help, I'm stumped
Ok, a little help cuz I'm completely stumped.
The problem? A fuel smell when bike is at operating temperature. Not overpowering though...I associate this smell with a rich fuel mixture. The exhaust also has that "running rich" smell.
The good stuff:
1- Still getting same gas milage ~45mpg
2- all 4 spark plugs look great, light tan dry powdery look, (they have about 2000 miles on them since the engine rebuild so they should show it if there were problems)
3- all vent/vacuum hoses and evap canister are hooked up and correct with no leaks
4- exhaust system is all tight. (coasters installed, no popping)
5- hot start is right there
6- 'cold' morning start is good...a little choke action needed but not hard to start at all
7- idle is even and smooth at all operating temps
8- power is good all through engine rpm range, no bogging, choking, or particular flat spot, and responsive to throttle inputs at all rpm and gear selected
9- Fuel mix screws are set at 2 turns
Besides the smell the only other thing it does that I don't think it should is -- when fully heated up the idle speed doesn't fall all the way to 900, it sticks occassionally around 1200-1500.
Should I worry or is this nothing?
