What are your specs? What jet size....what needles and what clip position?

bike runs strong just getting to soot on tips..

Well the soot on the tips means that your running rich. So I would drop to 152.5's...and see how that is.

Check your float levels too. And a plug chop/read. I've set up others about the same as yours and they ran fine. On the rich side a little maybe.

Thanks everybody for input. The exhaust is good quality and is on the loud side but has a good sound..

Just my opinion but soot on exhaust is completely unavoidable with a carberueted vehicle.

It's gonna be rich somewhere, it's a carburetor, nature of the beast, the tailpipe gives you no idea where it's rich either.

My set up is the same as yours (HMF pipes with ufo slash cuts). I feel it's just a tad rich and will try 152.5s. However, she runs awesome with the cool fall weather!!
