Taller Gears For 300

Randomly thinking about 300 hondas with 54% gear reductions and how slow the top speed must be. Lots of 250es and 250sx parts will interchange with 300 fourtrax. Alot of guys are taking 300 2wd motors changing the angle output drive countershaft that runs thru the transmission with the 250es and sx motors and putting them in there 3wheelers. You have to change them to get the drive shaft to line up better. The 250es and 250sx have different transmission gears the es is lower geared same ratios as 300 the sx is taller due to smaller tires. Knowing the trans gears will interchange with es,sx,and 300 one could take just the 5th gears from the sx and put it on a 300 for a taller "road gear" without loosing any bottom end. 5th final drive would go from .84 to .90 My question is what mph gain do you think it would have?

    Many variables here. Which diff? Which tranny? Which motor? Which gears in which motor on which tranny? Any combination would make totally different outcomes.

    You lost me here.lol Im talking about taking 5th gear from an atc 250sx transmission and swapping it in a 300 fourtrax. 5th gear in a 250sx is .84  300 fourtrax is .90

    Ok what I'm saying in a nut shell is as similar as some parts are most are still different maybe not by a lot but some. So unless all the parts on both bikes are the same except for fifth gear then it would be easy to figure the new top speed but if not then better get your calculator out. So really the only true way is to do it and let us know the outcome.
