6 gears is too many for vintage racing
(used to have only 4 on my 71 r75/5 racebike..)
Was going to use a 400 head and have it done up nice by mike.
But as I said, there just wasnt a reasonable class for it in Oregon.
Track days will keep you busy for a while, but I'd be willing to bet that you will wanting to start competing.
It's lots of fun. I don't race any more, before my accident, I was out at the track every race day, with my racer Jon on his Duc, and helping dark horse racing with their sv650's. And, as I said, getting a 350t ready for the v5 class for Jon to race.
It's super addictive.
You may need to find a bike that you can race competitively with once you get into it. I like vintage because we can do a lot of the work ourselves, we arent going 200mph, and well, vintage bikes are cool as hell.
Enjoy yourself. looking forward to more of your track adventures.
