Is there anyone that has the exact gear ratios for a 2001 300ex i lost my manual just when i needed it most. I need the primary, secondary, and 1st-5th ratios.

thanks

front13

rear 38

i sugguest 14 front and 36 rear helps out with top speed and the big gap between gears isnt as noticeable.

stock 56 mph
with 14/36 67mph (open exhaust)

14/36 is the most common like he said, if you get the 14 tooth front you will have to grind down the case saver a little so it can clear, no big deal though

I see this mentioned alot. Is there enough ground off to compromise the strength of the case saver?

No.. you only need to remove like a 1/16th of an inch of material.

To get back on topic.. I beleive the origional poster is looking for transmission ratios.. not sprocket sizes.

yeah i need the gear ratios. im getting ready to install a 350 big bore and make it a race quad so i need the gear ratios to figure out what comprimises im gonna have to make so that it doesnt rev out so quick the factory rev box sucks badly.
