As noted in the .sig, I went from 150 mains to 147.5 today.

Interesting. First thing I noticed is that it took much longer to warm up. At least, I don't think I was THAT impatient to ride. Not a deal breaker, but it did make me wonder at first if I'd gone too far.

Main jets wouldn't affect that. The mains kick in around 6k or 7k IIRC.

If you went from 147.5 to 150 and that was all you did, you did richen the idle and startup. Which might ahve meant faster warm up, faster settling into idle but still not warm enough for the oil to get hot and you to comfortably put stress on it.
You can ride it, but treat it like a cold bike till you get 3-5 mins of riding. It wont stall, it will hold idle without choke but still aint warm enough.
Richer mains will richen the low end too, but not as much a a pilot or air screw will.
1/2 throttle and up is what you'd tune with the mains. Dont go back till you see how its doing there. If its good, but you prefer it to be leaner at idle, use the air screw to lean it.
Cool.

You know, I just realized something. The reason why your and my jetting settings may be different, yet we feel they are both "spot on" could possibly be a factor of how we ride. When I rode the GS I rode it pretty aggressively all the time, which is why the smaller jet sizes may have worked better for me since I was going near-wot for most of the time. You, on the other hand, might not be revving it to the moon every chance you get, and the larger jet size provides the amount of fuel you need at say, half throttle or less.

Maybe?

I'd have tried 20 pilots and 150 mains. same result up high, leaner down low, and you cancompensate idle with air screw.
A GS engine doesn't tell you much unless its really really far off. It will just run hotter and work just fine if you have it leaner. You'd have to have a O2 sensor or do a WFO run under load, hit the kill switch and plug pull and see what it looks like to know its exact jetting.
Cool.

Wrecent,

If you have still have the 62.5 jets hanging around I would be willing to buy them from you.  I am currently at 22.5, 65, 145 (with lunch box and wileyco) and feel that the bike is too rich.  I've mentioned ont he board before that it feels flat in the middle range until about 7k.  I  got alot of responses saying that it was too lean,  but when removing the spark plugs, they were very dark and stunk of gas.  Kinda unrelated, but figured I throw my two cents in.  Let me know about the 62.5 jets.  Thanks!

Set the idle back up to 12-13k, and warm-up is perfectly normal again.

Might be a TAD high (factor of 10)!!
