Stretched 400
I've been thinking about stretching my 400 for a little now not a big stretch just like 4 inches mainly for looks but I've been noticing everything has said it might decrease power or top speed so I was wondering where I might get an extended swing arm, what some problems might be, and how to get around those problems if possible
Thank you in advance
Edit: I guess what I want isn't actually an extra 4 inches but I would like the center of the back tire to align with the end of the bike I feel it just gives a more flush looked in my opinion any help here would be great thank you
