if anyone has a reputable vendor that can mod or gas flow the head please share......the performance gains from that alone will outweigh the extra 25cc that a 150kit gives

guys!i feel like a complete LOOSER!!!want to know why??because my tuning problem wasn't caused by the carb!! it was my exhaust!!!thanks mike for bringing the exhaust thingy up!!
what i did was make it less restrictive...now it idles fine.... 
this means even if i used liquid oxygen for my bike it's still won't have idle well  .....will let u guys know if there's any gain or if it just a waste of petrol in a few days...
jayded1,
u mean to say that installing larger valves for intake ports will out do the 150 kit?? |

Glad you sussed it JB 
As regards the head, I would think the first things would be cleaning up intake and exhaust ports and matching then to the manifolds, possibly smoothing the gasflow at the valveseats as well. This is all professional stuff in my book though and certainly before having valve seats reworked for larger valves. I'd imagine any decent engine tuner could do the headwork ok.
Cheers, Mike |

OK. That's it!!!I give up!!
my carb doesn't pull well underload...apparently my carb that doesn't have an air mix adjuster,spells trouble. 
sure it can idle well...so what...
i feel like the carb gives my bike too much of everything...air and fuel...
so i've decided to scrap the project.....(sigh)
i guess it'd only work on 2 strokes...
But can't say anything about the one sold on the net though...because it's different..
next project

well at first my bike had the same idling problem too... so at last i found out it is the exhaust... so now i replace the whole system to Answer S11 system... Next month wanna 2 try the super trapp coz this answer exhaust is quite noisy.. and i found out 2nd thing, do u notice that when u pull ur handle to ur right while u idling then ur idle goes unstable...? Thats the throttle cable problem... i rearrange the cable but still sometime happen again... arrggghhh.... i just ignore the problem which is rev and go heheheh..

that's caused by your choke cable....i think you ran the cable on the wrong path...try adjusting to another path...that should help.
p/s:i'm using supertrapp...if you want quiet,this is definitely not it.  |

There's this other forum where someone mentions about a 170cc kit for the MZ125 from powroll,however the rumour is not true...i sent them an email here's what follows...
Hello Din,
We are not doing any additional parts for the MZ. The new owners of the MZ
corporation have decided not to pursue any performance products with us for
this engine.
Thanks,
