I had this question posed to me. Before now I never thought about it much. While breaking in your motor (this happens to be a 4-stroke) is it recommended to do the proper break-in procedures in "stock" form or can you throw on aftermarket dual exhausts, re-jet and then break in the new bike?My buddy just got his new quad and was told to perform his break-in while the bike was still in its stock form and NOT to put on his dual exhausts that he has until the break-in is done. Does it really make a difference? ANY input would be great, thanks.

 

i would say break it in as is.. then put the mods in it afterwards..

 

no difference wether it is stock or piped it is still going to be broken in depending on how hard u ride it during break in period
