I agree .. I have a YD100 and my son has the Zeda 80 with DIO REED etc .. and his is faster … I have 36tooth and he has 44 .. mine is still only on second tank
Now I know you said 65 jet was on yours, but when I left the stock jet in and was going almost full throttle, bike would cut out on me .. then I installed a 70 and it was a smidge better … I have 70-75 jets coming .. but I also found a non marketed jet in my box which looked visibly bigger and I installed it .. no more cutting out at full throttle but now im guessing its too rich … will have to wait for the Jets to come in so I can go to a 71 or so
