hey guys, long story short i am looking to get a 13 tooth front sprocket for my 98 F3. I would prefer 520, what bike(s) use the same splines? I cant seem to find the straight answer anywhere. Thanks!

 

ebay had a couple of 13t for 520 chain. Early Hurricane takes the same sprockets as F2 and F3. Will hit the swingarm guard and cut through it pretty quickly. Could add teeth to rear.

 

we actually have the engine in a drag racing lawn mower... can only go up 2 in the back since we are already running a 50T there. (the back is an axle from a yamaha tri-z 3 wheeler)

it is quite the machine, search youtube for "Tyler Ochs" and you should be able to find my channel

btw i ended up getting one from denniskirk that was for a F2, could have went as low as a 12T but i think that will start to give us issues at that point..
