EV27, stock Evo motor, SE carb - jets advice?

Hi guys

The (crappy stock caged) inner cam bearing started screaming on my '97 RK, fortunately caught it before it killed the cases too. So now it has a new bearing (proper full compliment brg.) and EV27 cam, S&S lifters (old ones were scuffed) and breather gear, and for now the stock CV carb with SE air cleaner.

BUT ... I have an old SE carb (butterfly, rather than CV) in decent condition which came off an Evo Dyna with EV3 cam, which I picked it up at a swap meet for 25 notes. Assuming it's worth spending a coupla hours putting this on in place of the stock CV, I wondered what jets people would suggest I start with?

Thanks for any help

Stick with the CV.....Put a 185 main jet in it and a 48-52 intermediate. Remove the top and the slide cut about 3/4" off the spring in the slide and drill out the air hole in the slide to 1/8". I like to leave the idle mixture screw alone as the bike doesnt care what mods are done while idling and fattening up the idle mixture tends to foul plugs......

Once you are done the bike should start cold much easier. Do not run the choke for very long as we added a bunch of fuel on the intermediate and it will foul the plugs if you leave it idle for long perids with the choke on........
