Well there is one problem right off the bat. What if your 84250r had the optional 300cc cylinder and head swap done by its original owner?? the carb size is a 35mm keihn i think. horsepower is....enough to make your eyes water. top speed get on it put ballz to the wall and find out. you should be hitting around 60-70mph i'll leave you a little gap in there to work with.
