haha, slowly find a pomen tat can do the stuff i recommended u in PM. If they said cannot, I am sure they have no skill and no knowledge on 4-stroke engine.
If you dont believe, buy a book called "4-stroke performance tuning" by Abraham, I am just summarizing and share those knowledge with you.
Airflow is the most important, followed by fuel supply. CDI can change later.
That's the problem..and the reason why im still asking for help here..Nowadays hard to find good ppl/pomen that soft spoken and try to give a reasonable input for learner/customer. Love to read but Sorry i've like no more time reading..usually went home already tired and sleepy..
Discussion, Practical and have a looks over it much better for me

yes, u r right aaron. Stock CDI ignition timing is meant for restricted air intake and exhaust system. It is cater for standard setting (including the PJ and MJ setting on the std carb). Changing to after market CDi helps very little only.
But once we increase the airflow into and out of engine, the whole engine characteristic will change, and we need a more aggressive spark timing to keep it up. That's how aftermarket CDI helps. And remember to buy adjustable CDI, fixed one are useless, bcoz every new airflow and carb setting will need to retune the ignition timing for maximum power gain.
Added on July 27, 2010, 1:24 pmyea, that's the 'bible' for engine modification enthusiast. If any pomen dunno these, his knowledge is very limited -- he doesnt even know the basic theory
hehe, for racing block, we really really need to be sensitive to a slight change in engine condition before the problem is worsen. Maintenance fee is $$$, and highly recommended to use good fully synthetic oil.
So BRT DualBand is not adjustable? Looks like changing to a custom block really high Risk eh? U using 1 too right?
If u have time going back Home in PJ, Have a look on my bike lorr and bring me some good place to tame it..We can go YamCha² after that

Changing exhaust will increase the overall airflow in the engine itself, thats why need to reset carb if necessary. Oh well, if we want more power, we must play air-fuel setting. Where to set the air-fuel??? Carburetor. Changing exhaust without taking out the air filter is like... you kentut a lot but never breath --> sometimes power feels awkward.
My recommendation is remove air filter (guaranteed minimal harm to engine), change exhaust pipe with white fibre and reset the carburetor. Only when you have good amount of air-fuel mixture present in the engine, then only 1), 2) and 3) has the highest efficiency..
imagine... if you cooking tat time, js open very very little gas. How big the spark u put also the fire small only... That's why many who do only electrical modification gain minimal power... on top of that, electrical device cost a lot. Not worth at all.
If want Kentut a lot but no breath, where got powerful Kentut maa hehe
I'll consider to grab ur Custom pipe Charge but is that ok to change the stock Block along? Stuck without dunno who to refer for easy talking and know to done those adjustment..

haiya, how kotor also dust only. If the EO is good, those kotor dust will be trapped in the oil la. engine sure wont kena one, the piston and block is tough. u rub the sand against metal, which one u think will die 1st? lol
for me, I do regular carb and engine servicing, so air filter-less is nothing. everytime engine take out also looks 10x cleaner than those who got air filter but never service before
Normally Carb and Engine Servicing will cost u how much dude? Any time frame to do that? Give a tips plz hehe.. Nearly hit 11k Mileage soon, shud i do that?
I believe the durability of block u're mentioning here is for stock right? changing custom block still playing in my mind following pipe, plug and CDI if necessary (Carb? dunno lol
). Wanna feel Smooth and Steady when Cruising sometime on those Highway like Duta, Penchala Link and Federal..Normally riding around 10KM ~ 20KM in weekdays huhu
