If you havent changed the intake side, it wont be too far from stock jetting. Id go up one on the pilot jet, and up one or two on the main.
Heres agood article on jetting, and it describes the symptoms of lean and rich, and you can make the changes based on that,

Not sure on your elevation, but I run a 155 Mikuni main(probably should run a 157) w/ a 25 pilot. 800 above sea level. Also, HMF has a jetting specs. on their website.
