Stak did you mean .020 to .030, because 0.30 is 5/16" almost, and that is one thick washer!

 

YEAH, I am NOT a good person with keyboard spelling, hit the wrong letters alot, put period's in the wrong place.LOL .020-.030 is what I meant.....

 

so should i get 145 main or just put .020 washers under stock neddles.
Stakk if i were to richen my pilot srews would i turn them out or in.

if your speedo is 68 I would'nt touch the main's. I would put one .020 shim (washer) UNDER each needle to raise it slightly, some are going as much as .040, but the way your's is running I think .020 will be fine, turn your pilot screw's to the left(counterclockwise) to richen, let it idle warmed up and do one carb until it runs rough then turn the other way until it clear's up, usually turning one full turn clockwise after it loads up will take care of it, you must richen them until you reach the point that they load and run rough, to assure you are rich enough, then you simply lean them just enough to smooth it out, I do this and never count the number of turn's , there's no point, as all bikes are different.....
