Does anyone know of a site that gives propper sizes to jet carbs for putting on K and N filters? Does one exist?
Any help would be greatly appreciated...

It's all trial and error my friend. Anyone that tells you they have it figured out to exact numbers is selling snake oil. Start with your stock jets, do some test rides and plug chops, and adjust as needed. As an example, my CL350 is bored out 3mm, I ported and polished the head, I'm running velocity stacks, and a make 2 - 1 and I get along fine with the stock CV carbs and stock jetting. Probably a tad lean but it rips at all RPMs without any popping so I may just leave it alone. Good luck.

thanks...that's about what i figured...
 
Right on man. As always, post your findings. Every little bit helps the community here.
 
I have some cheap pods and short mufflers on my 360 and all I did was go up to 105 (from 100) on the main. Still runs a little lean on the top end and pops a little when I deccel only in high rpms though but it took me about 3 months to get the jetting where it is now. Wait I also went up one size on the primary. But anyway from my experience you should get the bike to idle properly first. With stock jets mine was too lean and wouldn't idle below 3000 then I went way up on the main jet and it was too rich still idled way too high. So definitely work your way up in jet sized one at a time. Would've saved me a lot of time and $$$.
