What problems are you facing regarding the intake?
Or what do you mean with 'best' or 'better'. It implies somehting is wrong or off with the one thats there now.

Well the current intake is meant for 32mm carb thats why it has the step. Im switching to a smaller 28mm carb and another rear facing intake and i want it to be as good as it can be. I dont know if the rich condition is caused by the carb angle, if it is i need a intake where the carb is as straight as possible |

Myself Id ditch the whole rear facing carb idea, a factor that could just ruin all the fun and everything. Id try to hang the carb somewhat in the same location as stock, but ideally with a less abrupt angle in the intake. Hebo/Barikit makes 24/28mm intakes which accept PWK carbs and have the carb in the stock location. Great if you don't want to fabricate one yourself. this guy used that particular intake along with a PWK carb   Otherwise buy a 90 degree weld-elbow and make one yourself. |

I dont really want to change the intake location because i paid good money for the intake and subframe

I bought a new yasuni silencer today, i installed it and took it for a test run, its almost double quieter than before. I dont know why but with the new silencer it doesnt run rich at all, works fine now. Broke 78.5 mph today

Wow your reed looks mostly intact wedged in there .
How does it get loose and fly off with out breaking off ?
The power you just putting out to go over 80 mph just sucked it loose .
82 mph is amazing that Cylinder set up really spins up with the C16.

Some of the high end racing teams had failures like yours with V-force reeds and those teams lost an important race..Might want to reconsider a 'snap in' reed retention system...  |

The reed cage broke in the area where it holds the reed in place  |
