It sounds good, actually.  Admittedly, it doesn't sound as good as that other exhaust.  This one is more throaty where the other one was smoother and quieter.  I'll put that can on the DR, I think.

Couldn't get much more than bog at WOT.  Turns out these VMs had a 190 main jet installed in them.  Way too big.  Dropped down to a 130 and moved the needle up one clip (on ring below center).  It's seems very happy right now.  It's still pretty buzzy though, so I think the carbs are not quite synced.  This big ass sprocket is making it quite the quick shifter.  I'll have to decide how it wants to play and figure out if I need to go smaller.

I tried that on 380, it's LOUD (too loud for British police so I had to make it quieter  ;D )

Haha, this is loud. Not illegal loud, but itís loud. Iím going to work on the baffling to see if I can get it toned down more.

I ran it through some paces in the hills where I grew up. With this sprocket setup, 1st gear is useless on street. Itís super short shifting. Top speed is 80-85mph.

 I think the jetting needs to drop to 120 or 125, if there is a 125. 130 is close, but not quite right. I raised the needle, but I think that was a mistake. Iíll move it back to the middle, run it and see if the clip needs to drop one above center.

Hereís a glamour shot from the weekend on my Grammaís property. An area in the piedmont of upstate, South Carolina nicknamed Dark Corners...

Sharp AF bro.  Some little heat shields will make all the difference.  Mine are just thin stainless and average around 100 degrees w bike at operating temp.

goes up in 2.5 increments

125 127.5 130 132.5 ect till you hit 200

in the video it still sounds a bit boggy or timing late

and if your needle is that high you may want to go a bigger jet needle or needle ?

what do you have and are they both the same

how is your idle to 1/4 mixture

what slide do you have both the same ?

in a small carb like that you may even be in the right range to go to a bleed type jet needle (4 stroke type)

for better atomization and economy at same power levels

they dont make them in the size ranges i usually use but they might for your range
