I dont have a 700 but was wondering if the crank from a Frontier 800 4-stroke sled would fit in a sportsman. IE: bore/stroke of a Frontier is 80 x 78 mm where is the 700 is 80 x 68mm..

 

I know the cam will fit but not sure about the crank.

 

i doubt the cam would help any, the frontier is detuned more than a sportsman..

 

From what I've been told it is worth 5-7 hp

 

it will fit but clutch end is longer and will have to be cut and retapered/threaded, also either the pistons (wrist pin location) or rod length will be different, dont know yet.but you could check part nos. on both machines. 700 cranks come complete assembled with rods.

 

You would have to run some type of spacer right??

 

If the case is the same just use the 800 jug...
