I can get a K and N for my 05 650 bf off ebay for 76$ US + 12$ shipping. Is this a good deal? Also, is it worth it. I dont have any mods and probably wont in the future. Any input appreciated.

 

You might feel a little difference but probably not. I mainly run them on myne because I like to be able to clean them and re-use.

My unlce and I bought Honda Ranchers 2 yrs ago. Myne was 4X4 MS and his was 4X4 ES. When we would race them stock for stock we would come out pretty even everytime. I am about 30lbs. heavier. When I put the K&N on my rancher I would beat him every time. When I hit 3rd it would pull out in front of him every time. They say there isn't a diff. but my results show differently.

 

Ren...That price sounds a little high. I paid around $45-50 for my k&n on my 750 and that was with shipping from k&n's website. Unless the filters are different I'm not sure. My 2 cents.
