Well, I won't make any major changes/repairs until after winter (around March), but I'm wondering how I can get more speed out of my '77 Bianchi Snark.
Right now, I have a 55 jet, so I'll go down a bit to a 52 (unless there are objections?). I have a 14.12 Dellorto carburator, but some people think I need a larger airbox. How can I tell what size my airbox is to know if I can/should order a bigger one. And would that help?
I know a Biturbo would help me some, too. But is there anything else that would speed me up? Maybe greasing the chain some more? What about sprokets?
I'm currently hitting about 30-32 max on a flat surface after the engine is nice and warm (and w/ no ice/snow on the roads). My average max cruising speed is about 28mph. I'd like to get just over 35mph (which would bury the needle on my speedometer) before the big Memorial Day race.
So ... any advice on speed would be greatly appreciated. Thanks!
