I am working on a friends 2004 GS500F with drop in K&N with restricter and stock exhaust. I have 132.5 mains and 20 pilots but I am having a hard time finding 62.5 mid mains. If anybody has them I would like to purchase them from you. The bike has the hanging idle issue but only has 1500 miles on it. Have cleaned the carbs and gas tank due to sitting for so long and I have been reading on here about all the solutions to this problem. The website is great as well as the forum, very helpfull.
The usual trick is to put 65 mids in it, but there was a sudco part number for 62.5 somewhere - try the FAQ 2nd page.
Cool.
