pilot sounds useable. check and see what standard was for your year. the reason i recommend checking all bikes you buy is not only so you know for future reference, but jetting down is how the unknowing deal with rising float levels. they will keep jetting down and finally after buying trick heads, exhausts and reeds decide they just cant get their "old bike" to run right, so they sell it. there are people like me that spot those and buy things cheap. there are other people that buy them because they got their ears douched with what a find and great bike is being offered. if the second type of buyer finds out through some merciful act that their problems are float related and fixes them they run the risk of burning a piston once they fix the float situation, if the leaner brass is left in.
FYI bike bandit shows 390-450 listed for sale for that one. most that I see are jetted down some from the lowest offered there as I sated earlier. yours has a different head and it is anyone's guess that that changed, so i think you would be safe to set the float and give it a try. do you know how much clearance you have at the squish area with whatever piston you decided on?
