I decided to remove the 4AGE 20V Silvertop ITB and switched it over to the 04-05 GSXR750 ITB. I find that the gsxr750 are more easier to synchronize and more available in parts as the 4age 20v ITBs are becoming more scarce and prices are going up and will only continue to go up. I also found that it was way more affordable to do the gsxr750 itb (DIY) compare to the 4age 20v itb.
The gsxr750 itb size seem to performed better on the stock engine than the size of the silvertop itb. So make sure to choose the itb size carefully for your engine setup.

Side note: DON'T EXPECT A MASSIVE HP GAIN FROM SIMPLY JUST INSTALLING ITB ON YOUR STOCK ENGINE. YOU MAY GET ZERO OUT OF IT. YOU'LL NEED SOME ENGINE WORK TO IMPROVE SOME HP GAINS OUT OF A ITB SETUP.
