I just picked up a clean 01 xr650r for $2600. The bike has the stock muffler with what looks to be a removed baffle towards exit of muffler. The side panel is opened up with stock air filter and metal screen, and the carb has a 170 main jet. The bike is hard to start and breaks up in the mid to upper end. If u put the choke at half way the bike will regain upper end. Took carb off and removed pilot and main and clean carb well w/carb clean and blew out transfer ports with shop air, turned fuel screw out 2 turn from stop. Same results and then began pouring fuel out overflow tube. Obviously I have a float issue as well. Wondering if someone would be kind enough to give me stock jet sizes and float height so I can start with a clean slate.
