i'm 3 weeks with an '02 1500 nomad. Same thing. I'm stretching to reach the bars. Most i find are 4 inch risers (2 inch over stock) that give a 1.5 inch pull back. Scootworks phat risers ii show up in all my google searches from a few years ago but their shopping cart doesn't work on the site. I emailed him and he told me he was semi-retired and not making anything at the moment. He does have a set of black ones and they state a 3.5 inch pull back.
I think i am going with a universal baron kit that has various bolts for various applications. Most risers it seems are for harleys and they have a much larger diameter hole in the triple tree. You can get different bolts it seems, and then the inexpensive riser kits are the same cost as those that work with our vn machines.
This is what i'm going with, baron custom accessories kickback riser ba-7410-u (

i didn't realize the nomad was even larger than the classic, plus i have a mustang seat that is a little lower and set back from stock. I can't lean back on the back rest while holding the bars and the slow handling is really difficult plus the sore back from the reach. I'm hoping these solve it before i decide to sell and look for something else. These bigger motor vulcans are quite a bit bigger than most other bikes. I've ridden the c90t and my buddy at the same time i bought my bike bought a yamaha roadstar 1700 that i sat on. What a dramatic difference, i could step over it to get on it and the bars were about perfect for me and it felt 300 lb lighter when i lifted it up off the sidestand. I wish i had looked further, but i was blinded by the i want a bike after 15+ years of having one and jumped on the first nice condition bike i looked at.
