I need to get an aftermarket fuel screw for my 05 525 as it is beyond a pain in the A to get to the stocker. Also, I refuse to buy a tool to adjust my fuel screw! I read somewhere that aluminum fuel screws are not a good idea on these carbs. However, on my CRF 450r I had an MSR aluminum screw and it worked great! The carbs are very similar, whats wrong with an aluminum fuel screw?
