Contact PCW Racing or Morleys Muscle. Either can get you setup with a 1500cc Gen1 vmax.
Unless you truly love the vmax, you'd probably be better off selling it and buying something else. Maybe a gen 2. It would definitely be cheaper than trying to make the Gen1 substantially faster.

This is exctly the conclusion I came to when I looked into this. If you want one to compete with a Gen2 then the price will easily exceed a Gen2. That said there is one on CL locally with almost no miles, ecu tume and exhaust, seat, only tasteful grown up mods for $11k. If you want more CC you can go to a Venture engine, 1300 were found in Gen1 MKII (86-93). Earlier were 1200cc. A couple different ratios but Ive read its a difference you can feel. Not sure its enough to get where you want to be.
One other thought, not sure what you've done with your Gen1 but when I bought mine it was stock aside from a Kerker 4-2-1 and a "professionally" installed DJ stage 1 jet kit. It was fast and all but I did feel it wasnt matching the hype. It took a lot of tuning, with help from folks here. I added COPs and a Morley jet kit with filter lid. Once I got the right jets and proper setup it was like a different animal and the investment was minimal. Im now very pleased. I know a Gen2 would dust me but its still a kick to ride.
If I wanted more power I would take this warmed up Rocket III off a friend, its cheaper than a Gen2 and has had a cam /head rework. The torque is absurd, there is only so much you can ask motorcycle tires to do. If you want a stupid fast cruiser the RIII needs consideration. I bought a Hinkley era Triumph new on 2000 and enjoyed 80k trouble free miles, best bike I have ever owned, the old school Triumph gremlins gone. The mods not really cheap but I stumble across then now and again already modded and priced right. Just another way to get where you wanna be if the Gen2 max doesnt strike you right. Just my .02¢.
After getting my Gen1 max sorted I decided that its plenty quick for me, as opposed to before it was dialed in. I now enjoy the Vmax experience that was dulled by bad jetting/tuning. I recall feeling just what you described, I feel so much better now that she does deliver the Vmax experience.
