Installed my yosh slip on this weekend with K&N power kit used dyno jets set up 144-146 for jetting machine improved in acceleration for sure but thought top end would be more compared to stock, on GPS top end on asphalt road with wind behind my back was 79 mph which is pretty fast but just did,nt seem to pull as hard as I thought, I am pleased with it overall, I compared to my friends stock raptor on all testing, just thought someone would like to know!
