148 Main Jet, no issues, opinions please.

[125Destroyer]

I have a 93 200 and have the air box lid removed, fmf pipe (gold series) Boyesen reeds and I have been running a 148 main for about 6 or 7 rides now with no issues. I bought the bike used and it had a 150 and only the fmf pipe for mods and the elevation from where I bought it was about 500ft. I live around 3200ft and do most of my riding around this altitude. I am concerned about how lean this is, but do lose power with the 150 back in it. There is no pinging or any other ill effects I have noticed. Opinions?????

Check the color of the plug or the piston wash for correct jetting
