Engine Rebuild Advice
Hey Spanner you're right. Once the motor is finished and I repaint her, I will have an awesome evo and they will be jealous. The 21" wheel and apes, new paint, all the motor work and not to mention it will never look like your everyday, ordinary old heritage classic again, it should be a one of a kind bike. I just put this on my bike check it out its pretty cool. http://boyesen.com/twinshot-vtwin It's a Boyesen twin-shot. I installed it, but not yet tested. I've read a lot of other peoples feedback on google and they all love it and say it makes a huge difference in throttle response, fuel mileage, and with the adjustable fuel jet it, plus my adjustable fuel/air mixture screw and t-handle idle screw, I can take it anywhere in the world and some quick turns of a few *****, I will be able to ride in any weather, at any elevation, I can't wait. I'm considering going to a chain and sprocket drive also to change the ratio, and a wider tire, but I'm not sure what ratio to go with. I have a 5 spd tranny and do most back road riding so I want to keep that torque, but I want to be able to keep up with the 96" and up with 6 spds on the highway. Any advice?

Basically the same thing I'm running on my '92. KB 9.5:1 pistons and an EV 27 cam. You may find that jetting the stock CV isn't easy. Get yourself a TC upgrade kit for that carb. It comes with a needle, emulsion tube and a handful of jets. I switched to the fueling lifters because the stock lifters couldn't keep up with the steep ramps on the 27 and I got too much lifter noise. The KBs require some really delicate break-in procedures due to the smaller clearances between piston and cylinder. A few 1, 2, 5 and then 10 mile rides at first. No motor brakeing, and be very careful not to overheat. Before assembly, flush out everything with diesel (and if you can suck all the oil out of the lower end do that). New oil lines, and be sure to burp the oil pump before even taking it out.
That's my $.02

3.34 is a good gear ratio, HD used it in some occasions to give some giddy up more appealing to the consumer. You will regret anything in the 3.50 range on highway, the engine will live but makes you grit your teeth.
Your going to be surprised on how the Evo responds to some compression and cam, they respond better to mods than the Twinkies so keep going with your direction and going to be fine. If you start getting the power addiction money and splitting compression becomes involved to matching larger cams, head flow, responding exhaust, fine line tuning and the window gets narrow on mistakes with a setup.
Note to yourself when playing with friends: Be alert and match them on the throttle roll and your setup will hold it's own if not pull them and get a WTF, It takes one bada$$ engine to recover from late throttle roll when the boys start letting the dogs out so it doesn't take 100 hp to play, it takes 100 hp to catch 80 hp that already got ahead with Harley engines.

I had a Boyesen Twin-Shot on my Wide Glide and it was awesome....I wish I had swapped it back to standard before the insurance company took it away but I only had one arm working and the thumb on the remaining arm wasn't up to much at the time :-(

IWOMBAT I am taking your word on the tappets, even though Andrews says you can use stock Harley tappets. I had purchased crane tappet roller wheels to replace the stock ones, do you think this will quiet them down? And thanks for the links HARLEY DUDE
