excellent work - i'm impressed. can u show the BEFORE pics?
u widened and polished the carb opening? u didn't open the carb inlet right - that's still 5.5mm - correct?
i'm no expert but what does a wider throat do other than allow more AIR?
and even if u open the throat by 1-2mm that is only a VERY SLIGHT increase in the air volumn entering the cab. i fail to see any SIGNIFICANT improvement here... (but again i'm not very l33t)
now the crank - again excellent stuff - very sharp and polished work- u shaped the scoop up into the bore and it looks like u beveled the scoop back INTO the bore opening slightly.
how far can u push this technique - can u take it back FURTHER into the bore opening?
what about the INLET PORT of the crank? did u do any work back there? widen the port - flare the sides, etc? can u post a pic?
what about sleeve work - that seems to be where most ppl get creative....
(i wanna be l33t 2!)
