sorry it isn't really GPR/RS, but it has D50B0 engine (bike is Aprilia RX 50 2016, more or less 'rebranded' Derbi Senda DRD R). Current setup is like this...
- engine D50b0 with stock 50cc cylinder,
- pipe Turbo Kit RQ

- stock carb PHVA 17,5 (upjeted with removed baffle plate)
- stock air filter
- front sprockets 11 to 13...
I have few questions, since this pipe is quite hi revving, up to 12.000...
- should stock crank be ok (that's at least my concern, just checkin)?
- Are stock reeds ok? I've got mixed opinions on this, some say they are fine, some that they should only be changed with BBK, some say that they only good on completely stock bike?
- Stock CDI Ignition isn't limited, I guess it's safe to 12.000 rpm?
I should add that I never trash it over 10.000 for longer periods...
Thanks...
