1991 Yamaha WR500 & 1991 Yamaha 650 Lx issues
The 500 I can get running and it seems to run good, but if I shut it off I can't get it running again. It fires right up on the trailer as well, but in the water struggles a little initially.
The 650 will start on the trailer. Once in the water I can't get it to fire.
The were both filled up with marine grade mixed gas and had the plugs changed.
I did a compression test on both of them and took pics of the new plugs
500 I got readings of 130 & 115
650 I got readings of 120 & 10
In the pics the red stripe is the 500. Red, black and gray is the 650
What are some ideas what I should try?
