Standard for 1999 ( no info on 1998 )

55 pilot 

needle 1469mclip 4

main 180

pro circuit

settings

55 pilot

needle 1469m clip 3

main 165

seems like the main was very rich from factory . I would bet that the pilot could drop down a few sizes also

i put in the 180 and 50 and ITS ALIVE!  thank you man. Its a little twitchy I think it needs the power valve adjusted but the ground was wet from rain when I got it together so i put it away and walked away with the win. started up great squirted some stones in first and raced right through the gears.

i think you should look at a leaner main to gain the top end
