Roadie,
I’ve got the long Bub Slash Cuts too and I love them. I’m going to paint the inside of the ends wrinkle black. They are loud when you open her up, but that’s one of the reasons I brought them.
When the dealer installed them he also installed the Freak and removed the air injectors. He also rejetted my carbs. When I power shift into second I gotta hold on real tight or I’m going off the back. It really flies!
I see a lot of posts about rejetting and changing needles and trying this and that to get rid of popping on deceleration. Mine does pop on decel also it sometimes backfires real loud and even now and then hiccups through the carbs. But I’m not gonna change anything. I like the “backing off” (popping). And the back fires and carb.burping are infrequent enough that I can live with it. It just seems to me that messing with the carbs is a never ending process once started.
