EtrnlSoldier, just call up The MOTORHEAD a/k/a Dennis, he is the moderator for this website, shouldn't be too hard too find.
SUPERBIKEMIKE I have one on order, I will let you know how the fit and appearance is when it comes in. You can get them painted for all BUSA years. As for trimming, that is to the bike itself, not the undertail. But it's easy.
BTW did you know there is an actual SUPERBIKEMIKE, as in SUPERBIKEMIKE.com, he sells BUSA motors, throttlebodies, Hi RPM ECU and Big Block Kits.
I will post some pics once I get it on.
