try adjust floats. maybe not enough gas in carb and when you go to WOT all the gas gets sucked out and motor bog down, then when you go off throttle gas fills up again and throttle response comes back.

where are you running the fuel pump pulse line to? need to tap under the reeds for pulse if running AF16 on honda dio with pulse fuel pump.
if you are running CT manifold and using tap above reeds the pump will stop pumping fuel because there is no case pulse above the reeds.
happy tuning

how 120,404.556 = 52.6 stroke?1man8scoots wrote:That is a 120cc. Stroke (Radius squared times pie) =x
X divided by 1000= cc.
Radius squared is your bore divided by 2, then times it self.
27 X 27= 729
729 x 3.14= 2289.06
2289.06 x 120,404.556
120,404.556 ├À 1000= 120.4cc.
thanks for info btw

Re: Ministroke Taida 43.4 ministroke + Corsa fun
I have done over 100 stroked 2 strokes. It is not rocket science but it is a science. Math is part of science. This is a 74cc engine, child's play. If you want 31 degrees of blow down you need 189 ex and 127 transfer. could have been a typo mistake on the transfers i'll keep looking for the paper t...

Re: Ministroke Taida 43.4 ministroke + Corsa fun
I'm interested to know how it's going also. According to my test timing engine and corsas on hand the timing you're looking for wouldn't be done with a simple 1mm base and 1mm up porting of the exhaust. The extra .8mm you added with the fiber gasket and longer stroke you would be over 190 on ex por...

Re: Ministroke Taida 43.4 ministroke + Corsa fun
Get your wheel on the crank, wether it be stator or cvt side, spin the crank to just above the ex port. Loosen the lock nut for the wheel. Just as the edge, or bevel, of the piston reaches the opening of the ex port you will reset your wheel to zero or tdc or bdc it does not matter. Now that it's z...

Re: Picked Up A 2001 Elite Today!
need to pressurize to look for air leaks. i missed a lot of air leaks using the carb cleaner spray method before i made a pressure tester.
carb cleaner only good to find big air leaks

Re: Ministroke Taida 43.4 ministroke + Corsa fun
i usually degree everything before cutting a custom gasket to set port timings correct for the ministroke crank. http://i1068.photobucket.com/albums/u447/rustansouza/Kit%20bike%20build/0512151908a_zpszjtuupr0.jpg after i find the correct base gasket thickness to get the transfer ports to the correct...

Re: Ministroke Taida 43.4 ministroke + Corsa fun
You should probably cut your gasket to match the block and the cylinder to the block, not just block matching to gasket, there's a huge air flow stop in the corners. Picture the air flowing. Minarelli corsas are worse matched. yup the SYM block is smaller the the AF16 so i match gasket to cylinder ...
