. .
*still in stock pipe.
thanks sir,ride safe
