(this is for the puch estoril)
so just from looking around, ive seen brannano say they have a funnel shaped restrictor? where would that be located?
also hear they have a "ceiling" (maybe due to the long header?) which im pretty sure ive experienced.
ive been pondering cutting mine up to see if i cant squeez out some higher RPM's out of it.
because it seems like it tops out at relatively low RPM's
maybe taking some header out?
removing this mysterious restrictor?
ANY advice with modifying exhausts would be appreciated.
